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, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops, automotive repair and restoration, industrial construction, and salvage and scrapping operations. You will need a compressor to supply air to your plasma cutter. At MTS Direct plasma cutters in stock for next day delivery from our warehouse and shop in Ballymount Ind. Est, Dublin Ireland.
