Applications

3.1.1

MMA welding

Manual arc welding or, for short, MMA welding. It is characterised by the fact that the arc burns between
a melting electrode and the molten pool. There is no external protection; any protection against the
atmosphere comes from the electrode.
3.1.2

TIG (Liftarc) welding

TIG welding process with arc ignition by means of workpiece contact.
