Plasma Cutting

Plasma cutting involves ionised gas at temperatures above 20,000°C used to melt and expel material. Plasma is a state of matter which is where a solid is heated, and it changes into a liquid. If this is heated again, it will become a gas, and this gas will become ionised and electrically conductive becoming 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. The plasma arc can cut a variety of electrically conductive alloys such as plain carbon, stainless steels, aluminium as well as its alloys, nickel alloys and titanium. The plasma cutting method was initially developed to cut materials that could not be satisfactorily cut by the oxy-fuel process. Plasma cutting can also be achieved underwater using specialised equipment. The material stays stationary and the plasma torch cuts it out by moving around it. Plasma cutting is often used in fabrication shops, automotive repair and restoration, industrial construction, and salvage and scrapping operations.
