Automatic cut-out
Once the fault periods have elapsed, the automatic cut-out stops the welding process when it has been
triggered by one of two states:
• During ignition
5 s after the start of the welding process, no welding current flows (ignition error).
• During welding
The arc is interrupted for more than 5 s (arc interruption).
