Ugn, HN throttled my replies and lost the one I was writing. The nozzle is there for shield gas delivery. It also has a very short focal length making the focal point extremely distance sensitive so it has a wheel at the tip of the nozzle to keep the height constant. Since this is for welding in a vacuum you can omit the nozzle and even the wheel if you have a steady enough hand.
