S249419-058 - Hobart Fabcor 86R 1/16" Metal-Cored Wire, 1000 lb Drum

Technical Overview of Hobart Fabcor 86R

The Hobart Fabcor 86R is a premium metal-cored arc welding wire designed to meet the rigorous demands of heavy industrial fabrication. Classified under AWS A5.18 as E70C-6M, this consumable is engineered with a specific chemical composition rich in deoxidizers, primarily silicon and manganese. This formulation provides exceptional tolerance for base metals with moderate levels of mill scale, rust, or oil, which are common in shipbuilding, railcar construction, and general structural steel fabrication. By effectively scavenging oxygen and impurities from the weld pool, the Fabcor 86R ensures sound, porosity-free welds even when surface preparation is less than optimal.

Operational efficiency is a core characteristic of the Fabcor 86R. As a metal-cored wire, it combines the high deposition rates of flux-cored wires with the high efficiency of solid wires. It operates using Direct Current Electrode Positive (DCEP) and is designed for use with Argon/CO2 shielding gas mixtures (typically 75-95% Argon). The composite metal core allows for a broader, more fluid arc cone compared to solid wires, resulting in improved sidewall fusion and a wider penetration profile. This makes it particularly effective for bridging gaps and reducing the risk of lack-of-fusion defects in fillet welds.

This specific SKU (S249419-058) is supplied in a 1000 lb Rx-Pak (Recyclable X-Pak), a bulk packaging solution tailored for high-volume manufacturing environments. The Rx-Pak utilizes a precision winding technique that ensures tangle-free feeding over long distances, which is critical for robotic cells and hard automation setups where downtime for spool changes directly impacts OEE (Overall Equipment Effectiveness). The 1/16" diameter is suitable for higher amperage applications, allowing for significant deposition rates that can exceed those of smaller diameter solid wires, thereby increasing throughput in heavy-gauge welding operations.

Mechanical properties of the deposited weld metal meet or exceed the E70C-6M requirements, offering reliable tensile strength (typically 70 ksi minimum) and impact toughness suitable for dynamic loading applications. The wire produces minimal slag in the form of small silicon islands, which are easily removed, further reducing post-weld labor costs associated with cleaning and grinding.
