MATRIX CO2 WIRE ER70S-6

The CO₂ Welding Wire ER70S-6 is a premium-grade solid MIG wire designed for high-speed welding of mild and carbon steel using 100% CO₂ or mixed shielding gases. This copper-coated wire provides excellent arc stability, low spatter levels, and smooth bead appearance, making it ideal for both manual and automated MIG welding applications. Engineered with higher levels of manganese and silicon, ER70S-6 delivers strong welds even on slightly rusted or oily surfaces, ensuring consistent performance in structural fabrication, automotive repair, machinery manufacturing, and general metalwork. Available in various diameters (e.g., 0.8mm, 1.0mm and 1.2mm), this wire is perfect for professional welders seeking reliable results across a wide range of welding conditions.
