COURSE OF ACTION
No weld output - auxiliary power
(230 - 115 VAC) operates normally -
engine runs normally.
1. Check continuity (zero ohms) of
lead W1A (black) from output ter-
minal to reactor (L1). See the
Wiring Diagram.
2. Check continuity (zero ohms) of
lead W2 (black) from output
terminal to stator winding. See
the Wiring Diagram.
3. Check continuity (zero ohms) of
lead W1A (black) from reactor
(L1) to stator winding. See the
Wiring Diagram.
4. Check reactor (L1) for continuity
of winding. See the Wiring Dia -
gram.
5. Check the stator for continuity of
winding. See the Wiring Dia -
gram.
6. Make certain the reactor and/or
stator are NOT grounded. Mini -
mum acceptable resistance to
ground is 500 K-ohms.
1. Check the open circuit voltage
(OCV) at the welder output termi-
nals. If OCV is okay, go to Step
2; below.
If OCV is not present at the welder
output terminals, contact your
local Lincoln Electric Authorized
Field Service Facility.
2. Check the welding cables,
clamps and electrode holder for
loose or broken connections.
