Abstract
1,207,696. Welding supply systems. SIEMENS A.G. 31 July, 1968 [8 Aug., 1967], No. 36610/68. Heading H2H. A welding machine comprises a transformer having its polyphase primary windings 2 each in series with opposed parallel controllable rectifiers 6 and its secondary winding 3 connected to the welding load 5 to provide welding current with reduced frequency. An additional transformer winding 4 is supplied from a unidirectional voltage source 8 and controlled in relationship with the firing of the rectifiers 6 to premagnetize the transformer core in the direction opposite to the direction of the subsequent magnetization. The core may be premagnetized to saturation.
