44.0350.1501 - Fronius Style 1.6mm Gas Lens for TTG/TTW Torches

Precision Gas Lens for Fronius TIG Systems

Maximize the performance of your Fronius TIG welding system with this high-quality 1/16" (1.6mm) Gas Lens. Designed as a direct replacement for part number 44.0350.1501, this consumable is engineered to fit a wide range of Fronius torches, including the popular TTG and TTW series. Whether you are operating a gas-cooled TTG1600 or a heavy-duty water-cooled TTW3000A, this gas lens ensures your equipment operates at peak efficiency.

The primary advantage of upgrading to a gas lens system is the creation of laminar gas flow. Unlike standard collet bodies which can create turbulent gas streams, the fine mesh screen inside this gas lens straightens the flow of argon. This results in a coherent column of shielding gas that provides superior protection to the weld pool, significantly reducing the risk of porosity and oxidation. This is particularly critical when welding sensitive materials like stainless steel, titanium, or aluminum where atmospheric contamination can compromise weld integrity.

Another significant benefit is the ability to extend the tungsten electrode further past the nozzle cup. Because the gas column remains stable for a longer distance, welders can increase stick-out to gain better visibility of the puddle and arc, especially when welding in tight corners, fillets, or restricted access areas. This improved visibility leads to greater precision and reduced operator fatigue.

This gas lens is compatible with 1.6mm (1/16") tungsten electrodes and fits seamlessly into the torch head of compatible Fronius models. It is constructed from durable, high-conductivity brass to withstand the thermal cycles of industrial welding environments. Regular inspection and replacement of gas lenses are recommended to maintain optimal shielding gas performance.
