WARNING

Mar ‘95

ELECTRIC AND MAGNETIC FIELDSmay be dangerous

2.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and welding machines

2.b. EMF fields may interfere with some pacemakers, andwelders having a pacemaker should consult their physicianbefore welding.

2.c. Exposure to EMF fields in welding may have other healtheffects which are now not known.

2.d. All welders should use the following procedures in order tominimize exposure to EMF fields from the welding circuit:

2.d.1. Route the electrode and work cables together - Securethem with tape when possible.

2.d.2. Never coil the electrode lead around your body.

2.d.3. Do not place your body between the electrode andwork cables. If the electrode cable is on your right side, the work cable should also be on your right side.

2.d.4. Connect the work cable to the workpiece as close aspossible to the area being welded.

2.d.5. Do not work next to welding power source.

1.h. To avoid scalding, do not remove theradiator pressure cap when the engine ishot.

ARC RAYS can burn.4.a. Use a shield with the proper filter and cover

plates to protect your eyes from sparks andthe rays of the arc when welding or observingopen arc welding. Headshield and filter lensshould conform to ANSI Z87. I standards.

4.b. Use suitable clothing made from durable flame-resistantmaterial to protect your skin and that of your helpers fromthe arc rays.

4.c. Protect other nearby personnel with suitable, non-flammablescreening and/or warn them not to watch the arc nor exposethemselves to the arc rays or to hot spatter or metal.

ELECTRIC SHOCK cankill.3.a. The electrode and work (or ground) circuits

are electrically “hot” when the welder is on.Do not touch these “hot” parts with your bareskin or wet clothing. Wear dry, hole-free

gloves to insulate hands.

3.b. Insulate yourself from work and ground using dry insulation.Make certain the insulation is large enough to cover your fullarea of physical contact with work and ground.

In addition to the normal safety precautions, if weldingmust be performed under electrically hazardousconditions (in damp locations or while wearing wetclothing; on metal structures such as floors, gratings orscaffolds; when in cramped positions such as sitting,kneeling or lying, if there is a high risk of unavoidable oraccidental contact with the workpiece or ground) usethe following equipment:

• Semiautomatic DC Constant Voltage (Wire) Welder.• DC Manual (Stick) Welder.• AC Welder with Reduced Voltage Control.

3.c. In semiautomatic or automatic wire welding, the electrode,electrode reel, welding head, nozzle or semiautomaticwelding gun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electricalconnection with the metal being welded. The connectionshould be as close as possible to the area being welded.

3.e. Ground the work or metal to be welded to a good electrical(earth) ground.

3.f. Maintain the electrode holder, work clamp, welding cable andwelding machine in good, safe operating condition. Replacedamaged insulation.

3.g. Never dip the electrode in water for cooling.

3.h. Never simultaneously touch electrically “hot” parts ofelectrode holders connected to two welders because voltagebetween the two can be the total of the open circuit voltageof both welders.

3.i. When working above floor level, use a safety belt to protectyourself from a fall should you get a shock.

3.j. Also see Items 6.c. and 8.

FUMES AND GASEScan be dangerous.5.a. Welding may produce fumes and gases

hazardous to health. Avoid breathing thesefumes and gases.When welding, keepyour head out of the fume. Use enoughventilation and/or exhaust at the arc to keep

fumes and gases away from the breathing zone. Whenwelding with electrodes which require specialventilation such as stainless or hard facing (seeinstructions on container or MSDS) or on lead orcadmium plated steel and other metals or coatingswhich produce highly toxic fumes, keep exposure aslow as possible and below Threshold Limit Values (TLV)using local exhaust or mechanical ventilation. Inconfined spaces or in some circumstances, outdoors, arespirator may be required. Additional precautions arealso required when welding on galvanized steel.

5.b. Do not weld in locations near chlorinated hydrocarbon vaporscoming from degreasing, cleaning or spraying operations.The heat and rays of the arc can react with solvent vapors toform phosgene, a highly toxic gas, and other irritating prod-ucts.

5.c. Shielding gases used for arc welding can displace air andcause injury or death. Always use enough ventilation,especially in confined areas, to insure breathing air is safe.

5.d. Read and understand the manufacturer’s instructions for thisequipment and the consumables to be used, including thematerial safety data sheet (MSDS) and follow youremployer’s safety practices. MSDS forms are available fromyour welding distributor or from the manufacturer.

