Carbon Steel / Solid / Gas Shielded


Features

  • A carbon steel, solid “MIG wire” electrode with no copper coating, for gas shielded arc welding.
  • Moderate levels of manganese and silicon compared to 70S-6 electrodes reduces silicate slag on weld deposit which minimizes postweld cleanup.
  • Reduced copper fumes, no copper flaking, crisp arc starts, and a reduction of spatter can all be observed as a result of a bare, copper free wire.
  • Recommended shielding gases are 75-95% argon/balance carbon dioxide, 95-98% argon/balance oxygen, and 100% carbon dioxide.
  • 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.
  • The versatility of a slag free solid wire makes this ideal for general fabrication, structural steel welds, and thin section applications, such as automotive components and hot water heaters with minor amounts of mill scale.
