Warning
Potential cause / remedy
2
Half-wave failures
Check process parameters.
3
Torch cooling warning
Check coolant level and top up if necessary.
4
Shielding gas
Check shielding gas supply.
5
Coolant flow
Check min. flow rate.

6
Wire reserve
Only a small amount of wire is left on the spool.
7
CAN bus failure
Wire feeder not connected; automatic circuit-breaker of wire
feed motor (reset the tripped automatic circuit-breaker by actu-
ating).
8
Welding circuit
The inductance of the welding circuit is too high for the selected
welding task.
9
WF configuration
Check WF configuration.
10
Partial inverter
One of several partial inverters is not supplying welding current.
11
Excess temperature of the coo-
lant
[1]
Check temperature and switching thresholds.

12
Welding monitoring
The actual value of a welding parameter is outside the specified
tolerance field.
13
Contact error
