Abstract
Plasma MIG welding in which a plasma flow is generated between a non-consumable electrode and a workpiece, and a consumable electrode is fed through such plasma flow toward the workpiece to establish a MIG arc between the same. The current intensity in the plasma flow is increased by applying additional current thereto from an annular auxiliary non-consumable electrode surrounding the plasma flow and positioned between the primary non-consumable electrode and the workpiece.
