Select 70C-LMn

Carbon Steel / Metal Cored / Gas Shielded


Features

  • Designed for single or multiple pass welding on steels requiring a minimum of 70,000 psi tensile strength.
  • Designed to produce cleaner weld deposits than conventional metal cored electrodes, thus allowing for minimal slag islands and the ability to deposit multiple beads without cleaup between passes.
  • Arc transfer is a stable, fine droplet spray.
  • Total manganese (Mn) content is significantly reduced compared to standard E70C-6 or E70S-6 AWS classed electrodes.
  • Ideal for welding structural steel, thin plate fabrication, general fabrication, and welding of thin-walled tanks applications where ASTM A36, A285, A515-Gr 70, and A516-Gr 70 type materials are being used.
