    MIG/MMA Welder
     Product Description :
    Product features
    1.Full bridge inversion soft-switching technology to effectively reduce IGBT working loss;
    2.DSP+CPLD microcomputer control technology to realize full digital control;
    3.Special and effective waveform control, reliable welding process with unapparent splashing;
    4.Two welding functions of DC manual welding and DC gas protective welding;
    5.Self-locking and non-self-locking control to reduce labor intensity;  and perfect performance.
    6.Wide working voltage range design, over 60% current output can still be ensured when three-phase input voltage is lowered to 250V;
    Application:
    Widely used in welding kind of material.
