Abstract

Title device has an additional working transformer, in the charging circuit of which there is a non-contacting selector switch, as well as one in its discharging circuit. There is a control unit for the non-contacting selector switch, and a limiting resistance in the charging circuit's feed line, together with an adjuster, the input of which is coupled to the addition working condenser, and the output to the control unit for the selector switches. The workpiece to be welded is interposed in the current circuit of the welding transformer's sec. coil via a limiting resistance. The output of the discharging circuit is coupled to the coil half of the welding transformer's prim. coil, and the output of an additional discharging circuit is coupled to its other coil half to ensure uninterrupted workpiece welding. This is effected by alternate discharge to the last of the alternately chargeable working condensers, with the charging of one causing the interruption of charging of the other.
