Select 91-K2

Low Alloy / Flux Cored / Gas Shielded

Resources

Features

  • Intended for use with 100% CO₂ shielding gas with a stable, small to medium droplet arc transfer that produces low spatter.
  • Slag removes easily with no residual slag, and the bead is finely rippled with good geometry.
  • Intended for single and multiple pass welding of structural steel and fabrications utilizing high strength, low alloy steels, such as HY-80, ASTM A514, A633, and A710.
  • Typical applications include low temperature storage tanks, offshore drilling rigs, shipbuilding, and construction machinery.
