S292812-053 - Hobart Fabco 712C .045 Flux-Cored Wire 33lb Spool

Technical Overview of Hobart Fabco 712C

The Hobart Fabco 712C is a premium gas-shielded flux-cored wire designed to meet the rigorous demands of heavy industrial fabrication. Engineered with a specific formulation to perform optimally with 100% CO2 shielding gas, this wire delivers exceptional mechanical properties, particularly in low-temperature environments. It meets AWS classifications E71T-1C, E71T-9C, and E71T-12C H8, indicating its suitability for critical applications where impact toughness and crack resistance are paramount. The wire is supplied in a 33 lb vacuum-packed spool (Vpsp), ensuring that the low-hydrogen characteristics are preserved during storage and transport, minimizing the risk of hydrogen-induced cracking in the final weldment.

Metallurgically, the Fabco 712C provides a fast-freezing slag system that supports all-position welding, including vertical-up and overhead, without sacrificing bead contour or wetting action. The flux composition is balanced to produce a stable arc with low spatter levels, reducing post-weld cleaning time. Its ability to maintain high impact values (Charpy V-Notch) at sub-zero temperatures makes it a preferred choice for industries operating in harsh climates or requiring code-compliant welds for dynamic loading. The 0.045-inch diameter offers a versatile current range, allowing for both high deposition rates in flat positions and controllable puddles in out-of-position work.

This consumable is particularly effective for single and multiple pass applications on carbon steels. The slag system is designed to be easily removable, often peeling away to reveal a smooth, ripple-free bead profile. By utilizing straight CO2, operators can reduce shielding gas costs while maintaining deep penetration and excellent sidewall fusion. The Fabco 712C represents a convergence of economy and high-performance engineering, tailored for the structural, shipbuilding, and heavy machinery sectors.
