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.
WARNING: This product can expose you to chemicals including lead, nickel, and chromium, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.

Thanks for going the extra mile to sell me wire so far I have used a half a roll without any problems rebuilding a brush hog
Put this .030 ER70S-6 through a few small fabrication jobs and it performed consistently. Wire feeds clean without hesitation, and the arc stays steady once dialed in.
The puddle is easy to manage and wets out nicely, which helps keep the bead uniform. It also handles light mill scale and surface contamination better than basic wire.
For everyday mild steel work, it’s a dependable option that just gets the job done.
Very solid ER70S-6 wire. The arc is smooth and stable, and feeding is consistent throughout the spool. The higher deoxidizer content really helps when working on steel that isn’t perfectly clean.
For the price, performance is comparable to more expensive brands. Orders are also processed quickly, which makes the overall experience better. Would definitely purchase again.
