Support Equipment Required
• C.V. or C.C. Power Source of sufficient capacity for your needs.
• Regulated gas supply and hoses.
• Properly sized power leads from power source to wire feeder and
ground.
• Water source and hose capable of providing a minimum of 1 quart
(.95 liter) / min. at 45 p.s.i. when using water cooled guns.
Coolant Recommendations
Use a name-brand additive, which does not contain reactive sulphur or
chlorine and does not react with copper, brass or aluminum or create a
custom mix using this formula:
Use 3 Gallons (11.4 Liters) Distilled water.
Use 1 Gallon (3.8 Liters) ethylene glycol.
Use 1 tsp (5 ml) liquid glycerin
The Coolant rate should be 1 quart (.95 liter) / minute at 35 p.s.i.
Gun Lead Connections
Power Cable - Air Cooled
A #2 AWG power cable is used on the Python
®
air cooled gun. The gun end
is threaded into the gun body with torque requirements of 100+5 in-lb. The
power cable fitting connects to the Power Block in the Cobramatic
®
wire feed
cabinet.
Power Cable - Water Cooled
The Python
®
water cooled gun utilizes a power/water cable with a #4 AWG
cable inside a 5/8” (16MM) 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 250 amps @ 60% duty cycle. The gun end is threaded into the gun body
with torque requirements of 100+5 in-lb.
IMPORTANT:
Water cooled guns MUST be WATER COOLED
Conduit
The Python
®
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.
