ELECTRIC SHOCK can kill.
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 bare
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 full area of physical contact with work and ground.
In addition to the normal safety precautions, if welding must be performed under electrically hazardous conditions (in damp locations or while wearing wet clothing; on metal structures such as floors, gratings or scaffolds; when in cramped positions such as sitting, kneeling or lying, if there is a high risk of unavoidable or accidental contact with the workpiece or ground) use the 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 semiautomatic welding gun are also electrically “hot”.
3.d. Always be sure the work cable makes a good electrical connection with the metal being welded. The connection should 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 and welding machine in good, safe operating condition. Replace damaged insulation.
3.g. Never dip the electrode in water for cooling.
3.h. Never simultaneously touch electrically “hot” parts of electrode holders connected to two welders because voltage between the two can be the total of the open circuit voltage of both welders.
3.i. When working above floor level, use a safety belt to protect yourself from a fall should you get a shock.

ARC RAYS can burn.
4.a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87. I standards.
4.b. Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays.
4.c. Protect other nearby personnel with suitable, non-flammable screening and/or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.
FUMES AND GASES can be dangerous.
5.a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. When welding, keep your head out of the fume. Use enough
fumes and gases away from the breathing zone. When
welding with electrodes which require special ventilation such as stainless or hard facing (see instructions on container or MSDS) or on lead or cadmium plated steel and other metals or coatings which produce highly toxic fumes, keep exposure as low as possible and below Threshold Limit Values (TLV) using local exhaust or mechanical ventilation. In confined spaces or in some circumstances, outdoors, a respirator may be required. Additional precautions are also required when welding on galvanized steel.
5. b. The operation of welding fume control equipment is affected by various factors including proper use and positioning of the equipment, maintenance of the equipment and the spe­cific welding procedure and application involved. Worker exposure level should be checked upon installation and periodically thereafter to be certain it is within applicable OSHA PEL and ACGIH TLV limits.
5.c.
Do not weld in locations near chlorinated hydrocarbon coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors form phosgene, a highly toxic gas, and other irritating prod­ucts.
5.d. Shielding gases used for arc welding can displace air and
cause injury or death. Always use enough ventilation, especially in confined areas, to insure breathing air is safe.

WELDING and CUTTING SPARKS can cause fire or explosion.
6.a.
Remove fire hazards from the welding area.
If this is not possible, cover them to prevent
Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic 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 hazardous situations. Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1) and the operating information for the equipment being used.
6.c. When not welding, make certain no part of the electrode circuit is touching the work or ground. Accidental contact can cause overheating and create a fire hazard.
6.d. Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to insure that such procedures will not cause flammable or toxic vapors from substances inside. They can cause an explosion even been “cleaned”. For information, purchase “Recommended Safe Practices for the Containers and Piping That Have Held Hazardous Substances”, AWS F4.1 from the American Welding Society
(see address above).
6.e. Vent hollow castings or containers before heating, cutting or welding. They may explode.
Sparks and spatter are thrown from the welding arc. Wear oil
6.f. free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes and a cap over your hair. Wear ear plugs when welding out of position or in confined places. Always wear safety glasses with side shields when in a welding area.
6.g. Connect the work cable to the work as close to the welding area as practical. Work cables connected to the building framework or other locations away from the welding area increase the possibility of the welding current passing through lifting chains, crane cables or other alternate cir­cuits. This can create fire hazards or overheat lifting chains or cables until they fail.

PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instructions et les précautions de sûreté specifiques qui parraissent dans ce manuel aussi bien que les précautions de sûreté générales suiv­antes:
Sûreté Pour Soudage A LʼArc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à lʼélectrode et à la piéce sont sous tension
quand la machine à souder est en marche. Eviter toujours tout contact entre les parties sous tension et la peau nue ou les vétements mouillés. Porter des gants secs et sans trous pour isoler les mains.
b. Faire trés attention de bien sʼisoler de la masse quand on
soude dans des endroits humides, ou sur un plancher metallique ou des grilles metalliques, principalement dans les positions assis ou couché pour lesquelles une grande partie du corps peut être en contact avec la masse.
c. Maintenir le porte-électrode, la pince de masse, le câble
de soudage et la machine à souder en bon et sûr état defonctionnement.
d.Ne jamais plonger le porte-électrode dans lʼeau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à souder parce que la tension entre les deux pinces peut être le total de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions pour le porte-électrode sʼapplicuent aussi au pistolet de soudage.
2. Dans le cas de travail au dessus du niveau du sol, se protéger contre les chutes dans le cas ou on recoit un choc. Ne jamais enrouler le câble-électrode autour de nʼimporte quelle partie du corps.
3. Un coup dʼarc peut être plus sévère quʼun coup de soliel, donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi quʼun verre blanc afin de se protéger les yeux du ray­onnement de lʼarc et des projections quand on soude ou quand on regarde lʼarc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de lʻarc.
c. Protéger lʼautre personnel travaillant à proximité au
soudage à lʼaide dʼécrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de lʼarc de soudage. Se protéger avec des vêtements de protection libres de lʼhuile, tels que les gants en cuir, chemise épaisse, pan­talons sans revers, et chaussures montantes.
5. Toujours porter des lunettes de sécurité dans la zone de soudage. Utiliser des lunettes avec écrans lateraux dans les zones où lʼon pique le laitier.
6. Eloigner les matériaux inflammables ou les recouvrir afin de prévenir tout risque dʼincendie dû aux étincelles.
7. Quandonnesoude pas, poser la pince à une endroit isolé de la masse. Un court-circuit accidental peut provoquer un échauffement et un risque dʼincendie.
8. Sʼassurer que la masse est connectée le plus prés possible de la zone de travail quʼil est pratique de le faire. Si on place la masse sur la charpente de la construction ou dʼautres endroits éloignés de la zone de travail, on augmente le risque de voir passer le courant de soudage par les chaines de lev­age, câbles de grue, ou autres circuits. Cela peut provoquer des risques dʼincendie ou dʼechauffement des chaines et des câbles jusquʼà ce quʼils se rompent.
9. Assurer une ventilation suffisante dans la zone de soudage. Ceci est particuliérement important pour le soudage de tôles galvanisées plombées, ou cadmiées ou tout autre métal qui produit des fumeés toxiques.
10. Ne pas souder en présence de vapeurs de chlore provenant dʼopérations de dégraissage, nettoyage ou pistolage. La chaleur ou les rayons de lʼarc peuvent réagir avec les vapeurs du 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” CSA Standard W 117.2-1974.
PRÉCAUTIONS DE SÛRETÉ POUR LES MACHINES À SOUDER À TRANSFORMATEUR ET À REDRESSEUR
1. Relier à la terre le chassis du poste conformement au code de lʼélectricité et aux recommendations du fabricant. Le dispositif de montage ou la piece à souder doit être branché à une bonne mise à la terre.
2. Autant que possible, Iʼinstallation et lʼentretien du poste seront effectués par un électricien qualifié.
3. Avant de faires des travaux à lʼinterieur de poste, la debranch­er à lʼinterrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur place.

FIGURE B.1 - CONTROL PANEL KEYS
1. Input POWER ON/OFF Switch
This toggle switch turns the machine on or off. Putting the switch in the ON “ ” position ener­gizes the machineʼs input contactor applying input power to the machine. Switching the switch to the OFF “ ” position de-energizes the input contactor.
2. POWER Light
When the POWER switch is in the ON position the machineʼs white POWER light will illuminate. If the input contactor de-energizes the machine in an abnormal situation the pilot light will still illuminate. In this situation it may be necessary to reset the machine by switching the POWER switch to the OFF and then to the ON position. (See Overload, Overcurrent, and Fault Protection Section)
3. OUTPUT CONTROL
This control provides continuous control of the machineʼs output voltage and current from mini­mum to maximum (typical full pot range between

15 to 44 volts and 90 to 750 amps) as it is rotated clock-wise. Voltage or current control is deter­mined by setting of Mode Switch (CV or CC).
4. OUTPUT TERMINALS ON/REMOTE Switch
When this switch is in the REMOTE “ ” posi­tion, the DC-600ʼs output terminals will be electri­cally “cold” until a remote device such as a wire feeder closes the #2 and #4 circuit in the MS­receptacle or terminal strip (T.S.2). When this switch is in the ON “ ” position the machineʼs output terminals will be electrically energized all the time.
5. LOCAL/REMOTE Switch
When this switch is set to the LOCAL “ “ posi­tion, control of the output voltage and current is via the OUTPUT CONTROL on the DC-600ʼs control panel. When this switch is set to the REMOTE “ ” position, control is through a remote source such as a wire feeder via the #75, #76, and #77 leads in the MS-receptacle or terminal strip (T.S.1).

