S245119-002 - Hobart Fabco XL-550 1/16" Flux-Cored Welding Wire, 60lb Coil

Superior Arc Control with Hobart Fabco XL-550

When your weld quality determines the structural integrity of a vessel or building, you need a wire that performs without compromise. The Hobart Fabco XL-550 1/16" flux-cored wire is built for welders who demand excellent runnability and superior mechanical properties. This wire is formulated to provide a smooth, stable arc with low spatter levels, giving you better control over the puddle and significantly reducing post-weld cleanup time. Whether you are running straight CO2 or a 75/25 Argon mix, the XL-550 delivers a consistent bead profile with deep penetration.

One of the standout features of the Fabco XL-550 is its slag release. Welders know that fighting stubborn slag slows down production and increases the risk of inclusions in multi-pass welds. This wire features a fast-freezing slag that often peels up by itself or removes easily with a light scrape, revealing a clean, bright weld face. This characteristic is particularly beneficial when welding in vertical-up or overhead positions, where slag control is crucial for preventing drips and maintaining bead shape.

Technically, this wire is a powerhouse. It offers high impact toughness at low temperatures (Charpy V-Notch), making it suitable for critical applications like earth-moving equipment repair, bridge construction, and storage vessel fabrication. The low hydrogen content helps ensure your welds remain crack-free, even on challenging steels. With the 60lb coil, you have plenty of material to tackle large jobs without constant spool changes, allowing you to focus on laying down perfect beads.
