Hobart Fabshield XLR-8 0.072 Self-Shielded Flux Core Wire 33lb

The Ultimate Outdoor Structural Wire

If you are burning rod on iron in the field, the Hobart Fabshield XLR-8 is the wire you want in your feeder. This .072-inch self-shielded flux-cored wire is built for the real world—windy decks, high steel, and tight deadlines. Forget about dragging gas cylinders up five flights of stairs or building windbreaks every time a breeze kicks up. This wire creates its own shield, letting you lay down sound welds even when the weather isn't cooperating. It is the go-to choice for structural steel erectors who need reliability and speed.

What sets the XLR-8 apart is how it handles the vertical-up pass. Traditional flux-core wires can be a fight against gravity, but this wire is formulated to freeze fast while digging deep. You can run it hotter and faster going up, stacking dimes with a flat, consistent bead profile that inspectors love. The slag system is another huge plus; in most cases, the slag practically peels itself off, saving you serious time on cleanup and reducing the risk of slag inclusions in multi-pass welds. It runs on DCEN (straight polarity), giving you a smooth, stable arc with manageable spatter levels.

This 33lb spool comes in vacuum-sealed packaging. While that sounds like technical jargon, for you it means the wire is fresh and dry the moment you crack the seal. You don't have to worry about porosity caused by humidity the wire absorbed while sitting in the truck. It's ready to run code-quality welds right out of the box. Whether you are welding column splices, beam-to-column connections, or heavy plate on a barge, this wire gives you the control and confidence to put down X-ray quality welds shift after shift.

The .072" diameter is a heavy-hitter, capable of laying down a lot of metal quickly. It is perfect for filling large bevels and heavy fillet welds found in bridge work and shipbuilding. If you are looking for a wire that works as hard as you do and helps you beat the clock on heavy structural jobs, the Hobart Fabshield XLR-8 is the industry standard for a reason.
