contact the Lincoln Electric Service Department for technical troubleshooting assistance before you proceed.
Call 1-888-935-3877.
CAUTION

4. With the engine still running,
check for about 70 to 80 VDC
at the output rectifier positive
and negative terminal. If
voltage is not present, the
rectifier is probably faulty.
5. If the is voltage at the rectifier
output, but not at the weld
terminals, the choke may be
open.
No 115/230 VAC auxiliary output –
Weld output is normal and engine
operates normally.
1. Check for faulty extension
cords, tools, lights, etc. Plug in
a known working device.
2. Check for tripped circuit
breakers.
3. If the Outback® has optional
GFCI receptacles, try resetting
them.
NOTE: Engine must be running at
high idle RPM or the GFCI
receptacles will not reset.
1. Check for AC voltage at the
back of the receptacles. If
voltage is present at the back
of the receptacles but the
receptacles still will not
function, replace the
receptacle.
2. Check for 120 VAC from lead
#5 to leads #3 and #6 at the
circuit breakers. See wiring
diagram. If 120 VAC is
present, one or more circuit
breakers may be defective.
3. If AC voltage is not detected in
step 2 above, check leads
between the test points and the
stator winding. If the leads are
good, the stator is likely
defective.
Low weld and auxiliary output,
the engine operates normally.
1. The output control may be set
too low.
2. Engine RPM may be low.
3. The battery may be faulty.
1. Perform the Engine RPM
adjustment procedure.
2. The brushes and slip rings may
be worn or faulty. Perform the
brush and slip ring service
procedure.
3. Perform the battery and
charging system tests.
4. Perform the rotor and stator
voltage tests.
