SA 71T-9

Carbon Steel / Flux Cored / Gas Shielded


Features

  • Intended for welding carbon steel plate, such as ASTM A36, A285, A515-Gr70, and A516-Gr70.
  • The arc transfer is smooth and stable in both 100% CO₂ and 75-80% Ar/Balance CO₂.
  • Slag removal and bead geometry are competitive with any of the all position wires sold commercially.
  • Typical applications are welding of railcars, bridge structures, steel structures, and general fabrication.
