EX309L-125T - Exocor Executive ER309L Stainless TIG Rod 1/8" (3.2mm) - 10lb

Achieve Flawless Stainless Welds with Exocor Executive ER309L

Take your TIG welding results to the next level with Exocor Executive ER309L TIG Rods. If you are a professional welder or a serious fabricator looking to join stainless steel to mild steel, this is the rod you need in your arsenal. The 3.2mm (1/8") diameter is perfect for medium-to-heavy gauge materials, providing excellent deposition rates while maintaining the control you expect from the GTAW process. Exocor's "Executive" line is famous for its bright, clean finish, which helps the puddle wet out smoothly and creates aesthetically pleasing beads with minimal oxidation.

Why choose 309L? It is designed to handle the metallurgical challenges of mixing different steels. When you melt stainless filler into a carbon steel base, the resulting weld metal chemistry changes. 309L is "over-alloyed" with Chromium and Nickel to compensate for this dilution, ensuring the final weld remains strong, ductile, and crack-resistant. It is also the go-to rod for applying a barrier layer on carbon steel before filling with 308L or other stainless alloys.

These rods perform exceptionally well with 100% Argon shielding gas, producing a stable arc and a fluid puddle that is easy to manipulate. The low carbon content protects your work from intergranular corrosion, ensuring the weld lasts as long as the base material. Packaged in a convenient 10lb tube, these rods are protected from moisture and dust, ready to perform whenever you strike an arc.

Why Welders Prefer Exocor Executive

• Superior Wetting: The clean surface finish allows the molten pool to flow smoothly at the toes of the weld.
• Crack Resistance: High ferrite number helps prevent hot cracking in rigid joints.
• Versatility: One rod handles stainless-to-steel, stainless-to-stainless (dissimilar grades), and overlay work.
• Easy Identification: Never guess what rod you are holding; identification is clear.
