UNMMA-330YIT

INVERTER MMA WELDING MACHINE
UNMMA-330YIT

The machines are fan cooled, 2PCBS design,IGBT based inverter controlled power sources meant for MMA / TIG (scratch start)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.
