Coolant Recommendations
Use Cobra Coolant (Aluminum Protection), P/N 931-0060. Cobra Coolant
does not contain reactive sulphur or chlorine and does not react with copper,
brass or aluminum.

Gun Lead Connections
Power Cable - Air Cooled
A #2 AWG power cable is used on the Prince XL Millermatic Compatible.
The gun end of the cable has a fitting crimped to the copper cable strands.
This fitting is then threaded into the gun body with torque requirements of
100+5 in-lb. A setscrew holds the cable securely in the gun body and in the
Power Manifold with torque requirements of 55-60 in-lb.
Power Cable - Water Cooled
Prince XL Millermatic Compatible water cooled gun utilizes a power/water
cable with a #6 AWG cable inside a 5/16” diameter hose. When water is
used with this cable and the #10 water cooled gas cup (P/N 621-0065), the
system is rated at 450 amps @ 60% duty cycle. The gun end is threaded into
the gun body with torque requirements of 100+5 in-lb.
Conduit
The Prince XL Millermatic Compatible comes standard with a poly-lined
conduit, for feeding aluminum wire. The longer fitting with a shallow groove
is used on the gun end. A set screw located on top of the gun handle
secures the conduit in place. The cabinet end of the conduit is secured into
the Power Pin connector with a set screw.
Gas Hose
The gas hose is pushed over a barbed fitting on the end of the gun body
and secured by twisting the hose retainer to the end of the hose (shown next
page). The hose retainer is re-usable and can be removed and re-installed
as needed.
