1. Transformer with movable secondary winding, especially for welding, including a stationary primary winding, a magnetic circuit with columns (1) and yokes, a secondary winding (2) movable in relation to the primary winding by means of a screw coupling (12), a coil winding (3) and rectifiers (10) with coolers (9), characterised by the fact that the secondary winding (2) coils are bonded to supports (4) with a trough-shaped cross-section and interconnected by the rectifier coolers (9), and that the screw coupling (12) is designed with its first projections (16) in the centre part of each support (4), extending towards the centre line of the screw coupling (12) and in connection with it.
