42.0300.0823 - Fronius Style Ceramic TIG Cup 11.4mm for TTG/TTW Torches

Precision Ceramic Gas Nozzle for Fronius TIG Systems

The Fronius Gas Nozzle Ceramic 11.4/020.0x33 (SKU: 42.0300.0823) is a critical consumable designed for the high-performance demands of the AccuPocket 1600 and associated TIG welding torches. Manufactured to exact tolerances, this nozzle ensures the proper delivery of shielding gas to the weld pool, a fundamental requirement for achieving defect-free TIG welds. The nozzle features an internal diameter of 11.4mm, which provides a focused column of gas, ideal for standard welding applications where coverage and accessibility must be balanced.

Constructed from high-grade ceramic material, this nozzle is engineered to withstand the intense thermal cycling inherent in TIG welding. It resists cracking under thermal shock and maintains its structural integrity even during prolonged welding sessions at higher amperages. The 33mm length offers a standard profile that fits a wide range of joint configurations, allowing the welder to maintain the correct stick-out and arc length without obstruction.

This component is specifically compatible with a range of Fronius torch bodies, including the gas-cooled TTG2100A and TTG2250A, as well as the water-cooled TTW2500A and TTW3000A models. Proper maintenance of the gas nozzle is essential for system longevity; a damaged or clogged nozzle can lead to turbulent gas flow, porosity, and tungsten contamination. By utilizing this specific part, operators ensure seamless compatibility with their Fronius equipment, maintaining the high standards of precision expected from the AccuPocket line.

Whether used in manual fabrication or automated setups, the reliability of the gas nozzle directly impacts the stability of the arc and the cleanliness of the weld. This replacement part restores the original performance characteristics of the torch, ensuring that the shielding gas envelope remains laminar and effective against atmospheric contamination.
