Select 70C-3

Carbon Steel / Metal Cored / Gas Shielded

Resources

Features

  • Manganese and silicon content are lower than the 70C-6M product, providing lower tensile strength
  • Arc transfer is a small droplet, smooth spray
  • Can be used to weld on hot rolled, oxidized steel with virtually no lack of fusion
  • Minimal slag islands on finished weld deposits

Shielding

  • 75-80% Ar / Balance CO₂
  • 95%Ar / 5% CO₂
