The Water-Cooled MIG Direct Mount - DOCKING SPOOL®/Weld Body Combination accommodates multiple Water-Cooled Nozzle Assemblies. This arrangement is readily adaptable to Dedicated or Automatic Welding applications. The equipment consists of four (4) basic components: a utility station, an intermediate utilities combination assembly, a High Deposition (H.D.) DOCKING SPOOL®/Weld Body Combination, and a Water-Cooled Nozzle. The H.D. DOCKING SPOOL®/Weld Body Combination is the principal component in this welding equipment arrangement. It accepts the utilities at the top end of the Spool and provides a means of accepting the water-cooled nozzle at the lower end. Several features important to a welding system are provided. Incorporated within the water channels of the DOCKING SPOOL® are check valves which provide a means of retaining residual water in the lines when the nozzle assembly is removed from the DOCKING SPOOL®/Weld Body Combination. In addition a POSIT® Ring is provided at the upper end of the DOCKING SPOOL® which allows positive location in a Mounting Bracket to maintain dimensional stability.

These welding assemblies are designated by Models. The Model NCM has a current capacity 500/600 amperes in argon shielding. These accommodate slip-in current tips fastened by a collet action nut. The wire diameter range with hard wire is .030" - 1/16", cored wire .035" - 7/64" and aluminum wire range of 3/64" - 3/32".
