Applications of Plasma Cutting With high speed and high efficiency, high kerf finish and wide cutting scope, plasma cutting has been widely applied in machinery, shipbuilding, steel-work, automobile, pressure vessel and various industries. And it is taking place the leading position of flame cutting in some fields. What is plasma cutting? This is a cutting system utilizing heat generated by arc discharge between the cutting object material and the electrode inside the torch. Arc discharge heat forms working gas into the plasma state of high temperature; the plasma jet of high temperature and high-speed is blown out from the nozzle; and the cutting object material is fused to be cut. Comparison of Plasma Cutting and Flame Cutting Plasma cutting is effective while working on metal conductor, such as low-carbon steel, aluminum and stainless steel. While cutting low-carbon steel, operator will experience faster and deeper cutting effect. Plasma cutting is ideal for cutting steel up to 1″ thick. Flame cutting, also known as oxy-fuel cutting, is a process that uses fuel gasses and oxygen to cut metals. The application scope is limited to ferrous metal that can be processed by oxidation technology. Flame cutting is ideal for cutting steel over ½” thick. Plasma cutting does not rely on oxidation treatment, and effectively cut aluminum, steel and other conductive metals. In addition, while cutting sheet metal, plasma cutting has faster cutting speed, higher efficiency and better effect than flame cutting.

The plasma cutting process uses electrically conductive gas to delivery energy from an electrical power supply through a plasma cutting torch to the cut material. The plasma gases include argon, hydrogen, nitrogen and mixtures, plus air and oxygen. Plasma Cutting Sample
