As electricity from the cutter torch travels down this plasma it delivers sufficient heat to melt through the workpiece. The electrical arc ionizes some of the gas, thereby creating an electrically conductive channel of plasma. An electrical arc is then formed within the gas, between an electrode near or integrated into the gas nozzle and the workpiece itself. This is accomplished by a compressed gas (oxygen, air, inert and others depending on material being cut) which is blown through a focused nozzle at high speed toward the workpiece. plasma from the plasma cutter itself, through the workpiece to be cut, thus forming a completed electric circuit back to the plasma cutter through a grounding clamp. The basic plasma cutting process involves creating an electrical channel of superheated, electrically ionized gas i.e.

Due to the high speed and precision cuts combined with low cost, plasma cutting sees widespread use from large-scale industrial computer numerical control (CNC) applications down to small hobbyist shops. Plasma cutting is often used in fabrication shops, automotive repair and restoration, industrial construction, and salvage and scrapping operations. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma.
