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

Master Dirty Steel with Hobart FabCOR 86R

Stop wasting valuable time grinding away every inch of mill scale before you strike an arc. The Hobart FabCOR 86R .052" Metal-Cored Welding Wire is built to handle the reality of industrial welding. Unlike standard solid wires that require pristine surface preparation, the FabCOR 86R features a special chemical formulation loaded with deoxidizers. This allows it to burn through light-to-moderate rust, mill scale, and oil, pulling impurities to the surface in small silicon islands rather than trapping them as porosity in your weld. The result is a sound, X-ray quality weld with minimal prep work.

This 44lb spool is designed for serious fabricators who need to keep the arc on. Metal-cored wires like the FabCOR 86R offer a significant productivity boost over solid MIG wire. Because the current travels through the outer metal sheath, you get a higher current density that melts the wire faster. This means you can weld with faster travel speeds and lay down more metal per hour. It’s the perfect solution for long, continuous welds found in railcar manufacturing, barge building, and structural steel fabrication.

Smooth Operation and Great Bead Appearance

Welders love the FabCOR 86R for its smooth runability. When paired with a 75/25 or 90/10 Argon/CO2 gas mix, this wire operates in a spray transfer mode that feels soft and consistent. You will experience very little spatter, which means you won't be spending your afternoon chipping BBs off your workpiece. The weld bead wets out beautifully, creating a flat, professional-looking profile that blends smoothly into the base metal. Unlike flux-cored wires, there is no heavy slag layer to chip off—just small islands of silica that often pop off on their own or brush away easily.

The .052" diameter is a sweet spot for heavy plate welding, offering deep penetration and high fill rates without being unmanageable. Whether you are welding fillets on heavy machinery or butt joints on storage tanks, Hobart FabCOR 86R gives you the speed of a cored wire with the cleanliness of a solid wire.
