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

Smooth Feeding, Clean Welds, No Clogs

If you run a robotic cell or a heavy-duty turntable setup, you know that downtime is the enemy. The Bohler Ecospark 420 is the solution to the constant headache of liner maintenance and contact tip failure caused by copper flaking. This 0.035" ER70S-6 MIG wire is completely copper-free, meaning there is no soft metal coating to shave off inside your gun liner or conduit. The result? A wire that glides smoothly hour after hour, shift after shift.

Welders and operators will immediately notice the stability of the arc. Ecospark 420 is engineered to ignite instantly and maintain a focused, consistent arc even at high wire feed speeds. The spatter control is exceptional, leaving your parts cleaner and reducing the need for chipping or grinding after the weld is laid. Because it is an ER70S-6 class wire, it contains high levels of deoxidizers (manganese and silicon), which help it handle minor surface contaminants on mill scale or mild steel, ensuring sound, porosity-free welds.

The 250kg drum is a beast of a package, designed to keep your machine running longer without interruption. No more stopping every few hours to swap out a small spool. This bulk pack is perfect for high-volume jobs where consistency is key. Additionally, the lack of copper coating means you aren't breathing in copper fumes, making for a slightly safer and cleaner shop environment. Whether you are welding automotive frames, structural components, or general manufacturing parts, Ecospark 420 delivers the reliability you need to keep the green light on.

Switching to copper-free wire doesn't mean sacrificing shelf life. Bohler's advanced surface treatment protects the wire from rust and corrosion just as well as copper, but without the mess. Upgrade your feed system today with Ecospark 420 and experience the difference that a truly clean wire makes.
