1) Cutting machine 
Plasma cutting is a process that is used to cut steel and other metals of different thicknesses (or sometimes other materials) using a plasma torch. In this process, an inert gas (in some units, compressed air) is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being...
cutting of a material by localized melting followed by the ejection of the molten part by the effect of a plasma flow produced by an arc plasma torch
A process used to cut stainless steel plate using a plasma torch. An inert gas is blown at high speed through a nozzle forming an electrical arc which forms a hot plasma for penetrating and cutting.
