Abstract

In an arrangement for direct- current and/or alternating-current welding, comprising a converter (11) for generating an alternating converter output current with a frequency which is higher than the mains frequency, the converter (11) is provided with controllable switching elements (22, 23) and at least one commutating capacitor (20, 21) and its output is connected via a transformer (13) to a workpiece (15) and a welding electrode (16). In order to prevent the switching elements (22, 23) from being destroyed at frequencies of more than 20 Kilohertz and during welding operations, the primary winding (13a) of the transformer (13) is divided in accordance with the number of switching elements (22, 23) and one primary winding section (31 and 32) each is connected to one switching element (22 and 23) and one commutating capacitor (20 and 21). Full bridge converter arrangements are described with reference to Figs. 2 and 3 (not shown). <IMAGE>
