-Main transformer uses super micri-crystal magnetic material.
-Using single tube IGBT,whose quality and price is better than mould IGBT.
-Air passage is of designed by protecting against water,dust and wind erosion,increases the stability of machine inner working.
-The fan heat diffusion efficiency can be up to 100%,greatly increases the duty cycle of welder.
-When working under 40 degree environment,the duty cycle is not less than 55%.
-The output efficiency can be up to 93%,the max power factor can be up to 0.95.
-Stable welding current in spite of input voltage fluctution.
-With arc force and hot arc starting function,also with VRD function.
