S283715-056 - Hobart FabCO 803 .052 Flux-Cored Wire 600lb Drum

Technical Overview of Hobart FabCO 803

The Hobart FabCO 803 is a premium gas-shielded flux-cored wire designed to meet the rigorous demands of industries requiring high-strength welds with exceptional low-temperature toughness. Specifically engineered for joining fine-grained steels and 2% Nickel steels, this wire conforms to AWS E81T1-Ni2C and E81T1-Ni2M classifications. It is an ideal choice for critical structural applications where mechanical integrity at sub-zero temperatures is paramount. The wire diameter is .052 inches, offering a balance of deposition rate and puddle control suitable for medium-to-heavy plate fabrication.

Metallurgically, FabCO 803 provides a deposit composition that ensures consistent impact properties. The fast-freezing slag system is a key technical feature, allowing operators to weld in all positions—including vertical-up and overhead—without sacrificing bead profile or quality. This versatility makes it highly adaptable to complex joint configurations found in offshore and pipeline projects. The wire is formulated to operate effectively with both 100% CO2 and mixed gases (75-80% Argon / Balance CO2), providing flexibility depending on the available gas supply and desired arc characteristics. Using mixed gas typically yields a smoother arc and slightly higher tensile strengths.

This specific SKU (S283715-056) is supplied in a 600 lb Exacto Pak. This bulk packaging solution is designed for high-volume manufacturing environments, significantly reducing the frequency of spool changes and associated downtime. The Exacto Pak ensures a tangle-free feed, which is critical for automated or semi-automated welding cells where arc-on time is a key performance indicator. The wire exhibits low spatter levels and easy slag release, further enhancing operational efficiency by minimizing post-weld cleaning requirements.
