ER70S-6 .030" x 11 lb Spool MIG Welding Wire, Copper Coated Solid Mild Steel GMAW Wire Compatible With Lincoln, Miller, Forney & Harbor Freight Welders, Low Spatter

TWSupply ER70S-6 MIG welding wire is a copper coated solid mild steel wire designed for general purpose GMAW welding applications. Known for smooth arc characteristics, low spatter performance, and reliable feedability, ER70S-6 is widely used in fabrication shops, automotive repair, maintenance, construction, and general metalworking. ER70S-6 contains higher levels of manganese and silicon deoxidizers compared to many standard MIG wires, helping improve weld quality on clean, rusty, scaled, or lightly contaminated steel surfaces. This supports better puddle fluidity, improved wetting action, and consistent weld appearance across a wide range of welding conditions. Designed for all-position welding, TWSupply ER70S-6 performs well on lap welds, butt welds, fillet welds, and general fabrication projects. The copper coating helps improve electrical conductivity, arc stability, smooth wire feeding, and contact tip performance during extended welding sessions. Compatible with many MIG welding machines from Lincoln Electric, Miller, Forney, Harbor Freight, and similar welders using solid wire with shielding gas. ER70S-6 typically performs with CO2 or Argon/CO2 mixed shielding gases, depending on the application and desired weld characteristics. Available in multiple wire diameters and spool sizes for hobby, repair, fabrication, and production welding environments. Manufactured to AWS ER70S-6 classification standards for dependable weld quality and consistent performance.
