1.0 GENERAL INFORMATION 1.01 Notes, Cautions and Warnings Throughout this manual, notes, cautions, and warnings are used to highlight important information. These highlights are categorized as follows: NOTE An operation, procedure, or background information which requires additional emphasis or is helpful in efficient operation of the system.

CAUTION A procedure which, if not properly followed, may cause damage to the equipment.

WARNING A procedure which, if not properly followed, may cause injury to the operator or others in the operating area. 1.02 Important Safety Precautions

WARNING OPERATION AND MAINTENANCE OF ARC WELDING EQUIPMENT CAN BE DANGEROUS AND HAZARDOUS TO YOUR HEALTH. To prevent possible injury, read, understand and follow all warnings, safety precautions and instructions before using the equipment. Call 86-21-69171135 or your local distributor if you have any questions.

GASES AND FUMES Gases and fumes produced during the Arc welding or cutting process can be dangerous and hazardous to your health.

Keep all fumes and gases from the breathing area. Keep your head out of the welding fume plume. Use an air-supplied respirator if ventilation is not adequate to remove all fumes and gases. The kinds of fumes and gases from the arc welding/cutting depend on the kind of metal being used,

coatings on the metal, and the different processes. You must be very careful when cutting or welding any metals which may contain one or more of the following: Antimony Arsenic Barium Beryllium Cadmium Chromium Cobalt Copper Lead Manganese Mercury Nickel Selenium Silver Vanadium

Always read the Material Safety Data Sheets (MSDS) that should be supplied with the material you are using. These MSDSs will give you the information regarding the kind and amount of fumes and gases that may be dangerous to your health.

Use special equipment, such as water or down draft welding/cutting tables, to capture fumes and gases.

Do not use the welding torch in an area where combustible or explosive gases or materials are located.

Phosgene, a toxic gas, is generated from the vapors of chlorinated solvents and cleansers. Remove all sources of these vapors.

ELECTRIC SHOCK Electric Shock can injure or kill. The arc welding process uses and produces high voltage electrical energy. This electric energy can cause severe or fatal shock to the operator or others in the workplace.

Never touch any parts that are electrically “live” or “hot.” Wear dry gloves and clothing. Insulate yourself from the work piece or other parts of the welding

circuit. Repair or replace all worn or damaged parts. Extra care must be taken when the workplace is moist or damp. Install and maintain equipment according to NEC code, refer to relative standards. Disconnect power source before performing any service or repairs. Read and follow all the instructions in the Operating Manual.

FIRE AND EXPLOSION Fire and explosion can be caused by hot slag, sparks, or the arc weld.

Be sure there is no combustible or flammable material in the workplace. Any material that cannot be removed must be protected.

Ventilate all flammable or explosive vapors from the workplace. Do not cut or weld on containers that may have held combustibles. Provide a fire watch when working in an area where fire hazards may exist. Hydrogen gas may be formed and trapped under aluminum workpieces when they are cut

underwater, or while using a water table. Do not cut aluminum alloys underwater or on a water table unless the hydrogen gas can be eliminated or dissipated. Trapped hydrogen gas that is ignited will cause an explosion.

NOISE Noise can cause permanent hearing loss. Arc welding/cutting processes can cause noise levels to exceed safe limits. You must protect your ears from loud noise to prevent permanent loss of hearing.

To protect your hearing from loud noise, wear protective ear plugs and/ or ear muffs. Protect others in the workplace.

Noise levels should be measured to be sure the decibels (sound) do not exceed safe levels.

ARC WELDING RAYS Arc Welding/ Cutting Rays can injure your eyes and burn your skin. The arc welding/cutting process produces very bright ultra violet and infra red light. These arc rays will damage your eyes and burn your skin if you are not properly protected.

To protect your eyes, always wear a welding helmet or shield. Also always wear safety glasses with side shields, goggles or other protective eye wear.

Wear welding gloves and suitable clothing to protect your skin from the arc rays and sparks. Keep helmet and safety glasses in good condition. Replace lenses when cracked, chipped or dirty. Protect others in the work area from the arc rays. Use protective booths, screens or shields.

1.03 Transporting methods These units are equipped with a handle for carrying purposes.

WARNING: ELECTRIC SHOCK can kill.

DO NOT TOUCH live electrical parts. Disconnect input power conductors from de-energized supply line before moving the welding power source.