7. 115VAC GFCI Receptacle (60 Hertz Models)
This receptacle provides up to 15 amps of 115 VAC auxiliary power.
8. 115VAC 15 Amp Circuit Breaker
This breaker protects the 115 VAC auxiliary cir­cuits located in the gfci receptacle, terminal strip (T.S.2) and MS-receptacle.
9. 42VAC 10 Amp Circuit Breaker
This breaker protects the 42VAC auxiliary circuits located in the terminal strip (T.S.2) and MS-recep­tacle.
10.14 Pin MS-Receptacle
This connector provides easy connection for a wire feeder control cable. It provides connections for auxiliary power, output switching, remote output control, wire feeder voltmeter sense lead and ground. Refer to 14 Pin MS Type Receptacle in the Installation Section for information about the cir­cuits made available at this receptacle.
11.Terminal Strip Cover Panel
Rotate this panel to gain access to the circuits made available at the two terminal strips (T.S.1 and T.S.2). These terminal strips contains the same circuits as the 14 pin MS-receptacle. There is a box connector adjacent to this cover for routing leads to the terminal strips.
AUXILIARY POWER IN MS-RECEPTACLE
42 volt AC auxiliary power, as required for some wire feeders, is available through the wire feeder MS­receptacle. A 10 amp circuit breaker protects the 42 volt circuit from overloads.
DC-600 machines can also supply 115 volt AC auxil­iary power through the wire feeder receptacle. A 15 amp circuit breaker protects the 115 volt circuit from overloads.
OVERLOAD, OVERCURRENT, AND FAULT PROTECTION
This welder has thermostatic protection from exces­sive duty cycles, overloads, loss of cooling, and high ambient temperatures. When the welder is subjected to an overload or loss of cooling, a thermostat will open. The input contactor will open and remain open until the machine cools; the white POWER light stays illuminated. No welding is possible during this cool down period. The machine will reset automatically when the thermostat cools.
The power source is also protected against overcur­rents in the SCR bridge assembly through an elec­tronic protection circuit. This circuit senses currents over 780 amps on the power source and opens the input contactor should the overcurrent remain for a predetermined time (the white POWER light stays illu­minated). The predetermined time varies with the amount of overcurrent; the greater the overcurrent, the shorter the time. The input contactor will remain open until the power source is manually started by resetting the POWER ON/OFF toggle switch.
12.Negative Output Terminal
This output terminal is for connecting a welding cable. To change welding polarity and for proper welding cable size refer to Electrode and Work Cables in the Installation Section.
13.Positive Output Terminal
This output terminal is for connecting a welding cable. To change welding polarity and for proper welding cable size refer to Electrode and Work Cables in the Installation Section.
DC-600 RED-D-ARC
The power source circuitry is protected from faults on leads 75, 76, or 77. If any of these leads are connect­ed to either the positive or negative output leads, the DC-600 will either shut down completely (input con­tactor opens and white POWER light stays illuminat­ed), or will operate at minimum output thus preventing any damage to the DC-600. If DC-600 shuts down, it must be manually started by resetting the POWER ON/OFF toggle switch.

