Abstract

An arrangement for controlling current in direct current arc welding comprising a sensing resistance to the current arranged in series with the arc, means for comparing the signal of said resistance with a desired signal and passing the signal difference to amplifying means with the in order to provide negative feedback to a current control stage to transistors in the arc circuit.
