Hobart Fabco Triple 7 .045 FCAW Wire 50lb

Technical Performance: Hobart Fabco Triple 7

Hobart Fabco Triple 7 is a gas-shielded flux-cored wire (FCAW-G) formulated to meet AWS E71T-1C and E71T-1M specifications. This .045-inch diameter wire is supplied on a 50lb spool and is specifically designed for single and multiple pass applications on carbon and low-alloy steels. It is characterized by a rutile-based slag system that provides a fast-freezing puddle, making it an excellent candidate for out-of-position welding, particularly vertical-up and overhead, where puddle fluidity can often be a challenge.

Arc Characteristics and Mechanical Properties

Welders will appreciate the smooth, stable arc that the Fabco Triple 7 produces. The wire is formulated to deliver high impact values at low temperatures (typically down to -20°F or -40°F depending on the gas used), ensuring the structural integrity of the weldment in harsh environments. The bead profile is generally flat to slightly convex, providing good tie-in at the toes of the weld. With low spatter levels and a slag that often peels off by itself or with light chipping, this wire reduces operator fatigue and cleanup time.

Shielding Gas Versatility

This consumable is dual-classified, meaning it maintains its mechanical properties and runnability under both 100% Carbon Dioxide (CO2) and a blend of 75% Argon / 25% CO2. Using 100% CO2 provides deeper penetration and is cost-effective, while the Argon blend offers a smoother arc and reduced spatter. This flexibility makes the Fabco Triple 7 a strategic inventory choice for shops that perform diverse fabrication tasks ranging from shipbuilding and railcar construction to general plate fabrication.
