Hobart FabCO XL-550: Premium Flux-Cored Wire for Critical Applications

The Hobart FabCO XL-550 .045" 33lb Spool is a high-performance gas-shielded flux-cored wire designed to meet the rigorous demands of heavy industrial fabrication. Engineered for excellence, this wire provides superior mechanical properties, specifically delivering outstanding impact toughness at low temperatures. This makes it a preferred choice for industries such as shipbuilding, offshore construction, and heavy equipment manufacturing where structural integrity in harsh environments is paramount.

One of the defining characteristics of the FabCO XL-550 is its low hydrogen formulation (H8), which significantly minimizes the risk of hydrogen-induced cracking in thick structural steel sections. It is classified under AWS E71T-1C/1M and E71T-9C/9M, ensuring compliance with strict industry standards. The wire is versatile enough to be used with either 100% CO2 or a 75% Argon / 25% CO2 gas mixture, giving fabricators flexibility based on their available gas supply and desired arc characteristics.

This wire excels in both single and multiple pass applications across all welding positions. Whether welding vertical-up on a ship hull or flat on a structural beam, the FabCO XL-550 maintains a stable arc and consistent bead profile. Its high deposition efficiency helps improve throughput in production environments, reducing downtime and increasing overall project efficiency. For professionals seeking a reliable, high-impact wire that performs consistently under pressure, the Hobart FabCO XL-550 is the industrial standard.
