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

Premium Copper-Free Welding Wire for High-Performance Fabrication

The Böhler Welding ECOspark 0.035" (0.9mm) Copper-Free MIG Wire is a high-efficiency, non-copper coated solid wire designed for the Gas Metal Arc Welding (GMAW) of unalloyed and low-alloyed steels. Engineered by voestalpine Böhler Welding, this product represents a significant advancement in wire surface technology. Unlike traditional copper-coated wires, the ECOspark series utilizes a special surface treatment that ensures superior feedability and arc stability without the reliance on a copper layer. This makes it an exceptional choice for both semi-automatic and fully robotic welding applications where wire feeding reliability is critical to production throughput.

One of the defining technical characteristics of this wire is its classification as an ER70S-6 (G4Si1) electrode. It contains high levels of manganese and silicon, which act as effective deoxidizers, allowing the wire to perform well even on base metals with minor rust or mill scale. However, the standout feature remains its copper-free finish. By eliminating the copper coating, Böhler has removed the risk of copper flaking—a common issue where microscopic particles of copper detach from the wire and accumulate inside the wire liner or contact tip. This accumulation often leads to micro-arcing, unstable wire feeding, and premature failure of torch consumables. With ECOspark, the wire surface is extremely clean and smooth, promoting consistent electrical conductivity and reducing the frequency of liner cleanouts and tip replacements.

The 20kg (approximately 44 lbs) spool size is specifically optimized for industrial environments. Standard spools often come in 15kg or 33lb weights; the increased capacity of the 20kg unit allows for longer continuous welding durations, reducing the downtime associated with spool changeovers. This is particularly advantageous in high-volume manufacturing sectors such as automotive, structural steel, and heavy machinery fabrication. Furthermore, the absence of copper coating contributes to a healthier working environment by significantly lowering the emission of copper fumes during the welding process, aligning with modern occupational safety standards.

In terms of arc physics, ECOspark delivers a stable, spatter-free arc across a wide range of parameters. It excels in both short-circuit and spray transfer modes, providing excellent wetting characteristics and a flat bead profile. The wire is designed to operate with mixed shielding gases (Argon/CO2) for optimal performance, though it is also compatible with 100% CO2. For industrial procurement specialists seeking a reliable, high-performance consumable that reduces maintenance overhead and improves process stability, the Böhler ECOspark 87316 is a superior solution.
