Carbon Steel / Flux Cored / Gas Shielded

Resources

Features

  • Arc transfers in a small droplet spray, with improved stability at lower currents.
  • The slag is typically self-peeling and removes very cleanly.
  • Intended for steels such as ASTM A36, A285, A515-Grade 70, and A516-Grade 70.
  • Well suited for structural welding, general fabrication, welding rail cars and construction machinery, and welding earthmoving machinery.
