Abstract

Summary form only given. The magnetic core of a transformer for welding devices has a moving magnetic shunt. The shunt can assume several different positions to modify the flux leakage values. These transformers are made to supply high current values: saturation of the magnetic core leads to strongly deformed voltage and current.
