Premium Nickel Arc Welding Electrodes
WELDarc Castweld 99 Nickel Iron (98% Ni) is a graphite nickel type electrode, used in repair and maintenance welding of cast irons. Its nickel filler material deposited metal shows excellent mechanical properties and crack resistance, a good colour match to most cast irons. This electrode is an excellent high nickel alloy material for the build up and the joining of cast iron. Preheating and post heating may apply in some applications.

Keep Dry - Re-Drying/Conditioning temperatures of 300-350C for 1 hour. Re-drying should be restricted to a maximum of three cycles.
Warning:
Electric shock can kill
Always wear eye protection
Protect yourself and others around you
Use enough ventilation for both arc and fume source
Fumes and gases are dangerous to your health
Arc rays can injure your eyes and burn skin
