Hobart FabCO XL-550 1/16" Flux-Cored Wire, 600lb Drum

Superior Playability and Impact Toughness for Professional Welders

The Hobart FabCO XL-550 1/16" Flux-Cored Wire is built for welders who demand consistency, control, and high-quality results in challenging environments. As an AWS E71T-1 and E71T-9 classified wire, the XL-550 is a go-to consumable for critical code work where mechanical properties cannot be compromised. This wire is specifically renowned for its ability to maintain high impact values at temperatures as low as -40°F, giving you the confidence that your welds will hold up under extreme stress and environmental conditions. Whether you are welding structural beams, storage vessels, or repairing heavy mining equipment, the XL-550 provides the assurance of a sound, ductile deposit.

From an operator's perspective, the FabCO XL-550 offers excellent "playability." The arc is smooth and stable, with a spray-type transfer that minimizes spatter, keeping your workpiece cleaner and improving visibility during the weld. One of the most appreciated features is the slag system; the slag coverage is complete but detaches easily—often peeling up on its own as it cools. This significantly reduces the time and effort spent on chipping and grinding between passes, allowing you to maintain a high duty cycle and focus on laying down metal. The 1/16-inch diameter supports higher deposition rates for filling large joints quickly, yet the wire remains controllable enough for out-of-position work when parameters are optimized.

The 600lb Exacto Pak drum is designed for stationary shop setups, providing a straight, twist-free wire path that reduces feeding issues common with smaller spools. This wire runs effectively on 100% CO2, which provides deep penetration and cost savings, but it also performs exceptionally well with 75% Argon / 25% CO2 blends for an even smoother arc and reduced fume generation. With its low hydrogen designation, the FabCO XL-550 helps you avoid hydrogen-induced cracking, a critical factor when welding on thicker plates or restrained joints. When your job requires a wire that balances ease of use with heavy-duty performance specs, the Hobart FabCO XL-550 is the professional's choice.
