MF inverter spot welder has the following features compared with ordinary AC resistance spot welder:

1. high welding stability;
2. power saving more than 30%, low operating costs;
3. three-phase power supply balanced input, power factor up to 95%;
4. lower welding current and electrode pressure;
5. secondary circuit almost no induction energy loss;
6. electrode life is more than doubled, reducing electrode repair and grinding time;
7. substantial savings in power installation and water, gas and other auxiliary facilities installation costs;
8. more accurate, faster, more comprehensive control and analysis of welding parameters;
9. shorter welding time, improve work efficiency and welding quality;
10. a wider range of welding, on mild steel, stainless steel, copper, aluminum, galvanized plate welding effect is better.
