S281212-050 - Hobart FabCOR 80D2 0.045 Metal-Cored Wire 500lb X-Pak

Technical Overview of Hobart FabCOR 80D2

The Hobart FabCOR 80D2 is a premium metal-cored arc welding (MCAW) wire designed to meet the rigorous demands of high-strength, low-alloy (HSLA) steel fabrication. Classified under AWS A5.28 as E80C-Ni1, this wire is formulated with a nominal 1% Nickel content, providing enhanced mechanical properties, particularly tensile strength and impact toughness at lower temperatures. The .045-inch diameter wire is supplied in a high-volume 500 lb Exacto Pak (X-Pak), making it an ideal choice for automated robotic cells or continuous manual welding operations where downtime for spool changes must be minimized.

Metallurgically, the FabCOR 80D2 is engineered to operate optimally with a shielding gas mixture of 98% Argon and 2% Oxygen. This specific gas composition promotes a stable spray transfer mode with very low spatter generation and high deposition efficiency (typically exceeding 95%). The metal-cored construction allows for higher current densities than solid wires of equivalent diameter, resulting in faster travel speeds and deeper penetration profiles. This makes the wire particularly effective for single and multi-pass welding of steels with tensile strengths in the 80,000 psi range.

The wire is characterized by its excellent gap-bridging capabilities compared to solid wire, although it is primarily designed for flat and horizontal fillet welds. The chemical composition is tightly controlled to ensure consistent weld metal properties, meeting the requirements for critical structural components in heavy machinery and mining equipment. Storage and handling should follow standard low-hydrogen practices to maintain the integrity of the wire surface and fill.
