ROUTINE MAINTENANCE

 

 

POWER SOURCE COMPARTMENT

 

 

No user serviceable parts inside! Do not attempt to perform

 

 

service in the power source (fixed) side of the POWER MIG

 

 

(140, 180 MODELS). Take the unit to an authorized Lincoln

 

 

Service Center if you experience problems. NO maintenance

 

 

is required.

 

 

In extremely dusty locations, dirt may clog the air passages

 

 

causing the welder to run hot with premature tripping of ther-

 

 

mal protection. If so, blow dirt out of the welder with low pres-

 

 

sure air at regular intervals to eliminate excessive dirt and dust

 

 

build-up on internal parts.

 

WIRE FEED COMPARTMENT

1. When necessary, vacuum accumulated dirt from gearbox and wire feed section.

2. Occasionally inspect the wire guides and keep grooves clean.

3. Motor and gearbox have lifetime lubrication and require no maintenance.

FAN MOTOR

Has lifetime lubrication — requires no maintenance.

WIRE REEL SPINDLE

Requires no maintenance. Do not lubricate shaft.
