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
