Sifmig Zero SG3 Copper Free Steel MIG Wire – x 0.8 mm x 15 Kg

  • Free from Copper Coating
  • EN ISO 14341-A – G 42 2 C1 / 46 5 M21 4Si1
  • AWS A5.18: ER70S-6

Double-deoxidised mild steel MIG wire, free from copper coating with increased silicon and manganese content for welding unalloyed and low-alloyed mild and medium tensile steels requiring good impact toughness down to -20°C.

Manufactured with a high-quality un-coppered finish for improved feeding and conductivity, SIFMIG ZERO SG3 typically provides a higher ultimate tensile strength over standard SIFMIG SG2 and the absence of copper on the wire surface results in a cleaner deposit and avoids the metallurgical risks of increased copper in the weld pool.

The arc-stability characteristics and improved feedability of the SIFMIG ZERO SG3 make it ideal for robotic or automated processes, where welding steadiness and uniformity are essential in order to avoid welding defects and very expensive cycle interruptions. Less post-weld clean up means less grinding.