5.e. Also see item 1.b.

Mar ‘95

WELDING SPARKS cancause fire or explosion.6.a. Remove fire hazards from the welding area.

If this is not possible, cover them to preventthe welding sparks from starting a fire.Remember that welding sparks and hot

materials from welding can easily go through small cracksand openings to adjacent areas. Avoid welding nearhydraulic lines. Have a fire extinguisher readily available.

6.b. Where compressed gases are to be used at the job site,special precautions should be used to prevent hazardoussituations. Refer to “Safety in Welding and Cutting” (ANSIStandard Z49.1) and the operating information for theequipment being used.

6.c. When not welding, make certain no part of the electrodecircuit is touching the work or ground. Accidental contactcan cause overheating and create a fire hazard.

6.d. Do not heat, cut or weld tanks, drums or containers until theproper steps have been taken to insure that such procedureswill not cause flammable or toxic vapors from substancesinside. They can cause an explosion even though they havebeen “cleaned”. For information, purchase “RecommendedSafe Practices for the Preparation for Welding and Cutting ofContainers and Piping That Have Held HazardousSubstances”, AWS F4.1 from the American Welding Society(see address above).

6.e. Vent hollow castings or containers before heating, cutting orwelding. They may explode.

6.f. Sparks and spatter are thrown from the welding arc. Wear oilfree protective garments such as leather gloves, heavy shirt,cuffless trousers, high shoes and a cap over your hair. Wearear plugs when welding out of position or in confined places.Always wear safety glasses with side shields when in awelding area.

6.g. Connect the work cable to the work as close to the weldingarea as practical. Work cables connected to the buildingframework or other locations away from the welding areaincrease the possibility of the welding current passingthrough lifting chains, crane cables or other alternate cir-cuits. This can create fire hazards or overheat lifting chainsor cables until they fail.

PRÉCAUTIONS DE SÛRETÉPour votre propre protection lire et observer toutes les instructionset les précautions de sûreté specifiques qui parraissent dans cemanuel aussi bien que les précautions de sûreté générales suiv-antes:

Sûreté Pour Soudage A L’Arc1. Protegez-vous contre la secousse électrique:

a. Les circuits à l’électrode et à la piéce sont sous tensionquand la machine à souder est en marche. Eviter toujourstout contact entre les parties sous tension et la peau nueou les vétements mouillés. Porter des gants secs et sanstrous pour isoler les mains.

b. Faire trés attention de bien s’isoler de la masse quand onsoude dans des endroits humides, ou sur un planchermetallique ou des grilles metalliques, principalement dans les positions assis ou couché pour lesquelles une grandepartie du corps peut être en contact avec la masse.

c. Maintenir le porte-électrode, la pince de masse, le câblede soudage et la machine à souder en bon et sûr étatdefonctionnement.

d.Ne jamais plonger le porte-électrode dans l’eau pour lerefroidir.

e. Ne jamais toucher simultanément les parties sous tensiondes porte-électrodes connectés à deux machines à souderparce que la tension entre les deux pinces peut être letotal de la tension à vide des deux machines.

f. Si on utilise la machine à souder comme une source decourant pour soudage semi-automatique, ces precautionspour le porte-électrode s’applicuent aussi au pistolet desoudage.

2. Dans le cas de travail au dessus du niveau du sol, se protégercontre les chutes dans le cas ou on recoit un choc. Ne jamaisenrouler le câble-électrode autour de n’importe quelle partiedu corps.

3. Un coup d’arc peut être plus sévère qu’un coup de soliel,donc:

a. Utiliser un bon masque avec un verre filtrant appropriéainsi qu’un verre blanc afin de se protéger les yeux du ray-onnement de l’arc et des projections quand on soude ouquand on regarde l’arc.

b. Porter des vêtements convenables afin de protéger lapeau de soudeur et des aides contre le rayonnement del‘arc.

c. Protéger l’autre personnel travaillant à proximité ausoudage à l’aide d’écrans appropriés et non-inflammables.

4. Des gouttes de laitier en fusion sont émises de l’arc desoudage. Se protéger avec des vêtements de protection libresde l’huile, tels que les gants en cuir, chemise épaisse, pan-talons sans revers, et chaussures montantes.

5. Toujours porter des lunettes de sécurité dans la zone desoudage. Utiliser des lunettes avec écrans lateraux dans les

zones où l’on pique le laitier.

