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.
