All-State Super 4-60®
Unique electrode for cast iron, ductile
iron and dissimilar metals. Does not overheat. AC/DC
Straight or Reverse General
Characteristics This
machinable alloy formulation designed for critical cast iron repairs produces
extraordinary crack resistant deposits.
Super 4-60®
offers such performance qualities as: superior weldability; excellent wash and
fluidity;
strong,
quiet, yet spatter free arc; no overheating at rated amperages thus no flux
breakdown which can produce
porosity
and inclusions in the weld deposit; consistent and reliable welds.
Typical Applications
Heavy cast iron machine bases, pump
and differential housings: build up applications on cast iron dies, cylinder
heads, engine blocks, heavy equipment
parts, gear teeth, sprockets; joining cast and ductile iron to steel and
cast iron pipe/flanges, housings.

Clean weld area. Vee cracks using All-State®
Chamfer Rod. Critical applications require preheating of 500°-600°F
(260°-316°C).
Maintain this temperature throughout entire welding operation. Peen lightly after
each weld bead. Remove
all slag between passes. Use a skip welding technique. Upon completion, cover
casting and allow it to
cool slowly.
