COURSE OF ACTION
FUNCTION PROBLEMS
The CV output contactor does not
pull in when using a wire feeder
with a control cable connected to
the RANGER 10-LX amphenol.
1. Make sure the Wire Feeder
switch (S8) is in the “WITH
CONTROL CABLE” position.
2. Install a jumper wire from pins
“D” to “C” on the 14 pin amphe-
nol. If the output contactor acti-
vates, the problem is external to
the RANGER 10-LX. The wire
feeder or control cable may be
faulty.
1. With the jumper installed in pins
“D” and “C” in the 14 pin
amphenol, check for 12VDC
from leads #224F(+) to #2C(-) at
the CV output contactor. If
12VDC is present and the con-
tactor does NOT activate, then
the contactor may be defective.
2. If the correct voltage is NOT
present in Step #1, check from
lead #224F to ground (lead #5)
for the presence of 12VDC. If
12VDC is present, then check
the continuity of lead 2C
through the RF bypass board to
the 14 pin amphenol. See
Wiring Diagram.
3. If 12VDC is NOT present from
lead #224F to ground (lead #5),
then check the #224F lead for
an open circuit. See Wiring
Diagram.

tact the Lincoln Electric Service Department for electrical troubleshooting assistance before you proceed. Call
