ROUTINE MAINTENANCE

POWER SOURCE COMPARTMENT

No user serviceable parts inside! Do not attempt to perform service in the power source (fixed) side of the COMPACT EIRE WELDERS. Take the unit to an authorized Lincoln Service Center if you experience problems.

TYPCALLY, No regular maintenance is required. In extremely dusty locations, dirt may clog the air passages causing the welder to run hot with premature tripping of thermal protection. If so, blow dirt out of the welder with low pressure air at regular intervals to eliminate excessive dirt and dust build-up on inter- nal 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
