contact the Lincoln Electric Service Department for technical troubleshooting assistance before you proceed.
Call 1-888-935-3877.
CAUTION
1. Check the welding cables for
loose or faulty connections.
2. The welding cables may be
excessively long or coiled.
3. Check the main DC generator
brushes for good commutation
and alignment. Contact the
Lincoln Electric Service Dept. 1-
888-935-3877.
1. The engine RPM may be low.
If necessary perform the
Engine Throttle Adjustment
Test. (PERKINS code 10929
ONLY)
2. Perform the DC Exciter Test.
3. Check the fine current control
field rheostat for resistance
and proper operation. Normal
resistance is 64 ohms. Check
associated wires for loose or
faulty connections. See the
Wiring Diagram.
4. Check the current range
selector switch and contacts
for proper operation.
5. Perform the Main Generator
Shunt Field Winding Test.
6. The main armature may be
faulty. Check for grounds.
The actual welding current is
much greater than is indicated
on the dials.
1. The engine operating speed
may be too high. If necessary
perform the Engine Throttle
Adjustment Test. (PERKINS
code 10929 ONLY)
2. While the machine is loaded,
check the series coils for signs
of “arcing.” This condition
could point to shorted turns in
the series coils.
