MIG Welding Wire ER70S-6 1.6mm is a copper-coated mild steel wire designed for CO2 or Argon-CO2 mixed gas-shielded arc welding. It offers superior feedability, stable arc performance, minimal spatter, and excellent weld bead formation. Ideal for all-position welding, it provides high tensile strength, crack resistance, and low hydrogen content, making it suitable for heavy-duty applications.
Optimized for 100% CO2 or Argon + CO2 mixed gas welding
Stable arc with minimal spatter for clean welds
High tensile strength (545 MPa) and excellent crack resistance
Thin, easy-to-remove slag for efficient cleanup
Suitable for all-position welding (F, H, OH, V)
