Select 727

Carbon Steel / Flux Cored / Gas Shielded


Features

  • Intended for single and multiple pass welding of carbon steels, such as ASTM A36, A285, A515-Gr 70, A572-Gr 50, A992-Gr 50, and A516-Gr 70.
  • The arc is a small to medium droplet size spray, with a slightly soft transfer.
  • Well suited for general fabrication and structural steel welding.
  • Typical applications include shipbuilding, mining machinery, agricultural equipment, and earthmoving machinery.
