ER309LSi MIG Wire – High Silicon Stainless Wire for Smooth MIG Welding
The ER309LSi MIG Wire in 0.8mm is designed to deliver smooth, spatter-free welds with excellent wetting and bead appearance. This 15kg stainless steel spool is ideal for MIG welding dissimilar steels, especially stainless to carbon steel, and applications requiring a clean finish.
Optimized for Welding Dissimilar Steels
The ER309LSi MIG wire is primarily used for joining stainless steels like 304 or 309 to carbon steels. The “L” indicates low carbon content, which minimizes carbide precipitation and improves corrosion resistance, while the “Si” refers to its elevated silicon levels that improve wetting and visual quality.
Smooth Arc with Minimal Spatter
Thanks to its high silicon formulation, this MIG wire provides excellent arc stability and low spatter levels, reducing post-weld cleanup. Whether you’re welding in short circuit or spray transfer mode, the ER309LSi delivers clean, high-strength welds on various metal surfaces.
Perfect for General Fabrication and Repairs
From food-grade equipment to stainless piping and structural components, this 0.8mm stainless wire is a go-to choice for general metal fabrication. It’s especially useful for thinner sheet metals and applications that demand good visual finish and corrosion resistance.
The wire runs well on both manual and automated welding machines. Its 15kg spool is precision-layer wound to ensure consistent wire feed, minimizing downtime and feeding issues.
