If your plasma cutting system uses shield water and is stored in ambient temperatures
at or below 0ºC (32ºF), Hypertherm® recommends that you
use these steps to remove shield water. These steps are for cutting systems that have a
VWI™ or OptiMix™ gas connect consoles.
-
Remove the shield water supply line to the gas connect console.
-
Access a source of compressed air that is clean and dry.
-
Use a regulator to adjust the compressed air to 5.52 bar (80 psi).
-
Connect the compressed air hose to the water inlet on the gas connect
console.
Note:
The air hose needs to adapt to a JIC 6 male fitting on the gas connect
console.
-
Use the XPR® web interface or
Computer Numerical Control (CNC) to select a process ID for a
water process (such as 2028).
-
Select Preflow from the Plasma Process
Selection menu.
Note:
During preflow, water mist will exit the torch nozzle for approximately
45 - 50 seconds.
-
Repeat the previous step until shield water mist is no longer visible exiting
the torch nozzle.
Note:
It can take 7 - 10 preflow cycles for the shield water mist to stop.
