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
No weld output, the auxiliary power
(230-115VAC) is operating normal-
ly. Engine runs normally.
1. Check the open circuit voltage
(OCV) at the welder output termi-
nals, engine at high idle (3650
RPM). Normal maximum is 73 to
80VAC. Normal DC maximum is
67 to 72VDC. If the OCV is OK
then proceed to Step #2. If the
OCV is not present at the welder
output terminals, contact your
local Lincoln Authorized Field
Service Facility.
2. Check the welding cables,
clamps and electrode holder for
loose or broken connections.
1. Disconnect lead W1 from the
Output Bridge (D1) and check
for the presence of 80VAC from
lead W1 to lead W2 on the main
stator winding. See wiring dia-
gram. If the AC voltage is NOT
present, the winding in the sta-
tor may be faulty. Check the
winding for continuity and test to
be sure it is NOT grounded to
the stator iron. Replace if nec-
essary. If the correct AC volt-
age is present, proceed to step
#2.
2. Check the Reactor, Range
Switch (S1) and associated
wires for loose or faulty connec-
tions. Check the reactor wind-
ing for continuity and test to be
sure it is NOT grounded to the
reactor iron.
3. Check the Choke (L1) and
associated wires for loose or
faulty connections. Check the
choke winding for continuity and
test to be sure it is NOT ground-
ed to the choke iron.
4. Check the weld output terminals
and associated wires for loose
or faulty connections.
5. Perform the Output Bridge
Test.
