S246512-029 - Hobart Fabco RXR .045 Flux-Cored Wire 33lb Spool

Technical Overview of Hobart Fabco RXR

The Hobart Fabco RXR is a premium gas-shielded flux-cored wire formulated to meet the AWS E70T-1 classification. This wire is specifically engineered for the welding of mild and medium carbon steels in the flat and horizontal positions. Its chemical composition is enriched with a higher level of de-oxidizing elements, including manganese and silicon, which significantly enhances its ability to weld over contaminants such as heavy mill scale and rust without compromising the integrity of the weld deposit. This makes it an ideal choice for structural fabrication environments where rigorous surface preparation may not always be feasible.

Designed for use with 100% CO2 shielding gas, the Fabco RXR delivers a spray-type transfer that results in deep penetration and excellent sidewall fusion. The slag system is designed to be easily detachable, often curling up on its own, which reduces inter-pass cleaning time in multi-pass applications. The 0.045-inch diameter offers a versatile operating range, allowing for high deposition rates that can significantly improve throughput in heavy manufacturing sectors such as railcar construction, shipbuilding, and heavy earth-moving equipment fabrication.

Mechanically, the deposited weld metal exhibits consistent tensile and yield strengths suitable for general purpose structural applications. The wire is packaged in a 33lb spool, ensuring compatibility with standard industrial wire feeders. By utilizing Direct Current Electrode Positive (DCEP) polarity, operators can achieve a stable arc with minimal spatter, ensuring high-quality weldments even under less-than-ideal base metal conditions.
