OVERVIEW

Reliable All-Position Welding for Heavy Fabrication

When your project demands durability and precision, the Hobart FabCO 811N1 1/16" Flux-Cored Wire delivers the performance professional welders trust. This 60 lb coil is formulated to tackle the toughest jobs, from bridge fabrication to heavy earthmoving equipment repair. If you are working with high-strength low-alloy steels or weathering steels, this wire provides the mechanical strength and impact toughness needed to ensure welds hold up under extreme stress and low temperatures.

Welders will appreciate the excellent operator appeal of the FabCO 811N1. The wire features a fast-freezing slag that supports the weld puddle perfectly, making out-of-position welding—like vertical-up or overhead—much easier to manage compared to standard wires. Additionally, the low spatter formulation means you spend less time grinding and cleaning up after the weld is laid, and more time moving on to the next joint. The slag is designed to peel off easily, revealing a smooth, professional bead profile that inspires confidence.

Versatility is a core benefit of this product. Whether you are using straight CO2 for deep penetration and economy, or a 75/25 Argon/CO2 mix for a smoother arc, the FabCO 811N1 adapts to your shop's setup. It is specifically engineered to provide low hydrogen deposits, which is a crucial factor in preventing cracking in thick materials and critical structures. For shipyards, structural steel erection, and heavy manufacturing, this wire combines ease of use with industrial-grade reliability.

Benefits for the Welder:

  • All-Position Capability: Weld flat, horizontal, vertical, or overhead with ease.
  • Clean Finishes: Low spatter and easy slag removal reduce post-weld cleanup time.
  • Tough Welds: 1% Nickel content ensures welds resist cracking even in cold environments.
  • Versatile Gas Use: Compatible with both CO2 and Mixed gases.

FAQ

The AWS classification is E81T1-Ni1CJ H4 and Ni1MJ H4.

This wire can be used with 100% CO2 or a mixture of 75% Argon and 25% CO2.

Yes, the FabCO 811N1 features a fast-freezing slag that makes it excellent for all-position welding, including vertical-up and overhead.

The wire diameter is 1/16 inch.

It is primarily used for high-strength low-alloy steels, bridge fabrication, shipbuilding, and weathering steels where low-temperature toughness is required.

No, while it is suitable for welding weathering steels like ASTM A588, it is used when color match is not required.

This product comes in a 60 lb coil.

H4 indicates that the wire produces a low hydrogen deposit (less than 4ml of diffusible hydrogen per 100g of weld metal), reducing the risk of hydrogen-induced cracking.
