The Hobart FabCO 811N1 is a premium gas-shielded flux-cored wire designed for critical structural applications requiring superior toughness. Engineered with a nominal 1% Nickel weld deposit, this wire excels in environments where low-temperature impact properties are essential. It meets the AWS E81T1-Ni1CJ H4 and Ni1MJ H4 classifications, making it a robust choice for industries ranging from bridge fabrication to shipbuilding. The wire is formulated to provide a low hydrogen deposit (H4), significantly reducing the risk of hydrogen-induced cracking in high-strength low-alloy (HSLA) steels.
One of the standout features of the FabCO 811N1 is its fast-freezing slag system. This characteristic allows welders to perform single and multi-pass welds in all positions—flat, horizontal, vertical-up, and overhead—without sacrificing bead contour or quality. The slag is designed for easy removal, often peeling off with minimal effort, which reduces inter-pass cleaning time and improves overall productivity. Additionally, the wire produces low spatter levels, ensuring a cleaner work environment and less post-weld grinding.
Flexibility in shielding gas selection is a key advantage of the FabCO 811N1. It performs exceptionally well with both 100% CO2 and a 75% Argon / 25% CO2 gas mixture. This versatility allows fabrication shops to utilize existing gas supplies without needing specialized mixtures, while still achieving the desired mechanical properties. Whether used for heavy equipment fabrication, structural steel projects, or pipeline construction, this wire delivers consistent, high-quality results. It is also suitable for welding weathering steels (such as ASTM A588 and A709) in applications where a specific color match is not a requirement.
Packaged in a 33 lb spool, this .045" diameter wire is ideal for industrial wire feeders and prolonged welding sessions. Its consistent feeding properties and stable arc make it a favorite among professional welders in the petro-chemical, mining, and power generation sectors. By choosing Hobart FabCO 811N1, you are investing in a consumable that offers a balance of mechanical strength, operational playability, and reliable performance in demanding conditions.
