b.Connect gun to gun connector making sure all pins and gas tube line up with appropriate holes in connector. Tighten gun by turning large nut on gun clockwise.

Synergic 7F Water Connections (for Water-Cooled Guns)

The Synergic 7F models must have a K682-2 Water Connection Kit installed. (see section under Electrical Installation; Water Connection Kit.

1)Using hose clamps provided with the K682-2 Kit, connect appropriate water hoses to the coolant inlet and outlet fittings on the back of the K682-2 Kit. Connect the other ends of the hoses to the appropriate ports on the water cooling units.

2)In the event the water line fittings on your water-cooled gun are incompatible with the female quick connects on the front of the K682-2 Kit, male quick connects are provided with the kit for installation on 3/16” I.D. hose (Customer to provide appropriate clamps). The feeder connectors self seal when disconnected.
