Large gas lens collets will directly hold the tungsten in place when you tighten the back cap and create the electrical contact necessary for good current transfer. They are generally made of standard grade copper or tellurium copper and all you need to do is select the correct collet for the size of tungsten being use.
Compatible for use on Tigama 230, WP9 & 20 type torches.
These collets are designed to be used with large gas lens 45V116S or 45V64S.
