Abstract
Plasma-MIG welding in which a thermally ionizable inert gas is flowed past a starter non-consumable electrode through a nozzle non-consumable electrode toward a workpiece, firstly a plasma arc is established between such starter non-consumable electrode and such workpiece to initiate and sustain a plasma flow, a consumable electrode is fed through such plasma flow toward the workpiece, secondly a MIG-arc is separately established between such consumable electrode and the workpiece, and finally the nozzle non-consumable electrode is electrically connected to the starter non-consumable electrode so that the plasma arc is taken over by the nozzle non-consumable electrode and extends solely from the nozzle non-consumable electrode to the workpiece.
