For high strength alloy and problem steels such as cast steel, Cor-Ten, nickel bearing and high grade structural steels. Polaris AAA produces sound, heat-treatable welds, even on contaminated metals. Welds have unusual strength and ductility, even at sub-zero temperatures. Welding is easy in all positions and deposits are free machining.
Applications include all mining and construction equipment, boilers, tanks, piping, vehicle frames, and all crack sensitive steels. Its extraordinary ductility makes Polaris AAA a good hard-surfacing pad. Download PDF

Best Practices
Use close arc length.
For vertical welds, lower amperage, weld from bottom up and weave.
Do not whip.
Overhead and horizontal, use stringer beads.
Down hand, weave a maximum of 2-1/2 times rod diameter.
Always preheat heavy sections.
