CNC plasma cutting Plasma cutting performed by an industrial robot. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well.
A plasma torch (also known as a plasma arc, plasma gun, plasma cutter, or plasmatron) is a device for generating a directed flow of plasma. [1] [2] [3] The plasma jet can be used for applications including plasma cutting, plasma arc welding, plasma spraying, and plasma gasification for waste disposal. [4]

When used for cutting, the plasma gas flow is increased so that the deeply penetrating plasma jet cuts through the material and molten material is removed as cutting dross. PAC differs from oxy-fuel cutting in that the plasma process operates by using the arc to melt the metal whereas in the oxy-fuel process, the oxygen oxidizes the metal and ...
This Wikipedia article has already been disseminated throughout the internet claiming that a hand held plasma can usually cut 2" thick steel, and a automated table system can usually cut 6" thick steel. I believe the author confused plasma cutting with acetylene cutting.
This property is the key to the plasma window's usefulness – the technology of the plasma window allows radiation that can only be generated in a vacuum to be applied to objects in an atmosphere. [ 3 ] [ 4 ] Electron-beam welding is a major application of plasma windows, making it practical outside a hard vacuum.
Metalworking generally is divided into three categories: forming, cutting, and joining. Most metal cutting is done by high speed steel tools or carbide tools. [7] Each of these categories contains various processes. Prior to most operations, the metal must be marked out and/or measured, depending on the desired finished product.
Ady Hershcovitch is a plasma physicist best known for his 1995 invention, the plasma window, [1] which was later patented. (United States Patent: 5578831:Hershcovitch). [2] In the plasma window, a plasma (which is an ionized gas confined by electric and magnetic fields) separates air from a vacuum by preventing the air from rushing into the vacuum.
