Polaris Ultra Flux Core Wire – .035" Self-Shielded FCAW for Structural and Heavy Equipment Welding - 2lb Spool
Product Description
Rugged, reliable flux-core welding—no gas required.
Polaris Ultra Flux Core .035" is a self-shielded, all-position flux-core wire built for structural steel, heavy equipment, tanks, and field repairs. Designed for harsh conditions and out-of-position welding, it produces x-ray quality welds with low spatter, smooth transfer, and excellent arc stability—even in drafts.
With a tensile strength of 95,000 psi and 28% elongation, Polaris Ultra Flux Core is ideal for maintenance and fabrication environments where shielding gas isn’t feasible. It handles rust, oil, and mill scale thanks to built-in deoxidizers and is perfect for use with suitcase wire feeders.
