Abstract

PROBLEM TO BE SOLVED: To obtain a power supply in which a high current is obtained instantaneously by performing the inverter control of a step-down transformer with energy stored in a battery. SOLUTION: The high current power supply comprises an electric circuit section for charging a battery, a step-down transformer and an inverter drive section, an inverter controller section, and a welding head section. A current as high as 10,000A-25,000A is obtained from a commercial power supply for home or a small generator without requiring a large scale power receiving facility.
