MIG WIRE LINCOLN NR211-MP 1.2MM 11.34KG
Product Overview
The Lincoln Electric Innershield NR-211-MP is a premium self-shielded flux-cored welding wire (FCAW-S), engineered for welders who need reliable, gas-free performance without compromising on weld quality. Supplied in a 1.2mm (0.045") diameter on an 11.34kg (25 lb) spool, this wire is a go-to choice for fabricators, contractors, and DIY welders working on light-gauge to medium-thickness steel — indoors or outdoors.
Because NR-211-MP requires no external shielding gas, it's ideal for job sites, outdoor construction, and windy conditions where gas-shielded MIG wires struggle to maintain arc stability. It delivers smooth arc characteristics, low spatter, easy slag removal, and excellent bead appearance right out of the box.
Key Features & Benefits
- Self-Shielded (Gasless) Flux-Cored Wire – No shielding gas cylinder or regulator needed, saving on equipment costs and setup time
- AWS Classification E71T-11 – Meets AWS A5.20 standards for consistent, code-quality welds
- All-Position Welding – Suitable for flat, horizontal, vertical, and overhead welding applications
- Wide Plate Thickness Range – Recommended for plate thicknesses from 7.9mm (5/16") up to 12.7mm (1/2")
- Excellent for Galvanized & Zinc-Coated Steel – Handles coated materials with minimal porosity
- Fast-Freezing Slag – Accommodates poor fit-up and gaps common in field welding
- Low Spatter, Easy Slag Removal – Reduces post-weld cleanup time
- High Operator Appeal – Smooth, stable arc for consistent bead appearance
- Large 11.34kg (25 lb) Spool – Fewer spool changes, less downtime, ideal for production and heavy-duty projects
