ER309LSi MIG Wire 1.6mm – For Strong Welds on Stainless and Mild Steel
The ER309LSi MIG Wire in 1.6mm diameter is engineered for welding stainless steel to carbon steel. Supplied on a 15kg spool, it’s built for heavy-duty fabrication, structural welding, and demanding maintenance work.
Great for Dissimilar Welding Tasks
This ER309LSi MIG wire makes welding different metals easier. It’s ideal for joining stainless steel (like 304 or 309) to mild steel. The low carbon content limits carbide precipitation, improving corrosion resistance. In addition, its high silicon level enhances arc stability and improves the wetting of the weld puddle.
Clean Welds with Less Cleanup
With minimal spatter and a steady arc, this wire helps you produce cleaner welds. It’s suitable for both spray and short arc transfer modes. As a result, it reduces post-weld finishing time and increases overall efficiency.
Built for Heavier Sections and Industrial Use
The 1.6mm diameter is best suited for thicker sections, structural frames, support columns, and pressure vessels. It’s a popular choice for industries like food-grade equipment, petrochemical systems, and general fabrication. Professionals rely on this wire when welding dissimilar metals in critical applications.
The precision-wound 15kg spool guarantees smooth feeding. This reduces downtime and keeps the arc stable during long runs. It also works with most industrial MIG welding machines.
