Conductor tubes install between the handle and the nozzle on a MIG (metal inert gas) gun to provide a path for the electrode wire in MIG welding tasks. Sometimes called goosenecks, the tubes can be swapped out for a tube of a different angle, radius, or material to allow access to hard-to-reach weld joints or reduce the amount of heat felt by the welder. They are compatible with MIG guns from specific brands and series. A complete MIG gun setup includes a nozzle, contact tip, gas diffuser, conductor tube, and gun liner.
