Potential cause / remedy
A shutdown is imminent due to excess temperature.
Check process parameters.
Check coolant level and top up if necessary.
Check shielding gas supply.
Check min. flow rate.
Only a small amount of wire is left on the spool.
Wire feeder not connected; automatic circuit-breaker of wire
feed motor (reset the tripped automatic circuit-breaker by actua-
ting).
The inductance of the welding circuit is too high for the selected
welding task.
Check WF configuration.
One of several partial inverters is not supplying welding current.
Check temperature and switching thresholds.
[1]
The actual value of a welding parameter is outside the specified
tolerance field.
The resistance in the welding circuit is too high. Check earth
connection.
Switch the machine off and on. If the error persists, notify Ser-
vice.
The power limit of the mains fuse is reached and the welding
power is reduced. Check the fuse setting.
Check the gas supply.
Check the gas supply.
Check the gas supply.
