Plasma arc welding is an advanced version of tungsten inert gas (TIG) welding. While TIG welding features an open arc shielded by argon or helium, plasma arc welding uses a specialized torch. This torch has a nozzle that constricts the arc, and the shielding gas is supplied separately by the torch.
A Plasma Arc Welding Machine is a device used for plasma arc welding, an advanced welding technique. This machine utilizes a specialized torch to create a constricted arc between the electrode and the workpiece. The torch also supplies shielding gas separately to protect the weld area. This setup allows for precise, high-quality welds, especially useful for intricate or critical welding tasks.

Plasma arc welding (PAW) is an advanced version of the tungsten inert gas (TIG) welding process.
The arc is formed between the electrode (usually made of tungsten) and the workpiece.
The main difference with GTAW is that in PAW the plasma arc can be separated from the shielding gas blanket by positioning the electrode inside the welding torch body.
Virtually all welding arcs are (partially ionized) plasmas, but the plasma in plasma arc welding is a constricted arc.
The constriction not only increases the temperature of the arc, but also gives it a thin beam shape.
This enables welding with high speeds, greater penetration, a narrow HAZ (heat affected zone) and minimal heat input.
