Overview As a Steelworker, you will be expected to become familiar with the Plasma Arc Cutting (PAC) process. To achieve optimum performance of your plasma cutting system, first you must know what plasma is and understand the basic plasma cutting process. Plasma is a physical state of matter. In fact, plasma is the most abundant form of matter in the universe. Physical matter may be found in four states: solid, liquid, gas, or plasma. Changes from one physical state to another occur by either adding or removing energy. Plasma looks and behaves like a high temperature gas, but with an important difference: it conducts electricity. Lightning is a naturally occurring example of plasma. A plasma arc is created by electrically heating a gas to a very high temperature; this ionizes the atoms, which enables the gas to conduct electricity. This is the major difference between a neutral gas and plasma; the particles in plasma can exert electromagnetic forces on one another. This chapter will present an introductory explanation of plasma arc cutting. Since the Navy supply system purchases equipment from different manufacturers, always refer to the manufacturer’s manuals for specific operating and maintenance instructions. Objectives When you have completed this chapter, you will be able to do the following: 1. Describe the Plasma Arc Cutting process. 2. Describe plasma arc equipment and consumables. 3. Identify the plasma cutting and gouging sequence. 4. Describe the steps in arc gouging. 5. Identify the steps of a quality plasma cut. 6. Describe the safety procedures for plasma arc processes.

100 PLASMA ARC CUTTING PROCESS Plasma arc cutting is such a simple process you could almost take it out of the box and start using it However as with any piece of equipment you need to know how and why it does what it does and the necessary precautions to do the job safely

110 Description Materials in nature exist in one of four different states solid liquid gas or plasma Plasma is very rare on Earth because of its very high temperature however most of the matter in the universe is plasma The Sun stars and galaxies are made of plasma On Earth you will find naturally occurring plasma in lightning and a few other places (Figure 7-1) Neon tubes and florescent lights generate low-temperature plasma It is the energy from ionization that you are actually seeing

Experiments with plasma arcs date back to early in the twentieth century but it was in the 1950s when PAC torches were patented The equipment was large and bulky and used a variety of cutting and cooling gases Today the introduction of cutting with clean compressed air or nitrogen is replacing many other types of cutting equipment Temperature makes the difference between water ice liquid water and water vapor In each of these states temperature energy pushes the molecules of water away from each other to change the waterrsquos state At very high temperature and pressure the water molecules themselves break apart and the atoms begin to ionize Normal atoms consist of protons and neutrons in a nucleus surrounded by a cloud of electrons In plasma the negatively charged electrons separate from the nucleus leaving behind their positively charged nuclei known as ions When the fast-moving electrons collide with other electrons and ions they release vast amounts of energy This energy is what gives plasma its cutting

power Plasma cutters work by electrically charging a gas within a plenum (chamber) that surrounds the electrode (Figure 7-2) This charge superheats and ionizes the gas which is now a greatly expanded (in volume and pressure) plasma gas The electrically charged plasma then exits the torch nozzle through a constricting orifice and arcs to the surface of the grounded workpiece creating a stream of directed plasma approximately 30000deg F (16649deg C) moving at approximately 20000 feet per second (6096 msec) reducing metal to molten slag The plasma itself conducts electrical current The cycle of creating the arc is continuous as long as power is supplied to the electrode and the plasma stays in contact with the grounded metal being cut The PAC process uses this high temperature high velocity jet of gas (exiting from the constricting orifice of the torch tip) to melt a localized area and removes the molten material by the force of the plasma jet The force of the arc pushes the molten metal through the workpiece and severs the material (Figure 7-3) You can make extremely clean and accurate cuts with PAC and because of the tightly focused heat energy there is very little warping even when cutting thin sheet metal PAC also offers quality gouging and piercing capabilities

120 Plasma vs Oxy-Fuel Cutting Before the PAC process became commonplace if you wanted to cut carbon steel stainless steel or aluminum chances were you would be using several means or methods of cutting Perhaps you would use oxy-fuel gas flame cutting for steel but that process is not recommended for cutting stainless steel and aluminum due to the formation of an oxide that prevents oxidation from fully occurring You could use bandsaws shears abrasive cut-off wheels or power hacksaws but you would need special blades to cut the stainless steels and alloy steels With engineering advances in PAC equipment all metals that conduct electricity whether they are common or exotic metals can be cut economically with one process Since the plasma arc cutting process is capable of hand-held or machine torch cutting metals ranging from thin gauge aluminum to 1 12-inch carbon or stainless steel can be plasma cut It can be used in many applications including stack and shape cutting beveling gouging and piercing in all positions The PAC process is used in industries such as metal fabrication construction maintenance metal salvage (scrap and recycling) automotive repair metal art and sculpting The PAC process is compared primarily to the oxy-fuel gas cutting (OFC) process The OFC process severs or removes metal by the chemical reaction of oxidation It is known as ldquoburningrdquo or rapid oxidation This occurs when you apply pure oxygen to hot preheated metal and maintain the elevated temperature with a flame from a burning oxy-fuel gas mixture It requires a high purity oxygen and fuel gas which comprises an explosive fuel gas mixture usually supplied from high-pressure compressed gas cylinders

A properly installed Air Plasma Arc Cutting setup can be safer than an OFC system Safety precautions on the PAC torches can be safer than oxy-fuel gas torches where there is a chance of flashback and the danger of flammable gases in exposed hoses (Figure 7-4) OFCrsquos advantage is its capability of cutting very thick carbon steel with relatively inexpensive equipment that does not require electricity OFCrsquos disadvantage is its recommended limitation to cut carbon steels only PAC requires minimum training to operate the equipment safely and efficiently One of PACrsquos major advantages is speed PAC operates at a much higher heat energy level so it cuts faster than OFC especially on metal less than 2 inches thick and cutting speed makes a significant difference in production time and operator comfort Also unlike the OFC process PAC does not require preheating another major advantage besides the faster cutting speed Because of this PAC results in less distortion of the metal being cut This is due also to a very narrow heat-affected zone (area changed in characteristics near the cut) The clean dross-free cut produced with the PAC process can eliminate the secondary operations of other cutting methods such as cleaning up rough edges and dross on the bottom or backside of the cut (Figure 7-5) When compared to OFC PAC in some areas will not be as portable due to its dependence on primary electrical power from a utility line or engine-driven generator

A It has a greater atomic weight B It is incandescent C It can conduct electricity D It has a distinct odor

200 EQUIPMENT and CONSUMABLES A pilot arc between the electrode and the constricting tip initiates the plasma arc process The tip is connected to ground through a current-limiting resistor and a pilot arc relay contact in the torch assembly One of two methods either a high frequency generator connected to the electrode and tip or an internal contact start initiates the pilot arc The welding power supply then maintains a low current arc inside the torch

Ionized orifice gas from the pilot arc is blown through the constricting tip orifice by a compressed gas This forms a low resistance path to ignite the main arc between the electrode and the workpiece (Figure 7-6) When the main arc ignites the pilot arc relay may be opened automatically to avoid unnecessary heating of the constricting tip which helps extend the life of the tip and electrode

210 Equipment Requirements A typical air-cooled PAC system consists of the following components

bull Power source

bull Either a hand-held or a machine-style torch

bull Supply of compressed air or nitrogen

211 Power Source Plasma arc cutting uses a direct current power source The polarity setting for the power source is direct current electrode negative (DCEN) In most systems there is also a positive connection to the torch tip in which the current is limited by a resistor This circuit establishes a pilot arc which then establishes the cutting arc The power source is a constant current power source with a high open circuit voltage (250-400 volts) The amperage is usually adjustable within the range of the power

Figure 7-6 mdash Basic PAC setup

NAVEDTRA 14250A 7-7

source and amperage is directly proportional to the thickness and speed in which the metal can be cut Most manual PAC systems now use switch-mode or inverter technology These sophisticated electronically-controlled or microprocessor-controlled devices are better able to tolerate variations in line voltage take more abuse in the field and deliver better cutting performance while consuming less power with a longer duty cycle The term ldquoduty cyclerdquo identifies the number of minutes out of a 10-minute period that you can operate a plasma cutter at its rated capacity For example a 300-amp welder with a 60 duty could operate at 300 amps for 6 minutes and then needs to cool with its fan running for 4 minutes Manufacturers rate their products based on ambient air temperature so if a cutter is rated at 104ordm F and the ambient temperature where you are working is 84ordm F the duty cycle of the machine increases Conversely if the ambient temperature is hotter than the manufacturerrsquos initial rating the duty cycle decreases You need to know what ambient temperature the manufacturer used to rate its PAC in order to operate the equipment at the appropriate duty cycle and prevent damage

212 Rated Cutting Capacity Selection of the PAC is based on the type and thickness of the metal to be cut and the speed at which the metal needs to be cut The higher the PAC ampere and duty cycle rating the thicker and faster it will cut (Figure 7-7) While there is no standard for PAC cutting speeds in the weldingcutting industry some manufacturing companies qualify their PAC rated cutting capacity by three (3) standards (Figure 7-8)

Figure 7-7 mdash Cutting capacity rating

Figure 7-8 mdash Rated cutting capacity

NAVEDTRA 14250A 7-8

bull Rated Cutting Capacity at ten (10) inches per minute travel speed is considered the minimum speed at which an operator achieves a smooth steady cut using a hand-held torch at the machinersquos Rated Output

bull Maximum Quality Cutting Capacity is a good quality cut that is achieved at

slower than ten (10) inches per minute travel speed

bull Sever Cut Capacity is the maximum metal thickness cut achieved in ideal conditions Sever Cut does not include allowances for rating quality of cut or travel speed

213 Cutting Speed As indicated previously the cutting speed will affect the thickness of the material that can be cut The slower you move the torch the thicker the material that can be cut but if you move the torch too slow the plasma arc will remove all of the material directly underneath it and the arc will bend to the side of the kerf causing a jagged cut The faster the travel speeds the thinner the material that can be cut but if you increase the torch speed too much the torch will be unable to cut completely through the workpiece Cutting speed is measured in inches per minute Maximum cutting speed is determined by the arc current nozzle diameter and metal thickness

220 Consumables The plasma torch is designed to generate and focus the plasma cutting arc (Figure 7-9)

In either hand held or machine torches the same parts are used an electrode to carry the current from the power source a swirl ring to spin the compressed air a tip that constricts and focuses the cutting arc and a shield and retaining ring to protect the torch

221 Swirl Ring The swirl ring made of a high temperature plastic is designed with angled holes to spin the cutting gas in a vortex (Figure 7-10) Spinning the gas centers the arc on the electrode and helps control and constrict the arc as it passes through the tip Some plasma cutting equipment swirls the gas in a clockwise direction others in a counter-

Figure 7-10 mdash Swirl ring

Figure 7-9 mdash PAC torch assembly

Figure 7-10 mdash Swirl ring NAVEDTRA 14250A 7-9

clockwise direction Check the manufacturerrsquos manual the direction of flow will indicate which side of the cut will be beveled

222 Electrode The purpose of the electrode is to provide a path for the electricity from the power source and generate the cutting arc (Figure7-11) The electrode is typically made of copper with an insert made of hafnium The hafnium-alloyed electrodes have good wear life when you use clean dry compressed air or nitrogen although electrode consumption may be greater with air plasma than with nitrogen

223 Tip The purpose of the torch tip is to constrict and focus the plasma arc (Figure 7-12) Constricting the arc increases the energy density and velocity The tips are made of copper with a specifically sized hole or orifice in the center of the tip Tips are sized according to the amperage rating of their respective torch

224 Retaining Cup The retaining cup serves two functions (Figure 7-13) First it holds the other consumable parts firmly in place Second it insulates and keeps the other consumable parts from making contact with the work piece

225 Shields There are two types of shields used on plasma torches a drag shield (Figure 7-14) and a deflector (Figure 7-15) The drag shield insulates the front end of the torch from the work piece and protects the torch tip from spatter The deflector insulates the electrode and protects it from spatter It is used when extended cutting consumables are needed

NAVEDTRA 14250A 7-10

226 Consumables Used During Extended Cutting vs Drag Cutting The use of extended cutting consumables requires the operator to maintain a torch standoff of about 18 ldquoTorch stand-offrdquo is the distance from the outer face of the torch tip or constricting orifice nozzle to the base metal surface (Figure 7-16) Extended cutting is used in situations where the operator needs extra control of the cutting arc such as when cutting in a corner or when a machine torch is used The drag shield is constructed so that the required standoff is maintained inside the torch Using drag cutting consumables allows the operator to drag the torch on the work piece while cutting at full output which increases operator comfort and makes template cutting easier Figure 7-16 mdash Extended vs drag

NAVEDTRA 14250A 7-11

227 Consumable Tips for Different Amperages Tip size is directly proportionate to amperage the higher the amperage the larger the tip you would use As you can see in Figure 7-17 the 40-amp tip opening is smaller than the 80-amp tip Exercise caution and be sure to use the correct tip for the amperage If you use an 80-amp tip for a 40-amp machine the plasma arc will not constrict enough and will cut an uneven wide kerf If you use a 40-amp tip on an 80-amp machine internal arcing will damage the tip and electrode decreasing their service life

Figure 7-17 mdash Consumables chart

NAVEDTRA 14250A 7-12

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

Figure 7-19 mdash Consumable inspection process

Figure 7-18 mdash New and worn consumables

NAVEDTRA 14250A 7-13

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

Figure 7-20 mdash Cutting gasses

NAVEDTRA 14250A 7-14

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

Figure 7-28 mdash Pierce cut process

Figure 7-29 mdash Gouging tips

Figure 7-27 mdash Pierce cut

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

Figure 7-30 mdash Gouging process

NAVEDTRA 14250A 7-20

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

Figure 7-32 mdash Direction of cut Figure 7-31 mdash Elements of a quality cut

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

100 PLASMA ARC CUTTING PROCESS Plasma arc cutting is such a simple process you could almost take it out of the box and start using it However as with any piece of equipment you need to know how and why it does what it does and the necessary precautions to do the job safely

110 Description Materials in nature exist in one of four different states solid liquid gas or plasma Plasma is very rare on Earth because of its very high temperature however most of the matter in the universe is plasma The Sun stars and galaxies are made of plasma On Earth you will find naturally occurring plasma in lightning and a few other places (Figure 7-1) Neon tubes and florescent lights generate low-temperature plasma It is the energy from ionization that you are actually seeing

