Specification :

oerlikon CITOFONTE Mo welding electrodes AWS SFA 5.15: E NiCu-B Electrode having a nickel-copper core wire for welding cast iron without or with low preheating (up to +300oC). Iron admixture from base metal should be kept low. Thus, electrode is preferably used for making filler and cover passes or for filling-up shrinkage cavities. It is advisable to "butter" groove faces with OERLIKON CITOFONTE Ni. Weld metal closely matches colour of base metal. Easy arc striking and restriking, stable arc, smooth bead surface. Weld metal is machinable. Weld short beads. Well-suited to welding cast iron with lamellar graphite, white and black heart malleable cast iron,
nodular cast iron.
