The Hobart Fabco 115 is a premium 3/32-inch flux-cored arc welding (FCAW) wire designed specifically for the fabrication and repair of high-strength, low-alloy steels. Engineered with a basic slag system, this wire is formulated to meet the rigorous demands of welding quenched and tempered steels such as ASTM A514 (T-1), A517, and HY-100. Its AWS classification of E110T5-K4 indicates a tensile strength capability in excess of 110,000 psi, making it an essential consumable for industries requiring maximum structural integrity under heavy loads.
One of the defining characteristics of the Fabco 115 is its basic slag formulation. Unlike rutile-based wires which prioritize operator appeal and smooth bead appearance, basic wires like the Fabco 115 prioritize metallurgical quality. This system provides excellent desulphurization of the weld pool and produces a deposit with superior ductility and impact toughness, even at sub-zero temperatures. Furthermore, the wire is manufactured to produce very low diffusible hydrogen levels, significantly reducing the risk of hydrogen-induced cracking (cold cracking) in the heat-affected zone (HAZ) of high-strength base materials.
This 60lb coil is intended for industrial wire feeders and heavy-duty cycle applications. The 3/32" diameter allows for high deposition rates, improving productivity on thick-section welding in the flat and horizontal positions. While the slag removal requires more effort than rutile wires, the resulting weld quality is unmatched for critical applications involving earthmoving equipment, crane manufacturing, and mining machinery. It operates effectively with both 100% CO2 and Argon/CO2 shielding gas blends, offering flexibility depending on the specific shop requirements and desired arc characteristics.
