Abstract
Abstract A novel pulse generator for pulse arc welding and building up of parts by one or several arcs is disclosed, the novel generator comprising a pulse unit and a control unit. The pulse unit comprises a transformer, the number of secondary windings of which corresponds to the number of welding arcs, or the number of secondary windings is half the number of welding arcs, so as to ensure simultaneous operation of the required number of welding arcs.
