Hobart Fabcor 86R .052 Metal-Cored Wire Overview

The Hobart Fabcor 86R is a premium metal-cored arc welding (MCAW) wire designed to deliver high-performance results in general fabrication and heavy industrial applications. Classified as E70C-6M H4 under AWS A5.18 standards, this wire is engineered with a higher level of deoxidizing elements (silicon and manganese) than standard metal-cored wires. This chemical composition provides exceptional tolerance for welding over mill scale, rust, and other surface contaminants, making it a preferred choice for structural steel and railcar manufacturing where pre-weld cleaning must be minimized.

This .052-inch diameter wire is packaged in a 50-pound spool, suitable for industrial wire feeders. It operates using a shielding gas mixture of 75% to 95% Argon with the balance being CO2. The high Argon content promotes a stable, spray-transfer-like arc that produces minimal spatter and virtually no slag, significantly reducing post-weld cleanup time. The Fabcor 86R is capable of both single and multiple pass welds, primarily in the flat and horizontal positions, offering high deposition rates that can improve overall production throughput.

Technical specifications indicate a tensile strength consistent with the 70 ksi class, ensuring robust weld integrity. The "H4" designation signifies a low diffusible hydrogen content (less than 4ml per 100g of weld metal), which is critical for preventing hydrogen-induced cracking in heavy plate applications. By combining high travel speeds with deep penetration profiles, the Fabcor 86R serves as an efficient solution for automated and semi-automated welding environments.
