What are the characteristics and uses of AC and DC TIG welding machines?
1. The minimum welding current is from 5A, the arc stability is good, and it can weld a variety of thin, medium and thick plates;
2. DC pulse argon arc welding is suitable for welding stainless steel, copper, titanium, carbon steel and other materials;
3. External characteristics can be obtained during AC, and the welding current waveform is a square wave that quickly crosses zero, which is beneficial to the welding current and arc stability;
4. AC argon arc welding is suitable for welding aluminum, aluminum alloy and other materials;
5. It can be adjusted by adjusting the pulse base time and the atomization zone, and the gas lag off time is steplessly adjusted, especially to meet higher welding process requirements;
6.Using AC / DC argon arc welding, AC / DC pulse argon arc welding, AC / DC manual ordinary welding, AC / DC spot welding;
7. With the function of slow rise and decay of welding current, it is beneficial to fill the crater when the arc is closed and avoid cracks in the weld.
