1.Auto compensation against power fluctation,satable,welding current 2.protection against power flutuation ,stable welding curr

Uses high power MOSFET  to convert industrial frequency(50/60hz)into high frequency(>100khz),which is then reduced and rectified .the product can then output high power DCsource with the use of PWMtechnology,the main reansformer can  thus reduce dramatically in size and weight,with the efficiency enhanced by more than 30%.
