For surfacing iron-nickel alloy. Used for welding ductile iron, malleable iron, cast iron with nodular graphite, and gray iron.

Suitable for welding high fluoride castings.

They are used for welding machine frames, pump casings, cylinder blocks, gearbox housings, etc.

The material is highly resistant to cracking and can be easily machined with cutting tools.

Cooking post. (DC) current (negative polarity) or alternating current. (AC).

At constant, greater penetration is achieved (an advantage in fillet welding).

Positional welding is better to carry out the change. current (AC). Before welding, clean the surface in the welding area.

Hold the electrode vertically, the arc is short.

When welding brittle grades of cast iron, it is imperative to straighten it to relieve internal stresses.

MNP-2 electrodes are close analogues.
