More Information
Summary:A control device having a single static converter incorporating a rectifier and stabilizer block and a transistorized inversion block, the output signal of which is controlled by an amplitude and frequency regulator in response to a feedback signal taken off the primary or the secondary winding of the welding transformer. The device features an additional rectifier block located between the output from the secondary winding and the input to the welding rollers.
