2.3. Brief Introduction
ARC series of welding machines adopt the latest Pulse Width Modulation (PWM)
technology and the Insulated Gate Bipolar Transistor (IGBT) power modules. It uses switching
frequencies in the 20KHz-50KHz ranges so as to replace the traditional line-frequency transformer
type welding machines. Thus, machines are characterized with portability, small size, lightweight,
low energy consumption and noise, etc.
ARC series of welding machines has excellent performance: constant current output makes
welding arc more stable; fast dynamic response speed reduces the impact from the arc length
fluctuation to the current; accurate stepless current adjustment and pre-setting function. There
are also some automatic protection functions for under voltage, over current, over heat, etc.
inside the welder, when the problems listed before occurred, the alarm light on the front panel is
