Plasma Welding Machine

Plasma Arc Welding (PAW) is a modification of TIG(GTAW) Welding Process. As Plasma is an intense source of heat, it is used to fuse metals in this process and increase productivity. In PAW, as the electrode is placed within the body of the torch, plasma arc can be separated from the shielding gas. The plasma is then forced through a fine-bore copper nozzle, that compresses the arc and the plasma exits at very high velocity (approximately at the speed of sound) and a temperature approaching 28,000 °C (50,000 °F) or higher. Plasma is the temporary state of a gas.