6. Eloigner les matériaux inflammables ou les recouvrir afin deprévenir tout risque d’incendie dû aux étincelles.

7. Quand on ne soude pas, poser la pince à une endroit isolé dela masse. Un court-circuit accidental peut provoquer unéchauffement et un risque d’incendie.

8. S’assurer que la masse est connectée le plus prés possiblede la zone de travail qu’il est pratique de le faire. Si on placela masse sur la charpente de la construction ou d’autresendroits éloignés de la zone de travail, on augmente le risquede voir passer le courant de soudage par les chaines de lev-age, câbles de grue, ou autres circuits. Cela peut provoquerdes risques d’incendie ou d’echauffement des chaines et descâbles jusqu’à ce qu’ils se rompent.

9. Assurer une ventilation suffisante dans la zone de soudage.Ceci est particuliérement important pour le soudage de tôlesgalvanisées plombées, ou cadmiées ou tout autre métal quiproduit des fumeés toxiques.

10. Ne pas souder en présence de vapeurs de chlore provenantd’opérations de dégraissage, nettoyage ou pistolage. Lachaleur ou les rayons de l’arc peuvent réagir avec les vapeursdu solvant pour produire du phosgéne (gas fortement toxique)ou autres produits irritants.

11. Pour obtenir de plus amples renseignements sur la sûreté,voir le code “Code for safety in welding and cutting” CSAStandard W 117.2-1974.

PRÉCAUTIONS DE SÛRETÉ POURLES MACHINES À SOUDER ÀTRANSFORMATEUR ET ÀREDRESSEUR

1. Relier à la terre le chassis du poste conformement au code del’électricité et aux recommendations du fabricant. Le dispositifde montage ou la piece à souder doit être branché à unebonne mise à la terre.

2. Autant que possible, I’installation et l’entretien du poste seronteffectués par un électricien qualifié.

3. Avant de faires des travaux à l’interieur de poste, la debranch-er à l’interrupteur à la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leurplace.

Where the workpiece is not bonded to earth for electrical safety, not connected to earth because of its s

position, e.g., ships hull or building steelwork, a connection bonding the workpiece to earth may reduce

in some, but not all instances. Care should be taken to prevent the earthing of the workpiece increasing

earth should be made by a direct connection to the workpiece, but in some countries where direct conn

permitted, the bonding should be achieved by suitable capacitance, selected according to national regu

V350-PRO (CE)

PARALLEL OPERATIONThe V350-PRO (CE) are operable in parallel in CCmode. For best results, the currents of each machineshould be reasonably well shared. As an example,with two machines set up in parallel for a 400 ampprocedure, each machine should be set to deliverapproximately 200 amps, not 300 amps from one and100 amps from the other. This will minimize nuisanceshutdown conditions. In general, more than twomachines in parallel will not be effective due to thevoltage requirements of procedures in that powerrange.To set machine outputs, start with output control potsand arc control pots in identical positions. Use theoutput control pots to balance the currents and main-tain the desired voltage or current. The arc controlpots should be kept identical on the two machines.

QUICK DISCONNECT PLUGS

A quick disconnect system is used for the weldingcable connections. The welding plug included with themachine is designed to accept a welding cable size of1/0 to 2/0.

1. Remote 25mm (1 in.) of welding cable insulation.

2. Slide rubber boot onto cable end. The boot endmay be trimmed to match the cable diameter.Soap or other lubricant will help to slide the bootover the cable.

3. Slide the copper tube into the brass plug.

4. Insert cable into copper tube.

5. Tighten set screw to collapse copper tube. Screwmust apply pressure against welding cable. Thetop of the set screw will be well below the surfaceof the brass plug after tightening.

6. Slide rubber boot over brass plug. The rubberboot must be positioned to completely cover allelectrical surfaces after the plug is locked into thereceptacle.

GENERAL DESCRIPTION

PRODUCT DESCRIPTION & DUTY CYCLEThe Invertec V350-PRO (CE) offers multi mode CVand CC DC welding and is rated at 350 amps, 34 voltsat a 60% duty cycle with 3 phase input. It is also ratedat 320 amps with single phase input. It is rated at 275amps, 100% duty cycle.

OPERATIONAL FEATURES and CONTROLS:

UPPER CONTROL PANEL1. AMPS Meter• Prior to STICK or TIG operation (current flow), the

meter displays preset current value (either 2 ampsor +/- 3% (e.g. 3 amps on 100), whichever isgreater).

