S249415-029 - Hobart FabCOR 86R .052 Metal-Cored Wire 33lb Spool

High-Efficiency Metal-Cored Wire for Industrial Fabrication

The Hobart FabCOR 86R .052" Metal-Cored Wire is a premium choice for industrial manufacturers seeking to optimize their welding operations. Supplied in a standard 33lb spool, this wire is engineered to address common challenges in heavy fabrication, particularly when dealing with less-than-perfect base materials. Unlike standard solid wires, the FabCOR 86R features a composite metal-cored design packed with higher levels of deoxidizing elements. This unique formulation allows the wire to penetrate through mill scale, rust, and oil more effectively, significantly reducing the need for extensive pre-weld cleaning and grinding. For industries like shipbuilding and railcar manufacturing, where material preparation can be a major bottleneck, this capability translates directly to time and labor savings.

In addition to its surface tolerance, the FabCOR 86R is designed for high productivity. The metal-cored structure allows for higher current densities, resulting in faster travel speeds and higher deposition rates compared to solid ER70S-6 wires. This makes it an excellent solution for automatic and robotic welding cells where cycle time is critical. The wire operates smoothly with Argon/CO2 shielding gas mixtures, typically in the range of 75% to 95% Argon, providing a stable arc that is easy to control. The resulting weld beads are flat and smooth with excellent wetting into the toes of the weld, minimizing stress concentrations and improving fatigue life in dynamic structures.

Josef Gas recommends this wire for general fabrication shops looking to upgrade from solid wire to a higher-performance consumable. The 33lb spool fits standard wire feeders, making the switch seamless. Whether you are welding structural steel beams, heavy equipment chassis, or railcars, the Hobart FabCOR 86R delivers the consistency and quality required for code-compliant welding. Its ability to bridge gaps better than solid wire also aids in situations where fit-up is not perfect, reducing rework and burn-through.
