For the connection on the welding power source side, fit the convex portion of the connector with the
concave portion of the output terminal and firmly insert the connector, and then tighten by turning it
clockwise.

Connect the feed water hose of the welding torch to the feed water connection. (This operation is not
required for air-cooled torch.)
3.
Connect the gas hose to the gas connection port.
4.
Remove the cap of the torch switch socket and connect the torch switch cable (2-core) to the socket.