Experiments with plasma arcs date back to early in the twentieth century but it was in the 1950s when PAC torches were patented The equipment was large and bulky and used a variety of cutting and cooling gases Today the introduction of cutting with clean compressed air or nitrogen is replacing many other types of cutting equipment Temperature makes the difference between water ice liquid water and water vapor In each of these states temperature energy pushes the molecules of water away from each other to change the waterrsquos state At very high temperature and pressure the water molecules themselves break apart and the atoms begin to ionize Normal atoms consist of protons and neutrons in a nucleus surrounded by a cloud of electrons In plasma the negatively charged electrons separate from the nucleus leaving behind their positively charged nuclei known as ions When the fast-moving electrons collide with other electrons and ions they release vast amounts of energy This energy is what gives plasma its cutting

power Plasma cutters work by electrically charging a gas within a plenum (chamber) that surrounds the electrode (Figure 7-2) This charge superheats and ionizes the gas which is now a greatly expanded (in volume and pressure) plasma gas The electrically charged plasma then exits the torch nozzle through a constricting orifice and arcs to the surface of the grounded workpiece creating a stream of directed plasma approximately 30000deg F (16649deg C) moving at approximately 20000 feet per second (6096 msec) reducing metal to molten slag The plasma itself conducts electrical current The cycle of creating the arc is continuous as long as power is supplied to the electrode and the plasma stays in contact with the grounded metal being cut The PAC process uses this high temperature high velocity jet of gas (exiting from the constricting orifice of the torch tip) to melt a localized area and removes the molten material by the force of the plasma jet The force of the arc pushes the molten metal through the workpiece and severs the material (Figure 7-3) You can make extremely clean and accurate cuts with PAC and because of the tightly focused heat energy there is very little warping even when cutting thin sheet metal PAC also offers quality gouging and piercing capabilities

120 Plasma vs Oxy-Fuel Cutting Before the PAC process became commonplace if you wanted to cut carbon steel stainless steel or aluminum chances were you would be using several means or methods of cutting Perhaps you would use oxy-fuel gas flame cutting for steel but that process is not recommended for cutting stainless steel and aluminum due to the formation of an oxide that prevents oxidation from fully occurring You could use bandsaws shears abrasive cut-off wheels or power hacksaws but you would need special blades to cut the stainless steels and alloy steels With engineering advances in PAC equipment all metals that conduct electricity whether they are common or exotic metals can be cut economically with one process Since the plasma arc cutting process is capable of hand-held or machine torch cutting metals ranging from thin gauge aluminum to 1 12-inch carbon or stainless steel can be plasma cut It can be used in many applications including stack and shape cutting beveling gouging and piercing in all positions The PAC process is used in industries such as metal fabrication construction maintenance metal salvage (scrap and recycling) automotive repair metal art and sculpting The PAC process is compared primarily to the oxy-fuel gas cutting (OFC) process The OFC process severs or removes metal by the chemical reaction of oxidation It is known as ldquoburningrdquo or rapid oxidation This occurs when you apply pure oxygen to hot preheated metal and maintain the elevated temperature with a flame from a burning oxy-fuel gas mixture It requires a high purity oxygen and fuel gas which comprises an explosive fuel gas mixture usually supplied from high-pressure compressed gas cylinders

A properly installed Air Plasma Arc Cutting setup can be safer than an OFC system Safety precautions on the PAC torches can be safer than oxy-fuel gas torches where there is a chance of flashback and the danger of flammable gases in exposed hoses (Figure 7-4) OFCrsquos advantage is its capability of cutting very thick carbon steel with relatively inexpensive equipment that does not require electricity OFCrsquos disadvantage is its recommended limitation to cut carbon steels only PAC requires minimum training to operate the equipment safely and efficiently One of PACrsquos major advantages is speed PAC operates at a much higher heat energy level so it cuts faster than OFC especially on metal less than 2 inches thick and cutting speed makes a significant difference in production time and operator comfort Also unlike the OFC process PAC does not require preheating another major advantage besides the faster cutting speed Because of this PAC results in less distortion of the metal being cut This is due also to a very narrow heat-affected zone (area changed in characteristics near the cut) The clean dross-free cut produced with the PAC process can eliminate the secondary operations of other cutting methods such as cleaning up rough edges and dross on the bottom or backside of the cut (Figure 7-5) When compared to OFC PAC in some areas will not be as portable due to its dependence on primary electrical power from a utility line or engine-driven generator

A It has a greater atomic weight B It is incandescent C It can conduct electricity D It has a distinct odor

200 EQUIPMENT and CONSUMABLES A pilot arc between the electrode and the constricting tip initiates the plasma arc process The tip is connected to ground through a current-limiting resistor and a pilot arc relay contact in the torch assembly One of two methods either a high frequency generator connected to the electrode and tip or an internal contact start initiates the pilot arc The welding power supply then maintains a low current arc inside the torch

Ionized orifice gas from the pilot arc is blown through the constricting tip orifice by a compressed gas This forms a low resistance path to ignite the main arc between the electrode and the workpiece (Figure 7-6) When the main arc ignites the pilot arc relay may be opened automatically to avoid unnecessary heating of the constricting tip which helps extend the life of the tip and electrode

210 Equipment Requirements A typical air-cooled PAC system consists of the following components

bull Power source

bull Either a hand-held or a machine-style torch

bull Supply of compressed air or nitrogen

211 Power Source Plasma arc cutting uses a direct current power source The polarity setting for the power source is direct current electrode negative (DCEN) In most systems there is also a positive connection to the torch tip in which the current is limited by a resistor This circuit establishes a pilot arc which then establishes the cutting arc The power source is a constant current power source with a high open circuit voltage (250-400 volts) The amperage is usually adjustable within the range of the power

Figure 7-6 mdash Basic PAC setup

NAVEDTRA 14250A 7-7

source and amperage is directly proportional to the thickness and speed in which the metal can be cut Most manual PAC systems now use switch-mode or inverter technology These sophisticated electronically-controlled or microprocessor-controlled devices are better able to tolerate variations in line voltage take more abuse in the field and deliver better cutting performance while consuming less power with a longer duty cycle The term ldquoduty cyclerdquo identifies the number of minutes out of a 10-minute period that you can operate a plasma cutter at its rated capacity For example a 300-amp welder with a 60 duty could operate at 300 amps for 6 minutes and then needs to cool with its fan running for 4 minutes Manufacturers rate their products based on ambient air temperature so if a cutter is rated at 104ordm F and the ambient temperature where you are working is 84ordm F the duty cycle of the machine increases Conversely if the ambient temperature is hotter than the manufacturerrsquos initial rating the duty cycle decreases You need to know what ambient temperature the manufacturer used to rate its PAC in order to operate the equipment at the appropriate duty cycle and prevent damage

212 Rated Cutting Capacity Selection of the PAC is based on the type and thickness of the metal to be cut and the speed at which the metal needs to be cut The higher the PAC ampere and duty cycle rating the thicker and faster it will cut (Figure 7-7) While there is no standard for PAC cutting speeds in the weldingcutting industry some manufacturing companies qualify their PAC rated cutting capacity by three (3) standards (Figure 7-8)

Figure 7-7 mdash Cutting capacity rating

Figure 7-8 mdash Rated cutting capacity

NAVEDTRA 14250A 7-8

bull Rated Cutting Capacity at ten (10) inches per minute travel speed is considered the minimum speed at which an operator achieves a smooth steady cut using a hand-held torch at the machinersquos Rated Output

bull Maximum Quality Cutting Capacity is a good quality cut that is achieved at

slower than ten (10) inches per minute travel speed

bull Sever Cut Capacity is the maximum metal thickness cut achieved in ideal conditions Sever Cut does not include allowances for rating quality of cut or travel speed

213 Cutting Speed As indicated previously the cutting speed will affect the thickness of the material that can be cut The slower you move the torch the thicker the material that can be cut but if you move the torch too slow the plasma arc will remove all of the material directly underneath it and the arc will bend to the side of the kerf causing a jagged cut The faster the travel speeds the thinner the material that can be cut but if you increase the torch speed too much the torch will be unable to cut completely through the workpiece Cutting speed is measured in inches per minute Maximum cutting speed is determined by the arc current nozzle diameter and metal thickness

220 Consumables The plasma torch is designed to generate and focus the plasma cutting arc (Figure 7-9)

In either hand held or machine torches the same parts are used an electrode to carry the current from the power source a swirl ring to spin the compressed air a tip that constricts and focuses the cutting arc and a shield and retaining ring to protect the torch

221 Swirl Ring The swirl ring made of a high temperature plastic is designed with angled holes to spin the cutting gas in a vortex (Figure 7-10) Spinning the gas centers the arc on the electrode and helps control and constrict the arc as it passes through the tip Some plasma cutting equipment swirls the gas in a clockwise direction others in a counter-

Figure 7-10 mdash Swirl ring NAVEDTRA 14250A 7-9

clockwise direction Check the manufacturerrsquos manual the direction of flow will indicate which side of the cut will be beveled

222 Electrode The purpose of the electrode is to provide a path for the electricity from the power source and generate the cutting arc (Figure7-11) The electrode is typically made of copper with an insert made of hafnium The hafnium-alloyed electrodes have good wear life when you use clean dry compressed air or nitrogen although electrode consumption may be greater with air plasma than with nitrogen

223 Tip The purpose of the torch tip is to constrict and focus the plasma arc (Figure 7-12) Constricting the arc increases the energy density and velocity The tips are made of copper with a specifically sized hole or orifice in the center of the tip Tips are sized according to the amperage rating of their respective torch

224 Retaining Cup The retaining cup serves two functions (Figure 7-13) First it holds the other consumable parts firmly in place Second it insulates and keeps the other consumable parts from making contact with the work piece

225 Shields There are two types of shields used on plasma torches a drag shield (Figure 7-14) and a deflector (Figure 7-15) The drag shield insulates the front end of the torch from the work piece and protects the torch tip from spatter The deflector insulates the electrode and protects it from spatter It is used when extended cutting consumables are needed

NAVEDTRA 14250A 7-10

226 Consumables Used During Extended Cutting vs Drag Cutting The use of extended cutting consumables requires the operator to maintain a torch standoff of about 18 ldquoTorch stand-offrdquo is the distance from the outer face of the torch tip or constricting orifice nozzle to the base metal surface (Figure 7-16) Extended cutting is used in situations where the operator needs extra control of the cutting arc such as when cutting in a corner or when a machine torch is used The drag shield is constructed so that the required standoff is maintained inside the torch Using drag cutting consumables allows the operator to drag the torch on the work piece while cutting at full output which increases operator comfort and makes template cutting easier Figure 7-16 mdash Extended vs drag

NAVEDTRA 14250A 7-11

227 Consumable Tips for Different Amperages Tip size is directly proportionate to amperage the higher the amperage the larger the tip you would use As you can see in Figure 7-17 the 40-amp tip opening is smaller than the 80-amp tip Exercise caution and be sure to use the correct tip for the amperage If you use an 80-amp tip for a 40-amp machine the plasma arc will not constrict enough and will cut an uneven wide kerf If you use a 40-amp tip on an 80-amp machine internal arcing will damage the tip and electrode decreasing their service life

NAVEDTRA 14250A 7-12

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

Figure 7-18 mdash New and worn consumables

NAVEDTRA 14250A 7-13

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

A Excess plasma formation B Resolidified molten metal C Angle on the top of a cut D Preferred shielding material

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

100 PLASMA ARC CUTTING PROCESS Plasma arc cutting is such a simple process you could almost take it out of the box and start using it However as with any piece of equipment you need to know how and why it does what it does and the necessary precautions to do the job safely

110 Description Materials in nature exist in one of four different states solid liquid gas or plasma Plasma is very rare on Earth because of its very high temperature however most of the matter in the universe is plasma The Sun stars and galaxies are made of plasma On Earth you will find naturally occurring plasma in lightning and a few other places (Figure 7-1) Neon tubes and florescent lights generate low-temperature plasma It is the energy from ionization that you are actually seeing

Experiments with plasma arcs date back to early in the twentieth century but it was in the 1950s when PAC torches were patented The equipment was large and bulky and used a variety of cutting and cooling gases Today the introduction of cutting with clean compressed air or nitrogen is replacing many other types of cutting equipment Temperature makes the difference between water ice liquid water and water vapor In each of these states temperature energy pushes the molecules of water away from each other to change the waterrsquos state At very high temperature and pressure the water molecules themselves break apart and the atoms begin to ionize Normal atoms consist of protons and neutrons in a nucleus surrounded by a cloud of electrons In plasma the negatively charged electrons separate from the nucleus leaving behind their positively charged nuclei known as ions When the fast-moving electrons collide with other electrons and ions they release vast amounts of energy This energy is what gives plasma its cutting

power Plasma cutters work by electrically charging a gas within a plenum (chamber) that surrounds the electrode (Figure 7-2) This charge superheats and ionizes the gas which is now a greatly expanded (in volume and pressure) plasma gas The electrically charged plasma then exits the torch nozzle through a constricting orifice and arcs to the surface of the grounded workpiece creating a stream of directed plasma approximately 30000deg F (16649deg C) moving at approximately 20000 feet per second (6096 msec) reducing metal to molten slag The plasma itself conducts electrical current The cycle of creating the arc is continuous as long as power is supplied to the electrode and the plasma stays in contact with the grounded metal being cut The PAC process uses this high temperature high velocity jet of gas (exiting from the constricting orifice of the torch tip) to melt a localized area and removes the molten material by the force of the plasma jet The force of the arc pushes the molten metal through the workpiece and severs the material (Figure 7-3) You can make extremely clean and accurate cuts with PAC and because of the tightly focused heat energy there is very little warping even when cutting thin sheet metal PAC also offers quality gouging and piercing capabilities

120 Plasma vs Oxy-Fuel Cutting Before the PAC process became commonplace if you wanted to cut carbon steel stainless steel or aluminum chances were you would be using several means or methods of cutting Perhaps you would use oxy-fuel gas flame cutting for steel but that process is not recommended for cutting stainless steel and aluminum due to the formation of an oxide that prevents oxidation from fully occurring You could use bandsaws shears abrasive cut-off wheels or power hacksaws but you would need special blades to cut the stainless steels and alloy steels With engineering advances in PAC equipment all metals that conduct electricity whether they are common or exotic metals can be cut economically with one process Since the plasma arc cutting process is capable of hand-held or machine torch cutting metals ranging from thin gauge aluminum to 1 12-inch carbon or stainless steel can be plasma cut It can be used in many applications including stack and shape cutting beveling gouging and piercing in all positions The PAC process is used in industries such as metal fabrication construction maintenance metal salvage (scrap and recycling) automotive repair metal art and sculpting The PAC process is compared primarily to the oxy-fuel gas cutting (OFC) process The OFC process severs or removes metal by the chemical reaction of oxidation It is known as ldquoburningrdquo or rapid oxidation This occurs when you apply pure oxygen to hot preheated metal and maintain the elevated temperature with a flame from a burning oxy-fuel gas mixture It requires a high purity oxygen and fuel gas which comprises an explosive fuel gas mixture usually supplied from high-pressure compressed gas cylinders

