Nihonweld NC-100 description: Shielded Metal Arc Welding electrode used primarily for the reclamation and repair of casting defects, machining errors, shrinkage cavities, gas blow holes and voids resulting from defect excavation of grey iron castings. The electrode is manufactured using a pure nickel core wire and gives a fully machinable weld deposit. NC-100 has been specifically designed to produce a very fluid molten pool with good wetting properties making it particularly suitable for the filing of casting defects. An all positional electrode suitable for use with both AC (minimum OCV of 50V) and DC+. Deposit is free from hard zones, cracks and porosity. Low current requirements. Tensile strength and ductility adequate for cast iron.
