1.anti-stick, 2.thermostsatic control 3.resistant to voltage fluctuation, 4.stable welding current 5.Hot start,arc f

Product characteristic: 1. High frequency, high erriciency, prominent saving effect. 2. It will protect by itself when it exceed the ratedvoltage, the rated current, the rated temperature, it is safe and endurale... 3. Automatic compensate by itself when the electrode net's voltage fluctuate, small arc, small spatter. 4. Well thrust adjust and automatic hot pilot arcfunctions, well pilot arc function. 5. Well welding quanlity, deep pond, high intensity. 6. Can long time continuan work, stable perfomance, high duty cycle. 7. Suitable for a variety of acid ,alkaline  and cellulose rod welding, welding support fibre welding rod welding, and can weld from down side.
