COURSE OF ACTION
If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely,
contact the Lincoln Electric Service Department for technical troubleshooting assistance before you proceed.
Call 1-888-935-3877.
CAUTION
Major Physical or Electrical
Damage is Evident
1. Contact your local Lincoln
Electric Authorized Field Service
Facility.
1. Contact The Lincoln Electric
Service Dept. 1-888-935-3877
Machine is dead - No output, no fan,
no display.
1. Check for blown or missing
fuses in the input line.
2. Check the three phase input line
voltage at the machine. Input
voltage must match the rating
plate and the reconnect panel.
1. Check input line switch may be
faulty. Check or replace.
2. Remove the input power and
check for loose or broken leads
at the reconnect panel and at
the main transformer primary
coils.
3. Perform
Main Transformer
Test.
The machine has no output. The
fan runs and the display lights.
1. Make sure the thermal light is
NOT lit (earlier codes the pilot
light is NOT blinking). If either
condition exists, then the
machine may be overheated.
2. If an error message is displayed,
see
Explanation of Error
Messages.
3. Make sure the three phase input
voltage matches the reconnect
panel configuration and that all
three phases are applied to the
machine.
4. Place a jumper wire from pin “C”
to pin “D” at the 14 pin amphenol
connection. If output is restored,
then check the wirefeeder and
associated control cable.
1. Check the trigger circuit (#2 and
#4) for continuity from the 14 pin
amphenol to the control board.
See wiring diagram.
2. If the machine has output in
machine control but not in
remote control, check the
remote switch (S4). Check the
wiring to the control board and to
the 14 pin amphenol.
3. Swap any two of the three phase
input. If output returns, the Line
Switch is faulty.
4. Check for loose or faulty con-
nections at the output terminals
and the heavy current carrying
leads.
5. The control board may be faulty.
Replace.