A properly installed Air Plasma Arc Cutting setup can be safer than an OFC system Safety precautions on the PAC torches can be safer than oxy-fuel gas torches where there is a chance of flashback and the danger of flammable gases in exposed hoses (Figure 7-4) OFCrsquos advantage is its capability of cutting very thick carbon steel with relatively inexpensive equipment that does not require electricity OFCrsquos disadvantage is its recommended limitation to cut carbon steels only PAC requires minimum training to operate the equipment safely and efficiently One of PACrsquos major advantages is speed PAC operates at a much higher heat energy level so it cuts faster than OFC especially on metal less than 2 inches thick and cutting speed makes a significant difference in production time and operator comfort Also unlike the OFC process PAC does not require preheating another major advantage besides the faster cutting speed Because of this PAC results in less distortion of the metal being cut This is due also to a very narrow heat-affected zone (area changed in characteristics near the cut) The clean dross-free cut produced with the PAC process can eliminate the secondary operations of other cutting methods such as cleaning up rough edges and dross on the bottom or backside of the cut (Figure 7-5) When compared to OFC PAC in some areas will not be as portable due to its dependence on primary electrical power from a utility line or engine-driven generator

A It has a greater atomic weight B It is incandescent C It can conduct electricity D It has a distinct odor

200 EQUIPMENT and CONSUMABLES A pilot arc between the electrode and the constricting tip initiates the plasma arc process The tip is connected to ground through a current-limiting resistor and a pilot arc relay contact in the torch assembly One of two methods either a high frequency generator connected to the electrode and tip or an internal contact start initiates the pilot arc The welding power supply then maintains a low current arc inside the torch

Ionized orifice gas from the pilot arc is blown through the constricting tip orifice by a compressed gas This forms a low resistance path to ignite the main arc between the electrode and the workpiece (Figure 7-6) When the main arc ignites the pilot arc relay may be opened automatically to avoid unnecessary heating of the constricting tip which helps extend the life of the tip and electrode

210 Equipment Requirements A typical air-cooled PAC system consists of the following components

bull Power source

bull Either a hand-held or a machine-style torch

bull Supply of compressed air or nitrogen

211 Power Source Plasma arc cutting uses a direct current power source The polarity setting for the power source is direct current electrode negative (DCEN) In most systems there is also a positive connection to the torch tip in which the current is limited by a resistor This circuit establishes a pilot arc which then establishes the cutting arc The power source is a constant current power source with a high open circuit voltage (250-400 volts) The amperage is usually adjustable within the range of the power

Figure 7-6 mdash Basic PAC setup

NAVEDTRA 14250A 7-7

source and amperage is directly proportional to the thickness and speed in which the metal can be cut Most manual PAC systems now use switch-mode or inverter technology These sophisticated electronically-controlled or microprocessor-controlled devices are better able to tolerate variations in line voltage take more abuse in the field and deliver better cutting performance while consuming less power with a longer duty cycle The term ldquoduty cyclerdquo identifies the number of minutes out of a 10-minute period that you can operate a plasma cutter at its rated capacity For example a 300-amp welder with a 60 duty could operate at 300 amps for 6 minutes and then needs to cool with its fan running for 4 minutes Manufacturers rate their products based on ambient air temperature so if a cutter is rated at 104ordm F and the ambient temperature where you are working is 84ordm F the duty cycle of the machine increases Conversely if the ambient temperature is hotter than the manufacturerrsquos initial rating the duty cycle decreases You need to know what ambient temperature the manufacturer used to rate its PAC in order to operate the equipment at the appropriate duty cycle and prevent damage

212 Rated Cutting Capacity Selection of the PAC is based on the type and thickness of the metal to be cut and the speed at which the metal needs to be cut The higher the PAC ampere and duty cycle rating the thicker and faster it will cut (Figure 7-7) While there is no standard for PAC cutting speeds in the weldingcutting industry some manufacturing companies qualify their PAC rated cutting capacity by three (3) standards (Figure 7-8)

Figure 7-7 mdash Cutting capacity rating

Figure 7-8 mdash Rated cutting capacity

NAVEDTRA 14250A 7-8

bull Rated Cutting Capacity at ten (10) inches per minute travel speed is considered the minimum speed at which an operator achieves a smooth steady cut using a hand-held torch at the machinersquos Rated Output

bull Maximum Quality Cutting Capacity is a good quality cut that is achieved at

slower than ten (10) inches per minute travel speed

bull Sever Cut Capacity is the maximum metal thickness cut achieved in ideal conditions Sever Cut does not include allowances for rating quality of cut or travel speed

213 Cutting Speed As indicated previously the cutting speed will affect the thickness of the material that can be cut The slower you move the torch the thicker the material that can be cut but if you move the torch too slow the plasma arc will remove all of the material directly underneath it and the arc will bend to the side of the kerf causing a jagged cut The faster the travel speeds the thinner the material that can be cut but if you increase the torch speed too much the torch will be unable to cut completely through the workpiece Cutting speed is measured in inches per minute Maximum cutting speed is determined by the arc current nozzle diameter and metal thickness

220 Consumables The plasma torch is designed to generate and focus the plasma cutting arc (Figure 7-9)

In either hand held or machine torches the same parts are used an electrode to carry the current from the power source a swirl ring to spin the compressed air a tip that constricts and focuses the cutting arc and a shield and retaining ring to protect the torch

221 Swirl Ring The swirl ring made of a high temperature plastic is designed with angled holes to spin the cutting gas in a vortex (Figure 7-10) Spinning the gas centers the arc on the electrode and helps control and constrict the arc as it passes through the tip Some plasma cutting equipment swirls the gas in a clockwise direction others in a counter-

Figure 7-10 mdash Swirl ring NAVEDTRA 14250A 7-9

clockwise direction Check the manufacturerrsquos manual the direction of flow will indicate which side of the cut will be beveled

222 Electrode The purpose of the electrode is to provide a path for the electricity from the power source and generate the cutting arc (Figure7-11) The electrode is typically made of copper with an insert made of hafnium The hafnium-alloyed electrodes have good wear life when you use clean dry compressed air or nitrogen although electrode consumption may be greater with air plasma than with nitrogen

223 Tip The purpose of the torch tip is to constrict and focus the plasma arc (Figure 7-12) Constricting the arc increases the energy density and velocity The tips are made of copper with a specifically sized hole or orifice in the center of the tip Tips are sized according to the amperage rating of their respective torch

224 Retaining Cup The retaining cup serves two functions (Figure 7-13) First it holds the other consumable parts firmly in place Second it insulates and keeps the other consumable parts from making contact with the work piece

225 Shields There are two types of shields used on plasma torches a drag shield (Figure 7-14) and a deflector (Figure 7-15) The drag shield insulates the front end of the torch from the work piece and protects the torch tip from spatter The deflector insulates the electrode and protects it from spatter It is used when extended cutting consumables are needed

NAVEDTRA 14250A 7-10

226 Consumables Used During Extended Cutting vs Drag Cutting The use of extended cutting consumables requires the operator to maintain a torch standoff of about 18 ldquoTorch stand-offrdquo is the distance from the outer face of the torch tip or constricting orifice nozzle to the base metal surface (Figure 7-16) Extended cutting is used in situations where the operator needs extra control of the cutting arc such as when cutting in a corner or when a machine torch is used The drag shield is constructed so that the required standoff is maintained inside the torch Using drag cutting consumables allows the operator to drag the torch on the work piece while cutting at full output which increases operator comfort and makes template cutting easier Figure 7-16 mdash Extended vs drag

NAVEDTRA 14250A 7-11

227 Consumable Tips for Different Amperages Tip size is directly proportionate to amperage the higher the amperage the larger the tip you would use As you can see in Figure 7-17 the 40-amp tip opening is smaller than the 80-amp tip Exercise caution and be sure to use the correct tip for the amperage If you use an 80-amp tip for a 40-amp machine the plasma arc will not constrict enough and will cut an uneven wide kerf If you use a 40-amp tip on an 80-amp machine internal arcing will damage the tip and electrode decreasing their service life

NAVEDTRA 14250A 7-12

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

NAVEDTRA 14250A 7-13

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

A Excess plasma formation B Resolidified molten metal C Angle on the top of a cut D Preferred shielding material

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

100 PLASMA ARC CUTTING PROCESS Plasma arc cutting is such a simple process you could almost take it out of the box and start using it However as with any piece of equipment you need to know how and why it does what it does and the necessary precautions to do the job safely

110 Description Materials in nature exist in one of four different states solid liquid gas or plasma Plasma is very rare on Earth because of its very high temperature however most of the matter in the universe is plasma The Sun stars and galaxies are made of plasma On Earth you will find naturally occurring plasma in lightning and a few other places (Figure 7-1) Neon tubes and florescent lights generate low-temperature plasma It is the energy from ionization that you are actually seeing

Experiments with plasma arcs date back to early in the twentieth century but it was in the 1950s when PAC torches were patented The equipment was large and bulky and used a variety of cutting and cooling gases Today the introduction of cutting with clean compressed air or nitrogen is replacing many other types of cutting equipment Temperature makes the difference between water ice liquid water and water vapor In each of these states temperature energy pushes the molecules of water away from each other to change the waterrsquos state At very high temperature and pressure the water molecules themselves break apart and the atoms begin to ionize Normal atoms consist of protons and neutrons in a nucleus surrounded by a cloud of electrons In plasma the negatively charged electrons separate from the nucleus leaving behind their positively charged nuclei known as ions When the fast-moving electrons collide with other electrons and ions they release vast amounts of energy This energy is what gives plasma its cutting

power Plasma cutters work by electrically charging a gas within a plenum (chamber) that surrounds the electrode (Figure 7-2) This charge superheats and ionizes the gas which is now a greatly expanded (in volume and pressure) plasma gas The electrically charged plasma then exits the torch nozzle through a constricting orifice and arcs to the surface of the grounded workpiece creating a stream of directed plasma approximately 30000deg F (16649deg C) moving at approximately 20000 feet per second (6096 msec) reducing metal to molten slag The plasma itself conducts electrical current The cycle of creating the arc is continuous as long as power is supplied to the electrode and the plasma stays in contact with the grounded metal being cut The PAC process uses this high temperature high velocity jet of gas (exiting from the constricting orifice of the torch tip) to melt a localized area and removes the molten material by the force of the plasma jet The force of the arc pushes the molten metal through the workpiece and severs the material (Figure 7-3) You can make extremely clean and accurate cuts with PAC and because of the tightly focused heat energy there is very little warping even when cutting thin sheet metal PAC also offers quality gouging and piercing capabilities

120 Plasma vs Oxy-Fuel Cutting Before the PAC process became commonplace if you wanted to cut carbon steel stainless steel or aluminum chances were you would be using several means or methods of cutting Perhaps you would use oxy-fuel gas flame cutting for steel but that process is not recommended for cutting stainless steel and aluminum due to the formation of an oxide that prevents oxidation from fully occurring You could use bandsaws shears abrasive cut-off wheels or power hacksaws but you would need special blades to cut the stainless steels and alloy steels With engineering advances in PAC equipment all metals that conduct electricity whether they are common or exotic metals can be cut economically with one process Since the plasma arc cutting process is capable of hand-held or machine torch cutting metals ranging from thin gauge aluminum to 1 12-inch carbon or stainless steel can be plasma cut It can be used in many applications including stack and shape cutting beveling gouging and piercing in all positions The PAC process is used in industries such as metal fabrication construction maintenance metal salvage (scrap and recycling) automotive repair metal art and sculpting The PAC process is compared primarily to the oxy-fuel gas cutting (OFC) process The OFC process severs or removes metal by the chemical reaction of oxidation It is known as ldquoburningrdquo or rapid oxidation This occurs when you apply pure oxygen to hot preheated metal and maintain the elevated temperature with a flame from a burning oxy-fuel gas mixture It requires a high purity oxygen and fuel gas which comprises an explosive fuel gas mixture usually supplied from high-pressure compressed gas cylinders

A properly installed Air Plasma Arc Cutting setup can be safer than an OFC system Safety precautions on the PAC torches can be safer than oxy-fuel gas torches where there is a chance of flashback and the danger of flammable gases in exposed hoses (Figure 7-4) OFCrsquos advantage is its capability of cutting very thick carbon steel with relatively inexpensive equipment that does not require electricity OFCrsquos disadvantage is its recommended limitation to cut carbon steels only PAC requires minimum training to operate the equipment safely and efficiently One of PACrsquos major advantages is speed PAC operates at a much higher heat energy level so it cuts faster than OFC especially on metal less than 2 inches thick and cutting speed makes a significant difference in production time and operator comfort Also unlike the OFC process PAC does not require preheating another major advantage besides the faster cutting speed Because of this PAC results in less distortion of the metal being cut This is due also to a very narrow heat-affected zone (area changed in characteristics near the cut) The clean dross-free cut produced with the PAC process can eliminate the secondary operations of other cutting methods such as cleaning up rough edges and dross on the bottom or backside of the cut (Figure 7-5) When compared to OFC PAC in some areas will not be as portable due to its dependence on primary electrical power from a utility line or engine-driven generator

2 What characteristic makes plasma different than a gas

A It has a greater atomic weight B It is incandescent C It can conduct electricity D It has a distinct odor

200 EQUIPMENT and CONSUMABLES A pilot arc between the electrode and the constricting tip initiates the plasma arc process The tip is connected to ground through a current-limiting resistor and a pilot arc relay contact in the torch assembly One of two methods either a high frequency generator connected to the electrode and tip or an internal contact start initiates the pilot arc The welding power supply then maintains a low current arc inside the torch

Ionized orifice gas from the pilot arc is blown through the constricting tip orifice by a compressed gas This forms a low resistance path to ignite the main arc between the electrode and the workpiece (Figure 7-6) When the main arc ignites the pilot arc relay may be opened automatically to avoid unnecessary heating of the constricting tip which helps extend the life of the tip and electrode

210 Equipment Requirements A typical air-cooled PAC system consists of the following components

bull Power source

bull Either a hand-held or a machine-style torch

bull Supply of compressed air or nitrogen

211 Power Source Plasma arc cutting uses a direct current power source The polarity setting for the power source is direct current electrode negative (DCEN) In most systems there is also a positive connection to the torch tip in which the current is limited by a resistor This circuit establishes a pilot arc which then establishes the cutting arc The power source is a constant current power source with a high open circuit voltage (250-400 volts) The amperage is usually adjustable within the range of the power

