87318 - Kiswel Ecospark 420 0.045 Copper-Free MIG Wire Drum

Premium Copper-Free MIG Wire for Automation

The Kiswel Ecospark 420 ER70S-6 MIG Wire in the 0.045-inch diameter is a high-performance, copper-free solid wire designed specifically to meet the rigorous demands of robotic and high-speed automated welding. Packaged in a substantial 250kg (551 lb) drum, this product is engineered to maximize arc-on time and minimize the frequency of spool changes, making it an ideal choice for industrial manufacturing environments where efficiency is paramount.

Unlike traditional copper-coated wires, the Ecospark 420 features a unique surface treatment that provides excellent conductivity and rust protection without the use of copper. This innovation solves one of the most persistent issues in continuous welding: copper flaking. Over time, copper flakes from standard wires can accumulate inside gun liners and contact tips, leading to erratic feeding, arc instability, and frequent maintenance stops. By utilizing Ecospark 420, fabricators can significantly extend the lifespan of their torch consumables and maintain a consistent, trouble-free wire feed, even through long conduit runs typical in robotic setups.

Key Performance Benefits

Beyond its feeding reliability, this wire delivers exceptional weld quality. It produces a stable arc with minimal spatter, reducing the need for post-weld grinding and cleanup. The wire chemistry meets AWS A5.18 ER70S-6 standards, ensuring high tensile strength and excellent deoxidizing properties, which allow it to handle light mill scale and surface contaminants effectively. Additionally, the absence of copper coating results in cleaner welding fumes, contributing to a healthier working environment for operators.

Applications

• Robotic Welding Cells: The bulk drum and non-flaking surface are perfect for continuous, automated operations.
• Automotive Manufacturing: Delivers consistent penetration and bead appearance required for chassis and structural components.
• Heavy Fabrication: Suitable for welding structural steel, farm implements, and general machinery.

Invest in the Kiswel Ecospark 420 to streamline your production line. The 250kg drum configuration ensures you spend less time swapping wire and more time welding, while the advanced wire finish guarantees the reliability your automated systems require.
