The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.

The Above For Gasoline Engines

FOR ENGINE powered equipment.

1.a. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running.

____________________________________________________

1.b. Operate engines in open, well-ventilated areas or vent the engine exhaust fumes outdoors.

____________________________________________________

1.c. Do not add the fuel near an open flame welding arc or when the engine is running. Stop the engine and allow it to cool before refueling to prevent spilled fuel from vaporizing on contact with hot engine parts and igniting. Do not spill fuel when filling tank. If fuel is spilled, wipe it up and do not start engine until fumes have been eliminated.

____________________________________________________

1.d. Keep all equipment safety guards, covers and devices in position and in good repair.Keep hands, hair, clothing and tools away from V-belts, gears, fans and all other moving parts when starting, operating or repairing equipment.

____________________________________________________

1.e. In some cases it may be necessary to remove safety

guards to perform required maintenance. Remove guards only when necessary and replace them when the maintenance requiring their removal is complete. Always use the greatest care when working near moving parts.

___________________________________________________

1.f. Do not put your hands near the engine fan. Do not attempt to override the governor or idler by pushing on the throttle control rods while the engine is running.

1.h. To avoid scalding, do not remove the radiator pressure cap when the engine is hot.

ELECTRIC AND MAGNETIC FIELDS may 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, and welders having a pacemaker should consult their physician before welding.

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

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

2.d.1.

Route the electrode and work cables together - Secure them 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 and

work cables. If the electrode cable is on your right side, the work cable should also be on your right side.

___________________________________________________

1.g. To prevent accidentally starting gasoline engines while turning the engine or welding generator during maintenance work, disconnect the spark plug wires, distributor cap or magneto wire as appropriate.

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

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

SAFETY

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 skin 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 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.

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 ventilation and/or exhaust at the arc to keep

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.

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.

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

5.b.

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.c. 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.

5.d. Read and understand the manufacturer’s instructions for this

equipment and the consumables to be used, including the material safety data sheet (MSDS) and follow your employer’s safety practices. MSDS forms are available from your welding distributor or from the manufacturer.

5.e. Also see item 1.b.

WELDING SPARKS can cause fire or explosion.

6.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

the welding sparks from starting a fire.

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.

6.h. Also see item 1.c.

Remember that welding sparks and hot

SAFETY

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 L’Arc

1. Protegez-vous contre la secousse électrique:

a. Les circuits à l’électrode 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 s’isoler 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 l’eau 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 s’applicuent aussi au pistolet de soudage.

zones où l’on pique le laitier.

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

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

8. S’assurer que la masse est connectée le plus prés possible de la zone de travail qu’il est pratique de le faire. Si on place la masse sur la charpente de la construction ou d’autres 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 d’incendie ou d’echauffement des chaines et des câbles 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 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 d’opérations de dégraissage, nettoyage ou pistolage. La chaleur ou les rayons de l’arc 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.

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 n’importe quelle partie du 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 approprié

ainsi qu’un verre blanc afin de se protéger les yeux du rayonnement de l’arc et des projections quand on soude ou quand on regarde l’arc.

b. Porter des vêtements convenables afin de protéger la

peau de soudeur et des aides contre le rayonnement de l‘arc.

c. Protéger l’autre personnel travaillant à proximité au

soudage à l’aide d’écrans appropriés et non-inflammables.

4. Des gouttes de laitier en fusion sont émises de l’arc de soudage. Se protéger avec des vêtements de protection libres de l’huile, 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

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 l’électricité 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, I’installation et l’entretien du poste seront effectués par un électricien qualifié.

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

4. Garder tous les couvercles et dispositifs de sûreté à leur place.

CONTROLS AND SETTINGS

All operator controls and adjustments are located on the Case Front Assembly of the DC-600. See Figure B.1 for the location of each control.

DC-600

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 machine’s 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 machine’s red 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 machine’s 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-600’s 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 machine’s 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-600’s 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).

6. Mode Switch

This switch allows for selecting the welding process to be used:

CC STICK-for SMAW and AAC CV SUBMERGED ARC- for SAW CV INNERSHIELD- for FCAW and GMAW

7. 115VAC Duplex 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 duplex 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 red 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 red 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.

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 red 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 red 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 (AAC) / 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.

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.

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.

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.

1. Cut the electrode to a sharp point.

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.

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.

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.

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.

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.

a. Remove your body’ s static

charge before opening the static-shielding bag. Wear an anti-static wrist strap. For

ATTENTION Static-Sensitive Devices Handle only at Static-Safe Workstations

Reusable Container Do Not Destroy

c. Tools which come in contact with the P.C. Board

must be either conductive, anti-static or static-dissipative.

safety, use a 1 Meg ohm resistive cord connected to a grounded part of the equipment frame.

b. If you don’t 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.

d. Remove the P.C. Board from the static-shielding

bag and place it directly into the equipment. Don’t set the P.C. Board on or near paper, plastic or cloth which could have a static charge. If the P.C. Board can’t be installed immediately, put it back in the static-shielding bag.

e. If the P.C. Board uses protective shorting jumpers,

don’t remove them until installation is complete.

f. 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 symptom 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 elec-

trical 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 substi-

tution 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.
