Estimating the term…
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.
Apparatus comprising electrodes for the welding of workpieces, a power supply network, a plurality of charge-discharge circuits connected in parallel;
A power supply source for the welding of a workpiece and operable from an A.C. supply and comprising electrodes one of which is a workpiece to be welded, said electrodes being spaced from each other to form a spark gap;
A power supply source for welding and operable from an A.C. supply and comprising electrodes, one of which is a workpiece to be welded, said electrodes being spaced from each other to form a spark gap;
A welding power source operable from a pair of A-C terminals and comprising electrodes, one of which is a workpiece to be welded, said electrodes being spaced to form an arc gap;
