S285612-029 - Hobart Fabco 991K2 .045 Flux-Cored Wire 33lb Spool

Master High-Strength Welds with Ease

Take your welding projects to the next level with the Hobart Fabco 991K2, a flux-cored wire built for welders who need strength without the struggle. If you are working on projects that demand more than standard mild steel wire can offer—like heavy equipment repair or structural supports—this 90,000 psi tensile strength wire is your solution. The .045-inch diameter is a versatile size, perfect for bridging gaps and handling medium-to-heavy plate thicknesses with deep penetration and solid fusion.

One of the standout features of the Fabco 991K2 is its welder-friendly playability. The arc is smooth and stable, producing low spatter levels that reduce post-weld cleanup time. The slag is designed to freeze quickly, which acts as a shelf to support the puddle when you are welding vertical-up. This makes out-of-position welding significantly easier and results in a flatter, more professional-looking bead profile. The slag is also easy to remove, often peeling off with minimal effort, revealing a clean, bright weld face underneath.

Flexibility is key in the shop, and this wire delivers by running on either straight CO2 or an Argon/CO2 blend. Using a mixed gas will give you an even smoother arc and less spatter, while CO2 provides deeper penetration. With excellent Charpy V-Notch impact values at temperatures as low as -20°F, you can be confident that your welds will hold up in freezing conditions. Upgrade your spool to the Hobart Fabco 991K2 and experience the difference a premium low-alloy wire makes in your high-strength fabrication jobs.
