Select ER70S-3NC

Carbon Steel / Solid / Gas Shielded


Features

  • A copper free carbon steel, solid “MIG wire” electrode, for gas shielded arc welding.
  • Moderate levels of manganese and silicon reduces silicate slag on weld deposit which minimizes postweld cleanup.
  • 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.
