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

Burn Through Mill Scale with Fabcor 86R

If you are welding heavy structural steel, railcars, or ship components, you know that perfect surface preparation isn't always possible. Grinding every inch of mill scale takes time and kills productivity. That is where Hobart Fabcor 86R steps in. This 1/16-inch metal-cored wire is formulated specifically to handle dirty steel. It has extra deoxidizers that act like cleaning agents in the weld puddle, floating out impurities from rust and scale so you don't end up with porosity or worm tracks. It allows you to weld over mill scale that would cause a solid MIG wire to sputter and fail, saving you hours of prep time on large projects.

The "Metal Core" difference is something you will feel under the hood. Unlike standard flux-cored wire, Fabcor 86R doesn't leave a heavy slag covering that you have to chip off. You get a clean, smooth bead with just a few small glass-like islands of silicon that often pop off on their own or brush away easily. The arc is soft, stable, and sprays smoothly, giving you excellent control and wetting action. Because the current travels through the outer sheath of the wire, you get higher current density, which means you can travel faster and lay down more metal per hour than you could with a standard solid wire.

This product comes in a massive 1000 lb Rx-Pak. While you will need a forklift to move it, the advantage is that you can weld for days or weeks without stopping. For shops running continuous beads on long girders or using welding automation, this bulk pack is a game-changer. You aren't stopping every few hours to swap out a 33lb spool and re-thread your machine. It feeds smoothly right out of the drum, designed to prevent tangles that stop production.

Fabcor 86R runs on standard CV power sources with Argon/CO2 blends (usually 75/25 or 90/10). It is designed for flat and horizontal welding, making it perfect for long fillet welds on heavy plate. If you are looking to boost your travel speeds, reduce your grinding time, and keep your arc on longer, this is the wire to load into your feeder.
