Safety Precautions

WARNING

ELECTRIC SHOCK can kill.

Do not touch electrically live parts such as output terminals or internal wiring.

When inching with gun trigger, electrode and drive mechanism are “hot” to work and 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 drive roll and/or guide tubes.

Welding power source must be connected to system ground per the National Electrical Code or any applicable local codes.

Only qualified personnel should perform this installation.

Observe all additional Safety Guidelines detailed throughout this manual.

Routine Maintenance

Drive Rolls and Guide Tubes

After feeding every coil of wire, inspect the drive roll section. Clean it as necessary. Do not use a solvent for cleaning the idle roll because it may wash the lubricant out of the bearing. The driver roll and guide tubes are stamped with the wire sizes they will feed. If a wire size other than that stamped on the roll(s) is to be used, the roll(s) and guide tubes must be changed.

The drive rolls for .035” (0.9mm) through .052” (1.3mm) cored electrode and 1/16” (1.6mm) through 3/32” (2.4mm) electrode have a double set of teeth so they can be reversed for additional life. Drive rolls for

.023" (0.6 mm) through .052" (1.3 mm) solid elec- trodes and aluminum sizes have no teeth, but use two grooves so they also can be reversed for additional life.

See section on Wire Feed Drive Roll and Guide Tube Kits for roll changing instructions.

Wire Reel Mounting - 50 (22.7kg) and 60lb (27.2kg) Coils

To prolong the life of the reel shaft, periodically coat it with a thin layer of grease.

No maintenance of the two-position adjustable brake is needed. If the brake shoe wears through to the metal, replace the brake assembly.

Wire Reel Mounting - Readi-Reels and 10 through 30lb (4.5-14kg) Spools

No routine maintenance required. Do not lubricate 2” (51mm) spindle.

Avoiding Wire Feeding Problems

Wire feeding problems can be avoided by observing the following gun handling procedures:

a)Do not kink or pull cable around sharp corners.

b)Keep the electrode cable as straight as possible when welding or loading electrode through cable.

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.

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.

Gun and Cable Maintenance

See appropriate Operator’s Manual.
