Hobart Fabco 115: Premium High-Strength Flux-Cored Wire

The Hobart Fabco 115 is a specialized gas-shielded flux-cored wire designed for the most demanding structural and heavy equipment applications. Engineered with a basic slag system, this wire delivers weld deposits that rival the mechanical integrity of low-hydrogen stick electrodes (such as E11018), but with the deposition rates and efficiency of a continuous wire process. It is specifically formulated for welding quenched and tempered high-strength low-alloy (HSLA) steels, including T-1, A514, A517, and HY-100 grades, where maintaining high tensile strength and ductility is critical.

One of the standout features of the Fabco 115 is its exceptional resistance to cracking. The basic slag formulation produces a very low hydrogen weld deposit (typically under 4ml/100g), which is essential when welding thick sections or highly restrained joints often found in mining and earthmoving equipment. This wire provides excellent impact toughness at low temperatures, ensuring the structural integrity of welds even in harsh operating environments. While the basic slag system may produce a more convex bead profile and slightly more spatter than rutile wires, the trade-off is a metallurgically superior weld metal suitable for critical safety components.

This .045-inch diameter wire comes on a 33lb spool and is designed for flat and horizontal welding positions. It offers flexibility in shielding gas selection, operating effectively with either 100% CO2 or a 75% Argon / 25% CO2 blend. The mixed gas option generally provides a smoother arc and reduced spatter. Whether you are repairing heavy mining excavators, fabricating crane booms, or working on off-road vehicle chassis, the Hobart Fabco 115 provides the reliability and strength required for heavy-duty industrial fabrication.
