S278308-29 - Hobart FabCOR F6 Metal-Cored Wire .035 33lb Spool E70C-GS

Technical Overview: Hobart FabCOR F6 Metal-Cored Wire

The Hobart FabCOR F6 is a specialized metal-cored welding wire classified under AWS E70C-GS, designed to address the specific challenges of welding galvanized and thin-gauge steels. Unlike standard metal-cored wires that typically operate on DCEP (Reverse Polarity), the FabCOR F6 is engineered for use with DCEN (Straight Polarity). This polarity configuration directs more heat into the electrode rather than the base material, significantly reducing the risk of burn-through on thin substrates while maintaining the high deposition rates characteristic of metal-cored consumables.

This wire features a composite metal core containing a precise blend of stabilizing elements and deoxidizers. The formulation promotes excellent wetting action and gap-bridging capabilities, making it ideal for applications where fit-up may be inconsistent. The E70C-GS classification indicates a tensile strength of at least 70,000 psi, a composite core, and suitability for single-pass applications. It is optimized for use with Argon/CO2 shielding gas mixtures (typically 75-95% Argon), which helps produce a stable arc with minimal spatter.

Industrial applications for the FabCOR F6 are concentrated in the automotive and light fabrication sectors, particularly where galvanized or zinc-coated steels are prevalent. The wire's chemistry helps mitigate the porosity often associated with welding over zinc coatings, ensuring sound weld deposits with good impact toughness and ductility. The 33lb spool size fits standard industrial wire feeders, providing a balance between portability and run-time efficiency.
