The Hobart Fabco Triple 7 is a gas-shielded flux-cored wire (FCAW-G) engineered to meet the demanding requirements of structural steel fabrication, shipbuilding, and heavy equipment manufacturing. Classified as E71T-1C H8 and E71T-1M H8 under AWS A5.20 standards, this wire provides a robust solution for welding carbon and higher strength steels. The 1/16" diameter variant is particularly effective for high-deposition applications on thicker base metals, allowing for increased travel speeds and fill rates compared to smaller diameter wires.
A defining feature of the Fabco Triple 7 is its fast-freezing slag system. This chemical formulation supports the weld puddle exceptionally well in out-of-position welding, specifically vertical-up progression. The slag solidifies quickly to hold the molten metal in place, allowing operators to carry a larger puddle and achieve higher deposition rates without the risk of sagging or dripping. The arc is stable and consistent, characterized by a spray-like transfer that minimizes spatter, especially when used with Argon/CO2 blends.
This wire is designed for dual-gas capability, offering operational flexibility without sacrificing mechanical integrity.
Regardless of the gas used, the Fabco Triple 7 delivers reliable impact toughness, meeting Charpy V-Notch requirements at low temperatures (typically down to -20°F or -29°C), making it suitable for structures subject to dynamic loading and cold environments.
The 600lb Exacto Pak drum is designed for high-duty cycle stations and robotic cells. The "Exacto" winding ensures tangle-free feeding, which is critical for maintaining arc stability and preventing burn-backs in automated systems. The 1/16" diameter is optimal for single and multiple pass applications on materials ranging from mild steel to fine-grain structural steels. Common applications include bridge construction, ship hull fabrication, and earthmoving equipment repair, where the combination of all-position capability and high deposition rates is essential.
