description The present arrangement comprises a welding current generator for the generation of a d.c. portion of the desired welding current, as well as a pulse current source, the output circuits of which are connected in parallel with one another to the output terminals of the arrangement. The pulse current source is of the type having a high-frequency transformer in association with control means connected at the primary side thereof and delivers current pulses from a series of high-frequency pulses with a high no-load peak voltage. This enables pulsed welding currents to be generated in an extremely economical way by the employment of existing d.c. welding generators together with small, relatively low-cost additional equipment.
