are known to the State of California to cause can­cer, birth defects, and other reproductive harm.

The Above For Diesel Engines

ARC WELDING CAN BE HAZARDOUS. PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH.
KEEP CHILDREN AWAY. PACEMAKER WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE OPERATING.

Read and understand the following safety highlights. For additional safety information, it is strongly recommended that you
purchase a copy of “Safety in Welding & Cutting - ANSI Standard Z49.1” from the American Welding Society, P.O. Box
351040, Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available
from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199.

BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.

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.

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.

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

if damaged.

7.a. Use only compressed gas cylinders
containing the correct shielding gas for the
process used and properly operating
regulators designed for the gas and

pressure used. All hoses, fittings, etc. should be suitable for
the application and maintained in good condition.

7.b. Always keep cylinders in an upright position securely
chained to an undercarriage or fixed support.

7.c. Cylinders should be located:

• Away from areas where they may be struck or subjected to

physical damage.

• A safe distance from arc welding or cutting operations and

any other source of heat, sparks, or flame.

7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.

7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.

7.f. Valve protection caps should always be in place and hand
tight except when the cylinder is in use or connected for
use.

7.g. Read and follow the instructions on compressed gas
cylinders, associated equipment, and CGA publication P-l,
“Precautions for Safe Handling of Compressed Gases in
Cylinders,” available from the Compressed Gas Association
1235 Jefferson Davis Highway, Arlington, VA 22202.

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.

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.

• The Multi-Source power supply should not be used

if the green Safe Output light is not lit. The machine
is designed to open its input contactor if output volt­age peaks exceed the limits set by certain approval
agencies. If the Safe Output light is on, the output
voltage is within it designed operating range.

-------------------------------------------------------------------

LOCATION

Place the power supply where clean cooling air can
freely circulate in through the front louvers and out
through the rear louvers. Dirt, dust or any foreign
material that can be drawn into the welder should be
kept at a minimum. Failure to observe these precau­tions can result in excessive operating temperatures
and nuisance shut-downs.

STACKING

WARNING

FALLING EQUIPMENT can cause

injury.

• Two Multi-Source machines can be
stacked.

• Lift only with equipment of adequate
lifting capacity.

• Be sure machine is stable when lifting.

• Do not stack more than two high.

• Do not stack the Multi-Source on top of any other
machine.

---------------------------------------------------------------------

• Follow these guidelines when stacking:

INPUT AND GROUNDING
CONNETIONS

Note: A qualified electrician should connect the

input power supply leads.

Input conductor is brought into the machine input box
area through a hole in the rear panel sized to accom­modate 2" (trade size) conduit and fittings. This is
more than adequate for the largest conductors
required.

Conductors must be lugged to attach to the three 3/8"
studs on the input reconnect panel and the 5/16"
ground stud marked with the symbol . The input
voltage supplied determines the position required for
the reconnect panel jumper. The three ranges on the
standard machine are 380-415, 440-460 and 550-575.
The machine is rated for 50 and 60 Hz operation. See
the Input Connection Diagram located on the inside of
Case Back Input Access Door.

The conductor and fuse sizes in the Technical
Specification Section (A-1), are per the 1999 National
Electrical Code. The sizes are in American Wire
Gauge (and the next largest standard metric size in

mm2). National and local codes must be consulted
before connecting a machine.

Protect the input circuit with the super lag fuses or
delay type circuit breakers listed in the Technical
Specification Section (A-1). (They are also called
inverse time or thermal / magnetic circuit breakers.)

Use of fuses or circuit breakers with a lower amp rat­ing than recommended can result in nuisance tripping
caused by inrush current even when machine is not
being used for welding at high output currents.

Machines may be paralleled for increased output.
The S20428 Paralleling Kit permits paralleling of two
Multi-Source power supplies for supplying currents of
up to 1000 amps, 100% duty cycle.

1. Select a firm, level surface capable of supporting
the total weight of up to two machines (1984
pounds/901kilograms).

2. Set the bottom machine in place.

3. Stack the second machine on top of it by aligning
the two holes in the base rails on the second
machine with the two pins on top at the front of the
bottom machine.

Note: The machines must be stacked with the Case

Front of each machine flush with each other.

MULTI-SOURCE

A-3

INSTALLATION

OUTPUT CABLES, CONNECTIONS
AND LIMITATIONS

The Multi-Source has two parallel connected output
studs for positive and negative connections. Each one
is rated to carry the full output current. For its maxi­mum rated current at 100% duty cycle a minimum size
of 4/0 AWG is recommended.

Connection of Electrode and Work Leads to
Output terminals.

1. Set the POWER ON/OFF Toggle Switch to OFF.

2. Raise the hinged cover protecting the output termi­nals.

3. Insert the electrode lead up through the elliptical
hole in the machine base below the positive output
terminal. Pull through enough cable to reach the
output terminal.

