Select 120C

Low Alloy / Metal Cored / Gas Shielded

Resources

Features

  • Formulated without chromium to achieve a high strength with no concern of hexavalent chromium in the welding fume.
  • Pure spray transfer with virtually no spatter
  • Ideal for joining low alloy, high strength steels such as HY-100 and A514.
  • Typical applications of these steels include earthmoving equipment, mining trucks and machinery, and heavy equipment trailers.
  • This electrode may also be used for overlay or surfacing in certain applications.
