The welding machine applies the most advanced inversion technology in the world.
The principle of inversion is to transform the power frequency of 50Hz/60Hz into direct current and invert it into high frequency through high-power device IGBT, then perform voltage-drop and commutation with the output high-power D.C power supply via Pulse Width Modulation (PWM). Since the switch power inversion technology is adopted, the weight and volume decrease greatly while the conversion efficiency increase by more than 30% o Its characteristics are: stable wire feed rate, little splatter, portable, energy-saving, low electromagnetic noise.
