The NiFe-333N is a Nickel-Iron electrode for welding of cast iron. Especially suited for welding on larger dimensions in all positions, cast iron to steel, and for building up parts. High tensile strength.

The two types of UNITOR cast iron welding electrodes i.e., Nickel-333N (Pure Nickel) and NiFe-334N (Nickel Iron) whereby the pure nickel grade will produce a softer, more malleable weld deposit or lower strength and ductility than those of nickel iron.


  • Unitor high density polyethylene packing
  • Superb arc stability
  • Easy slag removal and smooth weld surface
  • High strength


  • Long storage lifespan without moisture pick up
  • Easy to use
  • Little surface treatment needed
  • Less possibility for joint failure during operation
