Select 812-K2C

Low Alloy / Flux Cored / Gas Shielded

Resources

Features

  • 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
  • Designed for use with 100% CO₂ shielding gas with excellent CVN toughness values down to -76º F
  • The arc transfer mode is a smooth, ball transfer, that produces minimal spatter.
  • Typical applications include low temperature storage tanks, offshore drilling rigs, shipbuilding, and construction machinery.
