ED561137 - Lincoln Innershield NR-211-MP .030 Gasless Flux-Core Wire (2lb Spool)

Lincoln Electric Innershield® NR®-211-MP .030" Flux-Cored Wire

The Lincoln Electric Innershield® NR®-211-MP is a versatile, self-shielded flux-cored wire designed to accommodate a wide range of general-purpose welding applications. Engineered with the professional in mind, this wire (SKU: ED561137) meets AWS E71T-11 classifications and is specifically formulated for use on carbon steels. Its 0.030-inch diameter and convenient 2 lb spool size make it an excellent choice for portable wire feeder units and smaller MIG machines often found in maintenance shops and light fabrication environments.

One of the defining characteristics of the NR-211-MP is its ability to perform in all welding positions—flat, horizontal, vertical, and overhead. This flexibility is crucial for repair work where positioning the workpiece is not always possible. The wire features a fast-freezing slag system, which significantly aids in welding joints with poor fit-up. Furthermore, it is well-regarded for its performance on galvanized or zinc-coated steels, reducing the porosity issues often associated with coated materials.

As a self-shielded wire (FCAW-S), the NR-211-MP requires no external shielding gas, simplifying the equipment setup and making it ideal for outdoor use where wind might disperse a gas shield. It operates on DCEN (Direct Current Electrode Negative) polarity, also known as straight polarity. Operators can expect a smooth arc, moderate spatter, and a bead appearance that is generally superior to many other self-shielded wires in its class. This product is suitable for welding plate thicknesses ranging from 5/16" (7.9 mm) to 1/2" (12.7 mm), depending on the specific application and parameters.
