SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

•Disconnect input power by removing plug from receptacle before working inside WELD-PAK 3200HD. Use only grounded receptacle. Do not touch elec- trically “hot” parts inside WELD-PAK 3200HD.

•Have qualified personnel do the mainte- nance and trouble shooting work.

ROUTINE MAINTENANCE

POWER SOURCE COMPARTMENT

No user serviceable parts inside! Do not attempt to perform service in the power source (fixed) side of the WELD-PAK 3200HD. 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 incoming guide tube and clean inside diameter if necessary.

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.
