The Hobart FabCO 811N1 is a premium 1/16-inch gas-shielded flux-cored wire designed for critical structural applications requiring superior mechanical properties. Engineered with a nominal 1% Nickel weld deposit, this wire delivers exceptional impact toughness, making it an ideal choice for industries where low-temperature notch toughness is a strict requirement. The wire meets AWS classification E81T1-Ni1CJ H4 and Ni1MJ H4, ensuring compliance with rigorous standards for high-strength low-alloy steels.
One of the standout technical characteristics of the FabCO 811N1 is its fast-freezing slag system. This feature significantly enhances puddle control, allowing operators to weld effectively in all positions, including vertical-up and overhead, without sacrificing bead quality. The formulation is optimized to produce a low hydrogen deposit (H4), which is critical for minimizing the risk of hydrogen-induced cracking in heavy structural fabrications such as bridges, offshore platforms, and heavy equipment.
This wire is particularly well-suited for welding weathering steels, such as ASTM A588 and A709, where color match is not a primary requirement but structural integrity is paramount. It offers versatility in shielding gas selection, operating efficiently with either 100% CO2 or a 75% Argon / 25% CO2 mixture. The 60 lb coil packaging is designed for industrial wire feeders, supporting high-volume production environments. With its combination of excellent slag removal, low spatter levels, and consistent arc stability, the FabCO 811N1 streamlines the welding process while delivering X-ray quality welds.
