S280212-029 - Hobart FabCOR 1100 .045 Metal Core Wire 33lb Spool

High-Performance Metal Core Wire for Critical Applications

The Hobart FabCOR® 1100 is a premium gas-shielded metal core tubular wire designed to meet the rigorous demands of welding high-strength, low-alloy steels. Engineered with a specific formulation to achieve a minimum tensile strength of 110,000 psi, this wire is the ideal choice for fabricating components using ASTM 514, HY-100, and T1 steels. Its AWS classification of E110C-K4 H4 (and metric E76C-K4-H4) underscores its capability to deliver robust mechanical properties while maintaining low diffusible hydrogen levels (H4), which is critical for preventing hydrogen-induced cracking in sensitive high-strength materials.

One of the defining technical advantages of the FabCOR 1100 is its metal core construction. Unlike solid wires, the tubular design filled with metallic powders allows for higher current densities, resulting in significantly higher deposition rates. This efficiency is achieved even at lower heat inputs, which helps preserve the heat-affected zone (HAZ) properties of quenched and tempered steels. The wire is formulated to provide excellent chemical consistency across the weld deposit, ensuring that mechanical requirements for yield strength and impact toughness are reliably met in both single and multi-pass applications.

In addition to its mechanical prowess, the FabCOR 1100 addresses environmental and operational concerns within the industrial workspace. The chemical composition is balanced to minimize particulate generation, resulting in lower smoke and fume levels compared to conventional flux-cored or metal-cored wires of similar strength classes. This feature aids in maintaining cleaner shop air quality and improving visibility for the operator and automated systems. Packaged in a standard 33 lb spool with a .045" diameter, this wire integrates seamlessly into existing MIG welding setups requiring high-performance consumables for heavy-duty fabrication.
