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.
The coolant flow rate should be a minimum of 15 GPH (1 qt/min) between
35 and 45psi. Contact the re-circulator manufacturer for specifications on
pressure.
Gun Lead Connections
Power Cable - Air Cooled
A #2 power cable is used on the Python
LX gooseneck gun. The gun end of the
cable is stripped to the copper strands and
wrapped with a copper strip. A setscrew
holds the cable securely in the gun body
with torque requirements of 55-60 in-lb.
The cabinet end of the cable is equipped
with a 1/2" ring lug which attaches to the
top hole on the side of the power block.
Supplied with this gun is a 3/8-16x5/8" bolt, a 3/8" spring lock washer and a
5/8" flat washer to attach the ring lug to the power block.
Power Cable - Water Cooled
Python LX 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.
These connections utilize a conductive sealant and are tightened with torque
requirements of 100 + 5 IN-LB.
Conduit
The Python LX gun 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.
