S248819-002 - Hobart Fabco 711M 1/16" Flux-Cored Welding Wire, 60lb Coil

Technical Overview of Hobart Fabco 711M

The Hobart Fabco 711M is a premium gas-shielded flux-cored wire designed for the welding of mild and medium carbon steels. This specific SKU (S248819-002) is supplied in a 60lb coil format with a 1/16-inch (1.6mm) diameter, optimized for industrial fabrication environments requiring high deposition rates and extended welding intervals. The wire conforms to AWS A5.20 classifications E71T-1C, E71T-1M, E71T-9C, and E71T-9M, indicating its suitability for both single and multi-pass applications with stringent mechanical property requirements.

One of the defining technical characteristics of the Fabco 711M is its rutile-based slag system, which is formulated to freeze rapidly. This property is critical for supporting the weld puddle in out-of-position welding, particularly vertical-up and overhead, allowing operators to maintain higher amperage and deposition rates than typically possible with fluid slag systems. The wire exhibits a stiff arc characteristic, which enhances penetration into the base material, ensuring sound fusion even on thicker plate sections often found in shipbuilding and heavy equipment manufacturing.

Metallurgically, the wire is engineered to provide excellent low-temperature impact toughness, meeting Charpy V-Notch requirements at temperatures as low as -20°F (-29°C) or -40°F (-40°C) depending on the shielding gas used. It is dual-gas capable, operating effectively on either 100% CO2 for maximum penetration and economy, or a 75% Argon / 25% CO2 mixture for a smoother arc and reduced spatter. The 60lb coil packaging is designed for use with standard industrial wire feeders equipped with coil adapters, reducing downtime associated with spool changes in high-volume production settings.

The chemical composition and flux formulation also assist in managing hydrogen levels in the weld deposit, reducing the risk of hydrogen-induced cracking in restrained joints. This makes the Fabco 711M a reliable choice for critical structural applications where weld integrity is paramount.
