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 maintenance work.

Observe all additional Safety Guidelines detailed throughout this manual.

ROUTINE MAINTENANCE

Gun and Cable connection: After feeding every coil of wire; check tightness of gun connection to wire feed brass bushing.

Drive Rolls and Guide Tubes

After feeding every coil of wire, inspect the drive roll section. Clean it as necessary. The driver rolls and Inner Wire Guides 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 Inner Wire Guides must be changed.

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.

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

No routine maintenance required.

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 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.

h)Use proper drive rolls, wire guides and drive roll pressure settings.

PERIODIC MAINTENANCE

•Every year inspect the gearbox and coat the teeth with a Moly-disulfide grease. Do Not use graphite grease.

•Every six months check the motor brushes. Replace them if they are less than 1/4" long.

•Replace the drive rolls and inner wire guide when they are worn.

•Replace the pig tail if the insulation is cut, abraded or damaged.

Gun and Cable Maintenance

See appropriate Operator’s Manual.

Procedure for Removing Feedplate from Wire Feeder

1)Loosen the clamping collar screw using a 3/16" Allen wrench. The clamping collar screw is accessed from the bottom of the feedplate. It is the screw which is perpendicular to the feeding direction.

2)Loosen the retaining screw, which is also accessed from bottom of feeder, using a 3/16" Allen wrench. Continue to loosen the screw until the feedplate can be easily pulled off of the wire feeder.
