DETAILS

UltraCore® 360™ C71 has a seamless design that protects the flux core from environmental exposure helping to maintain low diffusible hydrogen and extend shelf life.

Features

  • Seamless design protects the flux core from environmental exposure helping to maintain low diffusible hydrogen and extend shelf life
  • Copper coating offers superior feedability and extended contact tip life
  • Low spatter and fume levels for less post-weld clean up and a better work environment
  • Low H4 diffusible hydrogen levels minimize the risk of hydrogen induced cracking
  • Premium arc performance and bead appearance

Typical Applications

  • Offshore
  • Shipbuilding
  • Structural
  • Oil & Gas

Welding Positions

  • All

Shielding Gas

  • 100% CO2|Flow rate: 28-38 CFH
