Hobart Fabco 73: High-Performance Self-Shielded Wire

The Hobart Fabco 73 is a premium 3/32-inch flux-cored welding wire designed for heavy-duty industrial applications. Classified as an AWS E70T-4 electrode, this wire is engineered to deliver exceptionally high deposition rates, making it a top choice for structural steel fabrication and heavy equipment repair where speed and efficiency are paramount. Supplied in a substantial 60 lb coil, this product ensures long run times with fewer interruptions for spool changes, optimizing workflow in high-volume welding environments.

Technical Superiority and Performance

Fabco 73 operates using the self-shielded flux-cored arc welding (FCAW-S) process, meaning it requires no external shielding gas. This feature makes it ideal for field applications where wind might disturb gas coverage or where hauling gas cylinders is impractical. The wire runs on Direct Current Electrode Positive (DCEP) and produces a globular transfer that provides deep penetration and sound welds. Its chemical composition offers a unique desulfurizing action, which significantly aids in resisting cracking, even when welding on steel with higher sulfur content or minor surface contaminants.

Application Suitability

This wire is specifically formulated for welding in the flat and horizontal positions. It excels in joining carbon steels and is widely used in the fabrication of machinery bases, heavy construction equipment, and structural components. The slag system is designed for easy removal, often peeling off with minimal effort, which reduces post-weld cleanup time. With a typical tensile strength exceeding standard mild steel requirements, the Fabco 73 ensures robust and durable connections for critical infrastructure projects.
