Discrete-time control of welding current in power sources of LC TYPE

A.E. Korotynsky

E.O. Paton Electric Welding Institute of the NASU 11 Kazymyr Malevych Str., 03150, Kyiv, Ukraine.

Abstract
Device with a discrete-time controller of welding current, based on thyristor-semistor commutator, is described. It is shown that its application in the secondary circuit makes the schematic diagram of the LC type power source much simplier. Results of technological tests of this device in welding using the rutile stick electrodes are given.
Keywords: arc welding, resonance welding machine, discrete-time control, resonance of voltages, series oscillatory circuit, transition process
