Description

The BriteArc ER309LSi 1.2mm MIG wire in a 15 kg spool is designed for welding dissimilar metals and stainless to mild steel joints. Known for its superior crack resistance and clean bead finish, this stainless steel wire is widely used in fabrication, maintenance, and repair welding across various industries. With low carbon levels and enhanced silicon content, this wire ensures strong, corrosion-resistant welds that hold up over time.

As an ER309LSi 1.2mm MIG wire, it is particularly well-suited for joining stainless steels to carbon steels or for austenitic stainless overlays. The high alloy content improves crack resistance while the silicon improves puddle control and bead shape. You get smooth arcs, low spatter, and excellent slag removal—ideal for both pulse and spray transfer MIG applications.
