308LSI045 - ER308LSi Stainless Steel MIG Welding Wire, .045 in, 33 lb Spool

Premium Industrial Grade ER308LSi Stainless Steel Wire

The Central Wire ER308LSi .045" MIG Welding Wire is a high-performance consumable designed for the rigorous demands of industrial stainless steel fabrication. This 33 lb spool is engineered for consistent feeding and superior arc stability, making it an ideal choice for manufacturing environments processing 304 and 304L stainless steel grades. The "Si" designation indicates a higher silicon content than standard 308L wire, which serves to increase the fluidity of the weld puddle. This characteristic is critical for achieving smooth tie-ins and minimizing post-weld grinding in cosmetic or sanitary applications.

Fabricators rely on this wire for its excellent corrosion resistance, attributed to its extra-low carbon content (0.03% maximum). This formulation helps prevent carbide precipitation during the welding process, protecting the integrity of the base metal against intergranular corrosion. The .045-inch diameter is well-suited for medium-to-heavy gauge materials, offering higher deposition rates while maintaining control. Whether utilized in automated robotic cells or manual welding stations, this wire delivers reliable conductivity and arc starts.

Josef Gas ensures that this product meets strict quality standards. The precision layer winding of the 33 lb spool ensures tangle-free payoff, reducing downtime associated with wire feeding issues. Compatible with standard industrial wire feeders and requiring Argon-based shielding gas mixtures (typically 98% Argon / 2% CO2 or Oxygen), this ER308LSi wire is a staple for food service equipment manufacturing, chemical tank fabrication, and general architectural stainless work.
