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

3. If voltage is present at J3-9, check
for battery voltage at J3-8 (lead
#224A). If voltage is not present,
replace the PC board.
4. If voltage is present at J3-8,
check for battery voltage at J1-
9 (lead #224). If voltage is not
present, check leads 224 and
224A. Check the positive
terminal connections at the
hour meter.
5. Check that the PC board is
properly grounded, pin J1-2
(lead GND-G).
6. Perform the rotor flashing,
voltage, and resistance
tests.
7. Perform the stator resistance
and voltage tests.
There is no weld output, or weld
voltage drops dramatically when
trying to strike an arc. The
115/230 VAC auxiliary output is
normal; engine operates
normally.
1. Check weld cables,
connections, work clamps, and
electrode holder.
2. With engine running at high
idle, and output control set to
maximum, check the DC
voltage at the weld output
terminals. It should measure
70 to 80 Volts RMS.
1. Check for loose or damaged
connections between the
output terminals, the choke,
the rectifier, the rector, and the
stator. See wiring diagram.
2. With engine running at high
idle, and output control set to
maximum, check for about 63
VAC from each of the two
stator weld windings (W1 to
W2) and (W3 to W4). See
wiring diagram. If voltage is
not present for either test, the
stator is probably defective.
3. With the engine still running,
check for about 63 VAC at
W1A to W2 and from W3A to
W4. If voltage is not present
for either test, the reactor may
be defective.
