This detailed product description presents the premium quality ceramic welding torch head (gas nozzle) by Wieländer+Schill, specifically designed for TIG (Tungsten Inert Gas) welding applications. This critically important component is essential for precise and stable arc guidance, as well as ensuring optimal shielding gas flow during the most demanding automotive body and metalworking tasks.
The ceramic gas nozzle with part number 337130 is a fundamental consumable for TIG welding technology. It is excellently suited for TIG welding torches of type SR 17, SR 18, and SR 26 manufactured by Wieländer+Schill. The ceramic material ensures excellent thermal insulation and high resistance in high-temperature welding environments, minimizing wear and the risk of failure.
The precisely shaped nozzle size (size 6) guarantees optimal shielding gas flow, which is essential for achieving high-quality, slag-free weld seams, especially on sensitive materials such as aluminum or stainless steel.
Excellent Heat Resistance: The ceramic material maintains its structural integrity even at extremely high temperatures, ensuring a long service life even under intensive use.
Precise Gas Flow: The precisely machined internal geometry ensures a stable and laminar (layered) flow of shielding gas around the electrode and the workpiece, preventing air ingress and oxidation.
Compatibility: Widely compatible with the popular SR 17, SR 18, and SR 26 series TIG torches, ensuring easy replacement and integration into existing systems.
Durability: The excellent wear resistance of the ceramic reduces the need for frequent replacements, thus increasing workshop efficiency.
Ideal for Fine Work: Size 6 is the ideal choice for welding tasks where access is restricted or where a finer finish on the weld seam is required.
The product specifications ensure precise fitment and reliable performance under the strictest professional requirements.

The size 6 ceramic nozzle (with an internal diameter of 9.5 mm) creates a balance between shielding gas coverage and welding precision. The length of 47.0 mm ensures that the nozzle maintains the correct distance from the welding zone while providing sufficient protection for the electrode and the weld pool.
The outer dimensions (17.2 mm x 17.2 mm) reflect the standard design of the nozzle retainer part, ensuring a tight and heat-loss-free fit with the corresponding collets.
During TIG welding, the nozzle is continuously exposed to arc radiation and high temperatures. Compared to traditional materials, ceramic offers several advantages:
Heat Load Management: The low thermal conductivity of ceramic minimizes the heating of the nozzle, which stabilizes the welding process and reduces the risk of nozzle cracking.
Electrical Insulation: Although the arc is created via the tungsten electrode during TIG welding, the excellent dielectric properties of the ceramic ensure that the nozzle does not become an unintended contact point for the arc, which would cause immediate damage.
Chemical Stability: The ceramic resists the corrosive effects of gases generated during the welding process and residues from welding materials.
Besides size 6, other sizes are available in the Wieländer+Schill portfolio, allowing for fine-tuning of welding parameters for the specific task:
Gas Nozzle, Ceramic, Size 7 (Part No.: 337131): With an inner diameter of 11.0 mm and a length of 47.0 mm. For applications requiring higher gas flow.
Gas Nozzle, Ceramic, Size 5 (Part No.: 337132): With an inner diameter of 8.0 mm and a length of 47.0 mm. For smaller, more precise welding spots.
All these accessories have the same length of 47.0 mm and are compatible with SR 17, SR 18, and SR 26 torches, allowing the user to flexibly choose based on the required gas coverage and accessibility.
This ceramic gas nozzle is an integral part of the Wieländer+Schill professional welding technology portfolio, guaranteeing reliability and excellent work quality for every welding project.
