Select ER70S-6NC

Carbon Steel / Solid / Gas Shielded

Resources

Features

  • A copper free carbon steel, solid “MIG wire” electrode, for gas shielded arc welding.
  • Higher level of deoxidizers enhances welding over hot rolled and rusted/oxidized plate material.
  • Copper free technology results in reduced copper fumes, no copper flaking, crisp arc starts, and a reduction of spatter.
  • Intended for welding carbon steels, such as ASTM A36, A515, A516, and A572.
  • Smaller diameters (1/16” or smaller) can be pulse welded in all positions.
