Abstract

Connection device for adjusting, regulating and rectifying the voltage and/or current of a three-phase welding transformer, characterized by the fact that on the secondary side of the welding transformer (10) three thyristors (SCR1, SCR2, SCR3) that are coupled on the input side with the secondary windings (W', W'', W''') connected to each other to form one of the poles (P1) of the welding circuit and whose outputs are connected each other to form the other pole (P2) of the welding circuit.
