AVOIDING WIRE FEEDING PROBLEMS
Wire feeding problems can be avoided by observing
the following gun handling and feeder set up proce-
dures:
a) Do not bend the conduit more than 45°.
b) Keep the minimum amount of conduit necessary
for the wire reel to connect to the wire feeder.
c) Do not allow dolly wheels or trucks to run over
cables.
d) Keep cable clean by following maintenance
instructions.
e) Use only clean, rust-free electrode. The Lincoln
electrodes have proper surface lubrication.
f) Replace contact tip when the arc starts to become
unstable or the contact tip end is fused or
deformed.
g) Do not use excessive wire spindle brake settings.
h) Use proper drive rolls, wire guides and drive roll
pressure settings.
PERIODIC MAINTENANCE
Wire Drive Motor and Gearbox
Every year inspect the gearbox and coat the gear
teeth with a moly-disulfide filled grease. Do not use
graphite grease.
Every six months check the motor brushes. Replace
them if they are less than 1/4” long.
SAFETY PRECAUTIONS
ROUTINE MAINTENANCE
Drive Rolls and Guide Tubes
After feeding every coil of wire, inspect the feed plate
and drive rolls. Clean them as necessary.
All drive rolls have two identical grooves. The rolls
may be flipped over to use the other groove.
See “Procedure to Install Drive Rolls and Wire
Guides” in the INSTALLATION section for roll chang-
ing instructions.

ground and could remain energized several
seconds after the gun trigger is released.
• Turn OFF input power at welding power
source before installation or changing
