OVERVIEW

Reliable Stainless Steel TIG Welding Rods

The Bonarc ER308L TIG Rod (2.5mm) is the go-to filler metal for general purpose stainless steel fabrication. Packaged in a convenient 5kg tube, these rods are designed to provide professional welders with consistent performance and high-quality results. As the most commonly used grade of TIG wire, ER308L is essential for any shop dealing with standard austenitic stainless steels.

This rod is specifically engineered for welding 18% Chromium - 8% Nickel stainless steels, commonly found in food service equipment, architectural structures, and general manufacturing. The "L" in ER308L stands for "Low Carbon," a critical feature that helps maintain the corrosion resistance of your base material after welding. Whether you are repairing a kitchen counter or fabricating a custom exhaust, the Bonarc ER308L ensures a strong, clean, and durable bond.

With a diameter of 2.5mm, this rod offers excellent control for medium-gauge materials, allowing for precise bead placement and manipulation of the weld puddle. The rods are manufactured to strict standards to ensure a clean surface finish, free from contaminants that could cause porosity or defects in your weld. Trust Bonarc for smooth feeding and stable arc characteristics.

FAQ

For TIG welding with ER308L, 100% Argon is the standard shielding gas. It provides excellent arc stability and prevents oxidation of the weld pool.

The 'L' stands for Low Carbon. ER308L has a maximum carbon content of 0.03%, whereas ER308 can have up to 0.08%. The lower carbon content in ER308L prevents carbide precipitation and intergranular corrosion.

Yes, ER308L is the recommended filler metal for welding 304 and 304L stainless steels.

Use DCEN (Direct Current Electrode Negative), also known as Straight Polarity, for TIG welding stainless steel.

The exact count varies by batch, but a 5kg tube of 2.5mm stainless steel TIG rods typically contains approximately 100-120 rods.

No, for welding mild steel to stainless steel, you should use an ER309L filler rod. ER308L is for stainless-to-stainless applications.

No, TIG welding uses an inert gas (Argon) to shield the weld, so no flux is required on the rod itself.

Standard TIG cut lengths are typically 1000mm (1 meter) or 36 inches, depending on the specific batch standard, but 1000mm is most common for metric brands like Bonarc.
