Product Description
This welding machine in the AC/DC TIG series, inverts the 50/60Hz power supply to
a high-frequency, high-voltage power supply of up to 20KHz. The inversion process
is facilitated by a powerful IGBT device followed by step-down rectification and
pulse-width modulation (PWM) technology producing a high-power DC output
