Which option lists all four main parts of the GTAW torch (excluding the torch body)?

• A. Gas Nozzle, Collett body, Collett, Torch cap/Tail cap
• B. Gas Nozzle, Collet body, Collett, Torch cap/Tail cap
• C. Gas Nozzle, Collett body, Collett, Torch cap/Bottom cap
• D. Gas Nozzle, Collett body, Collett, Torch cap/Top cap

Answer: (A)

In GTAW torches, the four pieces that interact with the electrode and shielding gas (excluding the torch body) are the gas nozzle, the collet body, the collet, and the cap that closes the assembly (often called the torch cap or tail cap). The gas nozzle directs shielding gas to the weld area, protecting the molten metal. The collet body holds the collet and threads into the torch head, while the collet itself clamps the tungsten electrode when you tighten the collet nut. The cap threads onto the end of the assembly, sealing and holding the electrode in place; in many designs this piece is referred to as a tail cap. These four parts together cover gas delivery, electrode retention, and sealing, which is why they form the complete set excluding the body.
