HPP 310 ALSO AVAILABLE IN:
Premium Cast Iron Mig .035, .045
GENERAL CHARACTERISTICS
Unique flux coating on alloyed core wire produces dense, strong, crack-resistant welds on all types of cast iron. Especially good for contaminated, old, oil-soaked, dirty base metal. Also recommended for joining cast iron to steel. Use on gray, ductile, Meehanite and nodular cast iron. Deposits are machinable.
TYPICAL APPLICATIONS:
Use on sewer pipe, machine bases, transmission or gear housings, sprockets, repair of or build-up on gears and any repair of cast iron to steel.

Procedure: On heavy sections, remove worn, cracked metal and bevel joint using a grinding wheel. When repairing cracks, drill "stop" holes at either end to prevent spreading while welding. On very heavy sections, preheat to approximately 4000F. Use short stringer beads for root pass and peen lightly after removing slag. Use a short to medium arc and the lowest amperage possible to minimize base metal over-heating. When breaking arc, always back whip into weld crater. Weaving two times rod diameter is acceptable for cover beads on multi-pass work. Weld joints should be allowed to cool slowly for maximum strength and machinability.
