ABSTRACT:
A control station for use with multiple operator power supplies in a semiautomatic welding system is disclosed. The system utilizes a constant-potential multiple operator unit, suitable for gas-metal arc spray transfer welding, to which control stations may be connected to provide satisfactory short-circuiting arc operation for selected operators. The control station comprises a plurality of resistors selectably connectable in specified parallel relationships through switching means and an iron core inductor to provide the required operating characteristics for short-circuit welding.