OPERATING STEPS
The following procedures are for using the DC-600 in the local control mode of operation. For remote control of the machine, see the Remote Control of Machine Operation section.
Before operating the machine, make sure you have all materials needed to complete the job. Be sure you are familiar with and have taken all possible safety pre­cautions before starting work. It is important that you follow these operating steps each time you use the machine.
1. Turn on the main AC power supply to the machine.
2. Connect the #21 work lead to either + or - on ter­minal strip (T.S.2).
3. Set the Welding Mode switch to welding process being used:
CC STICK (for SMAW and AAC)
CV SUBMERGED ARC (for SAW)
CV INNERSHIELD (for FCAW and GMAW)
4. Turn the POWER ON/OFF Toggle Switch to the “ON” position
The white pilot light glows.
The fan starts.
5. Set OUTPUT CONTROL Potentiometer to desired voltage or current.
6. Set the OUTPUT TERMINALS switch to either “ON” ( output terminals energized) or “REMOTE” (output terminals energized when #2 and #4 closed by remote device such as wire feeder)
REMOTE CONTROL OF MACHINE OPERATION
The toggle switch on the control panel labeled “Remote - Panel” gives the operator the option of con­trolling the machine output from a remote location. If in the Remote position a wire feeder with remote con­trol capabilities or a remote control device such as a K775 must be connected to terminals 75, 76, and 77. Refer to Accessories Section for wire feeder remote information.
WELDING PROCEDURE RECOMMENDATIONS
Select Welding Mode Switch position based on type of welding to be done.
1. Innershield Welding (FCAW)/MIG (GMAW)
Welding: Use the CV INNERSHIELD mode.
2. Submerged Arc Welding (SAW): Use the CV SUBMERGED ARC mode. If performing high speed welding, switch between the CV Submerged Arc and the CV Innershield mode and use the mode that produces the best welding results.
3. Air/Carbon Arc Cutting (CAC) / Stick Welding
(SMAW) / High Current, Large Puddle Submerged Arc Welding (SAW): Use the CC STICK mode. When the DC-600 is used for Air/Carbon Arc cut­ting, the OUTPUT CONTROL potentiometer should be set to "9" initially. Based on the size of the carbon being used or the process, turn the potentiometer to a lower setting as required by the process. You can use carbon rods up to 3/8" in diameter at currents as high as 750 amps with excellent arc control. The welder protection circuit protects the machine from extremely high short circuiting pulses.
7. Make the weld.

SEMI-AUTOMATIC AND AUTOMATIC WIRE FEEDING WITH THE DC-600 AND WIRE FEEDERS
When using the DC-600 with semi-automatic or auto­matic wire feeding equipment and for stick welding or air/carbon arc cutting, it is recommended that the optional MULTI-PROCESS SWITCH be used. This switch permits you to easily change the polarity of the connected wire feeding equipment or switch to stick welding or air/carbon arc cutting.
NA-3 AUTOMATIC WIRE FEEDER
1. Set the DC-600 LOCAL/REMOTE Switch to REMOTE. Set the OUTPUT TERMINALS switch to REMOTE. NOTE: Later model NA-3 automatic wire feeders are capable of cold starts when the NA-3 Mode switch is in the CV or CC mode posi­tion. Some earlier models are capable of cold starting only in the CC mode position. Cold start­ing enables you to inch the wire down to the work, automatically stop, and automatically energize the flux hopper valve.
2. Set the DC-600 welding mode switch for the desired process: CV SUBMERGED ARC, CV INNERSHIELD mode or CC STICK mode.
3. Set the NA-3 mode Switch Position to either CV or CC to match the DC-600 mode selected in step 2.
4. Refer to the NA-3 operators manual for instruc­tions on how to use the NA-3 in conjunction with the DC-600.
5. Follow the following guidelines for good arc strik­ing detailed below for each welding mode.
GOOD ARC STRIKING GUIDELINES FOR THE NA­3 WITH THE DC-600 IN THE CV INNERSHIELD, CV SUBMERGED ARC OR CC STICK WELDING MODES.
1. Cut the electrode to a sharp point.
2. Set the NA-3 Open Circuit Voltage Control to the same dial setting as the Arc Voltage Control. If this is a new welding procedure, a good starting point is to set the Open Circuit Voltage Control to # 6.
NOTE: The open circuit voltage of the DC-600 varies from approximately 16 volts to 56 volts in the CV INNERSHIELD or CV SUBMERGED ARC modes. The open circuit volt­age is constant in the CC STICK mode.
3. Run a test weld. Set proper current, voltage, and travel speed.
a. For the best starting performance, the NA-
3 Open Circuit Voltage Control and Voltage Control setting should be the same. Set the Inch Speed Control for the slowest inch speed possible.
b. To adjust the Open Circuit Voltage Control to
get the best starting performance, make repeated starts observing the NA-3 voltmeter.
When the voltmeter pointer swings smoothly up to the desired arc voltage, without undershooting or overshooting the desired arc voltage, the Open Circuit Voltage Control is set properly.
If the voltmeter pointer overshoots the desired voltage and then returns back to the desired volt­age, the Open Circuit Voltage Control is set too high. This can result in a bad start where the wire tends to "Blast off."
If the voltmeter pointer hesitates before coming up to the desired voltage, the Open Circuit Voltage Control is set too low. This can cause the elec­trode to stub.
4. Start and make the weld.
Following are some basic arc striking techniques that apply to all wire feed processes. Using these proce­dures should provide trouble-free starting. These pro­cedures apply to single, solid wires and Innershield wires.
DC-600 RED-D-ARC
a. Cold starts. For cold starts, be sure the work
piece is clean and the electrode makes posi­tive contact with the work piece.
b. Hot "On the Fly" starts. For hot starts, travel
should begin before the wire contacts the work piece.

