S249415-044 - Hobart FabCOR 86R .052 Metal Core Wire 44lb Spool

High-Performance Metal-Cored Wire for Industrial Fabrication

The Hobart FabCOR 86R .052" Metal-Cored Welding Wire is a premium consumable designed to address the specific challenges of heavy industrial manufacturing. Engineered with a composite metal-cored structure, this wire combines the high deposition efficiency of flux-cored wires with the high travel speeds and clean finish of solid wires. The "86R" formulation is distinctively enriched with higher levels of deoxidizing elements, such as silicon and manganese. This chemical composition provides exceptional tolerance for contaminants, making it the ideal choice for welding over mill scale, rust, and primers without sacrificing weld quality or mechanical integrity.

Classified as E70C-6M H4 under AWS standards, the FabCOR 86R delivers consistent mechanical properties with a tensile strength typically exceeding 70,000 psi. It is designed for use with Argon-rich shielding gas mixtures (typically 75% to 95% Argon with a CO2 balance), which promotes a stable spray transfer mode. This results in a soft, smooth arc with virtually no spatter, significantly reducing post-weld cleaning time and abrasive costs. The 44lb spool size is optimized for industrial wire feeders, providing a substantial amount of material to minimize changeover downtime in high-volume production environments.

Technical Advantages & Efficiency

For fabrication shops looking to increase throughput, the FabCOR 86R offers higher deposition rates than comparable solid wires of the same diameter. The tubular design increases current density at the arc, leading to faster melt-off rates and deeper penetration profiles. This wire excels in single and multi-pass applications, particularly in the flat and horizontal positions. Its fluid puddle characteristics ensure excellent wetting at the toes of the weld, reducing the likelihood of cold lap and stress risers. Furthermore, the low hydrogen designation (H4) ensures that the weld deposit is resistant to hydrogen-induced cracking, a critical factor in structural steel and heavy equipment manufacturing.

Whether utilized in robotic automation or semi-automatic handheld welding, the Hobart FabCOR 86R provides the reliability and performance required for critical welds in shipbuilding, railcar construction, and general heavy fabrication. Its ability to bridge gaps and handle imperfect surface conditions makes it a versatile asset in any professional welding operation.
