Hobart Fabco XL-550 .052" Flux-Cored Wire 33lb Spool

Hobart Fabco XL-550: Performance You Can Trust

When your job demands a weld that stands up to the toughest conditions, reach for the Hobart Fabco XL-550. This .052-inch flux-cored wire is a favorite among professional welders for its smooth runability and forgiving arc. Whether you are welding structural steel beams, repairing heavy mining equipment, or working in a shipyard, the Fabco XL-550 delivers consistent, high-quality results. The "XL" stands for extra low hydrogen and extra low temperature impact properties, giving you peace of mind that your welds are strong, ductile, and crack-resistant even in freezing environments.

One of the biggest advantages of this wire is its all-position capability. Vertical-up welds are made easier thanks to a fast-freezing slag system that holds the puddle in place, preventing sagging and minimizing the need for extensive grinding later. Speaking of grinding, the slag on the Fabco XL-550 is designed to peel off easily—often curling up on its own—saving you valuable time on cleanup. The low spatter formulation further reduces post-weld cleaning, allowing you to move on to the next pass or the next joint faster.

This 33lb spool comes vacuum-packed, ensuring the wire is fresh and free from moisture contamination the moment you open it. It runs beautifully on 100% CO2, which keeps your gas costs down, but can also handle mixed gas if your procedure requires it. If you are looking for a wire that combines high deposition rates with the versatility to weld in any position, the Hobart Fabco XL-550 is the reliable workhorse you need in your wire feeder.
