Polaris – AAA

POLARIS – AAA ARC AC/DC
Shielded Metal Arc Welding All Positions
(SMAW-Stick)
For high strength alloy and problem steels such as cast steel,
Cor-Ten, nickel bearing and high grade structural steels.

FEATURES
• Excellent strength 98,000 psi
• Excellent AC stability
• Welds cast steel
• Moisture proof, low hydrogen
• Can be torch cut
• All positions
• Outstanding ductility 34% elongation
• Free machining
• Excellent sub-zero properties
• X-ray quality welds
• No undercutting
• Stable arc

CHARACTERISTICS
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 construction equipment, boilers, tanks, piping,
vehicle frames, and all crack sensitive steels. Its extraordinary ductility makes
POLARIS-AAA a good hard-surfacing pad.

APPLICATION
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 maximum weave of 2 1/2 times rod diameter. Always preheat heavy
sections.
