Select 820-Ni1

Low Alloy / Flux Cored / Gas Shielded


Features

  • Intended for use with 100% CO₂ or blends of 75-80% Ar/balance CO₂ shielding gases.
  • Designed with 1% nickel and microalloying to produce welds with enhanced CVN toughness.
  • The arc transfer is soft; it melts onto the puddle in a small to medium droplet mode.
  • Typically used to weld steels such as ASTM A203, Gr A, and A352, Gr LC1 and LC2.
  • This product is used in offshore platform construction, welding mining machinery, and bridge construction.
