42.0300.0818 - Fronius Ceramic TIG Nozzle 8.4mm for TTG/TTW Torches

Precision Gas Coverage for Fronius TIG Systems

The Fronius Gas Nozzle Ceramic 08.4/020.0x33 is a critical component designed to deliver superior performance for the AccuPocket 1600 and associated TIG welding torches. Manufactured to the exacting standards of Fronius, this ceramic nozzle ensures that your shielding gas is directed in a laminar flow over the weld pool, protecting the molten metal from atmospheric contamination. In high-precision TIG welding, even minor turbulence in the gas flow can lead to porosity or oxidation; using genuine Fronius consumables guarantees the geometry and fitment required for optimal arc stability.

Constructed from high-grade, heat-resistant ceramic material, this nozzle is built to withstand the intense thermal cycles inherent in TIG welding. Whether you are operating at lower amperages with the gas-cooled TTG1200A and TTG2200A torches, or pushing higher currents with the water-cooled TTW2500A and TTW3000A models, this nozzle maintains its structural integrity. It resists cracking under thermal shock and minimizes spatter adhesion, which helps in maintaining a clean orifice for consistent gas distribution.

The dimensions of this nozzle—specifically the 8.4mm inner diameter and 33mm length—are engineered to provide a balance between gas coverage and joint accessibility. The 8.4mm opening is ideal for standard tungsten stick-outs and general-purpose welding applications, providing a wide enough gas envelope to shield the heat-affected zone without wasting expensive argon or helium. The 33mm length offers excellent visibility of the arc and puddle, allowing the welder to maintain precise control over the bead profile, even in tight corners or complex geometries found in pipe welding and fabrication.

Compatibility is key when selecting TIG consumables. This nozzle (SKU: 42.0300.0818) is the direct replacement part for the specified Fronius torch series. Using incorrect or generic nozzles can lead to poor thread engagement, gas leaks at the collet body, and inconsistent welding results. By choosing this authentic Fronius part, you ensure that your AccuPocket 1600 system operates at peak efficiency, delivering the clean, X-ray quality welds that the equipment is famous for.
