S283619-027 - Hobart Fabco 811N1 1/16" Flux-Cored Wire (50lb Spool)

High-Performance Flux-Cored Welding Wire

Hobart's Fabco 811N1 is a gas-shielded flux-cored wire that sets the standard for all-position welding of mild and low-alloy steels. This 1/16" diameter wire, supplied in a 50lb spool, is developed to provide superior weldability and mechanical performance. It carries an AWS classification typically associated with E81T1-Ni1, indicating its 1% Nickel content which significantly enhances impact toughness at sub-zero temperatures. This makes it an essential consumable for projects requiring high durability and resistance to cracking.

The Fabco 811N1 is engineered for both single and multiple pass applications. Its arc stability is notable, providing a smooth transfer that helps minimize operator fatigue during long shifts. The slag system is designed to cover the weld bead completely, protecting it from atmospheric contamination while cooling, yet it detaches easily once solidified. This feature is critical for multi-pass welds, reducing the risk of slag inclusions and ensuring high radiographic quality.

Applications for this wire are vast, ranging from heavy equipment manufacturing to general construction and shipbuilding. It is also compatible with weathering steels, offering the necessary tensile strength for structural integrity. The ability to use either straight CO2 or an Argon/CO2 mix gives welding engineers the flexibility to balance cost and arc performance. With Hobart's reputation for consistency, the Fabco 811N1 ensures that every spool delivers the same high-quality performance, weld after weld.

Technical Superiority

Welders Supply recommends the Fabco 811N1 for its exceptional operator appeal and mechanical reliability. The fast-freezing slag characteristic is perfectly balanced to allow for high deposition rates in flat positions while maintaining control in vertical-up welding. This wire represents a smart solution for shops looking to maximize efficiency without compromising on the mechanical properties of the finished weldment.
