Electrode having a pure nickel core wire , designed for the welding of cast iron without or with low preheats (up to 300°C max). If possible, iron admixture should be kept low, thus using it preferably for filler and cover passes or for filling metal closely matches color or base metal. Easy arc striking, stable arc, finely-rippled bead surface . Weld metal is machinable. Weld short beads.
