What are the main components of a GTAW torch, from the front toward the back?

• A. Nozzle, Collet Body, Handle, Collet, Electrode, Cap
• B. Cap, Electrode, Collet, Handle, Collet Body, Nozzle
• C. Nozzle, Cap, Electrode, Collet, Handle, Collet Body
• D. Nozzle, Collet, Handle, Cap, Electrode, Collet Body

Answer: (A)

The main idea here is how a GTAW (TIG) torch is assembled from the front (the nozzle side) toward the back (the handgrip side). The front-most piece is the nozzle, which shapes the arc and delivers shielding gas. Immediately behind it sits the collet body, the housing that contains the clamping mechanism for the tungsten electrode. The handle is the gripping part of the torch, positioned behind the collet body. Inside the collet body sits the collet, which clamps the tungsten electrode that passes through it and extends toward the nozzle to form the arc. The cap threads onto the back end of the collet body, securing the electrode assembly and helping complete the gas path around the nozzle. This order—nozzle, collet body, handle, collet, electrode, cap—reflects how the torch is put together and how gas flow and electrode clamping are arranged. Other sequences would place the cap or the electrode in positions that don’t match how the components physically fit and function together.
