OVERVIEW

Professional Grade Stainless MIG Wire

The Bonarc ER308LSi HiSil .035" MIG Wire is a premium choice for fabricators requiring reliable, high-quality welds on stainless steel. Packaged in a substantial 15kg spool, this wire is designed for industrial environments where consistency and productivity are paramount. It is specifically formulated for welding austenitic stainless steels of the 18% Chromium - 8% Nickel variety, making it the go-to consumable for shops working with AISI 301, 302, and 304 grades.

One of the standout features of this wire is its "HiSil" (High Silicon) designation. The increased silicon content improves the fluidity of the weld pool, allowing for better wetting action at the toes of the weld. This results in a smoother, flatter bead that requires less finishing work. For Josef Gas customers, this means faster turnaround times on projects and a cleaner final appearance on architectural or food-grade stainless applications.

Reliability is key in production welding, and Bonarc delivers with precision winding that ensures smooth feeding through your MIG gun liner. Whether you are manufacturing tanks, piping systems, or general structural components, this 15kg spool offers the volume needed to keep your lines running without frequent changeovers. Trust Bonarc for consistent chemistry and superior arc stability.

FAQ

For MIG welding with ER308LSi, a mixture of 98% Argon and 2% CO2 is commonly used. Alternatively, a tri-mix gas (Helium/Argon/CO2) can be used for short-circuit transfer to improve bead profile.

The 'Si' stands for Silicon. This wire has a higher silicon content than standard ER308L, which improves the wetting action of the weld puddle and results in a flatter, smoother bead.

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

This is a 15kg (approximately 33lb) spool, designed for industrial wire feeders.

Yes, with the correct settings (typically short-circuit or pulsed MIG) and gas, it can be used in all positions, although flat and horizontal are easiest.

The 'L' denotes Low Carbon, which helps prevent intergranular corrosion (rusting from the inside out) in the heat-affected zone, maintaining the stainless properties of the base metal.

This wire is 0.035 inches (0.9mm) in diameter.

Yes, it is recommended to use a Teflon or plastic liner when feeding stainless steel wire to prevent contamination from steel liners and to ensure smooth feeding.
