General Maintenance
1. The fan motor has sealed ball bearings which
requires no service.
2. In dusty locations dirt may clog the air channels
causing the welder to run hot. Under these
conditions carefully blow out the welder at regular
intervals.
3. Keep the electrode and work cable connection
tight.
4.
Every twelve months or at the first indication of a
binding current pointer, turn the input power off
and remove the left case side. Wipe the pointer

grease.

reactor quadrant teeth, drive gear and pinion.
