There is a gas valve in the handle, so this gun can be used with or without gas. The gas hose extends 6 ft beyond the end of the gun, the trigger wires have the correct single spade terminal connector connector and large lug for these welders, and the cable which carries the welding current has the correct twist lock connector to plug into the positive and negative connectors on the front of the welder. You can see the gas hose, trigger connector, and the welding current cable in the second picture.
This gun uses USAWELD 15 series replacement parts shown in the 3rd picture. Other than the parts installed on the gun, it does not include any extra replacement parts. Later models do not have the twist lock connectors for the welding current. Look at your gun and compare the photos to make sure you are purchasing the correct gun.
