•Disconnect input power by removing plug from receptacle before working inside SP170-I. Use only grounded receptacle. Do not touch electrically “hot” parts inside SP 170-I.

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

ROUTINE MAINTENANCE

POWER SOURCE COMPARTMENT

In extremely dusty locations, dirt may clog the air passages causing the welder to run hot. Blow dirt out of the welder with low pressure air at regular intervals to eliminate excessive dirt and dust build-up on interval 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.
