I. Advanced design, high efficiency, small volume, light weight, stable and reliable operation.

II. Non-load consume is less than 40W, energy saving and high efficient.

III. Automatic compensation for electricity voltage pulsation, stable welding current, easy arc initiation, fast dynamic response, no welding noise, low welding spatter, smooth welding apprarance.

IV. Suitable for various acid and alkali welding rods, also stainless steel welding rods.

V. Good overvoltage protection, if 110V connects to 220V by mistake, 220V connects to 380V by mistake, won't be damaged.

VI. When over-voltage and short circuit occur , the machine can be protected automatically.
