What are the 4 main parts of the GTAW torch (not including the torch body)?

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

Answer: (A)

In a GTAW torch, four parts work together to deliver shielding gas, hold the electrode, and seal the assembly. The gas nozzle directs shielding gas around the tungsten tip to protect the weld from contamination. The Collett body provides the housing that holds the Collett and forms the passage for the electrode. The Collett clamps the tungsten electrode in place, with the tightening action securing a reliable electrical connection and stable arc. The Torch cap, also called the Tail cap, threads onto the back of the torch to seal the assembly and keep the electrode secure while maintaining the gas flow. The electrode tip itself is part of the tungsten electrode, which is consumable and inserted through the Collett, not considered a separate torch component.
