44.0350.0338 - Short Back Cap L11A for Fronius TTG and TTW TIG Torches

Compact Precision for Fronius TIG Torches

In the demanding world of TIG welding, accessibility is often the deciding factor between a perfect weld and a frustrating struggle. The Short Torch Cap L11A is an essential accessory for professional welders operating Fronius Accupocket 1600, TTG, and TTW series torches. Designed to replace the standard long back cap, this compact component significantly reduces the overall length of your torch head. This reduction in profile allows you to maneuver the torch into tight corners, inside pipe diameters, and around complex roll cage geometries with ease. Whether you are a professional fabricator working on intricate automotive components or a maintenance welder repairing equipment in situ, having a short back cap in your kit ensures you are never limited by the physical size of your tools.

This replacement cap, corresponding to part number 44.0350.0338, is engineered to meet the rigorous standards expected by users of premium Fronius equipment. It provides a secure and reliable seal for the back of the torch, preventing shielding gas leaks that could otherwise compromise your weld quality through oxidation or porosity. The cap works in conjunction with your collet and collet body to apply the necessary axial pressure to the tungsten electrode, holding it firmly in place during operation. Because of its shortened length, it requires the use of shorter tungsten segments—often referred to as stubs—making it an excellent way to utilize the remaining length of electrodes that have become too short for standard long caps, thereby reducing waste.

Seamless Compatibility and Performance

The L11A Short Cap is specifically molded to fit a wide range of Fronius torch bodies, ensuring a hassle-free installation. It is fully compatible with the air-cooled TTG1200A and TTG2200A models, as well as the heavy-duty water-cooled TTW2500A and TTW3000A torches. This versatility makes it a valuable stock item for fabrication shops running multiple Fronius machines. Instead of struggling with a full-length torch in a confined wheel well or inside a hydraulic manifold, simply swap to this short cap to gain the clearance you need without sacrificing arc stability or gas coverage.

Durable and Reliable Construction

Manufactured from high-heat resistant phenolic materials, this back cap is built to withstand the intense thermal cycles inherent in TIG welding. The threaded connection is precise, ensuring it screws smoothly into the torch head without binding or cross-threading, which protects the delicate threads of your torch body. The integrated O-ring provides a positive gas seal, which is critical for maintaining the inert atmosphere required for high-quality welds on sensitive materials like stainless steel and aluminum. By choosing this high-quality replacement part from Josef Gas, you ensure the longevity of your torch and the consistency of your welding results, job after job.
