Select 70C-6LS

Carbon Steel / Metal Cored / Gas Shielded


Features

  • Designed to produce cleaner weld deposits, with minimal slag islands, than conventional metal cored electrodes
  • Minimizing slag islands and spatter requires less cleanup when multiple beads are to be deposited.
  • Arc transfer is a stable, fine droplet spray
  • Ideal for welding structural steel, thin plate fabrication, general fabrication, and welding of thin walled tanks.
  • Intended for welding carbon steels such as ASTM A36, A285, A515-Gr 70, A516-Gr 70 and A572
