Plasma cutters are used to cut electrically conductive materials like steel, metal sheet, brass, and copper. Increasingly popular tools, plasma cutters send an electric arc through a compressed gas (e.g., argon, nitrogen, or oxygen) that passes through a focused nozzle at high speed. The electric arc ionizes the compressed gas, elevating its temperature and converting it into the fourth state of matter, plasma. While plasma cutters may easily cut through metal, they can’t cut through non-electrically conductive materials like wood and plastic. Check out our 36 listings of Plasma Cutters today!
