The machines are heavy duty, fan cooled, three PCBS design, IGBT based inverter Digital controlled power sources for MMA weldding. The machine automatically provides operators with the optimal start and stop parameters based on the set welding current. A booster circut provides additional voltage for superior cellulosic arc starts and welding performance.
