Collective interference signal light illuminates
a
Excess temperature, welding machine
#
Allow the machine to cool down whilst still switched on
a
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.
Coolant error/no coolant flowing
a
Insufficient coolant flow
#
Check coolant level and refill if necessary
a
Air in the coolant circuit
#
see chapter "Vent coolant circuit"

a
Contact tip blocked
#
Clean, spray with anti-spatter spray and replace if necessary
a
