These collets can work with WP-17, WP-18, and WP-26 series torches. Collets directly hold the tungsten in place when you tighten the back cap and create the electrical contact necessary for good current transfer. Collets are generally made of standard grade copper or tellurium copper.Specifications | Compatibility | WP-17, WP-18, WP-26 torches |
