S279512-029 - Hobart Fabcor Edge Ni1 .045 Metal-Cored Wire 33lb Spool

High-Performance Metal-Cored Wire for Low-Alloy Steels

The Hobart Fabcor Edge Ni1 .045" is a premium metal-cored welding wire designed specifically for the fabrication of nickel-molybdenum steels. Engineered to meet the rigorous demands of heavy industrial applications, this consumable offers a superior alternative to solid wires by providing higher deposition rates and faster travel speeds. The "Edge" series technology ensures a crisp, stable arc with excellent wetting action, allowing for smooth bead profiles and reduced risk of cold lap, even at higher amperages. This particular formulation contains approximately 1% Nickel, which significantly enhances the weld metal's impact toughness, making it an ideal choice for structures subjected to sub-zero temperatures.

Ideally suited for single or multi-pass welding, the Fabcor Edge Ni1 excels in flat and horizontal positions. It is formulated to operate effectively with high-argon gas mixtures, specifically 75% Argon/25% CO2 or 98% Argon/2% Oxygen. This versatility allows fabricators to optimize their shielding gas selection based on available supply or specific arc characteristic preferences. The wire produces minimal spatter and a thin, easily removable slag (often appearing as small islands of silicon), which drastically reduces post-weld cleaning time and labor costs associated with grinding. This efficiency makes it a cost-effective solution for high-volume production environments.

Metallurgically, the Fabcor Edge Ni1 is designed to match the mechanical properties of 80,000 psi tensile strength steels. It is frequently utilized in the welding of 1/2 Ni - 1/4 Mo, 1 Ni - 1/4 Mo, and 1-1/2 Ni - 1/4 Mo steels. Additionally, it serves as a viable option for welding weathering steels in applications where a precise color match is not a critical requirement. The wire's ability to maintain ductility and toughness at temperatures as low as -50°F (-45°C) ensures structural integrity in harsh operating environments, such as arctic mining operations or unheated rail transport.

Packaged in a standard 33lb spool, this product fits most industrial wire feeders. The precision winding ensures consistent feeding performance, reducing downtime caused by tangles or feedability issues. Whether used in automated robotic cells or manual semi-automatic welding, the Hobart Fabcor Edge Ni1 delivers consistent, high-quality results that professional fabricators rely on for critical structural welds.
