S246319-029 - Hobart Fabco Triple 7 1/16" Flux-Cored Wire 33lb Spool

Technical Overview of Hobart Fabco Triple 7

The Hobart Fabco Triple 7 is a premium gas-shielded flux-cored wire designed to meet the rigorous demands of structural fabrication, shipbuilding, and heavy equipment manufacturing. Engineered with a fast-freezing slag system, this wire excels in all-position welding, particularly in vertical-up applications where bead contour and puddle control are critical. The 1/16-inch diameter format in a 33-pound spool offers a balance of high deposition rates and manageability for industrial wire feeders.

Technically, the Fabco Triple 7 is formulated to conform to AWS A5.20 classifications E71T-1C and E71T-1M, as well as E71T-9C/9M. This dual classification indicates its versatility in shielding gas selection; it performs reliably with both 100% CO2 and a 75% Argon / 25% CO2 blend. The wire exhibits excellent mechanical properties, including high tensile strength and superior Charpy V-Notch impact toughness at sub-zero temperatures, making it suitable for critical applications requiring ductility and crack resistance.

The chemical composition of the flux core ensures a stable arc transfer (globular to spray type depending on parameters) with minimal spatter generation. The slag system is designed to be self-peeling or easily removable, significantly reducing non-productive time spent on chipping and grinding between passes. This wire is suitable for single and multiple pass applications on carbon and higher strength steels, providing consistent X-ray quality welds.

For industrial procurement, the S246319-029 SKU represents a standard 33lb fiber spool, compatible with most industrial wire feeders equipped with standard hubs. The wire requires knurled drive rolls to prevent deformation during feeding. Storage recommendations include maintaining a dry environment to prevent moisture pickup in the flux core, which ensures low hydrogen levels in the deposited weld metal.
