ROUTINE MAINTENANCE

POWER SOURCE COMPARTMENT

No user serviceable parts inside! Do not attempt to perform service in the power source (fixed) side of the SP-100T. Take the unit to an authorized Lincoln Service Center if you experi- ence 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

2.Occasionally inspect the incoming guide tube and clean inside diameter if necessary.

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