OVERVIEW

Smooth Flowing Stainless Wire for Professional Welders

Take your stainless steel welding to the next level with the Bonarc ER308LSi HiSil MIG Wire. If you are looking for a wire that runs smoothly and leaves a professional-looking finish, this is the ideal choice. The "HiSil" formula means this wire contains extra silicon, which acts as a deoxidizer and increases the fluidity of the weld puddle. This allows the metal to wash out better towards the edges, creating a flatter bead that looks great and is easier to finish. It is the perfect solution for welders who want to minimize grinding time and maximize productivity.

This 15kg spool of 0.030-inch wire is built for serious fabrication work. Whether you are working on automotive exhaust systems, kitchen equipment, or custom stainless fixtures, this wire provides the consistency you need. It is designed to weld common austenitic stainless grades like 304 and 308, offering excellent crack resistance and mechanical strength. The low carbon content ensures that your welds remain durable and resistant to corrosion over time, even in challenging environments.

Compatible with standard MIG welding setups using DC+ polarity and Argon-mix shielding gases, the Bonarc ER308LSi is user-friendly and forgiving. The consistent diameter and high-quality winding prevent feed issues, allowing you to focus on laying down the perfect bead. Upgrade your consumables inventory with this reliable stainless wire and experience the difference that high-quality filler metal makes in your fabrication process.

FAQ

The 'Si' stands for Silicon. ER308LSi has a higher silicon content (0.65-1.00%) compared to standard ER308L. This improves the wetting action and fluidity of the weld puddle, resulting in a smoother bead and flatter profile.

For MIG welding with ER308LSi, a mixture of Argon with 1-2% Oxygen or 2-5% CO2 is typically recommended to ensure arc stability and good penetration.

Yes, ER308LSi is the standard filler metal for welding 304 and 304L stainless steels.

This product comes on a 15kg (approximately 33 lbs) spool.

This wire is designed for use with Direct Current Electrode Positive (DCEP), also known as Reverse Polarity.

No, this is a solid MIG wire that requires an external shielding gas.

The 'L' stands for Low Carbon. This indicates a maximum carbon content of 0.03%, which helps prevent intergranular corrosion (carbide precipitation) in the weld zone.

This wire has a diameter of 0.030 inches (0.8mm).
