1. Power Source: Adopt medium frequency inverter welding source. Duty cycle rate reaches 50%. The three-phase power supply is under rectifying through a special inverter and converted to 1000Hz AC voltage and then be transmitted to a medium frequency transformer to be rectified so as to provide DC welding current. Compare with general AC pulse power supply, this kind of power source could be fast and precisely adjusted. Small impact to the power grid and lower requirement for the power grid compare with the single-phase welder of the same capacity.

2. Row Welding Structure: 6 sets of welding electrodes are installed on the beam and equipped with slide guide that could move horizontally. It is convenient to adjust the distance of welding spot so it is suitable for welding the work pieces with different pinch. The welding program of row welding electrode is flexible and various kinds of welding programs are available. So you could choose to weld from the middle to the sides or from the sides to the middle or single welding. Truly achieve the stable, reliable and good consistency of welding effect.
