INVERTER MMA WELDING MACHINE
UNMINI-200BX

The machines are fan cooled, Single PCB design, IGBT based inverter Digital controlled power sources for MMA welding. 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.
