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.

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).

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.

amp rating than recommended. This can result in “nui­sance” tripping caused by inrush current even when
machine is not being used for welding at high output
currents.

Use input and grounding wire sizes that meet local
electrical codes or see the Technical Specifications
page in this manual.

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

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

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.

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.
