87316 - Böhler ECOspark 0.035 Copper-Free MIG Wire 20kg

Smoother Feeding, Less Downtime, Better Welds

If you are tired of your MIG gun sputtering halfway through a job or constantly having to blow out your liner because of copper dust, it is time to switch to Böhler Welding's ECOspark 0.035" Copper-Free MIG Wire. This isn't just standard MIG wire; it's engineered to solve the biggest headache welders face: feedability. Traditional wires are coated in copper to prevent rust and help conductivity, but that copper often flakes off as it travels through the drive rolls and liner. Eventually, that dust clogs up your gun, causing drag, erratic arc starts, and burn-backs. ECOspark eliminates that problem entirely with a specially treated, polished surface that feeds smooth as silk, hour after hour.

Let's talk about the spool size. This comes on a 20kg spool, which is about 44 pounds. That is significantly more wire than the standard 33lb or 15kg spools you might be used to. For a busy shop, that means you aren't stopping to swap out spools nearly as often. You get more arc time and less downtime. The wire itself is a classic ER70S-6, meaning it has the high silicon and manganese content you need to handle steel that isn't perfectly clean. It wets out nicely, digs in for good penetration, and handles mill scale or light rust without porosity issues. Whether you are running short-circuit on thin gauge sheet metal or cranking up the voltage for spray transfer on heavy plate, this wire holds a tight, consistent arc.

Another huge benefit is consumable life. Because the wire is so clean, it doesn't wear out your contact tips as fast as copper-coated wire does. You get better electrical contact for longer periods, which means fewer trips to the tool crib for new tips. Plus, for those of you working in tighter spaces or with less ventilation, you will appreciate that this wire generates fewer fumes. Since there is no copper burning off in the arc, the fume levels are lower, making for a slightly cleaner breathing zone under your hood.

This wire is perfect for anyone doing serious fabrication work—from automotive repairs and roll cages to structural beams and heavy equipment repair. It runs great on standard CV MIG machines and is absolutely killer if you have a wire feeder that is a bit finicky, as the smooth surface reduces drag significantly. Load up a 20kg spool of ECOspark and experience the difference a premium, copper-free wire makes in your daily welding grind.
