Plasma cutting consumables are replaceable parts of plasma torches that deteriorate as they are used. The shield protects the internal components of the torch from sparks and molten metal. The nozzle focuses the gas flow as well as the plasma arc. The electrode is commonly made from copper or silver with either tungsten or hafnium to conduct or transfer current from the torch to the plate. Swirl rings direct the gas flow for optimum content mixture while retaining caps holds the stack together. AIMS Industrial offers a great selection of plasma cutting consumables for various fabrication, construction, automotive repair, and other industrial applications.
