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.