• Prior to CV operation, the meter displays four dash-es indicating non-presettable AMPS.

• During welding, this meter displays actual averageamps.

• After welding, the meter holds the actual currentvalue for 5 seconds. Output adjustment while in the"hold" period results in the "prior to operation" char-acteristics stated above. The displays blink indicat-ing that the machine is in the "Hold" period.

2. VOLT METER• Prior to CV operation (current flow), the meter dis-

plays desired preset voltage value (+/- .5V).• Prior to STICK or TIG operation, the meter displays

the Open Circuit Voltage of the Power Source orfour dashes if the output has not been turned on.

• During welding, this meter displays actual averagevolts.

• After welding, the meter holds the actual voltagevalue for 5 seconds. The displays blink indicatingthat the machine is in the "Hold" period.

• Output adjustment while in the "hold" period resultsin the "prior to operation" characteristics statedabove.

3. OUTPUT CONTROL• Output control is conducted via a single turn poten-

tiometer.• Adjustment is indicated by the meters as stated

above.• When in TIG modes, this control sets the maximum

welding current. Full depression of a foot or handAmptrol results in the preset level of current.

4. WELD TERMINALS-REMOTE , ON• Two status lights indicate the location of trigger con-

trol as determined by the "WELD TERMINALS"push button.

• If trigger control is local "weld terminals on", the ONdisplay will be lit.

• If trigger control is remote "weld terminals remotelycontrolled", the REMOTE display will be lit.

• The unit will power up in "pre-determined preferred"trigger modes.

STICK = ON TIG and CV = ON or REMOTE depending if remoteoutput controls are connected to the machine.

5. THERMAL• This status light indicates when the power source

has been driven into thermal overload. If the outputterminals were "ON", the "ON" light will blink indicat-ing that the output will be turned back on once theunit cools down to an acceptable temperature level.If the unit was operating in the "REMOTE" mode,the trigger will need to be opened before or after thethermal has cleared and closed after the machinehas cooled down to an acceptable temperature toestablish output.

6. CONTROL-REMOTE , LOCAL• Two status lights indicate the location of output con-

trol as pre-determined by the power sources auto-configure system.

• The LOCAL display will be lit when control is at thepower source.

• The REMOTE display will be lit when a remotepot/control is detected.

These Output Control configurations can be overrid-den (switched) with the CONTROL push button.When changed, the unit will power up in the configura-tion it was in when it was last powered down.

Hidden Middle Control Panel – ProcessSet Up PanelThe middle control panel is removable to allow forupgrades (see Field Installed Options/Accessories).Additionally, this panel is hidden by an access door toreduce appeared complexity and provide protection tothe controls.

7. WELD MODE SELECTThe Mode Control button selects the following weldingmodes desired.

CC-STICK SOFT: The Stick Soft process featurescontinuous control ranging from 5 to 425 amps. Thismode was intended for most SMAW applications, andArc Gouging.

• Arc Gouging: Setting the output of the Stick Softmode to 425 amps will enable the arc-gougingmode. The actual output current will depend on thesize of carbon used. The recommended maximumsize carbon is 5/16".

• The Hot Start control regulates the starting currentat arc initiation. Hot Start can be adjusted from min-imum (0), with no additional current added at arcstart, to maximum (10), with double the preset cur-rent or 425 amps (max of machine) added for thefirst second after arc initiation.

• The Arc Control regulates the Arc Force to adjustthe short circuit current. The minimum setting (-10)will produce a "soft" arc and will produce minimalspatter. The maximum setting (+10) will produce a"crisp" arc and will minimize electrode sticking.

CC-STICK CRISP: The Stick Crisp mode featurescontinuous control from 5 to 425 amps. This modewas intended primarily for pipe welding applications.

• The Hot Start control regulates the starting currentat arc initiation. Hot Start can adjust starting currentup or down by 25% of the preset value. The recom-mended setting for Hot Start is 5 where the initialcurrent is equal to the preset current.

B-3OPERATIONB-3

• The Arc Control regulates the relative Slope of theprocess. Slope dynamically controls the force thearc has to penetrate an open root. At the minimumsetting, Arc Control is very soft and is similar to theStick Soft mode. At the maximum setting, the slopeis reduced, the OCV is reduced, and the operatorhas full control off the arc force required to pene-trate an open root joint. For vertical down, open rootpipe welding applications, the recommended settingis between 8 and 10.

