Jasic MIG 250T Single Phase Welding Machine. MIG IGBT Welding Machine Using IGBT technology The cycle is very high, so it can weld for a long time MIG welding uses a control circuit, stable welding arc, a little spark, a beautiful and efficient shape Using a 20KHz frequency inverter, can reduce the volume and weight of the machine Can transfer frequencies on the outer audio range, which almost eliminates noise pollution
