Upgrade your welding setup with the Bohler Eco-Spark 420 MIG Wire, a top-tier .045" (1.2mm) solid wire that leaves the copper coating behind. If you are tired of dealing with bird-nesting, erratic feeding, or constantly changing contact tips due to copper buildup, this is the solution. The Eco-Spark 420 uses advanced surface technology to provide a bare, copper-free wire that feeds smoothly and strikes consistently, giving you a buttery-smooth arc every time you pull the trigger.
This 20kg (44lb) spool is perfect for welders who want to keep the arc on longer without frequent spool changes. The ER70S-6 classification ensures it handles surface contaminants like rust and mill scale well, thanks to its high manganese and silicon content. Whether you are working on automotive repairs, general steel fabrication, or heavy structural projects, this wire delivers deep penetration and excellent wetting characteristics.
Why Choose Copper-Free?
Compatible with standard MIG welders capable of running .045" wire, the Eco-Spark 420 is the modern standard for professional welders who demand reliability and performance. Make the switch to copper-free and experience the difference in your daily welding operations.