Figure 7-6 mdash Basic PAC setup

NAVEDTRA 14250A 7-7

source and amperage is directly proportional to the thickness and speed in which the metal can be cut Most manual PAC systems now use switch-mode or inverter technology These sophisticated electronically-controlled or microprocessor-controlled devices are better able to tolerate variations in line voltage take more abuse in the field and deliver better cutting performance while consuming less power with a longer duty cycle The term ldquoduty cyclerdquo identifies the number of minutes out of a 10-minute period that you can operate a plasma cutter at its rated capacity For example a 300-amp welder with a 60 duty could operate at 300 amps for 6 minutes and then needs to cool with its fan running for 4 minutes Manufacturers rate their products based on ambient air temperature so if a cutter is rated at 104ordm F and the ambient temperature where you are working is 84ordm F the duty cycle of the machine increases Conversely if the ambient temperature is hotter than the manufacturerrsquos initial rating the duty cycle decreases You need to know what ambient temperature the manufacturer used to rate its PAC in order to operate the equipment at the appropriate duty cycle and prevent damage

212 Rated Cutting Capacity Selection of the PAC is based on the type and thickness of the metal to be cut and the speed at which the metal needs to be cut The higher the PAC ampere and duty cycle rating the thicker and faster it will cut (Figure 7-7) While there is no standard for PAC cutting speeds in the weldingcutting industry some manufacturing companies qualify their PAC rated cutting capacity by three (3) standards (Figure 7-8)

Figure 7-7 mdash Cutting capacity rating

Figure 7-8 mdash Rated cutting capacity

NAVEDTRA 14250A 7-8

bull Rated Cutting Capacity at ten (10) inches per minute travel speed is considered the minimum speed at which an operator achieves a smooth steady cut using a hand-held torch at the machinersquos Rated Output

bull Maximum Quality Cutting Capacity is a good quality cut that is achieved at

slower than ten (10) inches per minute travel speed

bull Sever Cut Capacity is the maximum metal thickness cut achieved in ideal conditions Sever Cut does not include allowances for rating quality of cut or travel speed

213 Cutting Speed As indicated previously the cutting speed will affect the thickness of the material that can be cut The slower you move the torch the thicker the material that can be cut but if you move the torch too slow the plasma arc will remove all of the material directly underneath it and the arc will bend to the side of the kerf causing a jagged cut The faster the travel speeds the thinner the material that can be cut but if you increase the torch speed too much the torch will be unable to cut completely through the workpiece Cutting speed is measured in inches per minute Maximum cutting speed is determined by the arc current nozzle diameter and metal thickness

220 Consumables The plasma torch is designed to generate and focus the plasma cutting arc (Figure 7-9)

In either hand held or machine torches the same parts are used an electrode to carry the current from the power source a swirl ring to spin the compressed air a tip that constricts and focuses the cutting arc and a shield and retaining ring to protect the torch

221 Swirl Ring The swirl ring made of a high temperature plastic is designed with angled holes to spin the cutting gas in a vortex (Figure 7-10) Spinning the gas centers the arc on the electrode and helps control and constrict the arc as it passes through the tip Some plasma cutting equipment swirls the gas in a clockwise direction others in a counter-

Figure 7-9 mdash PAC torch assembly

Figure 7-10 mdash Swirl ring NAVEDTRA 14250A 7-9

clockwise direction Check the manufacturerrsquos manual the direction of flow will indicate which side of the cut will be beveled

222 Electrode The purpose of the electrode is to provide a path for the electricity from the power source and generate the cutting arc (Figure7-11) The electrode is typically made of copper with an insert made of hafnium The hafnium-alloyed electrodes have good wear life when you use clean dry compressed air or nitrogen although electrode consumption may be greater with air plasma than with nitrogen

223 Tip The purpose of the torch tip is to constrict and focus the plasma arc (Figure 7-12) Constricting the arc increases the energy density and velocity The tips are made of copper with a specifically sized hole or orifice in the center of the tip Tips are sized according to the amperage rating of their respective torch

224 Retaining Cup The retaining cup serves two functions (Figure 7-13) First it holds the other consumable parts firmly in place Second it insulates and keeps the other consumable parts from making contact with the work piece

225 Shields There are two types of shields used on plasma torches a drag shield (Figure 7-14) and a deflector (Figure 7-15) The drag shield insulates the front end of the torch from the work piece and protects the torch tip from spatter The deflector insulates the electrode and protects it from spatter It is used when extended cutting consumables are needed

NAVEDTRA 14250A 7-10

226 Consumables Used During Extended Cutting vs Drag Cutting The use of extended cutting consumables requires the operator to maintain a torch standoff of about 18 ldquoTorch stand-offrdquo is the distance from the outer face of the torch tip or constricting orifice nozzle to the base metal surface (Figure 7-16) Extended cutting is used in situations where the operator needs extra control of the cutting arc such as when cutting in a corner or when a machine torch is used The drag shield is constructed so that the required standoff is maintained inside the torch Using drag cutting consumables allows the operator to drag the torch on the work piece while cutting at full output which increases operator comfort and makes template cutting easier Figure 7-16 mdash Extended vs drag

NAVEDTRA 14250A 7-11

227 Consumable Tips for Different Amperages Tip size is directly proportionate to amperage the higher the amperage the larger the tip you would use As you can see in Figure 7-17 the 40-amp tip opening is smaller than the 80-amp tip Exercise caution and be sure to use the correct tip for the amperage If you use an 80-amp tip for a 40-amp machine the plasma arc will not constrict enough and will cut an uneven wide kerf If you use a 40-amp tip on an 80-amp machine internal arcing will damage the tip and electrode decreasing their service life

NAVEDTRA 14250A 7-12

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

NAVEDTRA 14250A 7-13

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

A Excess plasma formation B Resolidified molten metal C Angle on the top of a cut D Preferred shielding material

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

power Plasma cutters work by electrically charging a gas within a plenum (chamber) that surrounds the electrode (Figure 7-2) This charge superheats and ionizes the gas which is now a greatly expanded (in volume and pressure) plasma gas The electrically charged plasma then exits the torch nozzle through a constricting orifice and arcs to the surface of the grounded workpiece creating a stream of directed plasma approximately 30000deg F (16649deg C) moving at approximately 20000 feet per second (6096 msec) reducing metal to molten slag The plasma itself conducts electrical current The cycle of creating the arc is continuous as long as power is supplied to the electrode and the plasma stays in contact with the grounded metal being cut The PAC process uses this high temperature high velocity jet of gas (exiting from the constricting orifice of the torch tip) to melt a localized area and removes the molten material by the force of the plasma jet The force of the arc pushes the molten metal through the workpiece and severs the material (Figure 7-3) You can make extremely clean and accurate cuts with PAC and because of the tightly focused heat energy there is very little warping even when cutting thin sheet metal PAC also offers quality gouging and piercing capabilities

120 Plasma vs Oxy-Fuel Cutting Before the PAC process became commonplace if you wanted to cut carbon steel stainless steel or aluminum chances were you would be using several means or methods of cutting Perhaps you would use oxy-fuel gas flame cutting for steel but that process is not recommended for cutting stainless steel and aluminum due to the formation of an oxide that prevents oxidation from fully occurring You could use bandsaws shears abrasive cut-off wheels or power hacksaws but you would need special blades to cut the stainless steels and alloy steels With engineering advances in PAC equipment all metals that conduct electricity whether they are common or exotic metals can be cut economically with one process Since the plasma arc cutting process is capable of hand-held or machine torch cutting metals ranging from thin gauge aluminum to 1 12-inch carbon or stainless steel can be plasma cut It can be used in many applications including stack and shape cutting beveling gouging and piercing in all positions The PAC process is used in industries such as metal fabrication construction maintenance metal salvage (scrap and recycling) automotive repair metal art and sculpting The PAC process is compared primarily to the oxy-fuel gas cutting (OFC) process The OFC process severs or removes metal by the chemical reaction of oxidation It is known as ldquoburningrdquo or rapid oxidation This occurs when you apply pure oxygen to hot preheated metal and maintain the elevated temperature with a flame from a burning oxy-fuel gas mixture It requires a high purity oxygen and fuel gas which comprises an explosive fuel gas mixture usually supplied from high-pressure compressed gas cylinders

A properly installed Air Plasma Arc Cutting setup can be safer than an OFC system Safety precautions on the PAC torches can be safer than oxy-fuel gas torches where there is a chance of flashback and the danger of flammable gases in exposed hoses (Figure 7-4) OFCrsquos advantage is its capability of cutting very thick carbon steel with relatively inexpensive equipment that does not require electricity OFCrsquos disadvantage is its recommended limitation to cut carbon steels only PAC requires minimum training to operate the equipment safely and efficiently One of PACrsquos major advantages is speed PAC operates at a much higher heat energy level so it cuts faster than OFC especially on metal less than 2 inches thick and cutting speed makes a significant difference in production time and operator comfort Also unlike the OFC process PAC does not require preheating another major advantage besides the faster cutting speed Because of this PAC results in less distortion of the metal being cut This is due also to a very narrow heat-affected zone (area changed in characteristics near the cut) The clean dross-free cut produced with the PAC process can eliminate the secondary operations of other cutting methods such as cleaning up rough edges and dross on the bottom or backside of the cut (Figure 7-5) When compared to OFC PAC in some areas will not be as portable due to its dependence on primary electrical power from a utility line or engine-driven generator

A It has a greater atomic weight B It is incandescent C It can conduct electricity D It has a distinct odor

200 EQUIPMENT and CONSUMABLES A pilot arc between the electrode and the constricting tip initiates the plasma arc process The tip is connected to ground through a current-limiting resistor and a pilot arc relay contact in the torch assembly One of two methods either a high frequency generator connected to the electrode and tip or an internal contact start initiates the pilot arc The welding power supply then maintains a low current arc inside the torch

Ionized orifice gas from the pilot arc is blown through the constricting tip orifice by a compressed gas This forms a low resistance path to ignite the main arc between the electrode and the workpiece (Figure 7-6) When the main arc ignites the pilot arc relay may be opened automatically to avoid unnecessary heating of the constricting tip which helps extend the life of the tip and electrode

210 Equipment Requirements A typical air-cooled PAC system consists of the following components

bull Power source

bull Either a hand-held or a machine-style torch

bull Supply of compressed air or nitrogen

211 Power Source Plasma arc cutting uses a direct current power source The polarity setting for the power source is direct current electrode negative (DCEN) In most systems there is also a positive connection to the torch tip in which the current is limited by a resistor This circuit establishes a pilot arc which then establishes the cutting arc The power source is a constant current power source with a high open circuit voltage (250-400 volts) The amperage is usually adjustable within the range of the power

Figure 7-6 mdash Basic PAC setup

NAVEDTRA 14250A 7-7

source and amperage is directly proportional to the thickness and speed in which the metal can be cut Most manual PAC systems now use switch-mode or inverter technology These sophisticated electronically-controlled or microprocessor-controlled devices are better able to tolerate variations in line voltage take more abuse in the field and deliver better cutting performance while consuming less power with a longer duty cycle The term ldquoduty cyclerdquo identifies the number of minutes out of a 10-minute period that you can operate a plasma cutter at its rated capacity For example a 300-amp welder with a 60 duty could operate at 300 amps for 6 minutes and then needs to cool with its fan running for 4 minutes Manufacturers rate their products based on ambient air temperature so if a cutter is rated at 104ordm F and the ambient temperature where you are working is 84ordm F the duty cycle of the machine increases Conversely if the ambient temperature is hotter than the manufacturerrsquos initial rating the duty cycle decreases You need to know what ambient temperature the manufacturer used to rate its PAC in order to operate the equipment at the appropriate duty cycle and prevent damage

212 Rated Cutting Capacity Selection of the PAC is based on the type and thickness of the metal to be cut and the speed at which the metal needs to be cut The higher the PAC ampere and duty cycle rating the thicker and faster it will cut (Figure 7-7) While there is no standard for PAC cutting speeds in the weldingcutting industry some manufacturing companies qualify their PAC rated cutting capacity by three (3) standards (Figure 7-8)

Figure 7-7 mdash Cutting capacity rating

Figure 7-8 mdash Rated cutting capacity

NAVEDTRA 14250A 7-8

bull Rated Cutting Capacity at ten (10) inches per minute travel speed is considered the minimum speed at which an operator achieves a smooth steady cut using a hand-held torch at the machinersquos Rated Output

bull Maximum Quality Cutting Capacity is a good quality cut that is achieved at

slower than ten (10) inches per minute travel speed

bull Sever Cut Capacity is the maximum metal thickness cut achieved in ideal conditions Sever Cut does not include allowances for rating quality of cut or travel speed

213 Cutting Speed As indicated previously the cutting speed will affect the thickness of the material that can be cut The slower you move the torch the thicker the material that can be cut but if you move the torch too slow the plasma arc will remove all of the material directly underneath it and the arc will bend to the side of the kerf causing a jagged cut The faster the travel speeds the thinner the material that can be cut but if you increase the torch speed too much the torch will be unable to cut completely through the workpiece Cutting speed is measured in inches per minute Maximum cutting speed is determined by the arc current nozzle diameter and metal thickness

220 Consumables The plasma torch is designed to generate and focus the plasma cutting arc (Figure 7-9)

In either hand held or machine torches the same parts are used an electrode to carry the current from the power source a swirl ring to spin the compressed air a tip that constricts and focuses the cutting arc and a shield and retaining ring to protect the torch

221 Swirl Ring The swirl ring made of a high temperature plastic is designed with angled holes to spin the cutting gas in a vortex (Figure 7-10) Spinning the gas centers the arc on the electrode and helps control and constrict the arc as it passes through the tip Some plasma cutting equipment swirls the gas in a clockwise direction others in a counter-

Figure 7-9 mdash PAC torch assembly

Figure 7-10 mdash Swirl ring NAVEDTRA 14250A 7-9

clockwise direction Check the manufacturerrsquos manual the direction of flow will indicate which side of the cut will be beveled

222 Electrode The purpose of the electrode is to provide a path for the electricity from the power source and generate the cutting arc (Figure7-11) The electrode is typically made of copper with an insert made of hafnium The hafnium-alloyed electrodes have good wear life when you use clean dry compressed air or nitrogen although electrode consumption may be greater with air plasma than with nitrogen

223 Tip The purpose of the torch tip is to constrict and focus the plasma arc (Figure 7-12) Constricting the arc increases the energy density and velocity The tips are made of copper with a specifically sized hole or orifice in the center of the tip Tips are sized according to the amperage rating of their respective torch

224 Retaining Cup The retaining cup serves two functions (Figure 7-13) First it holds the other consumable parts firmly in place Second it insulates and keeps the other consumable parts from making contact with the work piece

225 Shields There are two types of shields used on plasma torches a drag shield (Figure 7-14) and a deflector (Figure 7-15) The drag shield insulates the front end of the torch from the work piece and protects the torch tip from spatter The deflector insulates the electrode and protects it from spatter It is used when extended cutting consumables are needed

