63063200 - Bonarc ER308L Stainless TIG Filler Rod 3.2mm - 5kg Tube

Bonarc ER308L TIG Rod – The Professional's Choice for Stainless Steel

When it comes to TIG welding stainless steel, the Bonarc ER308L 3.2mm rod is the reliable workhorse you need in your shop. Designed for welding the most common stainless grades like 304 and 304L, this filler rod produces bright, clean, and strong welds that look as good as they hold. If you are fabricating custom exhaust systems, repairing kitchen equipment, or building stainless tanks, this rod gives you the control and quality necessary to produce professional results every time. The 3.2mm (1/8 inch) thickness is perfect for filling larger gaps or laying down beads on thicker materials where smaller rods just can't keep up.

One of the biggest challenges in welding stainless steel is maintaining corrosion resistance after the weld is done. Bonarc ER308L solves this with its "Low Carbon" formula. By keeping carbon levels extremely low, it prevents the weld zone from losing its stainless properties, ensuring your project won't rust out at the seams later. This makes it ideal for everything from marine hardware to brewery tanks. The rod flows smoothly under the TIG torch, wetting out the edges of the puddle perfectly so you can focus on your travel speed and dab rhythm rather than fighting the puddle.

This product comes in a convenient 5kg tube, giving you plenty of material for substantial projects without the bulk of industrial drums. The reusable tube keeps your rods straight, organized, and clean—free from shop dust and moisture that can ruin a stainless weld. Compatible with any standard TIG welder set to DCEN with pure Argon gas, the Bonarc ER308L is a versatile addition to any welder's arsenal. Don't settle for generic filler metals that sputter and pop; choose Bonarc for a smooth, buttery arc and a finish you can be proud of.
