ABSTRACT:
The invention is an improved collet design for arc welding torches. The collet tip is asymmetrically tapered. The collet tip bears on the interior surface of an adjacent sleeve which is appropriately flared in the rearward direction so as to receive the tapered collet tip. The sleeve also has an opening through which the electrode passes. The asymmetry of the collet-sleeve interaction causes the collet to be laterally displaced thereby gripping the electrode between the collet and the sleeve opening.
The improved collet also includes a spring fastener means for connecting the rear end of the collet to the back cap of the torch head.
