62171200 - Bonarc ER308LSi .045" Stainless MIG Wire (15kg Spool)

Premium Stainless Steel Welding Wire for Industrial Fabrication

The Bonarc ER308LSi .045" MIG Wire is a high-performance stainless steel welding consumable designed for professional industrial applications. Packaged in a substantial 15kg spool, this wire is engineered to meet the rigorous demands of continuous manufacturing environments. The "LSi" designation indicates a low carbon content combined with high silicon, a formulation that significantly enhances the welding characteristics of the material.

This wire is specifically developed for welding austenitic stainless steels of the 304 and 304L grades. The higher silicon content improves the fluidity of the weld pool, resulting in exceptional wetting action. This allows the molten metal to flow more smoothly into the toes of the weld, creating a flatter bead profile and reducing the need for post-weld grinding or finishing. The low carbon content is critical for maintaining corrosion resistance, particularly by minimizing carbide precipitation at the grain boundaries, which protects the integrity of the weldment in corrosive environments.

Key Performance Benefits:

• Superior Wetting: The high silicon formula ensures the weld metal washes in smoothly, ideal for fillet welds and cosmetic applications.


• Consistent Feeding: Precision layer winding prevents tangles and ensures stable arc characteristics, even at higher wire feed speeds.


• Versatility: Suitable for a wide range of industries, including food and beverage processing, pharmaceutical equipment manufacturing, and architectural metalwork.

For fabricators requiring reliable, high-quality stainless steel joins, the Bonarc ER308LSi offers the perfect balance of mechanical strength and aesthetic finish. It is compatible with standard MIG welding equipment and performs best with Argon/CO2 or Argon/Oxygen shielding gas mixtures.
