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
There is no auxiliary voltage,
weld output is normal.
Check that the auxiliary power
circuit breakers are not tripped.
If the machine is equipped with a
ground fault circuit interrupter
(GFCI), it may be tripped or
defective.
NOTE: GFCIs will not reliably
reset, unless engine is operating
at high idle RPM.
Check all leads and cables for
damaged or poor connections.
Check for auxiliary voltage at the
receptacle input terminals, if
normal voltage is present,
replace receptacle.
Check for auxiliary voltage at the
connections closest to the
exciter stator windings. See
wiring diagram.
• If normal voltage is present,
check the wiring and circuit
breakers between the test
points and the receptacle.
Repair or replace any
defective parts or wiring.
• If normal voltage is not
present, check for damaged
conductors between the test
points and the winding. If the
conductors are good, the
stator is defective.
