Python Water Cooled Guns
K2212-xx push-pull guns require both the K590-6
water connection kit and the K2339-1 push-pull gun
connection kit. The hoses from the water connection
kit assemble directly to the push-pull gun bushing as
shown below. Secure the conduit from the python
gun in the gun bushing by using the thumb screw.
To install the K2339-1 Push-Pull Gun Connection Kit
in the POWER FEED™ 25M:
1. Turn power off at the welding power source.
2. Remove the gun from the wire feeder, if attached.
3. Remove the wire spool from the feeder, if present.
4. Loosen the socket head cap screw that holds the
connector bar against the gun bushing. Important:
Do not attempt to completely remove the socket
head cap screw.
5. Remove the outer wire guide, and push the gun
bushing out of the wire drive. Because of the preci-
sion fit, light tapping may be required to remove the
gun bushing.
6. Disconnect the shielding gas hose from the gun
bushing, if required.
7. For water cooled guns:
a. Install the hose assembly from K590-6 to
the rear of the POWER FEED™ 25M case.
