CAUTION
PROBLEMS
(SYMPTOMS)
POSSIBLE
CAUSE
RECOMMENDED
COURSE OF ACTION
Inconsistent wire feeding or wire not
feeding but drive rolls turning. 1. The gun cable is kinked and/or
twisted. Keep the gun cable as
straight as possible. Avoid sharp
corners or bends in the cable.
2. The wire is jammed in the gun
and cable. Remove the gun from
the wire feeder and pull the
jammed wire out of the gun and
cable.
3. The gun liner is dirty or worn.
Blow dirt out of the liner with low
pressure (40psi or less). Replace
the liner if worn.
4. The electrode is rusty or dirty.
Use only clean electrode. Use
quality electrode, like L-50 or
Super Arc L-56 from Lincoln
Electric.
5. The contact tip is partially melted
or has spatter. Replace the con-
tact tip.
6. Improper gun liner, tip, drive rolls
and/or inner wire guide. Verify the
proper parts are installed.
7. Incorrect tension arm pressure on
the drive rolls. Adjust the tension
arm per the Instruction Manual.
Most electrodes feed well at a
tension arm setting of "3".
8. Worn drive roll. Replace the drive
rolls if worn or filled with dirt.
If all recommended possible areas of
misadjustment have been checked
and the problem persists, Contact
your local Lincoln Authorized
Field Service Facility.
