This electrode is made with a 55% nickel
and 45% iron core, designed for welding nodular cast iron. The deposit is sound,
crack- free and
produces good color matching on gray malleable or nodular cast iron. Proper welding
procedures should be followed. Nickel-Arc

Nickel-Arc 550 was developed with many
of the operating characteristics of the Nickel-Arc 55. The primary advantage of
this electrode
is its superior resistance to overheating, thus producing maximum deposition efficiency
during welding. The weld deposit
is smooth and flat, providing good tie-ins between stringer beads. Proper welding
procedures should be followed. Continued
