Plasma Arc Cutting Torch

This process is based on an electrical arc between an electrode inside a torch and the workpiece.

Plasma arc cutting torch.

The plasma jet can be used for applications including plasma cutting plasma arc welding plasma spraying and plasma gasification for waste disposal. Typical materials cut with a plasma torch include steel stainless steel aluminum brass and copper although other conductive metals may be cut as well. The plasma arc formation begins when a gas such as oxygen nitrogen argon or even shop air is forced through a small nozzle orifice inside the torch. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma.

A plasma torch also known as a plasma arc plasma gun or plasma cutter plasmatron is a device for generating a directed flow of plasma. A plasma cutter will use this electrically conductive gas to transfer energy from a power supply to any conductive material resulting in a cleaner faster cutting process than with oxyfuel. Another very common thermal cutting technique is plasma arc cutting. A gas such as argon nitrogen hydrogen or air is injected into the arc inside the torch turning it into a plasma with a temperature of more than 10 000 c.
