The proposed welding transformer contains two toroidal magnetic cores with a primary winding and a secondary winding, which are connected in series. The secondary winding enclosures the primary winding. Each winding has three terminals - the terminal of the start of the winding of the first magnetic core, the terminal of the end of the winding of the second magnetic core, and the terminal of the point of the connection of the windings of the first and the second magnetic cores. The terminals of the primary windings are connected to the terminals for connecting the transformers to the mains, and the terminals of the secondary windings are connected to the terminals for connecting the rectifier and the current controller of the transformer.
