S246315-023 - Hobart Fabco Triple 7 0.052" 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 industrial fabrication. Identified by the internal SKU S246315-023, this 0.052-inch diameter wire is packaged in a 33 lb (15 kg) fiber spool, making it compatible with standard industrial wire feeders. It is formulated to provide excellent mechanical properties and operator appeal across a wide range of applications.

Technically, Fabco Triple 7 is classified under AWS A5.20 as E71T-1C H8 and E71T-1M H8. This dual classification indicates its versatility in shielding gas selection; it performs exceptionally well with both 100% CO2 and a blend of 75% Argon / 25% CO2. The wire features a rutile-based slag system that is fast-freezing, which is critical for supporting the weld puddle in out-of-position welding, particularly vertical-up and overhead. This characteristic allows for higher deposition rates in position compared to wires with slower freezing slag.

From a metallurgical perspective, the wire deposits weld metal with low diffusible hydrogen (H8 designation), typically less than 8ml per 100g of weld metal. This reduces the susceptibility to hydrogen-induced cracking (cold cracking), a vital factor when welding thicker sections of carbon and higher strength steels. The deposit also exhibits high impact toughness, meeting Charpy V-Notch requirements at temperatures as low as -20°F (-29°C), making it suitable for structural applications subject to dynamic loading and low service temperatures.

The wire is engineered for single and multiple pass applications. It provides deep penetration and consistent fusion, mitigating common defects such as lack of fusion or slag inclusions. The arc characteristics are smooth and stable, with a spray-like transfer mode that minimizes spatter generation. This efficiency in metal transfer translates to higher deposition efficiency and reduced consumable waste.
