ABSTRACT:
A welding system comprises a combined torch that includes a consumable electrode and a non-consumable electrode positioned so that their respective axes form an acute angle and so that arcs initiated from the electrodes intersect a workpiece plane to define an impingement point distance D, and a magnetic mechanism coupled to the torch and used for controlling the distance D during welding. The magnetic mechanism may be a magnetic shield inserted between the electrodes, or a separate magnetic device, e.g. a permanent magnet or electromagnet.
