7.3 Checklist for rectifying faults
The correct machine equipment for the material and process gas in use is a fundamental require-
ment for perfect operation!
Legend
Collective interference signal light illuminates
 Excess temperature, welding machine

Allow the machine to cool down whilst still switched on
 Welding current monitoring device triggered (stray welding currents flowing across the protective
earth). The error must be reset by switching the machine off and on again.

Welding wire is touching electrically conductive casing parts (check wire guide, has the welding
wire sprung off the wire spool?).

Check for a correct mounting of the welding lead. Fit the feeder clamp of the welding lead as
close as possible to the arc.
