CO2 MIG Welding Wire

CO₂ MIG Welding Wire, commonly known as ER70S-6, is a copper-coated solid wire used in Gas Metal Arc Welding (GMAW) processes. It is specifically designed for welding mild and low alloy steels using CO₂ or mixed shielding gases (CO₂ + Argon). It is widely used in automobile, fabrication, construction, and shipbuilding industries.

Key Features:

  • Excellent Arc Stability : Provides smooth welding performance with minimal spatter.
  • High Deposition Rate : Enhances productivity in continuous welding operations.
  • Good Mechanical Properties : Strong welds with high tensile strength and elongation.
  • Low Spatter & Easy Slag Removal : Reduces cleanup time post-welding.
  • Copper Coated : Improves electrical conductivity and prevents rusting.
