Plasma cutting is a thermal cutting process that uses a high-velocity jet of ionized gas, known as plasma, to melt and cut through electrically conductive materials. The process begins by establishing an electric arc between a tungsten electrode and the workpiece. This arc ionizes the gas, creating a plasma stream that is then constricted and directed through a nozzle. The intense heat of the plasma, which can reach temperatures up to 20,000 degrees Celsius, melts the metal. The high-velocity gas jet then blows away the molten material, creating a clean cut.

Plasma cutting can be used on a wide variety of conductive metals, including steel, stainless steel, aluminum, copper, and brass. The thickness of the material that can be cut depends on the power of the plasma cutter and the type of gas used. Common gases include compressed air, nitrogen, oxygen, and argon. Air is the most common and cost-effective option for many applications.

The plasma cutting process offers several advantages. It can achieve high cutting speeds and produce a relatively narrow kerf, resulting in less material waste and a more precise cut. It can also cut materials with uneven or painted surfaces. However, it requires a power source, a gas supply, and a specialized torch. Safety precautions are important due to the intense heat, UV radiation, and fumes generated during the process. Plasma cutting is widely used in industries such as fabrication, manufacturing, construction, and repair.
