The Bohler Ecospark 420 ER70S-6<\/strong> 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<\/strong>, 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.<\/p>\n 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.<\/p>\n Beyond mechanical reliability, the Ecospark 420 offers superior metallurgical performance. It meets AWS A5.18 ER70S-6<\/strong> 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.<\/p>\n 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.<\/p>\n","protected":false},"excerpt":{"rendered":"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.
