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
Engine will not idle down to low
speed. Machine has normal weld
output and auxiliary power.
1. Make sure the Idler Switch (S4)
is in the “Auto” position.
2. Make sure there is NOT an exter-
nal load on the weld terminals
nor the auxiliary power recepta-
cles.
1. With the Idler Switch (S4) in the
“Auto” position, check for the
presence of 12VDC at leads
#213 to #215 located at the
Idler Solenoid. If 12VDC is pre-
sent and the Idler Solenoid is
not activating, then the solenoid
may be faulty or there is a
mechanical restriction prevent-
ing it from functioning.
2. If there is NOT 12VDC at leads
#213 to #215, then test for
12VDC
from
lead
#213
to
ground (lead #5).
See
Diagram. If 12VDC is present,
then check lead #215 for conti-
nuity (zero ohms) from the Idler
Solenoid to the Printed Circuit
Board plug 3J1. If lead #215 is
OK, then the Printed Circuit
Board may be faulty. Replace.
3. If there is NOT 12VDC from
lead #213 to ground (lead #5),
then check the Idler Switch (S4)
for proper operation and as-
sociated wires for loose or faulty
connections.
