S279519-029 - Hobart FabCOR Edge Ni1 1/16" Metal-Cored Welding Wire 33lb Spool

Technical Overview of Hobart FabCOR Edge Ni1

The Hobart FabCOR Edge Ni1 is a premium metal-cored arc welding wire designed to meet the rigorous demands of high-strength, low-alloy (HSLA) steel fabrication. This specific spool features a 1/16-inch (1.6mm) diameter and is supplied in a 33lb (15kg) package. It is engineered to conform to AWS A5.28 classifications, specifically E80C-Ni1, making it the ideal choice for applications requiring superior mechanical properties, particularly impact toughness at sub-zero temperatures.

The "Ni1" designation indicates a nominal 1% nickel content, which is critical for maintaining ductility and toughness in cold environments, typically down to -40°F (-40°C). This metallurgical composition makes the FabCOR Edge Ni1 suitable for welding nickel-molybdenum steels and weathering steels where color match is not the primary concern but structural integrity is paramount. The wire is formulated to operate with mixed shielding gases, providing optimal performance with either 75% Argon / 25% CO2 or 98% Argon / 2% Oxygen mixtures. The use of high-argon mixtures facilitates a smooth spray transfer mode, significantly reducing spatter and fume generation compared to conventional flux-cored or CO2-shielded processes.

From a productivity standpoint, this metal-cored wire offers distinct advantages over solid wires. The composite nature of the wire allows for higher current densities at equivalent amperage settings, resulting in higher deposition rates and faster travel speeds. This efficiency is crucial for heavy fabrication sectors such as mining, railcar manufacturing, and heavy equipment construction. Furthermore, the FabCOR Edge Ni1 exhibits excellent wetting characteristics, ensuring smooth tie-ins at the toes of the weld and reducing the risk of cold lap or lack of fusion. The resulting weld bead is clean with minimal slag—typically manifesting only as small, easily removable silicon islands—which reduces post-weld cleaning time and labor costs.

This product is also characterized by its low hydrogen levels (typically H4 designation), minimizing the risk of hydrogen-induced cracking in thick sections or restrained joints. It is an excellent solution for automated or robotic welding cells due to its consistent feedability and arc stability.
