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 10 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 Lincoln Compatible gun. The gun
and Power Pin ends of the cable are stripped to the copper strands and
wrapped with a copper strip. 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
Python Lincoln 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.These connections utilize a conductive sealant and are tightened with
torque requirements of 100 + 5 IN-LB.
Conduit
The Python Lincoln 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 BLACK 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
below). The opposite end of the BLACK hose is pushed over a barbed fitting
in the Power Pin. The hose retainer is re-usable and can be removed and
re-installed as needed.