226 Consumables Used During Extended Cutting vs Drag Cutting The use of extended cutting consumables requires the operator to maintain a torch standoff of about 18 ldquoTorch stand-offrdquo is the distance from the outer face of the torch tip or constricting orifice nozzle to the base metal surface (Figure 7-16) Extended cutting is used in situations where the operator needs extra control of the cutting arc such as when cutting in a corner or when a machine torch is used The drag shield is constructed so that the required standoff is maintained inside the torch Using drag cutting consumables allows the operator to drag the torch on the work piece while cutting at full output which increases operator comfort and makes template cutting easier Figure 7-16 mdash Extended vs drag

NAVEDTRA 14250A 7-11

227 Consumable Tips for Different Amperages Tip size is directly proportionate to amperage the higher the amperage the larger the tip you would use As you can see in Figure 7-17 the 40-amp tip opening is smaller than the 80-amp tip Exercise caution and be sure to use the correct tip for the amperage If you use an 80-amp tip for a 40-amp machine the plasma arc will not constrict enough and will cut an uneven wide kerf If you use a 40-amp tip on an 80-amp machine internal arcing will damage the tip and electrode decreasing their service life

NAVEDTRA 14250A 7-12

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

NAVEDTRA 14250A 7-13

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

A Excess plasma formation B Resolidified molten metal C Angle on the top of a cut D Preferred shielding material

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

A properly installed Air Plasma Arc Cutting setup can be safer than an OFC system Safety precautions on the PAC torches can be safer than oxy-fuel gas torches where there is a chance of flashback and the danger of flammable gases in exposed hoses (Figure 7-4) OFCrsquos advantage is its capability of cutting very thick carbon steel with relatively inexpensive equipment that does not require electricity OFCrsquos disadvantage is its recommended limitation to cut carbon steels only PAC requires minimum training to operate the equipment safely and efficiently One of PACrsquos major advantages is speed PAC operates at a much higher heat energy level so it cuts faster than OFC especially on metal less than 2 inches thick and cutting speed makes a significant difference in production time and operator comfort Also unlike the OFC process PAC does not require preheating another major advantage besides the faster cutting speed Because of this PAC results in less distortion of the metal being cut This is due also to a very narrow heat-affected zone (area changed in characteristics near the cut) The clean dross-free cut produced with the PAC process can eliminate the secondary operations of other cutting methods such as cleaning up rough edges and dross on the bottom or backside of the cut (Figure 7-5) When compared to OFC PAC in some areas will not be as portable due to its dependence on primary electrical power from a utility line or engine-driven generator

A It has a greater atomic weight B It is incandescent C It can conduct electricity D It has a distinct odor

200 EQUIPMENT and CONSUMABLES A pilot arc between the electrode and the constricting tip initiates the plasma arc process The tip is connected to ground through a current-limiting resistor and a pilot arc relay contact in the torch assembly One of two methods either a high frequency generator connected to the electrode and tip or an internal contact start initiates the pilot arc The welding power supply then maintains a low current arc inside the torch

Ionized orifice gas from the pilot arc is blown through the constricting tip orifice by a compressed gas This forms a low resistance path to ignite the main arc between the electrode and the workpiece (Figure 7-6) When the main arc ignites the pilot arc relay may be opened automatically to avoid unnecessary heating of the constricting tip which helps extend the life of the tip and electrode

210 Equipment Requirements A typical air-cooled PAC system consists of the following components

bull Power source

bull Either a hand-held or a machine-style torch

bull Supply of compressed air or nitrogen

211 Power Source Plasma arc cutting uses a direct current power source The polarity setting for the power source is direct current electrode negative (DCEN) In most systems there is also a positive connection to the torch tip in which the current is limited by a resistor This circuit establishes a pilot arc which then establishes the cutting arc The power source is a constant current power source with a high open circuit voltage (250-400 volts) The amperage is usually adjustable within the range of the power

Figure 7-6 mdash Basic PAC setup

NAVEDTRA 14250A 7-7

source and amperage is directly proportional to the thickness and speed in which the metal can be cut Most manual PAC systems now use switch-mode or inverter technology These sophisticated electronically-controlled or microprocessor-controlled devices are better able to tolerate variations in line voltage take more abuse in the field and deliver better cutting performance while consuming less power with a longer duty cycle The term ldquoduty cyclerdquo identifies the number of minutes out of a 10-minute period that you can operate a plasma cutter at its rated capacity For example a 300-amp welder with a 60 duty could operate at 300 amps for 6 minutes and then needs to cool with its fan running for 4 minutes Manufacturers rate their products based on ambient air temperature so if a cutter is rated at 104ordm F and the ambient temperature where you are working is 84ordm F the duty cycle of the machine increases Conversely if the ambient temperature is hotter than the manufacturerrsquos initial rating the duty cycle decreases You need to know what ambient temperature the manufacturer used to rate its PAC in order to operate the equipment at the appropriate duty cycle and prevent damage

212 Rated Cutting Capacity Selection of the PAC is based on the type and thickness of the metal to be cut and the speed at which the metal needs to be cut The higher the PAC ampere and duty cycle rating the thicker and faster it will cut (Figure 7-7) While there is no standard for PAC cutting speeds in the weldingcutting industry some manufacturing companies qualify their PAC rated cutting capacity by three (3) standards (Figure 7-8)

Figure 7-7 mdash Cutting capacity rating

Figure 7-8 mdash Rated cutting capacity

NAVEDTRA 14250A 7-8

bull Rated Cutting Capacity at ten (10) inches per minute travel speed is considered the minimum speed at which an operator achieves a smooth steady cut using a hand-held torch at the machinersquos Rated Output

bull Maximum Quality Cutting Capacity is a good quality cut that is achieved at

slower than ten (10) inches per minute travel speed

bull Sever Cut Capacity is the maximum metal thickness cut achieved in ideal conditions Sever Cut does not include allowances for rating quality of cut or travel speed

213 Cutting Speed As indicated previously the cutting speed will affect the thickness of the material that can be cut The slower you move the torch the thicker the material that can be cut but if you move the torch too slow the plasma arc will remove all of the material directly underneath it and the arc will bend to the side of the kerf causing a jagged cut The faster the travel speeds the thinner the material that can be cut but if you increase the torch speed too much the torch will be unable to cut completely through the workpiece Cutting speed is measured in inches per minute Maximum cutting speed is determined by the arc current nozzle diameter and metal thickness

220 Consumables The plasma torch is designed to generate and focus the plasma cutting arc (Figure 7-9)

In either hand held or machine torches the same parts are used an electrode to carry the current from the power source a swirl ring to spin the compressed air a tip that constricts and focuses the cutting arc and a shield and retaining ring to protect the torch

221 Swirl Ring The swirl ring made of a high temperature plastic is designed with angled holes to spin the cutting gas in a vortex (Figure 7-10) Spinning the gas centers the arc on the electrode and helps control and constrict the arc as it passes through the tip Some plasma cutting equipment swirls the gas in a clockwise direction others in a counter-

Figure 7-10 mdash Swirl ring

Figure 7-9 mdash PAC torch assembly

Figure 7-10 mdash Swirl ring NAVEDTRA 14250A 7-9

clockwise direction Check the manufacturerrsquos manual the direction of flow will indicate which side of the cut will be beveled

222 Electrode The purpose of the electrode is to provide a path for the electricity from the power source and generate the cutting arc (Figure7-11) The electrode is typically made of copper with an insert made of hafnium The hafnium-alloyed electrodes have good wear life when you use clean dry compressed air or nitrogen although electrode consumption may be greater with air plasma than with nitrogen

223 Tip The purpose of the torch tip is to constrict and focus the plasma arc (Figure 7-12) Constricting the arc increases the energy density and velocity The tips are made of copper with a specifically sized hole or orifice in the center of the tip Tips are sized according to the amperage rating of their respective torch

224 Retaining Cup The retaining cup serves two functions (Figure 7-13) First it holds the other consumable parts firmly in place Second it insulates and keeps the other consumable parts from making contact with the work piece

225 Shields There are two types of shields used on plasma torches a drag shield (Figure 7-14) and a deflector (Figure 7-15) The drag shield insulates the front end of the torch from the work piece and protects the torch tip from spatter The deflector insulates the electrode and protects it from spatter It is used when extended cutting consumables are needed

NAVEDTRA 14250A 7-10

226 Consumables Used During Extended Cutting vs Drag Cutting The use of extended cutting consumables requires the operator to maintain a torch standoff of about 18 ldquoTorch stand-offrdquo is the distance from the outer face of the torch tip or constricting orifice nozzle to the base metal surface (Figure 7-16) Extended cutting is used in situations where the operator needs extra control of the cutting arc such as when cutting in a corner or when a machine torch is used The drag shield is constructed so that the required standoff is maintained inside the torch Using drag cutting consumables allows the operator to drag the torch on the work piece while cutting at full output which increases operator comfort and makes template cutting easier Figure 7-16 mdash Extended vs drag

NAVEDTRA 14250A 7-11

227 Consumable Tips for Different Amperages Tip size is directly proportionate to amperage the higher the amperage the larger the tip you would use As you can see in Figure 7-17 the 40-amp tip opening is smaller than the 80-amp tip Exercise caution and be sure to use the correct tip for the amperage If you use an 80-amp tip for a 40-amp machine the plasma arc will not constrict enough and will cut an uneven wide kerf If you use a 40-amp tip on an 80-amp machine internal arcing will damage the tip and electrode decreasing their service life

NAVEDTRA 14250A 7-12

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

Figure 7-19 mdash Consumable inspection process

Figure 7-18 mdash New and worn consumables

NAVEDTRA 14250A 7-13

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

A Excess plasma formation B Resolidified molten metal C Angle on the top of a cut D Preferred shielding material

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

2 What characteristic makes plasma different than a gas

A It has a greater atomic weight B It is incandescent C It can conduct electricity D It has a distinct odor

200 EQUIPMENT and CONSUMABLES A pilot arc between the electrode and the constricting tip initiates the plasma arc process The tip is connected to ground through a current-limiting resistor and a pilot arc relay contact in the torch assembly One of two methods either a high frequency generator connected to the electrode and tip or an internal contact start initiates the pilot arc The welding power supply then maintains a low current arc inside the torch

Ionized orifice gas from the pilot arc is blown through the constricting tip orifice by a compressed gas This forms a low resistance path to ignite the main arc between the electrode and the workpiece (Figure 7-6) When the main arc ignites the pilot arc relay may be opened automatically to avoid unnecessary heating of the constricting tip which helps extend the life of the tip and electrode

210 Equipment Requirements A typical air-cooled PAC system consists of the following components

bull Power source

bull Either a hand-held or a machine-style torch

bull Supply of compressed air or nitrogen

211 Power Source Plasma arc cutting uses a direct current power source The polarity setting for the power source is direct current electrode negative (DCEN) In most systems there is also a positive connection to the torch tip in which the current is limited by a resistor This circuit establishes a pilot arc which then establishes the cutting arc The power source is a constant current power source with a high open circuit voltage (250-400 volts) The amperage is usually adjustable within the range of the power

Figure 7-6 mdash Basic PAC setup

NAVEDTRA 14250A 7-7

source and amperage is directly proportional to the thickness and speed in which the metal can be cut Most manual PAC systems now use switch-mode or inverter technology These sophisticated electronically-controlled or microprocessor-controlled devices are better able to tolerate variations in line voltage take more abuse in the field and deliver better cutting performance while consuming less power with a longer duty cycle The term ldquoduty cyclerdquo identifies the number of minutes out of a 10-minute period that you can operate a plasma cutter at its rated capacity For example a 300-amp welder with a 60 duty could operate at 300 amps for 6 minutes and then needs to cool with its fan running for 4 minutes Manufacturers rate their products based on ambient air temperature so if a cutter is rated at 104ordm F and the ambient temperature where you are working is 84ordm F the duty cycle of the machine increases Conversely if the ambient temperature is hotter than the manufacturerrsquos initial rating the duty cycle decreases You need to know what ambient temperature the manufacturer used to rate its PAC in order to operate the equipment at the appropriate duty cycle and prevent damage

212 Rated Cutting Capacity Selection of the PAC is based on the type and thickness of the metal to be cut and the speed at which the metal needs to be cut The higher the PAC ampere and duty cycle rating the thicker and faster it will cut (Figure 7-7) While there is no standard for PAC cutting speeds in the weldingcutting industry some manufacturing companies qualify their PAC rated cutting capacity by three (3) standards (Figure 7-8)

Figure 7-7 mdash Cutting capacity rating

Figure 7-8 mdash Rated cutting capacity

NAVEDTRA 14250A 7-8

bull Rated Cutting Capacity at ten (10) inches per minute travel speed is considered the minimum speed at which an operator achieves a smooth steady cut using a hand-held torch at the machinersquos Rated Output

bull Maximum Quality Cutting Capacity is a good quality cut that is achieved at

slower than ten (10) inches per minute travel speed

bull Sever Cut Capacity is the maximum metal thickness cut achieved in ideal conditions Sever Cut does not include allowances for rating quality of cut or travel speed

213 Cutting Speed As indicated previously the cutting speed will affect the thickness of the material that can be cut The slower you move the torch the thicker the material that can be cut but if you move the torch too slow the plasma arc will remove all of the material directly underneath it and the arc will bend to the side of the kerf causing a jagged cut The faster the travel speeds the thinner the material that can be cut but if you increase the torch speed too much the torch will be unable to cut completely through the workpiece Cutting speed is measured in inches per minute Maximum cutting speed is determined by the arc current nozzle diameter and metal thickness

220 Consumables The plasma torch is designed to generate and focus the plasma cutting arc (Figure 7-9)

In either hand held or machine torches the same parts are used an electrode to carry the current from the power source a swirl ring to spin the compressed air a tip that constricts and focuses the cutting arc and a shield and retaining ring to protect the torch

221 Swirl Ring The swirl ring made of a high temperature plastic is designed with angled holes to spin the cutting gas in a vortex (Figure 7-10) Spinning the gas centers the arc on the electrode and helps control and constrict the arc as it passes through the tip Some plasma cutting equipment swirls the gas in a clockwise direction others in a counter-

Figure 7-10 mdash Swirl ring

Figure 7-9 mdash PAC torch assembly

Figure 7-10 mdash Swirl ring NAVEDTRA 14250A 7-9

clockwise direction Check the manufacturerrsquos manual the direction of flow will indicate which side of the cut will be beveled

222 Electrode The purpose of the electrode is to provide a path for the electricity from the power source and generate the cutting arc (Figure7-11) The electrode is typically made of copper with an insert made of hafnium The hafnium-alloyed electrodes have good wear life when you use clean dry compressed air or nitrogen although electrode consumption may be greater with air plasma than with nitrogen

223 Tip The purpose of the torch tip is to constrict and focus the plasma arc (Figure 7-12) Constricting the arc increases the energy density and velocity The tips are made of copper with a specifically sized hole or orifice in the center of the tip Tips are sized according to the amperage rating of their respective torch