4. Connect electrode lead to the terminal .

5. Tighten the output terminal nut with a wrench.

6. Connect the work lead to the negative output termi­nal following steps 3-5.

7. Lower the cover to protect the output terminals.

RECOMMENDED EQUIPMENT AND
PROCESSES

The only recommended use for the Multi-Source is to
power the Multi-Weld welders. It is conceivable that
the machine could be used as a constant voltage DC
power supply up to its rating of 40,000 watts (36,000
watts on 50Hz) output. Its output is stable with a wide
range of inductive, resistive and capacitive loads but
each application would have to be tested. The output
is peak voltage regulated and at light resistive loads
(maximum ripple) the average voltage deviates from
peak voltage the most.

MULTI-SOURCE

The Multi-Source 40kW (36kW on 50Hz) 80VDC buss
power source (K1752-1) is recommended for use in
the Multi-Weld system. The number of Multi-Weld
Converters that may be connected to a single Multi­Source Power Source is determined by the following
formula:

Power Source (Volts x Amps) capacity > 1.1 x Sum

of Converters’ (Volts x Amps) arcs

A-3

RECOMMENDED EQUIPMENT / INTERFACE

The Multi-Weld 350 (K1752-1) is the recommended
means by which to control the Multi-Source power
supply. Connections between Multi-Source and Multi­Weld may be easily made using Twist-Mate male and
female connectors and the K1736-1 Distribution Box.
The Multi-Weld 350 has multi-process capability and
may be used manual and semi-automatic processes.
When a wire feeder is required an LN-25 (K449) is
recommended.

EQUIPMENT LIMITATIONS

The number of Multi-Weld 350s, the procedures used
and the combined duty cycle of the arcs are only limit­ed by the 40,000 (36,000 watts on 50Hz) watt rating of
the Multi-Source supply. The machine is IP-23S rated
and is designed for outdoor applications.

DISTRIBUTION BOX

The Multi-Weld Distribution Box (K1736-1) is avail­able for interconnection of the Multi-System using the
same "pig-tail" connection method provided with the
Multi-Weld 350 converter. Six cable strain-relief ports
are provided for connection of up to (12) cables for
distribution or "daisy-chain" inter-connection to other
boxes. Four "pig-tail" leads (see below) are included
with the Box.

"PIG-TAIL" LEADS AND CONNECTORS

Accessory "pig-tail" leads and Twist-Mate connectors
are available from Lincoln for extra connections to the
Muli-Weld 350 or the Distribution Box:

SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or
electrode with skin or wet clothing.

• Insulate yourself from work and
ground.

• Always wear dry insulating gloves.

------------------------------------------------------------------------

FUMES AND GASES can be danger­ous.

• Keep your head out of fumes.

• Use ventilation or exhaust to remove

fumes from breathing zone.

------------------------------------------------------------------------

WELDING SPARKS can cause fire or
explosion.

• Keep flammable material away.

• Do not weld on closed containers.

------------------------------------------------------------------------

ARC RAYS can burn eyes and skin.

• Wear eye, ear and body
protection.

Other indicator lights include the amber Thermal light
that signals when the long term output current limit
has been exceeded. This limit is determined by a ther­mostat sensing the temperature of the negative output
lead from the secondary coils. The white Power light
indicates when the Control board is energized. The
three lights are high intensity LEDs for improved visi­bility in daylight.

The Output Power display uses high intensity LEDs to
indicate the percentage of full rated output the
machine is supplying.

Two additional thermostats protect the machine in the
case of fan failure or blocked air flow. The SCR heat
sink thermostat responds first to loss of air flow at nor­mal output loads. This thermostat will disable the
machine output. The transformer iron rear thermostat
senses that the lamination (and thus the coil insula­tion) is over heating (which can happen even if the
output is disabled). This thermostat will interrupt
power to the Control board causing the input contactor
to open until the iron cools.

The only user controls are an on-off toggle Power
switch that energizes the machine and a 10 A circuit
breaker protecting the fan auxiliary against short cir­cuits.

See additional warning information at

front of this operator’s manual.

GENERAL DESCRIPTION

The Multi-Source is designed to supply power to the
Multi-Weld welders. It has a wide range three phase
AC input and can be operated on 50 or 60 Hz. The
Multi-Source output peak voltage regulates against
wide changes in output loading and input line voltage
variations to supply a consistently stable voltage high
enough to allow the Multi-Welds to provide good man­ual electrode capability.

Primary input voltage taps are selected by a single
movable link on the reconnect panel. Main trans­former auxiliary windings power the firing circuit and
fan motor. The control auxiliary transformer has a sin­gle, wide range primary and is not reconnectable.

The Fan As Needed feature is activated by an output
current of 20 Adc or a thermostat on the main trans­former iron.

DESIGN FEATURES - ALL MODELS

SPECIFICATIONS, DESIGN FEATURES
AND ADVANTAGES

Case parts are predominantly stainless steel, the PC
boards are potted in trays, the controls are sealed, all
machine coils are copper and the whole transformer is
varnish dipped to maximize environmental withstand
capability. The coils are all conservatively rated for
long life.

