Hobart FabCO® XL-525 .045" Gas Shielded Flux-Cored Wire

The Hobart FabCO® XL-525 is a premium .045-inch gas-shielded flux-cored wire designed to meet the rigorous demands of heavy industrial fabrication. Packaged in a 33 lb spool, this wire is engineered for carbon steel welding applications where impact toughness at lower temperatures is critical. It carries the AWS classifications E71T-1MJ, E71T-9MJ, and E71T-12MJ H8, signifying its superior mechanical properties and low hydrogen content. This makes it an exceptional choice for industries requiring high-integrity welds, such as shipbuilding, offshore platform construction, and heavy equipment manufacturing.

One of the standout features of the FabCO XL-525 is its all-position capability. Whether welding flat, horizontal, vertical-up, or overhead, operators experience a stable, consistent arc that is easy to control. The wire is formulated to operate specifically with a shielding gas mixture of 75% Argon and 25% CO2. This blend assists in producing a smooth spray-like transfer with minimal spatter, reducing post-weld cleanup time. The slag system is designed for easy removal, often peeling away to reveal a clean, high-quality bead profile.

Safety and durability are paramount in structural welding, and the XL-525 delivers with its H8 low-hydrogen designation. By maintaining diffusible hydrogen levels below 8ml per 100g of weld metal, this wire significantly minimizes the risk of hydrogen-induced cracking (cold cracking), which is vital when working with thicker steel sections or restrained joints. Its formulation ensures excellent Charpy V-Notch impact values even in sub-zero environments, providing peace of mind for projects exposed to harsh weather conditions.

This wire is suitable for both single and multiple pass applications, making it versatile for various joint configurations. From general fabrication to specialized pressure vessel construction, the Hobart FabCO XL-525 offers the reliability and performance professional welders expect from the Hobart brand.
