42.0001.0694 - Fronius 3/32 TIG Torch Clamping Nut for Accupocket & TTG/TTW Series

Reliable Replacement Clamping Nut for Fronius TIG Torches

Keep your Fronius TIG torch operating at its best with this replacement Clamping Nut 3/32" (42.0001.0694). In the world of precision TIG welding, every component in the torch head matters. The clamping nut is responsible for applying the necessary pressure to the collet, locking the tungsten electrode firmly in place. This ensures that the electrical current is transferred efficiently from the torch body to the electrode, allowing for the smooth, stable arc that Fronius welders are famous for.

This specific clamping nut is designed for use with 3/32-inch (2.4mm) tungsten electrodes. It is a direct fit for several popular Fronius torch models, including the portable Accupocket 1600, the gas-cooled TTG1200A and TTG2200A, and the heavy-duty water-cooled TTW2500A and TTW3000A series. If you are experiencing issues with your tungsten slipping, difficult arc starts, or inconsistent amperage, a worn or damaged clamping nut could be the culprit.

Why Choose Genuine Parts?

While generic parts exist, using genuine Fronius consumables ensures that the threading and dimensions match your torch body perfectly. This prevents cross-threading damage to the torch head—a much more expensive repair—and ensures proper gas flow dynamics are maintained within the nozzle assembly. This clamping nut is built to withstand the high heat of TIG welding without seizing or deforming, providing reliable performance weld after weld.

Welders Supply recommends inspecting your torch consumables regularly. If you notice stripped threads or signs of overheating on your current clamping nut, swap it out immediately to avoid interruptions during critical jobs. This small investment in maintenance helps extend the life of your torch and improves the quality of your work. Whether you are welding stainless steel, aluminum, or mild steel, a secure electrode is the foundation of a good TIG weld.
