Peculiarities of operation of the resonant-type welding equipment based on a modular principle are considered. It is shown that this approach allows energy consumption to be decreased and also reliability of operation of the equipment to be substantially improved. Simplified calculation of the transition process in module on-off is given and it is shown on its base that the disturbances by current in welding circuit are eliminated as a result of a dynamic mutual compensation
Keywords: arc welding, resonant welding unit, energy saving, module, dynamic compensation
