4.01 DIRECT PLUG MIG GUN INSTALLATION
Direct plug MIG guns install by directly inserting the rear connector plug into the feeder wire guide outlet (see
figure 2) and tightening the plug retaining screw. All models of MIG guns, except the Euro-Kwik guns, require a
control wire assembly to attach the MIG gun trigger leads to the feeder. The control wire assemblies plug into the
rear connector case of the MIG gun, and into the control wire receptacle on the feeder. Euro-Kwik connections are
installed by inserting the gun connection into the feeder receptacle, aligning the conduit plug first, then the gas
plug. Push until all fittings are seated, then tighten the nut hand tight as shown in figure 3.
