MIG/MAG functional sequences / operating modes

The following applies during the wire creep phase:
If there is no welding current flowing after 5 seconds (factory setting), the ignition process
is cancelled (ignition error).
The following applies during the welding phase:
If the arc is broken during the welding process and is not re-ignited within 5 seconds
(factory setting), there is an automatic cut-out.
There are optimum pre-sets for welding parameters such as gas pre-flow and free-burn, etc.
for numerous applications (although these can also be changed if required).
