Abstract

A compact, lightweight unit, for connection to single phase a.c. supply has accurate control of pulse width, p.r.f. and welding current amplitude for pulses of relatively complex shape esp. approx square. The energy storage is in a bank of capacitors each with discharge thyristor feeding the electrodes via a common choke resistor. Each capacitor is charged via a separate isolating diode whose like terminals are commoned to a thyristor connected in turn to the a.c. mains.
