When your welding project demands more than just a standard mild steel wire, the Hobart Fabco 91K2-M delivers the strength and performance you need. This .045-inch flux-cored wire is built for high-strength applications, offering a 90,000 psi tensile strength that stands up to the harshest conditions found in offshore rigs, heavy construction equipment, and structural steel fabrication. If you are welding high-strength low-alloy steels, this is the wire that ensures your welds are as tough as the base metal.
Welders will appreciate the smooth runability of the Fabco 91K2-M. Designed for use with 75/25 mixed gas, it produces a stable arc with minimal spatter, keeping your workpiece clean and your vision clear. The fast-freezing slag supports the puddle perfectly, making out-of-position welds—like vertical-up or overhead—much easier to control compared to fluid slag systems. The slag peels off easily, revealing a smooth, professional bead profile that requires little grinding.
This 10 lb spool is perfect for portable suitcase feeders or smaller jobs where lugging a heavy 33 lb spool isn't practical. Whether you are repairing an excavator boom in the field or fabricating structural beams in the shop, the Fabco 91K2-M gives you the confidence that your welds will hold up under stress and low temperatures. It’s the professional's choice for high-stakes welding where quality cannot be compromised.
