S281612-029 - Hobart Fabcor 90 Metal-Cored Wire .045 33lb Spool

Superior Strength and Playability for Heavy Fabrication

When your project demands welds that can withstand extreme stress and heavy loads, the Hobart Fabcor 90 .045" metal-cored wire is the filler metal you need in your feeder. Designed for the professional welder tackling high-strength steels, this wire offers a distinct advantage over standard solid wires: speed and deposition. Because it is a metal-cored wire, the current travels through the outer sheath, creating a broader, cone-shaped arc that wets out smoothly and penetrates deep. This results in faster travel speeds and a flatter bead profile, reducing the amount of post-weld grinding and cleanup required.

The Fabcor 90 runs on a mixed gas blend of 75-95% Argon and CO2, which helps produce a smooth, stable arc with minimal spatter. This makes it a pleasure to run, even during long shifts on demanding jobs like shipbuilding or heavy equipment repair. Whether you are welding thick plate for an offshore platform or fabricating the boom of a crane, this wire provides the confidence that your welds will hold up under pressure. It handles both single and multi-pass welds with ease, ensuring excellent fusion and sidewall tie-in, which is critical when working on pressure vessels or structural castings.

Packaged in a standard 33lb spool, this wire is ready to load into your shop's wire feeder for extended runs. The .045" diameter is a perfect middle-ground size, offering high deposition for thick materials while remaining manageable for positional work if needed (though metal core is best in flat/horizontal). If you are used to fighting with slag or dealing with the slow deposition of solid wire on heavy steel, switching to Fabcor 90 will feel like a significant upgrade in both productivity and weld quality.
