Abstract

A method for reducing the generation of noise during arc welding by alternating current with welding machines with clocked current sources is disclosed. By modifying the curent set value on the control side with temporally non-linear functions by a digital-analog converter, a flow of the welding current which has limited upper tones can be generated.
