0.8mm Mild Steel MIG Wire - 5kg Reel
ER70S-6, G4Si, SG3
Typically what is called better quality standard MIG wire. In truth the G4Si wire is generally regarded as a better quality MIG wire because they both fall into the ER70S-6 category. G4Si is a stronger wire than more commonly sold G3Si. Not only is it stronger, it flows more easily and will produce neater welds compared to the lower spec.
