Carbon Steel / Flux Cored / Gas Shielded

Resources

Features

  • This product is optimized for superb arc transfer characteristics with 75-80% Ar/Balance CO₂ shielding gas, but may also be used with 100% CO₂, with the transfer mode being small droplets and resembling molten metal spraying onto the weld puddle.
  • All-position weldability, with minimal spatter and excellent bead geometry.
  • Mechanical properties are excellent with either gas, CVN impact values are particularly good at temperatures as low as -20°F.
  • Well suited for structural steel welding, shipbuilding, barge construction, and general plate fabrication.
