Product Description

Circuit principle:The large power component MOSFET(field-effect transistor) is adopted to convert 50/60Hz industrial frequency into high frequency (100KHZ above).Then, output large power DC source by declining the voltage, rectifying the current, and through pulse-width modulation (PWM) technology. The weight and volume of the main transformer is significantly declined and the efficiency is increased by 30% above.
Completer accessory:
1 set of 3m 70mm2 earth cable+500A earth clamp+KDP70A cable connector, 1 set of 3m 70mm2 welding cable+500A electrode holder+KDP70A cable connector. Option: remote controller with 15m cable.
