Plasma cutting is a process used to cut through electrically conductive materials, such as steel, aluminum, and copper. It works by creating a high-temperature plasma arc that melts the metal, allowing it to be blown away by a jet of compressed gas. This method is known for its speed and precision, making it popular in various industries, including manufacturing and construction. The equipment used in plasma cutting typically includes a power supply, a cutting torch, and a gas supply. The process can be automated or operated manually, depending on the application. Plasma cutting is effective for both thin and thick materials, providing clean cuts with minimal distortion.