224 Retaining Cup The retaining cup serves two functions (Figure 7-13) First it holds the other consumable parts firmly in place Second it insulates and keeps the other consumable parts from making contact with the work piece

225 Shields There are two types of shields used on plasma torches a drag shield (Figure 7-14) and a deflector (Figure 7-15) The drag shield insulates the front end of the torch from the work piece and protects the torch tip from spatter The deflector insulates the electrode and protects it from spatter It is used when extended cutting consumables are needed

NAVEDTRA 14250A 7-10

226 Consumables Used During Extended Cutting vs Drag Cutting The use of extended cutting consumables requires the operator to maintain a torch standoff of about 18 ldquoTorch stand-offrdquo is the distance from the outer face of the torch tip or constricting orifice nozzle to the base metal surface (Figure 7-16) Extended cutting is used in situations where the operator needs extra control of the cutting arc such as when cutting in a corner or when a machine torch is used The drag shield is constructed so that the required standoff is maintained inside the torch Using drag cutting consumables allows the operator to drag the torch on the work piece while cutting at full output which increases operator comfort and makes template cutting easier Figure 7-16 mdash Extended vs drag

NAVEDTRA 14250A 7-11

227 Consumable Tips for Different Amperages Tip size is directly proportionate to amperage the higher the amperage the larger the tip you would use As you can see in Figure 7-17 the 40-amp tip opening is smaller than the 80-amp tip Exercise caution and be sure to use the correct tip for the amperage If you use an 80-amp tip for a 40-amp machine the plasma arc will not constrict enough and will cut an uneven wide kerf If you use a 40-amp tip on an 80-amp machine internal arcing will damage the tip and electrode decreasing their service life

Figure 7-17 mdash Consumables chart

NAVEDTRA 14250A 7-12

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

Figure 7-19 mdash Consumable inspection process

Figure 7-18 mdash New and worn consumables

NAVEDTRA 14250A 7-13

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

Figure 7-30 mdash Gouging process

NAVEDTRA 14250A 7-20

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

A Excess plasma formation B Resolidified molten metal C Angle on the top of a cut D Preferred shielding material

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

source and amperage is directly proportional to the thickness and speed in which the metal can be cut Most manual PAC systems now use switch-mode or inverter technology These sophisticated electronically-controlled or microprocessor-controlled devices are better able to tolerate variations in line voltage take more abuse in the field and deliver better cutting performance while consuming less power with a longer duty cycle The term ldquoduty cyclerdquo identifies the number of minutes out of a 10-minute period that you can operate a plasma cutter at its rated capacity For example a 300-amp welder with a 60 duty could operate at 300 amps for 6 minutes and then needs to cool with its fan running for 4 minutes Manufacturers rate their products based on ambient air temperature so if a cutter is rated at 104ordm F and the ambient temperature where you are working is 84ordm F the duty cycle of the machine increases Conversely if the ambient temperature is hotter than the manufacturerrsquos initial rating the duty cycle decreases You need to know what ambient temperature the manufacturer used to rate its PAC in order to operate the equipment at the appropriate duty cycle and prevent damage

212 Rated Cutting Capacity Selection of the PAC is based on the type and thickness of the metal to be cut and the speed at which the metal needs to be cut The higher the PAC ampere and duty cycle rating the thicker and faster it will cut (Figure 7-7) While there is no standard for PAC cutting speeds in the weldingcutting industry some manufacturing companies qualify their PAC rated cutting capacity by three (3) standards (Figure 7-8)

Figure 7-7 mdash Cutting capacity rating

Figure 7-8 mdash Rated cutting capacity

NAVEDTRA 14250A 7-8

bull Rated Cutting Capacity at ten (10) inches per minute travel speed is considered the minimum speed at which an operator achieves a smooth steady cut using a hand-held torch at the machinersquos Rated Output

bull Maximum Quality Cutting Capacity is a good quality cut that is achieved at

slower than ten (10) inches per minute travel speed

bull Sever Cut Capacity is the maximum metal thickness cut achieved in ideal conditions Sever Cut does not include allowances for rating quality of cut or travel speed

213 Cutting Speed As indicated previously the cutting speed will affect the thickness of the material that can be cut The slower you move the torch the thicker the material that can be cut but if you move the torch too slow the plasma arc will remove all of the material directly underneath it and the arc will bend to the side of the kerf causing a jagged cut The faster the travel speeds the thinner the material that can be cut but if you increase the torch speed too much the torch will be unable to cut completely through the workpiece Cutting speed is measured in inches per minute Maximum cutting speed is determined by the arc current nozzle diameter and metal thickness

220 Consumables The plasma torch is designed to generate and focus the plasma cutting arc (Figure 7-9)

In either hand held or machine torches the same parts are used an electrode to carry the current from the power source a swirl ring to spin the compressed air a tip that constricts and focuses the cutting arc and a shield and retaining ring to protect the torch

221 Swirl Ring The swirl ring made of a high temperature plastic is designed with angled holes to spin the cutting gas in a vortex (Figure 7-10) Spinning the gas centers the arc on the electrode and helps control and constrict the arc as it passes through the tip Some plasma cutting equipment swirls the gas in a clockwise direction others in a counter-

Figure 7-10 mdash Swirl ring NAVEDTRA 14250A 7-9

clockwise direction Check the manufacturerrsquos manual the direction of flow will indicate which side of the cut will be beveled

222 Electrode The purpose of the electrode is to provide a path for the electricity from the power source and generate the cutting arc (Figure7-11) The electrode is typically made of copper with an insert made of hafnium The hafnium-alloyed electrodes have good wear life when you use clean dry compressed air or nitrogen although electrode consumption may be greater with air plasma than with nitrogen

223 Tip The purpose of the torch tip is to constrict and focus the plasma arc (Figure 7-12) Constricting the arc increases the energy density and velocity The tips are made of copper with a specifically sized hole or orifice in the center of the tip Tips are sized according to the amperage rating of their respective torch

224 Retaining Cup The retaining cup serves two functions (Figure 7-13) First it holds the other consumable parts firmly in place Second it insulates and keeps the other consumable parts from making contact with the work piece

225 Shields There are two types of shields used on plasma torches a drag shield (Figure 7-14) and a deflector (Figure 7-15) The drag shield insulates the front end of the torch from the work piece and protects the torch tip from spatter The deflector insulates the electrode and protects it from spatter It is used when extended cutting consumables are needed

226 Consumables Used During Extended Cutting vs Drag Cutting The use of extended cutting consumables requires the operator to maintain a torch standoff of about 18 ldquoTorch stand-offrdquo is the distance from the outer face of the torch tip or constricting orifice nozzle to the base metal surface (Figure 7-16) Extended cutting is used in situations where the operator needs extra control of the cutting arc such as when cutting in a corner or when a machine torch is used The drag shield is constructed so that the required standoff is maintained inside the torch Using drag cutting consumables allows the operator to drag the torch on the work piece while cutting at full output which increases operator comfort and makes template cutting easier Figure 7-16 mdash Extended vs drag

NAVEDTRA 14250A 7-11

227 Consumable Tips for Different Amperages Tip size is directly proportionate to amperage the higher the amperage the larger the tip you would use As you can see in Figure 7-17 the 40-amp tip opening is smaller than the 80-amp tip Exercise caution and be sure to use the correct tip for the amperage If you use an 80-amp tip for a 40-amp machine the plasma arc will not constrict enough and will cut an uneven wide kerf If you use a 40-amp tip on an 80-amp machine internal arcing will damage the tip and electrode decreasing their service life

NAVEDTRA 14250A 7-12

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

Figure 7-19 mdash Consumable inspection process

Figure 7-18 mdash New and worn consumables

NAVEDTRA 14250A 7-13

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

Figure 7-30 mdash Gouging process

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

Figure 7-32 mdash Direction of cut Figure 7-31 mdash Elements of a quality cut

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

bull Rated Cutting Capacity at ten (10) inches per minute travel speed is considered the minimum speed at which an operator achieves a smooth steady cut using a hand-held torch at the machinersquos Rated Output

bull Maximum Quality Cutting Capacity is a good quality cut that is achieved at

slower than ten (10) inches per minute travel speed

bull Sever Cut Capacity is the maximum metal thickness cut achieved in ideal conditions Sever Cut does not include allowances for rating quality of cut or travel speed

213 Cutting Speed As indicated previously the cutting speed will affect the thickness of the material that can be cut The slower you move the torch the thicker the material that can be cut but if you move the torch too slow the plasma arc will remove all of the material directly underneath it and the arc will bend to the side of the kerf causing a jagged cut The faster the travel speeds the thinner the material that can be cut but if you increase the torch speed too much the torch will be unable to cut completely through the workpiece Cutting speed is measured in inches per minute Maximum cutting speed is determined by the arc current nozzle diameter and metal thickness

220 Consumables The plasma torch is designed to generate and focus the plasma cutting arc (Figure 7-9)

In either hand held or machine torches the same parts are used an electrode to carry the current from the power source a swirl ring to spin the compressed air a tip that constricts and focuses the cutting arc and a shield and retaining ring to protect the torch

221 Swirl Ring The swirl ring made of a high temperature plastic is designed with angled holes to spin the cutting gas in a vortex (Figure 7-10) Spinning the gas centers the arc on the electrode and helps control and constrict the arc as it passes through the tip Some plasma cutting equipment swirls the gas in a clockwise direction others in a counter-

Figure 7-10 mdash Swirl ring NAVEDTRA 14250A 7-9

clockwise direction Check the manufacturerrsquos manual the direction of flow will indicate which side of the cut will be beveled

222 Electrode The purpose of the electrode is to provide a path for the electricity from the power source and generate the cutting arc (Figure7-11) The electrode is typically made of copper with an insert made of hafnium The hafnium-alloyed electrodes have good wear life when you use clean dry compressed air or nitrogen although electrode consumption may be greater with air plasma than with nitrogen

223 Tip The purpose of the torch tip is to constrict and focus the plasma arc (Figure 7-12) Constricting the arc increases the energy density and velocity The tips are made of copper with a specifically sized hole or orifice in the center of the tip Tips are sized according to the amperage rating of their respective torch

224 Retaining Cup The retaining cup serves two functions (Figure 7-13) First it holds the other consumable parts firmly in place Second it insulates and keeps the other consumable parts from making contact with the work piece

225 Shields There are two types of shields used on plasma torches a drag shield (Figure 7-14) and a deflector (Figure 7-15) The drag shield insulates the front end of the torch from the work piece and protects the torch tip from spatter The deflector insulates the electrode and protects it from spatter It is used when extended cutting consumables are needed

226 Consumables Used During Extended Cutting vs Drag Cutting The use of extended cutting consumables requires the operator to maintain a torch standoff of about 18 ldquoTorch stand-offrdquo is the distance from the outer face of the torch tip or constricting orifice nozzle to the base metal surface (Figure 7-16) Extended cutting is used in situations where the operator needs extra control of the cutting arc such as when cutting in a corner or when a machine torch is used The drag shield is constructed so that the required standoff is maintained inside the torch Using drag cutting consumables allows the operator to drag the torch on the work piece while cutting at full output which increases operator comfort and makes template cutting easier Figure 7-16 mdash Extended vs drag

NAVEDTRA 14250A 7-11

227 Consumable Tips for Different Amperages Tip size is directly proportionate to amperage the higher the amperage the larger the tip you would use As you can see in Figure 7-17 the 40-amp tip opening is smaller than the 80-amp tip Exercise caution and be sure to use the correct tip for the amperage If you use an 80-amp tip for a 40-amp machine the plasma arc will not constrict enough and will cut an uneven wide kerf If you use a 40-amp tip on an 80-amp machine internal arcing will damage the tip and electrode decreasing their service life

NAVEDTRA 14250A 7-12

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

NAVEDTRA 14250A 7-13

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

Figure 7-30 mdash Gouging process

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

Figure 7-32 mdash Direction of cut Figure 7-31 mdash Elements of a quality cut

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

clockwise direction Check the manufacturerrsquos manual the direction of flow will indicate which side of the cut will be beveled

222 Electrode The purpose of the electrode is to provide a path for the electricity from the power source and generate the cutting arc (Figure7-11) The electrode is typically made of copper with an insert made of hafnium The hafnium-alloyed electrodes have good wear life when you use clean dry compressed air or nitrogen although electrode consumption may be greater with air plasma than with nitrogen

223 Tip The purpose of the torch tip is to constrict and focus the plasma arc (Figure 7-12) Constricting the arc increases the energy density and velocity The tips are made of copper with a specifically sized hole or orifice in the center of the tip Tips are sized according to the amperage rating of their respective torch

224 Retaining Cup The retaining cup serves two functions (Figure 7-13) First it holds the other consumable parts firmly in place Second it insulates and keeps the other consumable parts from making contact with the work piece

225 Shields There are two types of shields used on plasma torches a drag shield (Figure 7-14) and a deflector (Figure 7-15) The drag shield insulates the front end of the torch from the work piece and protects the torch tip from spatter The deflector insulates the electrode and protects it from spatter It is used when extended cutting consumables are needed

226 Consumables Used During Extended Cutting vs Drag Cutting The use of extended cutting consumables requires the operator to maintain a torch standoff of about 18 ldquoTorch stand-offrdquo is the distance from the outer face of the torch tip or constricting orifice nozzle to the base metal surface (Figure 7-16) Extended cutting is used in situations where the operator needs extra control of the cutting arc such as when cutting in a corner or when a machine torch is used The drag shield is constructed so that the required standoff is maintained inside the torch Using drag cutting consumables allows the operator to drag the torch on the work piece while cutting at full output which increases operator comfort and makes template cutting easier Figure 7-16 mdash Extended vs drag

NAVEDTRA 14250A 7-11

227 Consumable Tips for Different Amperages Tip size is directly proportionate to amperage the higher the amperage the larger the tip you would use As you can see in Figure 7-17 the 40-amp tip opening is smaller than the 80-amp tip Exercise caution and be sure to use the correct tip for the amperage If you use an 80-amp tip for a 40-amp machine the plasma arc will not constrict enough and will cut an uneven wide kerf If you use a 40-amp tip on an 80-amp machine internal arcing will damage the tip and electrode decreasing their service life

NAVEDTRA 14250A 7-12

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

Figure 7-29 mdash Gouging tips

Figure 7-27 mdash Pierce cut

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

Figure 7-30 mdash Gouging process

NAVEDTRA 14250A 7-20

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

Figure 7-32 mdash Direction of cut Figure 7-31 mdash Elements of a quality cut

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

Summary This chapter introduced you to the basics of plasma arc cutting a very easy method of cutting all conductive metals which requires very little training to use It discussed the formation of plasma and its properties explained the equipment used for plasma arc cutting and gave some proper cutting techniques It also presented some advantages and disadvantages of plasma arc cutting over other cutting methods The main theme of the chapter was to select the right size PAC for the job at hand based on the type and thickness of the metal to be cut while keeping a constant eye on the torch consumables to ensure proper production efficiency is maintained Finally it cannot be overemphasized to follow all of the manufacturerrsquos recommended operating and safety procedures

