Welders Supply is proud to offer the Hobart Fabco 115K3, a 3/32" diameter flux-cored wire supplied in a 60lb coil for heavy-duty industrial applications. This wire is formulated for the welding of high-strength low-alloy (HSLA) and quenched and tempered steels, delivering weld metal that matches the mechanical properties of premium base materials like HY-100, A514, and A517. If your shop handles heavy equipment repair, structural steel fabrication, or mining machinery, the Fabco 115K3 provides the reliability and strength required for critical joints.
The Fabco 115K3 utilizes a basic slag system, which is the gold standard for crack resistance in flux-cored welding. This formulation ensures that the weld metal has very low levels of impurities and diffusible hydrogen, providing maximum resistance to cold cracking and centerline cracking. This is particularly important when welding thick sections or highly restrained joints common in heavy manufacturing. The wire produces X-ray quality welds with excellent Charpy V-Notch impact values, ensuring ductility and toughness even in sub-zero service temperatures.
Designed for flat and horizontal welding positions, this wire offers high deposition rates that can significantly improve productivity on large weldments. It runs smoothly with 100% CO2 for deep penetration and economy, or with a 75/25 Argon/CO2 mix for a smoother arc and reduced spatter. The 3/32" diameter is ideal for filling large grooves efficiently. When you need a wire that stands up to extreme stress and load-bearing requirements, the Hobart Fabco 115K3 is the professional's choice for high-yield strength steel fabrication.
