The invention relates to welding equipment and can be widely used in various branches of machine building. A power supply for arc welding with alternating current of high frequency contains a welding transformer, two bridge controlled rectifiers with a control units. The welding transformer has two primary windings, in the case the first of the windings is connected to the output of the single-phase bridge controlled rectifier, which input is connected to two phases of three-phase network. The second winding is connected to the output of the second single-phase bridge controlled rectifier, which input is connected to the third phase of the mains supply and to the neutral wire. The first and second windings have corresponding coil ratio, controlled valves of both controlled rectifier bridges - corresponding angle of unblocking. The embodiment of power supply provides for increasing operation reliability and efficiency factor thereof on account of simplifying the power supply scheme.
