Nihonweld NFG description: Special purpose manual metal arc electrode for the arc cutting, grooving and piercing of ferrous and non-ferrous metals and back gouging weld preparations for a wide range of repair and maintenance applications. Metal –arc cutting with NFG occurs as a result of melting and removal of metal along desired line of travel using an electric arc struck between the work piece and a special desired line of travel using an electric arc struck between the work piece and a special covered electrode. The electrode coating is specifically designed to:
Concentrate a forceful and penetrating arc
Stabilize the arc and prevent its extinction
Blow the molten metal and dross away with a positive jet of gasses.
