Abstract

In an arrangement for direct-current and/or alternating-current arc welding, comprising an inverter (11) for generating an alternating converter output current the frequency of which is higher than the mains frequency, the inverter (11) is connected via a rectifier (10) to a three-phase supply network RST and, furthermore, its output is connected via a transformer (13) to a workpiece (15) and to a welding electrode (16). In order to make welding possible with high powers and a wide control range, even at high inverter output current frequencies which are inaudible over the whole control range, the rectifier (10) is constructed as a three-phase bridge rectifier (17) containing thyristors (18) which is driven by a phase-shift control circuit (20), and several individual inverters (11a, 11b) are connected in parallel with one another with the output (36) of each converter being connected to a respective primary winding (13a, 13b) of the transformer (13). A transductor (37) is connected into the secondary circuit (38) of the transformer (13) for continuous adjustment via device (39) of the welding current/voltage. <IMAGE>
