MIG WIRE LINCOLN INNERSHIELD NR233 1.6MM 11.34G SPOOL
Lincoln Innershield NR-233 MIG Wire – 1.6mm, 11.34kg Spool
Self-Shielded Flux-Cored Welding Wire (FCAW-S) | AWS E71T-8
Product Overview
The Lincoln Innershield NR-233 is a premium self-shielded flux-cored welding wire designed for structural steel welding without the need for external shielding gas. Available in a 1.6mm (1/16") diameter on an 11.34kg spool, this wire is a strong choice for both training and experienced welders, meeting the mechanical property requirements outlined in AWS D1.8. Whether you're on a construction site, in a fabrication shop, or working out in the field, NR-233 delivers dependable, high-quality welds with minimal setup hassle.
Why Choose Lincoln Innershield NR-233?
Because it's self-shielded, this flux-cored wire eliminates the need for a shielding gas cylinder — making it ideal for outdoor, windy, or hard-to-reach job sites where gas-shielded MIG processes struggle. It runs on DC straight polarity (DCEN) and works well across a range of welding positions.
Key Features
- Enhanced Feedability – An updated wire design boosts wire stiffness, improving feedability and helping produce a smoother arc transfer
- Easy Wire Snap-Off – The wire end breaks off cleanly without tools, making re-strikes quick and hassle-free
- AWS D1.8 Compliant – Meets AWS D1.8 requirements for demand critical welds, with lot testing data available through Lincoln Electric for lot waiver requirements
- Forgiving, User-Friendly Arc – Offers excellent arc control and an accommodating weld puddle, helping operators produce high-quality deposits regardless of skill level
- Minimal Gas Marking – Formulated to reduce gas marking on welds, even after the electrode has been exposed to open air
- Made in the USA – Manufactured from steel made and melted in the USA, complying with Buy America, Buy American, Build America, and American Iron & Steel standards (availability may vary by region)
