The Hobart Fabco 101K3 is a premium gas-shielded flux-cored wire designed specifically for the welding of high-strength, low-alloy steels. Engineered to meet the rigorous demands of heavy industrial fabrication, this wire carries the AWS classification E101T1-K3. It is formulated to provide exceptional mechanical properties, including tensile strengths exceeding 100,000 psi, making it an ideal choice for structural components that require superior load-bearing capabilities. The 1/16-inch diameter offers a balance of deposition rate and puddle control, suitable for medium-to-heavy plate thicknesses often found in shipbuilding, heavy equipment manufacturing, and offshore construction.
One of the defining characteristics of the Fabco 101K3 is its optimization for use with 100% CO2 shielding gas. This feature allows fabricators to achieve high-quality welds with excellent penetration profile while maintaining operational economy compared to mixed gas solutions. Despite using CO2, the wire delivers a stable arc and a fast-freezing slag system, which supports all-position welding. This versatility ensures that operators can tackle vertical and overhead joints with confidence, maintaining bead consistency and reducing the need for complex part positioning.
Packaged in a substantial 60lb coil, this product is geared towards high-volume production environments where downtime for spool changes must be minimized. The wire's chemical composition is tightly controlled to ensure low hydrogen levels in the weld deposit, significantly reducing the risk of hydrogen-induced cracking—a critical factor when welding quenched and tempered steels like HY-80 and A514. Whether used for single-pass fillets or multi-pass groove welds, the Hobart Fabco 101K3 delivers the reliability and performance required for safety-critical infrastructure.
