S249412-002 - Hobart FabCOR 86R .045" Metal-Cored Wire (60lb Coil)

Hobart FabCOR 86R: Superior Mill Scale Tolerance and Deposition

The Hobart FabCOR 86R is a metal-cored wire formulated to deliver superior performance in flat and horizontal welding applications. Classified as E70C-6M H4 under AWS A5.18 standards, this wire is specifically engineered to provide excellent mechanical properties while offering distinct advantages over solid wires (GMAW) and traditional flux-cored wires (FCAW). The .045-inch diameter is a versatile size, suitable for a wide range of material thicknesses commonly found in heavy equipment manufacturing, railcar construction, and structural steel fabrication.

Advanced Formulation for Dirty Steel

A primary advantage of the FabCOR 86R is its robust chemical composition, which includes elevated levels of silicon and manganese deoxidizers. These elements actively scavenge oxygen and impurities from the weld pool, making this wire exceptionally forgiving when welding over mill scale, rust, and mild surface contaminants. This feature is crucial for shops that process large volumes of hot-rolled steel where complete surface grinding is impractical. The result is a sound, porosity-free weld with excellent bead wetting and tie-in, even under less-than-ideal surface conditions.

Optimized Arc Characteristics

Welders will appreciate the soft, stable arc and low spatter generation associated with the FabCOR 86R. Unlike solid wires that can suffer from lack of fusion in certain scenarios, the composite nature of metal-cored wire creates a broader, bell-shaped penetration profile. This ensures reliable root fusion and reduces the risk of cold lap. The wire is designed to operate in the spray transfer mode using Argon/CO2 shielding gas blends (75-95% Argon), which supports high travel speeds and high deposition efficiencies (often exceeding 95%).

Efficiency and Application

The 60lb coil packaging is intended for industrial wire feeders equipped with coil adapters, offering double the wire quantity of standard 33lb spools. This reduces changeover frequency and increases arc-on time. The FabCOR 86R is also formulated to minimize silicon island formation, making inter-pass cleaning easier during multi-pass welds. With its combination of high speed, scale tolerance, and excellent weldability, the Hobart FabCOR 86R is a top-tier choice for maximizing productivity in automated and semi-automated welding operations.
