Abstract
The paper deals with a resistance welding machine powered from a high-frequency mains. Effect of working frequency increase compared to industrial frequency on the volume of machine transformer core was studied. It is shown that frequency increase does not lower the overall dimensions and weight of the transformer and it is not rational to supply power to AC resistance welding machines of medium and high power from a higher frequency inverter.
