Abstract

Process for igniting electric arc (16) between workpiece (17) and consumable electrode (11) comprises: supplying the electrode with energy; increasing the current to first adjustable value after contacting the electrode; constantly maintaining current until a pre-adjustable time period from contact of electrode with the workpiece has expired; and increasing current to further pre-adjustable value. Process for igniting an electric arc (16) between a workpiece (17) and a consumable electrode (11) according to the Lift Arc principle comprises: supplying the electrode with energy from a controlled current source; increasing the current from the constant current source (3) to a first adjustable value after contacting the electrode; constantly maintaining the current until a pre-adjustable time period from contact of the electrode with the workpiece has expired; and increasing the current to a further pre-adjustable value.
