S246312-029 - Hobart FabCO Triple 7 .045 Gas-Shielded Flux-Core 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. Engineered with a diameter of 0.045 inches (1.2 mm) and supplied on a 33 lb (15 kg) spool, this tubular wire is formulated for joining carbon and higher strength steels. It is characterized by its broad versatility, carrying multiple AWS classifications including E71T-1C/M, E71T-9C/M, and E81T1-GC/-GM. This multi-classification capability ensures that the wire meets specific mechanical property requirements for tensile strength and impact toughness across various applications.

One of the primary technical advantages of the FabCO Triple 7 is its adaptability to different shielding gases. It performs exceptionally well with both 100% CO2 and a blend of 75% Argon / 25% CO2. This flexibility allows fabrication shops to optimize their gas selection based on cost, availability, or specific arc characteristic preferences without switching consumables. The wire utilizes a fast-freezing slag system, which significantly enhances puddle control during out-of-position welding, particularly in vertical-up and overhead orientations. This makes it an ideal choice for complex structural assemblies where rotating the workpiece is not feasible.

Mechanically, the wire provides high impact strengths at low temperatures, a critical factor for industries such as shipbuilding and offshore construction where weld ductility is paramount. The formulation also focuses on operator environment and efficiency; it generates lower fume levels compared to many conventional flux-cored wires in its class. The resulting weld deposit exhibits excellent radiographic quality, ensuring compliance with stringent code requirements. Whether utilized in single-pass or multi-pass applications, the FabCO Triple 7 delivers consistent penetration and fusion, making it a reliable consumable for heavy equipment manufacturing, railcar fabrication, and general structural steel projects.
