This makes the wedge collets more durable, lasting up to 10 times longer than standard split type collets.
With the wedge collet design the tungsten is put in direct contact with the collet body, the current transfer point is at the collet body creating better arc starting, arc stability, less resistance heating, and less low current arc wander.
The wedge collet design creates a better mechanical grip requiring less pressure on the back cap to secure the tungsten electrode, this helps to eliminate possible stripping of the threads on the torch head itself.
For use with CK series 2 gas saver consumables, these can also be used with WP type torches 9 and 20.
