Press the "Process" button to select the MMA welding process:
The welding voltage is applied to the welding socket with a three second time
lag.
If the MMA welding process is selected, any cooling unit present is automat-
ically deactivated. It is not possible to switch it on.
NOTE!
Under certain circumstances, it may not be possible to change welding
parameters that have been set on a system component (such as remote con-
