A metal inert gas welding torch having a wire guide assembly threadably secured at one end to a torch body and a collet nut assembly threadably secured to the other end of the wire guide assembly. 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.
