S248239-002 - Hobart FabCO 73 7/64" Flux-Cored Wire, 60 lb Coil

Hobart FabCO 73: High-Performance Flux-Cored Wire for Industrial Fabrication

The Hobart FabCO 73 is a premium gas-shielded flux-cored wire engineered for heavy-duty industrial applications where surface preparation may be less than ideal. With a diameter of 7/64 inches and packaged in a substantial 60 lb coil, this wire is formulated to tackle the rigorous demands of structural steel fabrication, heavy equipment manufacturing, and shipbuilding. Its chemical composition is rich in de-oxidizing elements, allowing it to penetrate and fuse effectively even when welding over moderate levels of mill scale, rust, and other surface contaminants that would typically compromise weld integrity.

Designed exclusively for single-pass applications, the FabCO 73 excels in depositing high volumes of weld metal quickly and efficiently. It operates using 100% CO2 shielding gas, which not only provides deep penetration but also offers a cost-effective gas solution for large-scale operations. The wire is classified under AWS E70T-1 specifications, ensuring it meets strict industry standards for mechanical properties and weld quality. Users can expect a stable arc and a fluid puddle that wets out smoothly, resulting in a flat, aesthetically pleasing bead profile with minimal effort.

This wire is specifically optimized for flat and horizontal welding positions, making it a staple for fillet welds on heavy plate sections. Whether fabricating machine bases, railcars, or construction beams, the FabCO 73 delivers the reliability and speed required to maintain high throughput in production environments. Its ability to handle dirty steel without sacrificing bead appearance makes it an invaluable asset for workshops that process hot-rolled steel or outdoor weathering materials.
