1020476 - NS ER70S-6 Copper-Free MIG Wire, 0.035, 1000 lb Reel

High-Volume Efficiency with NS Copper-Free Wire

The NS ER70S-6 .035" Copper-Free MIG Wire represents the gold standard for high-production industrial environments. Packaged on a massive 1000 lb wooden reel, this product is specifically engineered for facilities utilizing robotic cells or hard automation where downtime for spool changes equates to lost revenue. By utilizing a premium copper-free finish, NS (National Standard) eliminates the common issues associated with copper-coated wires, such as copper flaking that clogs liners and gun tips.

This wire meets the AWS ER70S-6 classification, making it a versatile choice for welding mild and carbon steels. The "S-6" designation indicates higher levels of silicon and manganese, which act as deoxidizers to handle light to moderate rust and mill scale on base materials. This chemical composition ensures a fluid weld puddle, excellent wetting action, and a flat bead profile, reducing post-weld grinding requirements.

For Josef Gas customers managing large-scale fabrication floors, the transition to 1000 lb bulk reels offers significant logistical advantages. It reduces the frequency of wire changeovers, minimizes packaging waste, and streamlines inventory management. The copper-free surface also contributes to a cleaner working environment by reducing metal fume emissions related to copper coatings.

Key Industrial Benefits

• Reduced Maintenance: Absence of copper coating prevents flake buildup in conduits and liners.


• Stable Arc: Superior electrical conductivity and consistent wire diameter ensure a stable arc, essential for robotic seam tracking.


• Cost Savings: Bulk packaging lowers the price per pound and reduces labor costs associated with setup time.
