What is the difference between Weldtech SG2 & Filco SG3 MIG wire ?
Both are classified as A18, but the SG3 wire has a higher silicon and manganese content. This means it can be run at high amperages giving productivity benefits and that it flows better than the SG2 giving it welder appeal.

Weldtech A18 is an SG2 (now designated G3sil) precision layer wound mild steel MIG welding wire.
Filco 19/12 is an SG3 (now designated G4sil) precision layer wound mild steel MIG welding wire, manufactured by Italian producers INE spa.

A31 MIG Wire is for the joining or overlay of Creep resistant Manganese Moly steels operating at elevated temperatures.
Filco D2, A32 MIG wire is a low alloy welding wire for welding high strength steels.
