1.IGBT MMA three phase welding machine, 2.With stable current and good function of auto-compensation against power fluctuation - details see: https://www.machineto.com/mma-400a-inverter-mma-welders-igbt-uni-transistor-series-10134463

Inverter MMA welders (IGBT Uni-Transistor Series)

[Features and applications]

Raise the frequency from 50/60hz to high frequency .E.g.50khz.After reducing the voltage and rectifying,output powerful Dc with the technology of PWM.The weight and size of the main transformer decrease dramatically but the efficieny will rise by over 30%.

1.With the function of auto-compensation against power fluctuation.And the output welding current will be stable;

2.Having the function of auto-protecting against over-voltage and over current;

3.Having powerful arc-force;

4.Reliable quality with small dimension and weight as well as high efficiency;

5.Able to weld basic and acid electrodes;Applicable to low carbon steel,mediem carton steel and alloy steel.
