"1.Power ON self test (POST). when machine switched on , the system does full inspection and testing on welder conditions , that protect components especially key components like IGBT , diode , capacitors , circuit board , etc . 2. Full functions with thermal protection , over load protection , anti-stick , arc force , VRD . 3. Suitable for a wide range of voltage from 160V-260V . 50-60 Hz 4. energy saving . if the welder not in use for few minutes , the welder will automotically swtich to sleep mode . if still not use after sleep mode , the welder will swtich off automatically . 5.can be used to welder acid electrode rod and alkaline (basic ) electrode rod .
