Procedures
For best results, set wire amperage
and adjust voltage for smoothest operation. Use 98% Argon-2% Oxygen
shielding gas. Wire will also operate
in the short circuiting mode or with pulse arc, and under these conditions,
may be usable out-of-position.
Observe the usual precautions on preheat,
joint preparation, and welding technique used with other cast iron
welding processes. Light peening of
each bead will reduce internal stresses and minimize cracking tendencies.
