Abstract
A power supply source is provided for use in apparatus for the welding of workpieces. It contains several parallel - connected charge-discharge circuits connected to electrodes via a choke or resistor, each of these circuits consists of storage capacitors, elements for the switching-over of the capacitor discharge and isolating diodes with common-polarity electrodes of said diodes being interconnected and connected to the electric network via a thyristor. Such arrangement allows generating current pulses of a complex shape, including nearly rectangular shape, and provides for controlling welding thermal cycles over a wide range. The arrangement is also of a small size and weight.
