S246529-008 - Hobart Fabco RXR 3/32" E70T-1 Flux-Cored Wire, 600 lb Drum

Technical Performance: Hobart Fabco RXR E70T-1

The Hobart Fabco RXR is a gas-shielded flux-cored wire (FCAW-G) classified as E70T-1, specifically engineered for flat and horizontal welding of carbon steels. With a large 3/32" diameter, this wire is a powerhouse for high-deposition applications where filling joints rapidly is critical. It excels in single and multiple pass applications, providing deep penetration and strong fusion. The wire operates on DCEP (Direct Current Electrode Positive) and is designed exclusively for use with 100% CO2 shielding gas, which promotes a broad, deep penetration profile ideal for thick structural plates.

Welders will appreciate the arc characteristics of the Fabco RXR. It delivers a smooth, stable arc with a fluid puddle that wets out excellently at the toes, minimizing the risk of cold lap and lack of fusion. The slag system is formulated to cover the weld bead completely, protecting it during cooling, yet it detaches easily—often curling up on its own—to reveal a clean, high-quality weld surface. This ease of slag removal is particularly beneficial in multi-pass welding scenarios, reducing the inter-pass cleaning time and the risk of slag inclusions.

The "RXR" designation highlights its enhanced resistance to surface contaminants. The flux core contains elevated levels of silicon and manganese deoxidizers, which actively scavenge oxygen and impurities from the weld pool. This makes the wire exceptionally capable of handling base metals that have not been perfectly cleaned, such as steel with moderate rust or mill scale. Whether you are welding heavy machinery frames, structural beams, or barge components, the Hobart Fabco RXR provides the consistency and mechanical properties required for critical welds, including a minimum tensile strength of 70,000 psi.
