ED561138 - Lincoln Innershield NR-211-MP .035 Gasless Flux Core Wire (2lb Spool)

Lincoln Electric Innershield® NR-211-MP .035" Flux-Cored Wire

The Lincoln Electric Innershield® NR-211-MP (ED561138) is a premium self-shielded flux-cored wire designed to provide versatility and reliability in general fabrication and maintenance applications. Engineered as a Multi-Pass (MP) consumable, this wire distinguishes itself from standard single-pass flux-cored wires by maintaining mechanical integrity even when layering welds on thicker materials, up to 1/2 inch (12.7 mm). This specific spool contains 2 pounds of 0.035-inch diameter wire, making it an excellent choice for portable wire feeders and spool guns often used in field repairs.

Conforming to AWS E71T-11 specifications, the NR-211-MP operates on DCEN (Direct Current Electrode Negative) polarity. It features a fast-freezing slag system that supports all-position welding, including vertical-up and overhead, which is critical for fixed-position repair work. The wire's chemical composition is optimized to handle mild steel and is particularly forgiving on materials with moderate surface contaminants such as rust, oil, or mill scale. Furthermore, it performs exceptionally well on galvanized or zinc-coated steels, reducing the porosity often associated with welding coated materials.

One of the key technical benefits of this product is its independence from external shielding gas. By generating its own protective atmosphere from the flux core, it eliminates the logistical burden of transporting high-pressure gas cylinders. This characteristic makes it the preferred choice for outdoor construction sites, agricultural repairs, and windy environments where traditional MIG (GMAW) gas shielding would be blown away, leading to weld defects. The 2lb spool size is compatible with most standard 4-inch spool hubs found on compact MIG welding machines.