ARC STRIKING WITH DC-600 AND THE NA-3 START BOARD
When electrical strikeouts exceed 1 3/4” (44.4mm) an NA-3 Start Board may be required to improve arc striking.
When the NA-3 Start Board is used to improve arc striking, use the following procedures:
1. Set start time at 0.
2. Set NA-3 start current and start voltage at mid­range.
3. Set the NA-3 output current and voltage to the proper settings for the welding procedure to be used.
4. Turn the Start Board Timer to maximum.
5. Set Start Board current and voltage control.
a. Set the Start Board current control to 1 1/2
dial numbers below that set on the NA-3 cur­rent control.
If the voltmeter pointer overshoots the desired voltage and then returns back to the desired volt­age, the Open Circuit Voltage Control is set too high. This can result in a bad start where the wire tends to "Blast off."
If the voltmeter pointer hesitates before coming up to the desired voltage, the Open Circuit Voltage Control is set too low. This can cause the elec­trode to stub.
c. Set NA-3 Start Board current and voltage as
close to the welding procedure current and voltage as possible.
NOTE: The Start Board current and voltage should be as close as possible to the welding pro­cedure current and voltage, while still getting sat­isfactory starts.
d. Set the start time to as low a time as possible
while still getting satisfactory starts.
7. Start and make the weld.
b. Set the Start Board voltage control equal with
the NA-3 voltage control setting.
NOTE: These Start Board current and voltage settings result in a start up current that is lower than the NA-3 current setting and approximately equal with the NA-3 voltage setting for the desired welding procedure.
6. Establish the correct arc striking procedure with the NA-3 Start Board timer set at maximum.
a. For the best starting performance, the NA-3
Open Circuit Voltage Control and Voltage Control setting should be the same. Set the Inch Speed Control for the slowest inch speed possible.
b. To adjust the Open Circuit Voltage Control to
get the best starting performance, make repeated starts observing the NA-3 voltmeter.
When the voltmeter pointer swings smoothly up to the desired arc voltage, without undershooting or overshooting the desired arc voltage, the Open Circuit Voltage Control is set properly.

SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK CAN KILL.
• Only qualified personnel should perform this mainte­nance.
• Turn the input power OFF at the disconnect switch or fuse box before working on this equipment.
Do not touch electrically hot parts.
------------------------------------------------------------------------
ROUTINE AND PERIODIC MAINTENANCE
1. Disconnect input AC power supply lines to the machine before performing periodic maintenance, tightening, cleaning, or replacing parts.
Perform the following daily:
1. Check that no combustible materials are in the welding or cutting area or around the machine.
TESTING THE GFCI RECEPTACLE
1. Turn the welder ON. Press the reset button fully. Plug a lamp or radio into the GFCI (and leave it plugged in) to verify that the power is ON. If there is no power, go to Troubleshooting Section.
2. Press the TEST button in order to trip the device. This should stop the flow of electricity, making the lamp or radio shut OFF. Note that the REST button will pop out. If the power stays on, go to Troubleshooting Section. If the power goes OFF, the GFCI receptacle is working properly. To restore power, press the RESET button.
3. Press the TEST button (then RESET button) every month to assure proper operation.
NOTE:
The GFCI receptacle is in a 115v circuit where the neutral is floating with respect to ground. Consequently if a GFCI tester is plugged into the GFCI receptacle, the tester will show that there is an “open ground”. The indication of an”open ground” is normal and the GFCI will function properly in the event of a ground fault current as the GFCI is designed to do.
2. Remove any debris, dust, dirt, or materials that could block the air flow to the machine for cooling.
3. Inspect the electrode cables for any slits or punctures in the cable jacket, or any condition that would affect the proper operation of the machine.
Perform Periodically:
Clean the inside of the machine with low pressure air stream. Clean the following parts. When using air, be careful to adequately protect your eyes.
Main transformer and choke.
Electrode and work cable connections.
SCR rectifier bridge and heat sink fins.
Control board.
Firing board.
Fan Assembly. NOTE: The fan motor has sealed bearings which require no maintenance.

