S689119-078 - Hobart Fabco 308LT1-1/4 Stainless Flux-Cored Wire 1/16" 27.5lb

Technical Overview of Hobart Fabco 308LT1-1/4

The Hobart Fabco 308LT1-1/4 is a premium gas-shielded flux-cored arc welding (FCAW) wire designed for the joining of austenitic stainless steels. Specifically formulated to meet AWS A5.22 classifications E308LT1-1 and E308LT1-4, this consumable offers versatility in shielding gas selection, operating effectively with either 100% CO2 or a blend of 75% Argon and 25% CO2. The 'L' designation indicates a low carbon content (maximum 0.04%), which is critical for preventing carbide precipitation and ensuring resistance to intergranular corrosion in the as-welded condition.

This wire features a rutile-based slag system that provides a fast-freezing slag, enabling all-position welding capabilities, including vertical-up and overhead, without the need for pulsed arc equipment. The 1/16-inch (1.6mm) diameter allows for higher current carrying capacities and deposition rates compared to smaller diameters, making it suitable for medium-to-heavy fabrication of 304 and 304L stainless grades. The flux composition is engineered to produce a flat to slightly convex bead profile with fine ripples, ensuring high aesthetic quality and reducing the need for post-weld grinding.

Metallurgically, the deposit provides excellent mechanical properties and corrosion resistance matching that of the base metal. It is widely utilized in industries requiring robust stainless fabrication, such as chemical processing, food and beverage equipment manufacturing, and cryogenic vessel construction. The wire is precision-wound on a 27.5 lb spool, ensuring consistent feedability and arc stability throughout the welding operation.