• During welding, a boost circuit increases the avail-able voltage to minimize pop outs. The boost circuitis independent of the OCV and only operates whenan arc is lit.

TIG GTAW: The TIG mode features continuous con-trol from 5 to 425 amps. The TIG mode can be run ineither the TIG touch start or high frequency assistedstart mode.

• The Hot Start control selects the starting modedesired. A setting of less than 5, the TIG lift startmode is selected. The OCV is controlled below 10vand the short circuit "TIG touch" current is main-tained at 25 amps independent of the preset current.When the tungsten is lifted, an arc is initiated and theoutput is regulated at the preset value. Hot start set-tings between 0 and 5 regulate the arc initiation cur-rent. A setting of 5 results in the most positive arc ini-tiation. A setting of 0 reduces hot start.

• Hot Start settings between 5 and 10, select high fre-quency assisted starting TIG mode. In this range, theOCV of the machine is controlled between 50 and 70volts. If using the Lincoln K930-1 TIG Module, setthe Hot start to 10 for maximum OCV.

• The Arc Control is not used in the TIG mode.

CV-WIRE: The CV-WIRE mode features continuouscontrol from 10 to 45 volts. The mode was intendedfor most GMAW, FCAW, and MCAW applications.

• The Hot Start control is not used in the CV-WIREmode.

• The Arc Control regulates pinch effect. At the mini-mum setting (-10), minimizes pinch and results in asoft arc. Low pinch settings are preferable for weld-ing with gas mixes containing mostly inert gases. Atthe maximum setting (+10), maximizes pinch effectand results in a crisp arc. High pinch settings arepreferable for welding FCAW and GMAW with CO2.

CV-INNERSHIELD: The CV-INNERSHIELD modefeatures continuous control from 10 to 45 volts. Thismode was designed for self-shielded flux cored wiresthat require tight voltage control.

• The Hot Start control is not used in the CV-FLUXCORED mode.

• The Arc Control regulates pinch effect. At the mini-mum setting (-10), minimizes pinch and results in asoft arc. At the maximum setting (+10), maximizespinch effect and results in a crisp arc. Most self-shielded wires work well at an Arc Control setting of 5.

8. HOT START and ARC CONTROL features havedifferent functions depending on the welding Modethat is active. Each feature is described under thewelding mode heading. (See Item 6 for specifiedMode Operation)

LOWER CASE FRONTThe output studs, line switch and remote connectorare located on the lower case front.

9. Both STUDS contain "Twist-Mate" connectorinserts.

• The Negative stud is configured to accept thepass through gas system.

10. The ON-OFF switch is a 3-phase circuit breakerrated at 100 amps per leg.

11. The METER POLARITY switch is located abovethe output connectors. The switch provides a workconnection for wire feeder voltmeters. Place theswitch in the position of the electrode polarity indi-cated by the decal. The switch does not changethe welding polarity.

12. 6-PIN AMPENOL for remote control.

REMOTE CONTROL of the OUTPUT CON-TROL and WELD TERMINALSThe Invertec V350-PRO (CE) has auto sensing ofremote output controls.If after connecting or removinga remote, the Invertec V350-PRO (CE) did not config-ured the way you would like the local or remote con-trol settings can be changed by pushing the OUTPUTCONTROL or WELD TERMINAL button. (A user can-not select between the 6 and 14 pin amphenols.)

CV modes• The remote will default to the 14-pin amphenol

remote if a remote is connected to either of the 14-pin amphenols and the 6-pin amphenol. Note: Onlyone of the 14-pin amphenols can have a remotecontrol connected at a time. If no remote is connect-ed to either of the 14-pin amphenols then theremote will default to the 6-pin amphenol if a remoteis connected to it.

• If a remote control is connected or is not connect-ed to any of the amphenols the WELD TERMINALcontrol will default to REMOTE.

B-4OPERATIONB-4TIG mode• The remote will default to the 6-pin amphenol if a

remote control is connected to the 6-pin amphenoland one of the 14-pin amphenols. If a remote is notconnected to the 6-pin amphenol then the remotewill default to the 14-pin amphenols if a remote isconnected to one of the 14-pin amphenols.

