87319 - Bohler Ecospark 420 0.035 Copper-Free MIG Wire Drum

High-Performance Copper-Free MIG Wire for Automation

The Bohler Ecospark 420 ER70S-6 is a premium, non-coppered solid wire designed specifically to meet the rigorous demands of robotic and high-duty cycle automated welding. Supplied in a substantial 250kg drum, this product is engineered to maximize arc time and minimize changeover frequency in industrial manufacturing environments. By eliminating the traditional copper coating, Bohler has removed a common source of feeding issues: copper flaking.

In high-volume production, copper shavings from standard wires can accumulate in liners and contact tips, leading to arc instability, burn-backs, and unscheduled maintenance. The Ecospark 420 features a proprietary surface treatment that ensures excellent conductivity and corrosion resistance without the copper layer. This results in a wire that feeds smoothly over long distances and through complex conduit configurations, making it the ideal choice for large-scale fabrication and automotive assembly lines.

Beyond mechanical reliability, the Ecospark 420 offers superior metallurgical performance. It meets AWS A5.18 ER70S-6 classifications, providing high tensile strength and excellent impact toughness. The wire chemistry is optimized for use with both mixed gases (Argon/CO2) and 100% CO2, delivering a stable arc with extremely low spatter levels. This reduction in spatter translates to less post-weld cleanup and a better surface finish on the final part. Furthermore, the absence of copper coating contributes to a healthier working environment by reducing the formation of copper-bearing welding fumes.

This 0.035" (0.9mm) diameter wire is versatile enough for thin to medium gauge steel applications. The 250kg drum packaging is designed for seamless integration with wire payoff systems, ensuring tangle-free delivery at high feed speeds. For facility managers and welding engineers looking to optimize their production efficiency and part quality, the Bohler Ecospark 420 represents a significant upgrade in consumable technology.