226 Consumables Used During Extended Cutting vs Drag Cutting The use of extended cutting consumables requires the operator to maintain a torch standoff of about 18 ldquoTorch stand-offrdquo is the distance from the outer face of the torch tip or constricting orifice nozzle to the base metal surface (Figure 7-16) Extended cutting is used in situations where the operator needs extra control of the cutting arc such as when cutting in a corner or when a machine torch is used The drag shield is constructed so that the required standoff is maintained inside the torch Using drag cutting consumables allows the operator to drag the torch on the work piece while cutting at full output which increases operator comfort and makes template cutting easier Figure 7-16 mdash Extended vs drag

NAVEDTRA 14250A 7-11

227 Consumable Tips for Different Amperages Tip size is directly proportionate to amperage the higher the amperage the larger the tip you would use As you can see in Figure 7-17 the 40-amp tip opening is smaller than the 80-amp tip Exercise caution and be sure to use the correct tip for the amperage If you use an 80-amp tip for a 40-amp machine the plasma arc will not constrict enough and will cut an uneven wide kerf If you use a 40-amp tip on an 80-amp machine internal arcing will damage the tip and electrode decreasing their service life

NAVEDTRA 14250A 7-12

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

NAVEDTRA 14250A 7-13

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

Figure 7-27 mdash Pierce cut

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

Figure 7-30 mdash Gouging process

NAVEDTRA 14250A 7-20

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

Figure 7-32 mdash Direction of cut Figure 7-31 mdash Elements of a quality cut

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

Summary This chapter introduced you to the basics of plasma arc cutting a very easy method of cutting all conductive metals which requires very little training to use It discussed the formation of plasma and its properties explained the equipment used for plasma arc cutting and gave some proper cutting techniques It also presented some advantages and disadvantages of plasma arc cutting over other cutting methods The main theme of the chapter was to select the right size PAC for the job at hand based on the type and thickness of the metal to be cut while keeping a constant eye on the torch consumables to ensure proper production efficiency is maintained Finally it cannot be overemphasized to follow all of the manufacturerrsquos recommended operating and safety procedures

227 Consumable Tips for Different Amperages Tip size is directly proportionate to amperage the higher the amperage the larger the tip you would use As you can see in Figure 7-17 the 40-amp tip opening is smaller than the 80-amp tip Exercise caution and be sure to use the correct tip for the amperage If you use an 80-amp tip for a 40-amp machine the plasma arc will not constrict enough and will cut an uneven wide kerf If you use a 40-amp tip on an 80-amp machine internal arcing will damage the tip and electrode decreasing their service life

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

Figure 7-27 mdash Pierce cut

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

Figure 7-30 mdash Gouging process

NAVEDTRA 14250A 7-20

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

Figure 7-32 mdash Direction of cut Figure 7-31 mdash Elements of a quality cut

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

Summary This chapter introduced you to the basics of plasma arc cutting a very easy method of cutting all conductive metals which requires very little training to use It discussed the formation of plasma and its properties explained the equipment used for plasma arc cutting and gave some proper cutting techniques It also presented some advantages and disadvantages of plasma arc cutting over other cutting methods The main theme of the chapter was to select the right size PAC for the job at hand based on the type and thickness of the metal to be cut while keeping a constant eye on the torch consumables to ensure proper production efficiency is maintained Finally it cannot be overemphasized to follow all of the manufacturerrsquos recommended operating and safety procedures

228 Replacing Consumables Good preventive maintenance (PM) requires keeping a supply of electrodes tips and shield cups on hand and replacing them as wear appears You should inspect the shield cup tip and electrode before each use hourly during operation or whenever the cutting speed has reduced significantly Do not operate the PAC torch without a tip or an electrode in place A tip and electrode that are worn beyond the manufacturerrsquos recommended values or operating a torch without the tip or electrode in place can damage the torch Refer to Figure 7-18 for a comparison of new and worn consumables Figure 7-19 shows what to look for in the inspection process

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

Figure 7-32 mdash Direction of cut Figure 7-31 mdash Elements of a quality cut

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

Summary This chapter introduced you to the basics of plasma arc cutting a very easy method of cutting all conductive metals which requires very little training to use It discussed the formation of plasma and its properties explained the equipment used for plasma arc cutting and gave some proper cutting techniques It also presented some advantages and disadvantages of plasma arc cutting over other cutting methods The main theme of the chapter was to select the right size PAC for the job at hand based on the type and thickness of the metal to be cut while keeping a constant eye on the torch consumables to ensure proper production efficiency is maintained Finally it cannot be overemphasized to follow all of the manufacturerrsquos recommended operating and safety procedures

229 Cutting Gases Plasma arc cutting gases must have high ionization potential (energy) high thermal conductivity to deliver high heat energy to the work piece and high atomic weight to produce the energy to blow or push out metal from the cut Compressed air (approximately 80 nitrogen) with its high ionization potential and density is commonly used to minimize gas costs Compressed air may require installation of filters or line dryers to remove oil vapors and moisture Clean dry compressed air may be purchased in cylinders As a plasma gas nitrogen is considered to be the gas that creates the least slag or dross The gas pressure and flow rates must be properly set to the equipment manufacturerrsquos recommendation The gas supply piping and hoses to the cutting unit must be of sufficient size to carry the pressure and gas volume required Use a minimum 38 ID (inside diameter) piping or nonconductive hoses to provide the necessary pressure and volume of gas to the PAC power source If the piping or hose is more than 40 feet in length use a minimum 12 ID (Figure 7-20)

230 Improving Consumable life 1 Maintain proper gas pressure setting Setting the correct amount of gas pressure is very important to consumable life If the pressure setting is too high electrode life will be shortened If the pressure setting is too low the tip life will be shortened 2 Maintain the correct stand off If extended cutting consumables are being used make sure to maintain the recommended amount of standoff Too little standoff may damage the torch and consumables Too much standoff will result in inconsistent arc starts 3 Pierce within the limits of the plasma system Do not try to pierce metals that are too thick for the plasma cutter The typical rating is to pierce up to half the rated cutting thickness of the plasma cutter For example if the plasma cutter is rated to cut 1 steel it could pierce 12 steel

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

Figure 7-32 mdash Direction of cut Figure 7-31 mdash Elements of a quality cut

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

4 Make sure the gas used is clean and dry Plasma cutting systems require clean dry gas to operate properly Moisture in the gas line is the cause of many system problems It can cause shortened consumable life and premature torch failure To check for moisture in the gas line set the system to the gasair set position and hold a mirror under the tip (Figure 7-21) If any moisture appears on the mirror inspect the system for the source of the moisture or install an air dryer in the system 5 Use edge starts Use edge starts whenever possible instead of pierce starts Edge starts improve consumable life since there is less chance for molten metal to be blown back into the tip 6 Use the tip saver setting Whenever possible use the tip saver position for the pilot arc More pilot arc time than is necessary will lead to shorter consumable life Use the expanded metal setting only when absolutely necessary 7 Remove buildup from shields Inspect the shields on the end of the torch frequently and remove any slag from the shield Slag can cause double arcing which shortens tip life 8 Purge gas after changing consumables Purge gas lines for 2ndash3 minutes after changing consumables or extended periods of little or no use This will ensure that any moisture built up in the lines is removed 9 Keep torch and consumables clean Any type of contamination in the torch or consumables can affect the performance of the cutting system When you change consumables always try to keep the new parts on a clean rag

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

Figure 7-32 mdash Direction of cut Figure 7-31 mdash Elements of a quality cut

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

Trade Terms Introduced in this Chapter Dross The oxidized material that melts during cutting and adheres

to the workpiece

Hafnium A grey metallic element that resembles zirconium chemically and is found in zirconium minerals used in filaments for its ready emission of electrons

Kerf The groove or cut made by the cutting torch

Ionized A gas is acted upon by the intense heat of plasma causing a net electric charge by adding or removing one or more electrons

Oxidation The deposit that forms on the surface of a metal as it oxidizes This deposit increases the melting temperature of the metal causing uneven flow of welding material and therefore a bad weld

Plenum The state or space in which a gas usually air is contained at a pressure greater than atmospheric pressure

300 CUTTING and GOUGING OPERATING SEQUENCE The first step in operating a PAC system is to perform a system check Make sure that the torch is assembled properly Turn the power source and air supply on Next check the status lights on the power source The status lights advise the operator if the system is ready to cut or if there is a problem that will keep the unit from operating properly There may be two to four status lights depending on the model of the power source (Figure 7-22) Typically the top light is labeled ldquopowerrdquo When this light is on it indicates the power source is on If the power light is the only light on that indicates that the system is ready to cut If an additional light is on that is the indication of a problem in the system Three parts of the system are monitored and when not functioning properly cause the additional status light to turn on and keep the system from cutting These parts are the torch assembly the air pressure setting and the internal temperature of the power supply Should an additional status light come on check to make sure the torch is properly assembled the air pressure is set to the recommended setting and it has had a chance to cool if the power source has been cutting continuously for more than the rated duty cycle time period Once these problems have been fixed the status light will turn off and the system will be ready to cut After verifying that the status lights indicate that the system is ready to cut purge the gas lines for a minute to get rid of any moisture that may have formed inside the lines When the trigger has energized the circuit a preflow of gas will flow through the torch for a few seconds This is done to ensure that the right amount of gas flow is available before an arc is created The cutting arc is created by one of two different starting methods high frequency starts or contact starts

310 High Frequency Starts The tried-and-true method is a high-frequency (HF) starting circuit built into the power supply This system uses a high-voltage transformer (similar to a bug zapper) capacitors and a spark-gap assembly to generate a high-voltage spark at the torch (Figure 7-23) The spark ionizes the plasma gas enabling current to flow across the air gap Figure 7-23 mdash HF starting circuit

Figure 7-22 mdash Control panel

NAVEDTRA 14250A 7-16

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

Figure 7-27 mdash Pierce cut

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

Trade Terms Introduced in this Chapter Dross The oxidized material that melts during cutting and adheres

to the workpiece

Hafnium A grey metallic element that resembles zirconium chemically and is found in zirconium minerals used in filaments for its ready emission of electrons

Kerf The groove or cut made by the cutting torch

Ionized A gas is acted upon by the intense heat of plasma causing a net electric charge by adding or removing one or more electrons

Oxidation The deposit that forms on the surface of a metal as it oxidizes This deposit increases the melting temperature of the metal causing uneven flow of welding material and therefore a bad weld

Plenum The state or space in which a gas usually air is contained at a pressure greater than atmospheric pressure

between the nozzle and electrode The resulting arc is called the pilot arc High-frequency starting systems are simple relatively dependable and require no moving parts in the torch However they do need periodic maintenance to prevent hard-starting problems Another potential problem is the high frequency that radiates from the system creating electrical noise that may interfere with sensitive electronic equipment

320 Contact Starts A contact start torch uses a moving electrode or nozzle to create the initial spark that enables the pilot arc (Figure 7-24) When the torch is fired the electrode and nozzle are in contact in a dead short or short circuit When the operator depresses the trigger gas enters the plasma chamber it blows the electrode back (or the nozzle forward) creating a spark This process is similar to the spark created when an electrical plug is pulled quickly from a receptacle After the initial arc is created the gas flow pushes the arc through the orifice and reestablishes it on the outside of the tip This forms a J-shaped arc called the pilot arc The pilot arc forms a path to the metal surface to be cut When the torch is close enough to the metal the arc will transfer from a pilot arc between the electrode and the tip to a cutting arc between the electrode and the workpiece Contact start torches produce much less electrical noise than HF systems and they are instant-on torches which reduces cycle time because of the lack of preflow

330 Pilot Arc Control Methods On some power sources the pilot arc remains on even after the cutting arc is established An advantage to this is that if the operator is cutting over a piece of expanded metal for example the cutting arc is maintained as the arc moves from one piece of metal to the other One disadvantage of leaving the pilot arc on at all times during the cutting process is that it can lead to faster consumable wear To help address these issues some power sources have ways of controlling the pilot arc so that it is on when needed and can be shut off when not needed In some cases the power source has a switch that gives the operator a choice of settings for the pilot arc The operator can select the expanded metal position for a continuous pilot arc or the tip saver position where the pilot arc shuts off after the cutting arc is established

Figure 7-24 mdash Contact start

NAVEDTRA 14250A 7-17

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Figure 7-25 mdash Starting an edge cut

Figure 7-26 mdash Edge cut process

NAVEDTRA 14250A 7-18

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

Figure 7-27 mdash Pierce cut

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

Figure 7-32 mdash Direction of cut Figure 7-31 mdash Elements of a quality cut

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

Trade Terms Introduced in this Chapter Dross The oxidized material that melts during cutting and adheres

to the workpiece

Hafnium A grey metallic element that resembles zirconium chemically and is found in zirconium minerals used in filaments for its ready emission of electrons

Kerf The groove or cut made by the cutting torch

Ionized A gas is acted upon by the intense heat of plasma causing a net electric charge by adding or removing one or more electrons

Oxidation The deposit that forms on the surface of a metal as it oxidizes This deposit increases the melting temperature of the metal causing uneven flow of welding material and therefore a bad weld

Plenum The state or space in which a gas usually air is contained at a pressure greater than atmospheric pressure

Other power sources are equipped with a circuit that automatically controls the pilot arc The pilot arc will switch in and out as fast as needed when cutting expanded metal or multiple pieces of metal When cutting on a solid piece of metal the pilot arc will drop out after the cutting arc has been established

340 Starting the Cut With a hand-held torch there are two methods for starting the cut edge starts and pierce starts To use an edge start place the torch directly over the edge of the work piece (Figure 7-25) With the tip centered on the edge of the metal start the arc and begin moving the torch along the cut line (Figure 7-26)

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

Pierce cuts are a little more difficult The torch will need to be angled slightly over the starting point (Figure 7-27)This will prevent the molten metal from the beginning of the cut from being blown back into the tip and electrode Once the cutting arc has pierced through the metal move the torch to a vertical position and continue along the cut line The thicker the metal the longer it will take the cutting arc to pierce through the metal The process of piercing a hole in the metal will cause a blow hole that is wider than the normal kerf so the initial pierce should be done in the scrap portion of the part not on the cut line (Figure 7-28)

400 PLASMA ARC GOUGING Plasma Arc Gouging is a variation or an adaptation of the PAC process Gouging utilizes a different torch tip that produces a reduction in the arc constriction which results in a lower arc stream velocity Note the larger diameter orifice of the gouging tip (Figure 7-29) This larger diameter orifice provides the reduction in arc constriction which results in a lower arc stream velocity It gives a softer wider arc and proper stream velocity Gouging may be used for edge preparation (J or U-grooves) removal of welds or discontinuities in welds and it may be used in all positions

