OVERVIEW

Hobart FabCOR 86R: The Solution for Welding Over Mill Scale

Welders Supply is proud to offer the Hobart FabCOR 86R .045" Metal Core Wire in a convenient 33lb spool, a top-tier consumable for professional fabricators who demand speed and reliability. If your shop frequently deals with hot-rolled steel covered in mill scale or light rust, this wire is engineered specifically for you. The "R" in FabCOR 86R denotes its robust formulation, packed with higher levels of silicon and manganese deoxidizers. These elements actively scavenge impurities from the weld pool, allowing you to weld directly over mill scale without sacrificing weld quality or integrity. This capability eliminates the need for extensive grinding or sandblasting before welding, saving you valuable labor hours and consumable costs.

Metal-cored wires like the FabCOR 86R are known for their incredible deposition efficiency. Because the current travels through the outer metal sheath, the wire experiences higher current density, resulting in faster melt-off rates and deeper penetration profiles compared to solid MIG wires. This means you can lay down more metal in less time, increasing your travel speeds and overall project turnaround. The 33lb spool size is an industry standard, perfectly sized for portable wire feeders and benchtop systems alike, ensuring you have enough material to keep the arc on without frequent changeovers.

The welding characteristics of FabCOR 86R are designed for operator comfort and weld quality. When used with Argon/CO2 shielding gas blends, the arc is smooth, stable, and produces very little spatter. This "spray transfer" like mode is easy to control and produces a slag-free weld face that looks professional right out of the gun. It is an excellent choice for fillet welds, lap joints, and butt welds in the flat and horizontal positions. The wire carries the AWS E70C-6M H4 classification, assuring you of its mechanical strength (70,000 psi tensile class) and low diffusible hydrogen levels, which is critical for critical structural applications.

From heavy equipment repair to railcar construction and general steel fabrication, the Hobart FabCOR 86R is a versatile workhorse. It combines the best attributes of flux-cored and solid wire welding into one high-performance package. Upgrade your welding process today with a wire that handles the dirty work so you can focus on the perfect bead. Order your 33lb spool from Welders Supply and experience the difference in productivity and quality.

FAQ

Hobart FabCOR 86R is designed to operate with Argon/CO2 shielding gas mixtures. Common blends include 75% Argon / 25% CO2 or 90% Argon / 10% CO2, which help achieve a smooth spray transfer and minimize spatter.

Yes, FabCOR 86R is specifically formulated with higher deoxidizing elements to provide excellent tolerance for welding over mill scale and light rust, reducing the need for pre-weld cleaning.

This is a metal-cored wire (AWS E70C-6M). It has a hollow metal sheath filled with metallic powders, offering high deposition rates and slag-free welds, unlike flux-cored wires which produce a slag covering.

This specific product is .045 inch (1.2 mm) in diameter.

The AWS classification is E70C-6M H4. This indicates a 70 ksi tensile strength, metal-cored electrode, mixed gas usage, and low diffusible hydrogen (H4).

Metal-cored wires like FabCOR 86R are typically designed for flat and horizontal positions due to the fluid nature of the weld pool, though out-of-position welding may be possible with pulsed waveforms or specific techniques.

Metal-cored wires produce little to no slag, often appearing as small islands of silicon that are easily removed, unlike the heavy slag coverage of flux-cored wires.

This product comes on a standard 33 lb (15 kg) spool.
