Plasma - 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. Common gases used for plasma cutting include oxygen, nitrogen, and air.
Oxy-Fuel Cutting - Oxy-fuel welding and oxy-fuel cutting are processes that use fuel gases and oxygen to weld or cut metals. Common fuel gases include acetylene, propylene, propane, and MAPP.
