ED030933 - Lincoln Innershield NR-233 1/16" Flux-Cored Wire - 12.5 lb Spool

Premium Structural Welding Wire for Heavy Fabrication

The Lincoln Electric Innershield® NR-233 is a versatile, self-shielded, flux-cored wire designed to meet the rigorous demands of the structural steel industry. Engineered for high-speed welding on mild steel, this 1/16-inch diameter wire offers exceptional performance in all positions, making it a go-to choice for on-site erection and shop fabrication alike. As a self-shielded wire (FCAW-S), the NR-233 eliminates the need for external shielding gas, significantly simplifying equipment setup and improving portability in field applications where wind might otherwise disrupt gas coverage.

This specific spool size of 12.5 lbs is ideal for portable wire feeders and smaller jobs where handling large drums or 33lb spools is impractical. Despite its compact packaging, it delivers the same industrial-grade performance Lincoln Electric is known for. The wire is formulated to produce a smooth arc with low spatter levels, ensuring operator comfort and high-quality weld deposits. Its quick-freezing slag system supports out-of-position welding, including vertical-up and overhead, without sacrificing bead contour or penetration.

One of the standout features of the NR-233 is its compliance with AWS E71T-8 specifications, making it suitable for seismic structural steel erection where ductility and toughness are critical. It provides deep penetration and excellent fusion, reducing the risk of lack-of-fusion defects common in heavy plate welding. The wire is designed to operate on DCEN (Direct Current Electrode Negative) polarity, which contributes to its smooth running characteristics and efficient metal transfer.

At Josef Gas, we understand that reliability is paramount in industrial welding. The Lincoln NR-233 is manufactured to strict quality standards, ensuring consistent diameter, cast, and helix for trouble-free feeding through long gun cables. Whether you are welding column splices, beam-to-column connections, or general heavy equipment repair, this wire provides the mechanical properties and usability required to get the job done right. Please note that this product is often sold in master cartons; check the packaging details to ensure you order the correct quantity for your project needs.
