Hold your tungsten electrode in place during TIG welding with these collets. Slide them into a collet body or gas lens, and secure by screwing the back cap onto your torch.
Collets forceramicnozzles are split into two sides. When you tighten the back cap, the sides squeeze together to grip the tungsten. These are the most common collet style, but the split is a weak area where they deform over time.
