    CHOPPER TECHNOLOGY FUNDAMENT ALS The new era of welding machines such as the Power MIG 350MP employ a technology whereby a DC source is turned on and off (chopped up) at high speed, then smoothed through an inductor to control an arc. Hence the name “Chopper .” The biggest advantage of chopper technology is the high-speed control of the arc, si ...
