Coreless Welding Transformer

Abstract

The study of welding transformer with detailed sequence of operation is necessary. Parameters of welding type transformer compared to those of an ordinary step down transformer of equivalent ratings are distinct. Also these papers present a new method for manufacturing of arc welding type transformer. This method uses an auxiliary circuit and series coupled inductor and hence the number of tappings of simulation and experiment result are presented to show valuable operating of proposed method arcing starting.