Figure 7-27 mdash Pierce cut

NAVEDTRA 14250A 7-19

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

When comparing PAC with Air Carbon Arc Gouging (CAC-A) one major difference is that with PAC the gouge surface is bright and clean This is particularly true with the aluminum alloys and stainless steels There is virtually no cleanup required because the gouges are clean and absent of carbon contamination as is the case when using the CAC-A process Because of this CAC-A is not recommended as a weld preparation for stainless steel and aluminum without subsequent and sufficient cleaning The technique for plasma arc gouging requires the torch be angled 30deg to 45deg from the base metal surface This torch angle and the speed of travel will determine the gouging depth It is important that not too much material be removed in a single pass It is better to remove by gouging to the required depth and width by using multiple passes (Figure 7-30)

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

A Excess plasma formation B Resolidified molten metal C Angle on the top of a cut D Preferred shielding material

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

500 QUALITIES of a PLASMA CUT Good quality cuts result in less time and effort being spent on cleaning up the part before it goes to the next step in the manufacturing process If the part is to be welded a clean cut is important in order to produce a good weld It takes several terms to define a quality cut (Figures 7-31and 7-32)

510 Kerf The kerf is the width of the cut or the amount of metal removed by the cutting process All cutting processes produce a kerf You must account for the kerf when cutting to specific dimensions or determining the number of parts that can be cut from a piece Factors that affect the size of the kerf include cutting speed amperage setting amount of standoff and the size of the orifice in the tip

520 Bevel Angle As the plasma gas cuts through the metal it has a swirling motion As a result of this motion the arc has more energy on one side of the cut than the other This leads to a cut that is straight on one side and has a bevel angle (typically four to six degrees) on the other side The direction of travel and the swirl of the gas determine which side will be straight and which side will be beveled On a torch with a clockwise swirl (this includes all Miller torches) the straight side of the cut will be the right side of the cut in the direction of travel Being aware of this characteristic of plasma cutting will ensure that the part being produced has straight edges while the scrap piece has the beveled edge

530 Drag Line Drag lines are ripples along the surface of the cut The travel speed and amperage setting will have the most effect on the appearance of the drag lines

Figure 7-32 mdash Direction of cut Figure 7-31 mdash Elements of a quality cut

NAVEDTRA 14250A 7-21

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

Test your Knowledge (Select the Correct Response)5 What is dross

A Excess plasma formation B Resolidified molten metal C Angle on the top of a cut D Preferred shielding material

6 What is the most likely reason the plasma torch would not cut through the work piece A Incorrect angle B Wrong shielding gas C Rapid torch speed D Inexperienced technician

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

540 Top Rounding Top edge rounding is a slight rounding over of the metal at the top of the cut It is caused by the fact that the arc is hotter at the top of the cut than at the bottom There is usually some top edge rounding in any plasma cut part It is most affected by material thickness and is more apparent on thicker metals

550 Dross Dross is re-solidified oxidized molten metal that is not fully ejected from the kerf during cutting It is the most common cut quality problem of plasma cutting Dross may form as a thick bubbly accumulation along the bottom edge of the plate a small hard bead of uncut material (high-speed dross) or a light coating along the top surface of the plate (top spatter) Dross is affected by the materialrsquos variables such as thickness and type grade chemical composition surface condition flatness and even temperature changes as the material is cut However the three most critical variables to consider in dross formation are cutting speed amperage and standoff distance If the cutting speed is too slow the plasma jet begins to look for more material to cut The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer ejects the molten material from the cut As a result this molten material begins to accumulate along the bottom edge of the plate in a thick globular form This is called low-speed dross At extremely low speeds the arc extinguishes because there is not enough metal to sustain a transferred arc Increasing the amperage or decreasing the standoff (while keeping material thickness and speed constant) have a similar effect on the cut as slowing down the cut speed Both of these changes cause more energy from the plasma jet to contact a given area of the material in a given period of time Excessive amperage or low standoff can also cause low-speed dross Some low speed dross in the corners of a plasma cut is normal since velocity does not remain constant through a sharp turn To prevent low-speed dross form forming increase the cut speed in 5 ipm increments increase the standoff in 116-inch increments or 5 volt increments or decrease the amperage in 10 amp increments If none of these measures improves the cut consider a smaller nozzle size If the cutting speed is too fast the arc begins to lag back in the kerf leaving a small hard bead of uncut material or rollover dross along the bottom of the plate This high-speed dross is more tenacious and usually requires extensive machining to remove At extremely high speeds the arc becomes unstable and begins oscillating up and down in the kerf causing a rooster tail of sparks and molten material At these speeds the arc may fail to penetrate the metal or may extinguish High standoff or low amperage (for a given material thickness and cutting speed) can also cause high-speed dross since both of these changes cause a reduction in the energy of the plasma jet To prevent high speed dross first check the nozzle for signs of wear (gouging oversize or elliptical orifice) decrease the cutting speed in 5 ipm increments decrease the standoff in 116-inch increments or 5 volts increments or increase the amperage (do not exceed 95 of the nozzle orifice rating) Top spatter is an accumulation of re-solidified metal that sprays along the top of the cut piece It is usually very easy to remove The usual cause is a worn nozzle excessive cutting speed a high standoff or the swirling flow of the plasma jet which at a certain angle of attack flings molten material out in front of the kerf rather than down through it NAVEDTRA 14250A 7-22

To eliminate top spatter check the nozzle for signs of wear decrease the cutting speed in 5 ipm increments or decrease the standoff in 116-inch increments or 5 volt increments

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

Summary This chapter introduced you to the basics of plasma arc cutting a very easy method of cutting all conductive metals which requires very little training to use It discussed the formation of plasma and its properties explained the equipment used for plasma arc cutting and gave some proper cutting techniques It also presented some advantages and disadvantages of plasma arc cutting over other cutting methods The main theme of the chapter was to select the right size PAC for the job at hand based on the type and thickness of the metal to be cut while keeping a constant eye on the torch consumables to ensure proper production efficiency is maintained Finally it cannot be overemphasized to follow all of the manufacturerrsquos recommended operating and safety procedures

6 What is the most likely reason the plasma torch would not cut through the work piece A Incorrect angle B Wrong shielding gas C Rapid torch speed D Inexperienced technician

560 Six Steps to Good Cut Quality 1 Use quality consumable parts You will not get quality cuts without quality parts Use the parts recommended by the manufacturer These parts are made to the exact tolerances required to ensure quality cuts To further ensure quality cuts always start with a new set of consumables 2 Assemble the torch properly Assemble the torch carefully making sure the parts are properly aligned and fit together snugly This will ensure good electrical contact and cutting performance Keep parts in their storage containers until needed in order to prevent contamination from dirt and dust 3 Set the amperage no higher than necessary The amperage should be set based on the metal thickness being cut Using more amperage than needed will shorten consumable life 4 Square the torch with the part to be cut If the torch is not aligned perpendicular with the part the cut may form a beveled edge instead of a straight edge Check the squareness of the torch visually before starting to cut 5 Verify the direction of travel Depending on the manufacturer and the direction of the air flow the square side of the cut may be the right-hand side in the direction of travel Perform a test cut to verify the location of the square edge 6 Adjust the travel speed During the test cut determine the travel speed that will provide either a dross-free or minimal-dross cut Increasing travel speed will also insure that you do not have a negative bevel angle

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

600 SAFETY PROCEDURES As it is with any cutting or welding process safety is the prime consideration The equipment ownerrsquos manuals will provide safety recommendations that must be followed The plasma arc emits intense visible and invisible radiation (ultraviolet and infrared) Operators need to be fully clothed with dark leather or woolen clothing Ultraviolet radiation can cause rapid disintegration of cotton-based clothing Dark clothing reduces reflection particularly underneath the welding helmet where reflected ultraviolet burns can occur to the face and neck To provide adequate protection for the eyes use filter lenses conforming to ANSI Z491 (Table 7-1)

When cutting thicker materials it may be necessary to wear ear protection Also water tables are sometimes used beneath cutting tables If a water table is used strict guidelines must be followed to avoid such problems as hydrogen gas buildup beneath the plate being cut This is especially the case when cutting aluminum and also when argonhydrogen mixtures are used as the cutting gas The PAC process produces fumes and gases that can harm your health The composition and rate of generation of fumes and gases depend on many factors including arc current cutting speed material being cut and gases used The fume and gas by-products will usually consist of the oxides of the metal being cut ozone oxides of nitrogen and phosgene gas Adequate ventilation is required during the plasma arc cutting process due to the brightness of the plasma arc which causes air to break down into ozone These fumes must be removed from the work area or eliminated at the source by an appropriate exhaust system Take the proper precautions to avoid being burned by hot molten material sparks can travel in excess of 35 feet during the cutting process Do not wear any clothing with cuffs or uncovered pockets and always wear the proper insulated gloves Handle compressed gas cylinders carefully Secure them when stored or in use knocks falls or rough handling can damage cylinders and valves causing leakage and potential accidents

NAVEDTRA 14250A 7-24

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

Summary This chapter introduced you to the basics of plasma arc cutting a very easy method of cutting all conductive metals which requires very little training to use It discussed the formation of plasma and its properties explained the equipment used for plasma arc cutting and gave some proper cutting techniques It also presented some advantages and disadvantages of plasma arc cutting over other cutting methods The main theme of the chapter was to select the right size PAC for the job at hand based on the type and thickness of the metal to be cut while keeping a constant eye on the torch consumables to ensure proper production efficiency is maintained Finally it cannot be overemphasized to follow all of the manufacturerrsquos recommended operating and safety procedures

Use the following guidance when setting up and using cylinders of gas 1 Properly secure the cylinder 2 Before connecting a regulator purge the valve of dust and debris 3 When you attach a regulator to a cylinder be sure it is in a fully closed condition

Once you have opened the cylinder valve slowly adjust the screw on the regulator slowly until you obtain the correct pressure

4 When the cylinder is not in use close the valve and the regulator Operators and maintenance people should keep in mind that PAC equipment operates with a higher output voltage than typical welding equipment Always follow recommended safety procedures as outlined by the equipment manufacturer Read Material Safety Data Sheets (MSDSs) for metals consumables and coatings Further information on safety can be found in the American Welding Society publications ldquoSafety in Welding and Cutting ANSI ASC Z491rdquo

Summary This chapter introduced you to the basics of plasma arc cutting a very easy method of cutting all conductive metals which requires very little training to use It discussed the formation of plasma and its properties explained the equipment used for plasma arc cutting and gave some proper cutting techniques It also presented some advantages and disadvantages of plasma arc cutting over other cutting methods The main theme of the chapter was to select the right size PAC for the job at hand based on the type and thickness of the metal to be cut while keeping a constant eye on the torch consumables to ensure proper production efficiency is maintained Finally it cannot be overemphasized to follow all of the manufacturerrsquos recommended operating and safety procedures

Trade Terms Introduced in this Chapter Dross The oxidized material that melts during cutting and adheres

to the workpiece

Hafnium A grey metallic element that resembles zirconium chemically and is found in zirconium minerals used in filaments for its ready emission of electrons

Kerf The groove or cut made by the cutting torch

Ionized A gas is acted upon by the intense heat of plasma causing a net electric charge by adding or removing one or more electrons

Oxidation The deposit that forms on the surface of a metal as it oxidizes This deposit increases the melting temperature of the metal causing uneven flow of welding material and therefore a bad weld

Plenum The state or space in which a gas usually air is contained at a pressure greater than atmospheric pressure

Trade Terms Introduced in this Chapter Dross The oxidized material that melts during cutting and adheres

to the workpiece

Hafnium A grey metallic element that resembles zirconium chemically and is found in zirconium minerals used in filaments for its ready emission of electrons

Kerf The groove or cut made by the cutting torch

Ionized A gas is acted upon by the intense heat of plasma causing a net electric charge by adding or removing one or more electrons

Oxidation The deposit that forms on the surface of a metal as it oxidizes This deposit increases the melting temperature of the metal causing uneven flow of welding material and therefore a bad weld

Plenum The state or space in which a gas usually air is contained at a pressure greater than atmospheric pressure

Trade Terms Introduced in this Chapter Dross The oxidized material that melts during cutting and adheres

to the workpiece

Hafnium A grey metallic element that resembles zirconium chemically and is found in zirconium minerals used in filaments for its ready emission of electrons

Kerf The groove or cut made by the cutting torch

Ionized A gas is acted upon by the intense heat of plasma causing a net electric charge by adding or removing one or more electrons

Oxidation The deposit that forms on the surface of a metal as it oxidizes This deposit increases the melting temperature of the metal causing uneven flow of welding material and therefore a bad weld

Plenum The state or space in which a gas usually air is contained at a pressure greater than atmospheric pressure

Trade Terms Introduced in this Chapter Dross The oxidized material that melts during cutting and adheres

to the workpiece

Hafnium A grey metallic element that resembles zirconium chemically and is found in zirconium minerals used in filaments for its ready emission of electrons

Kerf The groove or cut made by the cutting torch

Ionized A gas is acted upon by the intense heat of plasma causing a net electric charge by adding or removing one or more electrons

Oxidation The deposit that forms on the surface of a metal as it oxidizes This deposit increases the melting temperature of the metal causing uneven flow of welding material and therefore a bad weld

Plenum The state or space in which a gas usually air is contained at a pressure greater than atmospheric pressure

Trade Terms Introduced in this Chapter Dross The oxidized material that melts during cutting and adheres

to the workpiece

Hafnium A grey metallic element that resembles zirconium chemically and is found in zirconium minerals used in filaments for its ready emission of electrons

Kerf The groove or cut made by the cutting torch

Ionized A gas is acted upon by the intense heat of plasma causing a net electric charge by adding or removing one or more electrons

Oxidation The deposit that forms on the surface of a metal as it oxidizes This deposit increases the melting temperature of the metal causing uneven flow of welding material and therefore a bad weld

Plenum The state or space in which a gas usually air is contained at a pressure greater than atmospheric pressure

Trade Terms Introduced in this Chapter Dross The oxidized material that melts during cutting and adheres

to the workpiece

Hafnium A grey metallic element that resembles zirconium chemically and is found in zirconium minerals used in filaments for its ready emission of electrons

Kerf The groove or cut made by the cutting torch

Ionized A gas is acted upon by the intense heat of plasma causing a net electric charge by adding or removing one or more electrons

Oxidation The deposit that forms on the surface of a metal as it oxidizes This deposit increases the melting temperature of the metal causing uneven flow of welding material and therefore a bad weld

Plenum The state or space in which a gas usually air is contained at a pressure greater than atmospheric pressure