PC BOARD TROUBLESHOOTING PROCEDURES
E-2
WARNING
ELECTRIC SHOCK can kill.
Have an electrician install and ser­vice this equipment. Turn the input power OFF at the fuse box before working on equipment. Do not touch electrically hot parts.
CAUTION: Sometimes machine failures appear to be
due to PC board failures. These problems can some­times be traced to poor electrical connections. To avoid problems when troubleshooting and replacing PC boards, please use the following procedure:
1. Determine to the best of your technical ability that the PC board is the most likely component causing the failure symptom.
2. Check for loose connections at the PC board to assure that the PC board is properly connected.
3. If the problem persists, replace the suspect PC board using standard practices to avoid static elec­trical damage and electrical shock. Read the warn­ing inside the static resistant bag and perform the following procedures:
P.C. Board can be damaged by static electricity.
• Remove your bodyʼs static charge before opening the static-shielding bag. Wear an anti-static wrist strap. For safety, use a 1 Meg ohm
ATTENTION Static-Sensitive Devices Handle only at Static-Safe Workstations
Reusable Container Do Not Destroy
resistive cord connected to a grounded part of the equip­ment frame.
• If you donʼt have a wrist strap, touch an unpainted, ground­ed, part of the equipment frame. Keep touching the frame to prevent static build­up. Be sure not to touch any electrically live parts at the same time.
• Remove the P.C. Board from the static-shielding bag and place it directly into the equipment. Donʼt set the P.C. Board on or near paper, plastic or cloth which could have a static charge. If the P.C. Board canʼt be installed immediately, put it back in the static-shield­ing bag.
• If the P.C. Board uses protective shorting jumpers, donʼt remove them until installation is complete.
• If you return a P.C. Board for credit, it must be in the static-shielding bag. This will prevent further damage and allow proper failure analysis.
4. Test the machine to determine if the failure symp-
tom has been corrected by the replacement PC board.
NOTE: It is desirable to have a spare (known good) PC board available for PC board troubleshooting.
NOTE: Allow the machine to heat up so that all electri­cal components can reach their operating tempera­ture.
5. Remove the replacement PC board and substitute it
with the original PC board to recreate the original problem.
a. If the original problem does not reappear by sub-
stituting the original board, then the PC board was not the problem. Continue to look for bad connec­tions in the control wiring harness, junction blocks, and terminal strips.
b. If the original problem is recreated by the substitu-
tion of the original board, then the PC board was the problem. Reinstall the replacement PC board and test the machine.
6. Always indicate that this procedure was
followed when warranty reports are to be submit­ted.
NOTE: Following this procedure and writing on the warranty report, “INSTALLED AND SWITCHED PC BOARDS TO VERIFY PROBLEM,” will help avoid denial of legitimate PC board warranty claims.
• Tools which come in contact with the P.C. Board must be either conductive, anti-static or static-dissi­pative.

PROBLEMS (SYMPTOMS)
Machine shuts off (input contactor drops out) when the welder output terminals are made electrically "hot". (#2 to #4 closure at terminal strip.) or OUTPUT TERMINALS switch is in ON position.
The DC600 will NOT shut off when the Power Switch is turned to OFF.
POSSIBLE CAUSE
OUTPUT PROBLEMS
1. Remove all welding cables and
control cables from the DC-600. Jumper #2 to #4 at the terminal strip or set OUTPUT TERMI­NALS switch to ON position. If the machine does NOT shut off and normal open circuit voltage is present at the welder output terminals the problem is exter­nal to the DC-600. Either the remote leads #75, #76 or #77 are grounded to the negative output cable or there is a short on the welding output terminals.
2. If the machine still shuts off
when all control and welding cables are removed then the problem is internal to the DC-
600.
1. Contact your local Authorized
Field Service Facility.
RECOMMENDED COURSE OF ACTION
If all recommended possible areas of misadjustment have been checked and the problem persists,
Contact your local Authorized Field Service Facility.
The weld output terminals are always electrically "hot".
1. Remove any external leads
hooked to #2 and #4 on the ter­minal strip or any connections to the 14 pin MS connector. Set OUTPUT TERMINALS switch to the OFF position. If the prob­lem disappears the fault is in the control cable or wire feeder.
2. If some open circuit voltage is
present (over 3VDC.) after per­forming Step #1. then the prob­lem is within the DC-600.
CAUTION
If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your
