A spidered collet is mounted in the collet nut assembly and forms a plenum chamber with the wire guide assembly and collet nut. A contact tip is gripped by the spidered collet and extends into the plenum chamber whereby the shielding gas cools the contact tip prior to the distribution of such gas into a nozzle.
