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.

CAUTION
The machine has low output and no
control. The fan runs and the dis-
play is lit.
1. Place the remote switch in
machine control. If normal out-
put is restored then the remote
control unit may be faulty. Check
or replace.
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.
1. If the machine has normal out-
put 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.
2. If the machine has low output
in machine control check the
output control (R2) and associ-
ated leads.
3. Check the feedback leads from
the shunt and the output termi-
nals to the control board. See
wiring diagram.
4. Check the latching resistor
(R1) and the associated leads.
See wiring diagram.
5. Check for loose or faulty con-
nections at the output terminals
and the heavy current carrying
leads.
6. The control board may be
faulty. Replace.