WARNING: FALLING EQUIPMENT can cause serious personal injury and equipment damage.

Lift unit with handle on top of case. Use handcart or similar device of adequate capacity. If using a fork lift vehicle, place and secure unit on a proper skid before transporting.

2.0 INSTALLATION RECOMMENDATION Installation Environment

DYNA MMA is designed for use in hazardous environments. Examples of environments with increased hazardous environments are - In locations in which freedom of movement is restricted, so that the operator is forced to perform the

work in a cramped (kneeling, sitting or lying) position with physical contact with conductive parts; In locations which are fully or partially limited by conductive elements, and in which there is a high risk of unavoidable or accidental contact by the operator, or in wet or damp hot locations where humidity or perspiration considerable reduces the skin resistance of the human body and the insulation properties of accessories.

Environments with hazardous environments do not include places where electrically conductive parts in the near vicinity of the operator, which can cause increased hazard, have been insulated. Installation Location

Be sure to locate the welder according to the following guidelines: In areas, free from moisture and dust. In areas, free from oil, steam and corrosive

gases. In areas, not exposed to direct sunlight or rain. Ambient temperature: between -10 degrees C

to 40 degrees C.

In areas, not subjected to abnormal vibration or shock.

Place at a distance of 304.79mm or more from walls or similar that could restrict natural airflow for cooling.

WARNING 1

FCW advises that this equipment be electrically connected by a qualified electrician.

2.03 Duty cycle

The duty cycle of a welding power source is the percentage of a ten (10) minute period that it can be operated at a given output without causing overheating and damage to the unit. If the welding amperes decrease, the duty cycle increases. If the welding amperes are increased beyond the rated output, the duty cycle will decrease.

WARNING: Exceeding the duty cycle ratings will cause the thermal overload protection circuit to become energized and shut down the output until has cooled to normal operating temperature

Continually exceeding the duty cycle ratings can cause damage to the welding power source.

NOTICE:

Due to variations that can occur in manufacture products, claimed performance, voltages, ratings, all capacities, measurements, dimensions and weights quoted are approximate only. Achievable capacities and ratings in use and operation will depend upon correct installation, use, applications, maintenance and service.

Parameter Description

Welding Current This parameter sets the welding current.

Arc Force This parameter provides a suitable short circuit current in STICK welding to improve electrode sticking and arc stability.

Hot Start This parameter operates in STICK weld mode and is used to improve the start characteristics for stick electrodes. e.g. low hydrogen electrodes. It sets the peak start current on top of the (WELD) current.

Long Arc This control provides a long Arc in STICK welding to improve characteristics for STICK electrodes.

Short Arc This control provides a short Arc in STICK welding to improve electrode restart quickly.

Down Slope Time This parameter operates in TIG modes only and is used to set the time for the welding current to ramp down, this control is used to eliminate the crater that can form at the completion of a weld.

Post-Flow

t2

This parameter operates in TIG modes only and is used to adjust the post gas flow time once the arc has extinguished. This control is used to dramatically reduce oxidation of the tungsten electrode. t2 = 5S

4.0 SET-UP FOR MMA (STICK) AND GTAW (TIG) Conventional operating procedures apply when using the welding power source, i.e. connect work lead

directly to work piece and welding cable is used to electrode holder. Wide safety margins provided by the coil design ensure that the welding power source will withstand short-term overload without adverse effects. The welding current range values should be used as a guide only. Current delivered to the arc is dependent on the welding arc voltage, and as welding arc voltage varies between different classes of electrodes, welding current at any one setting would vary according to the type of electrode in use. The operator should use the welding current range values as a guide, and then finally adjust the current setting to suit the application.

Figure 5 Set up for DYNA MMA Series

WARNING:

Before connecting the work clamp to the work and inserting the electrode in the electrode holder make sure the Primary power supply is switched off.

CAUTION 2:

Remove any packaging material prior to use. Do not block the air vents at the front or rear of the Welding Power Source.

7.0 BASIC ARC WELDING GUIDE 7.01 Electrode polarity

Stick electrodes are generally connected to the “+” terminal and the work lend to the “-“ terminal but if in doubt consult the electrode manufacturers literature. 7.02 Effects of stick welding various materials High tensile and alloy steels

The two most prominent effects of welding these steels are the formation of a hardened zone in the weld area, if suitable precautions are not taken, the occurrence in this zone of under-bead cracks. Hardened zone and under-bead cracks in the weld area may be reduced by using the correct electrodes, preheating, using higher current settings, using larger electrodes size, short runs for larger electrode deposits or tempering in a furnace.

