Abstract

The utility model relates to the electrical engineering and is provided for welding. The controllable three-phse power source for welding contains a three-phase transformer with a three-leg core magnetic circuit, on each core of which there are placed the primary and secondary windings, connected to the rectifier unit, and a magnetic regulator shunt. Each core of the magnetic circuit is made as a pack of plane semi-rings. The cores are fixed at an angle of 120° on an axis, in the middle part of which inside the transformer it is rigidly fixed a magnetic shunt in the form of a three-ray star, the axis being supported in bearings and the windings are made of two parts, basic and auxiliary. The technical result consists in reducing the asymmetry of the magnetic circuit. Claims: 1 Fig.: 3