• If a remote control is connected to any of theamphenols the WELD TERMINAL control willdefault to REMOTE. If there are not any remotecontrol devices attached the WELD TERMINAL con-trol will default to ON.

CC-Stick modes • The remote will default to only the 6-pin amphenol if

a remote is connected to it.• The WELD TERMINAL control will default to ON

with or without a remote connected.

Types of Remote OUTPUT CONTROL• The Invertec V350-PRO (CE)’s Output Control can

be controlled by either a potentiometer connectedbetween 77 & 75 with the wiper connected to 76 ora 0V to 10V DC supply connected between 76 & 75.(76 needs to be positive)

• 14-Pin Amphenol lead 75 is pin G, lead 76 is pin Fand lead 77 is pin E.

• 6-Pin Amphenol lead 75 is pin C, lead 76 is pin Band lead 77 is pin A.

Potentiometer Control• The total resistance should be between 2000 ohms

(2K) and 10,000 ohms (10K)• The machine output will be at minimum when lead

76 (wiper) is at the end of the potentiometer that isconnected to 75. The machine’s output will increaseas the wiper of the potentiometer is moved to theend that is connected to 77. (Note: In TIG mode,moving the lead 76 (wiper) to lead 77 would pro-duce the current that has been set by the InvertecV350-PRO (CE)’s front panel Output Control.)

• Remotes of this type offered by Lincoln Electric arethe K857, K812 and K870.

Voltage Control• The supply should be an isolated supply. (Not refer-

enced to earth ground, any auxiliary power from theInvertec V350-PRO (CE) or the welding output) Thesupply should be capable of supplying at least 20mA.

• 0 volts supplied to 76 will set the Invertec V350-PRO (CE) to minimum output for the mode that hasbeen selected while 10 volts supplied to 76 will setthe Invertec V350-PRO (CE) to the maximum outputfor the mode. (Note: In TIG mode, 10 volts suppliedto lead 76 would produce the current that has beenset by the Invertec V350-PRO (CE)’s front panelOutput Control.)

Types of Remote WELD TERMINAL Control• The Invertec V350-PRO (CE)’s Weld Terminals can

be controlled from each of the amphenol connec-tors. The circuit has a nominal OCV of 15VDC andrequires a dry contact closure (less than 100 ohms)to activate the output of the Invertec V350-PRO(CE).

• 14 Pin Amphenols the Weld Terminals are controlledfrom pins C (lead 2) and pin D (lead 4). Pin C is posi-tive.

• 6 Pin Amphenol the Weld Terminals are controlledfrom pin D (lead 2) and pin E (lead 4). In the 6-pinamphenol pin D is positive.

DESIGN FEATURES and ADVANTAGES • Multiple process DC output range: 5 - 425 amps• Pre-settable welding outputs.• Built-in Line Voltage Compensation holds the output

VISUAL INSPECTION

Clean interior of machine with a low pressure airstream. Make a thorough inspection of all compo-nents. Look for signs of overheating, broken leads orother obvious problems. Many problems can beuncovered with a good visual inspection.

ROUTINE MAINTENANCE

1. Every 6 months or so the machine should becleaned with a low pressure airstream. Keepingthe machine clean will result in cooler operationand higher reliability. Be sure to clean these areas:

• All printed circuit boards• Power switch• Main transformer• Input rectifier • Auxiliary Transformer• Reconnect Switch Area

2. Examine the sheet metal case for dents or breakage.Repair the case as required. Keep the case in good con-dition to insure that high voltage parts are protected andcorrect spacings are maintained. All external sheetmetal screws must be in place to insure case strengthand electrical ground continuity.

PERIODIC MAINTENANCE

Overload ProtectionThe machine is electrically protected from producinghigh output currents. Should the output currentexceed 430A, an electronic protection circuit willreduce the current to approximately 100A. Themachine will continue to produce this low current untilthe protection circuit is reset. Reset occurs when theoutput load is removed.

Thermal ProtectionThermostats protect the machine from excessiveoperating temperatures. Excessive temperatures maybe caused by a lack of cooling air or operating themachine beyond the duty cycle and output rating. Ifexcessive operating temperature should occur, thethermostat will prevent output voltage or current. Themeter will remain energized during this time.

Thermostats are self-resetting once the machine coolssufficiently. If the thermostat shutdown was caused byexcessive output or duty cycle and the fan is operatingnormally, the Power Switch may be left on and thereset should occur within a 15 minute period.
