1. Adopt the soft switch technology, high efficiency, low power consumption
2. Automatic protection from ovecurrent, overheat, over/under voltage
3. Support AC/DC square-wave TIG welding, DC TIG welding, MMA welding
4. Small size, light weight, high shift efficiency, energy saving, strong adaptability of the voltage
5. In TIG welding, the up/down slope of welding current adjustable, and support pre-gas sending and delay gas sending
6. HF automatically strike arc, and extinguishes automatically after the arc is successfully started
7. In MMA welding, can be used together with almost all kinds of welding electrode with a diameter below 5.0mm
8. While DC TIG welding is adopted, can weld stainless steel, alloy steel, copper, silver, titanium
9. While AC square-wave welding is adopted, can weld stainless steel, alloy steel, copper, silver, titanium
10. Adopt inverter technology twice, pure square-wave output, heat concentrated, strong reverse clearance capability; Cleaning frequency and ratio can be adjusted, can easily adjust the result of deoxidation in aluminum welding. The mixing ratio and frequency is preset, can effectively protect the tungsten electrode and prolong its service life.
11. Can be equipped with the distance control box to realize the distance control, simplify the operation.
12. A voltage fluctuation of ± 20% is allowable
