        Model:MZ 630D/1000/1250/1500Inverted submerged arc welding machine (dual characteristics)

        Functions:
        Submerged-arc welding, carbon arc gouging and manual metal-arc welding.

        Application industry:
        Shipbuilding, boiler, bridge, steel structure and wind tower.

        Features:
        It has the invert technology of soft switching, which is energy-saving and reliable;

        It has the constant-current characteristic, and the diameter of welding wire ranges from 3.0mm to 6.0mm;

        The wire feeder is driven by double rounds, and the elastic wire pressing guarantees the stable and reliable wire feed;

        Various trolleys are matched to meet the different needs for welding;

        It is light and small, so it is convenient for movement.

        It has the characteristics of the constant current and voltage, realizing the welding of thick wire, thin wire, power core,strip electrode and double-wire single-arc;

        It enables the parallel connection of several welding machines to realize the high-current output;

        It has the functions of overheating protection, turnoff protection and short-circuit protection;

        It has abundant peripheral interfaces, which are convenient to compose the special welding machine.
