1. Three-phase power supply, grid balance, small impact on the grid
The power factor is as high as 0.7-0.9 (power frequency 0.4), which greatly reduces the reactive power loss;

2. Significantly improved welding control accuracy
The inverter frequency reaches above 1000Hz, and the welding current control ability and control accuracy are 20 times higher than those of AC welding machines;

3. Great leap in welding quality
The current waveform is straight, the size of the nugget is stable, the spatter is less, and the surface quality of the solder
joint is good;

4. Save basic investment and save energy
The grid power demand is low, only 2/3 of the AC resistance welding machine; the welding time is short and the electrode life is long;

5. Human-computer interface, easy to operate
Multiple sets of welding specifications can be stored and called with one key, real-time display of welding current and time; monitoring and alarm functions of welding pressure, cold water flow, and welding current.
