SIFMIG ZERO SG3 x 1.0mm [18Kg]
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 uncoppered 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.
For use in all positions.
