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
The machine will not idle down
to low RPM when weld and
auxiliary loads are removed.
The machine has normal weld
and auxiliary output. The engine
starts and shuts down normally.
(continued)
Check the solenoid for a
grounded coil; the resistance
between chassis ground and
either solenoid lead wire should
be 500k Ohms (500,000 Ohms)
minimum.
Apply battery voltage directly to
the solenoid leads and verify
that it is operating normally.
For code 10856, the solenoid
should pull in and hold firmly
when battery voltage is applied.
For codes 11199 and 11408,
apply battery voltage, for only an
instant, to the black and white
leads. The solenoid should pull
in immediately.
WARNING: Do not allow the
black and white
leads to remain
connected to battery.
Serious damage can
result.
Apply battery voltage to the
black and red leads. Manually
move the plunger into the
solenoid. The plunger should
hold tightly against the internal
stop and remain in that position
until the voltage is removed.
The 2-CR Reed relay may be
faulty. The reed relay should be
electrically open if no current is
flowing in the weld circuit. If
there is continuity through the
reed relay when the machine is
off, it is defective and should be
replaced.
