S246519-002 - Hobart Fabco RXR Flux-Cored Wire, 1/16", 60lb Coil

Industrial Grade E70T-1 Flux-Cored Wire

The Hobart Fabco RXR is a premium gas-shielded flux-cored wire engineered for heavy-duty industrial fabrication. Classified as an AWS E70T-1 electrode, this wire is specifically formulated to address common challenges found in structural steel manufacturing, particularly surface contaminants. The "RXR" designation within the Hobart family signifies a robust chemical composition rich in deoxidizers, such as silicon and manganese. These elements actively scavenge oxygen during the welding process, significantly reducing the risk of porosity when welding over mill scale, rust, and other surface impurities common in hot-rolled steel.

Designed for use with 100% CO2 shielding gas, the Fabco RXR delivers a deep penetrating arc that ensures solid root fusion in fillet and groove welds. The wire is optimized for flat and horizontal positions, taking advantage of a fluid puddle system that wets out smoothly at the toes, reducing stress concentrations and improving fatigue life in dynamic structures. This makes it an ideal choice for the manufacturing of railcars, barges, ships, and heavy earth-moving equipment where structural integrity is paramount.

The 1/16-inch diameter offered in this 60lb coil configuration is suited for high-amperage applications where deposition rate is a critical productivity metric. By utilizing a larger diameter wire, fabricators can achieve higher travel speeds and lay down more weld metal per hour compared to smaller diameter solid wires or stick electrodes. The 60lb coil format is designed for industrial wire feeders and boom-mounted systems, minimizing downtime associated with frequent spool changes. This product supports both single and multiple pass welding procedures, providing versatility across varying plate thicknesses found in general construction and heavy fabrication sectors.

Technical specifications indicate that while this wire excels in flat and horizontal fillets, its fluid slag system is not designed for out-of-position welding (vertical up or overhead). However, for shop-floor fabrication where parts can be positioned, the Fabco RXR offers superior efficiency and weld quality. The resulting weld deposit exhibits excellent mechanical properties consistent with mild steel requirements, ensuring code compliance for standard structural applications.