The Multi-Source output regulates against wide
changes in output loading and input line voltage varia­tions to supply a consistently stable voltage high
enough to allow the Multi-Welds to provide good man­ual electrode capability.

An independent safety circuit on the Control board
monitors the voltage peaks and opens the input con­tactor if the limit is exceeded. The green Safe Output
light indicates when the machine output voltage is
within the safe operating range.

MACHINE CALIBRATION
SPECIFICATION

The Multi-Source digital display is controlled by a cur­rent sensing circuit on the Control board. The display
reads 100 when machine output is a little over 40 kW.
To recalibrate the display, the machine output may
loaded with Multi-Weld welders or resistive grids or a
combination of both to obtain an output of 533 Adc as
read by a calibrated standard ammeter. Trimmer
resistor R49 may be adjusted to cause the display to

read 100.

ROUTINE MAINTENANCE

The Multi-Source needs no routine maintenance. The
fan bearings are sealed units.

PERIODIC MAINTENANCE

Periodically the machine may be cleaned with low
pressure compressed air to insure that all cooling pas­sages are open and that conductive foreign material

has not built up inside.

GUIDE - FIRING P.C. BOARD

1. LEDs 1 through 9 must be lit when the Multi-Source
is turned on and the Control board is sending an
enable signal to the Firing board (pin 7 in P8 is low
in reference to common at pin 12 in P5).

2. LEDs 7, 8, and 9 indicate AC power being supplied
to the P.C. board from auxiliary windings on the
main transformer (T1). If a LED is not on, turn the
machine off and unplug P8 from the firing board.
Turn the machine back on and check the following
voltages:

3. If all voltages are present, turn power off, and plug
P5 back into J5. Turn power back on. If LEDs 7, 8
or 9 are still not lit, replace Firing PCB.

4. If voltages were not present, check the circuit back
through the external dropping resistors to the auxil­iary windings for a possible open resistor or wire.

E-4

5. LEDs 1 through 6 indicate gate signals are being
sent to the main SCRs 1 through 6 respectively. If
LED2 on the Control board is bright, along with
LEDs 7, 8, and 9 on Firing board, and LEDs 1
through 6 are unequal in brightness, check to make
sure lead 231 between Control board and Firing
board is not broken. (If lead 231 is removed while
the machine output is at open circuit, the output
voltage peaks may be unregulated and cause the
over-voltage protection circuit to open the input
contactor. The over-voltage protection circuit may
disabled by disconnecting lead 222D at the nega­tive output stud or at pin 1 of P2. NOTE: The
machine may not be used for welding with the pro­tection circuit disabled.

6. If one or more of LEDs 1 through 6 are off, LEDs 7,
8, and 9 are on and the voltage on lead 231 from
the Control board (pin 13, P5 to pin 12, P5) is 3 to

PC BOARD TROUBLESHOOTING
GUIDE - CONTROL P.C. BOARD

1. The white Power light on the machine control panel
indicates that the Control board power supply is
being supplied by rectified secondary voltage from
the Control transformer (T2) by way of the Power
switch and transformer iron rear thermostat.

2. LED1 indicates machine output voltage. At normal
output voltages, LED1 will be brightly lit.

3. LED2 indicates the level of the control signal to the
Firing board. The brightness of LED2 is inversely
proportional to machine output because the control
signal increases as the machine output decreases.

4. LED3 lights when the current amplifier senses an
output current over about 10 amps and sends a sig­nal to turn the cooling fan on. If LED3 is on but the
fan is not , there could be a problem with the fan
motor or the fan motor drive circuit (see LED6).

5. LED4 says that some signal, either thermostat, out­put current or output over-current is calling for the
fan to operate.

7. LED6 indicates that the input to the fan motor opto
triac driver has been energized. LED6 should be on
as long as the fan motor runs. LED6 and the fan
motor will be on for about 5 minutes after LED4
goes off.

8. LED7 will light when the shorted SCR circuit acti­vates. A positive voltage on the negative output
stud (AC instead of DC on the output studs) will
activate a circuit causing the input contactor to
open. This circuit is active only when the enable
signal to the Firing board is high (the output is off).
The contactor will remain open (and the white

Power light will remain on) until the Power switch is
turned off (or the input power to the machine is oth­erwise removed) for about 1 second and then
turned on again.

9. The green Safe Output light on the control panel
when the machine output voltage is present and
safe. It lights when the machine output is between
40 Vdc and 113 volts peak.

10. The yellow Thermal light on the front panel lights

when the open thermostat signal is sent to the fan
control and output disable circuits.

6. LED5 tells us that the current signal from the shunt
is too high. If LED5 is lit for 5-8 seconds, the enable
signal to the Firing board is made high to shut off
the output SCRs. In the case of a short duration
current overload, LED5 may only be briefly lit
because, in normal operation, the machine output
immediately goes to zero. Once disabled, the out­put will remain off for about 75 seconds.

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your

Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed.
