TIG-315PW AC DC TIG Welder IGBT Inverter AC DC TIG Welding Machine

In Stock

1. Multi-function digital control welding machine, features DC TIG, pulsed DC TIG, pulsed AC TIG, and MMA welding in one unit; simple design, small size, lightweight, and multilayer control circuit board, ensures high reliability and longer service life.
2. Thanks to the secondary inverting technology, it features pure square wave output, excellent arc force performance, and wide cleaning range to ensure high-quality welding results.
3. It features excellent weld characteristics; easy arc starting; reliable and stable arc performance.
4. Thanks to the high frequency & high voltage arc ignition circuit, it realizes excellent arc starting with a 99.9% success rate, especially suits for different types of spot welding.
5. Pulsed welding with adjustable pulse frequency, achieving high-quality welding of thin metal sheets, dissimilar metal, materials of different thicknesses, and even the requirements of double-sided forming welds.
6. Available to adjust current freely with a foot switch; When it starts to spit wires during welding, use it to increase current value and make rapid heating; Once welding ends, use it to decrease current to generate a weld seam. With a foot switch, it is able to improve welding efficiency and reduce welding difficulties to ensure welding quality.
7. Overheat protection improves the high reliability of the machine.
