Copper Bridge ER70S-6 is a copper-coated solid MIG wire for mild steel, built for smooth feeding and strong welds. With higher manganese and silicon deoxidizers, it helps produce clean, low-porosity welds even when steel isn’t perfectly clean. Use it with CO₂ or Ar/CO₂ mix gas for automotive work, fabrication, repairs, and shop welding. Great value vs big-box wire without sacrificing performance.
