Product Description
Features

1. Adopt the soft switch technology, high efficiency, low power consumption

2. Automatic protection from overcurrent, overheat, over/under voltage

3. Support DC TIG welding, pulse TIG welding and MMA welding, can weld such metals as stainless steel, alloy steel, copper, silver, titanium, etc.

4. In TIG welding, can select DC or pulse welding according to the requirements, can adjust the peak/bottom current, pulse duty circle and frequency according to the size of welding seam

5. In TIG welding, HF automatically strikes arc, and extinguish automatically after the arc is successfully stroke, high efficiency

6. With the long/short seam switch and gas/water cooling switch, can make selection according to the actual need

7. In MMA welding, csuitable for the electrode with a diameter of below 5.8mm

8. Can realize TIG grounding and MMA covering once a time, high efficiency, especially suitable for the welding of thin rare-metal board

9. A voltage fluctuation of ± 20% is allowable.
