S246525-002 - Hobart Fabco RXR 5/64" E70T-1 Flux-Cored Wire 60lb Coil

Industrial-Grade E70T-1 Flux-Cored Wire for Heavy Fabrication

The Hobart Fabco RXR is a premium gas-shielded flux-cored wire engineered to meet the rigorous demands of heavy industrial manufacturing and structural fabrication. Classified as an AWS E70T-1 electrode, this wire is specifically formulated to provide high deposition rates in the flat and horizontal positions. It is an ideal choice for fabrication shops and manufacturing plants where efficiency and weld quality are paramount. The 5/64-inch diameter offers substantial current carrying capacity, allowing for deep penetration and rapid travel speeds on thick plate sections.

One of the defining technical characteristics of the Fabco RXR is its enhanced deoxidization package. The flux core contains elevated levels of silicon and manganese, which react chemically with contaminants in the weld pool. This feature makes the wire exceptionally tolerant of mill scale, rust, and other surface impurities commonly found on hot-rolled structural steel. For industrial operations, this translates to reduced pre-weld preparation time, as the wire can produce sound, porosity-free welds even on less-than-pristine surfaces. This capability is particularly beneficial in railcar manufacturing, shipbuilding, and heavy equipment production where extensive grinding of every joint is not feasible.

The wire is designed for use with 100% CO2 shielding gas. Utilizing CO2 not only reduces consumable costs compared to argon blends but also contributes to the deep penetration profile required for heavy fillet and groove welds. The slag system of the Fabco RXR is formulated to support the weld puddle effectively while cooling, resulting in a flat to slightly convex bead contour that blends smoothly with the base metal. Post-weld, the slag is easily detachable, often lifting by itself, which minimizes downtime associated with chipping and grinding between passes or before painting.

Supplied in a 60lb coil, this product is intended for industrial wire feeders equipped with appropriate coil adapters. The packaging ensures a long run time between changeovers, further supporting high-productivity environments. The mechanical properties of the deposited weld metal meet or exceed AWS requirements for tensile strength and yield strength, ensuring structural integrity in critical applications.
