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

Premium Performance for Automated Welding

Upgrade your welding operations with the NS ER70S-6 .035" Copper-Free MIG Wire, delivered on a substantial 1000 lb wooden reel. This wire is designed for the professional welder and fabricator who demands consistency, feedability, and superior arc characteristics. The "Copper-Free" (CF) technology is a game-changer for long-conduit runs and push-pull systems often found in automated setups. Without the layer of copper found on traditional wires, you eliminate the risk of copper shavings accumulating in your liner, which is a leading cause of erratic feeding and arc instability.

The ER70S-6 formulation provides the highest combination of manganese and silicon deoxidizers available in a standard mild steel MIG wire. This allows for higher welding currents with CO2 shielding gas and improved puddle fluidity with Argon/CO2 mixtures. The result is a smooth, spatter-free weld deposit that ties in nicely at the toes, even when welding on hot-rolled steel with scale or minor surface contaminants.

This 1000 lb reel format is intended for use with heavy-duty payoff equipment or dereelers. It is the ideal solution for shops running continuous shifts where stopping to change a 33lb or 44lb spool interrupts the workflow. Whether you are welding automotive components, structural steel, or heavy machinery, this NS wire delivers the reliability required for critical welds.

Technical Advantages

• Superior Feedability: Precision winding and consistent cast/helix ensure the wire feeds smoothly without wandering.
• Extended Consumable Life: Cleaner wire surface reduces wear on contact tips and liners.
• Versatile Shielding Gas: Performs exceptionally well with 100% CO2 or 75/25 Argon/CO2 mixes.
