Multiple Choice

The ______ is the cone-shaped sleeve that holds the electrode to the torch.

That cone-shaped sleeve is the collet. In a TIG torch, the tungsten electrode passes through the collet, which sits inside the torch and grips the electrode when the back cap is tightened. This provides both a secure mechanical hold and good electrical contact, and the collet size must match the electrode diameter for a stable arc. The nozzle directs shielding gas, the insulator (ceramic) insulates and supports the assembly, and the retainer/back cap helps secure everything in place.
