Abstract

A pulsed d.c. welding supply includes an element 3 (e.g. a thyristor bridge) controlled so as to regulate the d.c. component, and an element 5 (a thyristor) to control the pulses according to the input voltage. The pulse control 300 is switched on a predetermined interval after energisation of the d.c. control 200.
