ER309LSi MIG Wire 1.2mm – Reliable Stainless Steel Wire for MIG Welding
The ER309LSi MIG Wire in 1.2mm diameter is perfect for welding stainless steel to mild or carbon steel. This 15kg spool offers welders a dependable solution for fabrication, repair, and maintenance tasks in various industries like food processing and petrochemical.
Ideal for Dissimilar Metal Welding Applications
The ER309LSi MIG wire joins austenitic stainless steels such as 304 or 309 to carbon steel with ease. Its low carbon content (“L”) reduces carbide precipitation and improves corrosion resistance. Moreover, the added silicon (“Si”) promotes excellent wetting and arc stability. As a result, you get better bead quality.
Smooth Arc with Minimal Spatter
Thanks to its advanced alloy, this wire delivers consistent arc performance and reduces spatter. Whether you weld in short-circuit or spray transfer mode, the ER309LSi MIG wire produces clean, smooth welds. Consequently, you spend less time cleaning after welding and boost productivity.
Suited for Fabrication and Maintenance
This 1.2mm wire fits medium to heavy gauge materials well. It’s a versatile choice for structural steel fabrication, pipelines, pressure vessels, and stainless steel equipment. Because it offers excellent corrosion resistance, it ensures long-lasting welds in harsh environments.
The 15kg spool is precision wound for smooth feeding and fewer wire feed interruptions. It works with most MIG welding machines found in workshops or onsite.