Manganese steels The effect on manganese steel slow of cooling from high temperature is to embrittle it. For this reason it

is absolutely essential to keep manganese steel cool during welding by quenching after each weld or skip welding to distribute the heat.

Cast iron Most types of cast iron, expect white iron, are weldable. White iron, because of its extreme brittleness,

generally cracks when attempts are made to weld it. Trouble may also be experienced when welding white-heart malleable, due to the porosity caused by gas held in this type of iron.

Copper and alloys The most important factor is the high rate of heat conductivity of copper, so making preheating of heavy

sections necessary to give proper fusion of weld and base metal.

Types of Electrodes Arc welding electrodes are classified into a number of groups depending on their applications. There are

a great number of electrodes used for specialized industrial purposes, which are not of particular interest for everyday general work. These include some low hydrogen types for high tensile steel, cellulose types for welding large diameter pipes, etc. The range of electrodes dealt with in this publication will cover the vast majority of applications likely to be encountered; are all easy to use and all will work on even the most basic of welding machines.

Metals being joined Electrode Comments

9.03 Stick welding problems

Description Cause Remedy

1 Gas pockets or voids in weld metal (Porosity).

A Electrodes are damp. B Welding current is too large. C Surface impurities such as: oil,

grease, paint, etc.

A Dry electrodes before use. B Reduce welding current. C Clean joint before welding.

2 Crack occurring in weld metal soon after solidification commences.

A Rigidity of joint. B Insufficient throat thickness. C Cooling rate is too high.

A Redesign to relieve weld joint of severe stresses or use crack resistance electrodes.

B Travel slightly slower to allow greater build up in throat.

C Preheat plate and cool slowly. 3 A gap is left by

failure of the weld metal to fill the root of the weld.

A Welding current is too low. B Electrode too large for joint. C Insufficient gap. D Incorrect sequence.

A Increase welding current. B Use smaller diameter electrode. C Allow wider gap. D Use correct build-up sequence.

4 Portions of the weld run do not fuse to the surface of the metal or edge of the joint.

A Small electrodes used on heavy cold plate.

B Welding current is too low. C Wrong electrode angle. D Travel speed of electrode is too high. E Scale or dirt on joint surface.

A Use larger electrodes and preheat the plate.

B Increase welding current. C Adjust angle so the welding is

directed more into the base metal. D Reduce travel speed of electrode. E Clean surface before welding.

5 Non-metallic particles are trapped in the weld metal (slag inclusion).

A Non-metallic particles may be trapped in undercut from previous run.

B Joint preparation too restricted. C Irregular deposits allow slag to be

trapped. D Lack of penetration with slag trapped

beneath weld bead. E Rust or mill scale is preventing full

fusion. F Wrong electrode for position in which

welding is done.

A If bad undercut is present, clean slag out and cover with a run from a smaller diameter electrode.

B Allow for adequate penetration and room for cleaning out the slag.

C If very bad, chip or grind out irregularities.

D Use smaller electrode with sufficient current to give adequate penetration. Use suitable tools to remove all slag from corners.

E Clean joint before welding. F Use electrodes designed for position

in which welding is done, otherwise proper control of slag is difficult.

9.04 Power source problems

Description Possible Cause Remedy

1 The welding arc can not be established.

A The Primary supply voltage has not been switched on.

B The welding power source switch is switched off.

C Loose connections internally.

A Switch on the primary supply voltage.

B Switch on the welding power source.

C Have an accredited FCW service agent repair the connection.

2 Maximum output welding current can not be achieved with nominal Mains supply voltage.

Defective control circuit. Have an accredited FCW service agent inspect then repair the welder.

3 Welding current reduces when welding.

Poor work lead connection to the work piece.

Ensure that the work lead has a positive electrical connection to the work piece.

4 No gas flow when the torch trigger switch is depressed.

A Gas hose is cut. B Gas passage contains

impurities. C Gas regulator turned off.

A Replace gas hose. B Disconnect gas hose from the

rear of power source then raise gas pressure and blow out impurities.

C Turn gas regulator on.
