OVERVIEW

Smooth Running Stainless TIG Rod for Precision Welds

When you are under the hood TIG welding stainless steel, you need a filler rod that flows smoothly and wets out perfectly. The Bonarc ER308L .035" TIG rod delivers exactly that. Designed for welders who demand control and aesthetics, this rod produces a clean, stable arc with minimal spatter. The 0.035-inch diameter is the perfect size for fine detail work on thin sheet metal, exhaust tubing, or sanitary stainless piping, allowing you to dab the puddle with precision without chilling it too quickly.

This rod is the go-to choice for welding standard 304 and 304L stainless steels. The 'L' stands for Low Carbon, which means you don't have to worry as much about the weld decaying or rusting out from the inside later on. It lays down a bright, shiny bead that requires minimal post-weld cleaning, saving you time on grinding and polishing. Whether you are fabricating a custom kitchen backsplash, repairing a stainless tank, or working on automotive headers, this rod gives you the professional look you are after.

The 5 kg tube keeps your rods organized and straight, preventing them from getting bent or contaminated in your shop environment. With Bonarc ER308L, you get consistent feeding and a puddle that does what you tell it to, making those stack-of-dimes welds easier to achieve. It is compatible with standard 100% Argon shielding gas and DCEN polarity setups found in almost every TIG shop.

FAQ

ER308L is primarily designed for welding austenitic stainless steels like AISI 304 and 304L. It can also be used for 308 and 321 grades in certain temperature ranges.

100% Argon is the standard shielding gas for TIG welding with ER308L rods to ensure a clean, oxidation-free weld.

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

For TIG welding stainless steel with this rod, you should use DCEN (Direct Current Electrode Negative), also known as straight polarity.

These rods have a diameter of 0.035 inches (approximately 0.9mm), making them suitable for welding thin-gauge materials.

No, for welding mild steel to stainless steel, an ER309L rod is typically recommended. ER308L is for stainless-to-stainless applications.

This product comes in a 5 kg (approximately 11 lbs) protective tube.

Yes, stainless steel should always be cleaned with a dedicated stainless steel wire brush and acetone to remove oils and oxides before TIG welding.
