Gas system
On this screen you can monitor the status of the torch connect console and the gas connect
console. You can also see which valves are active when the gas is flowing. Active valves have gray
highlights. There are 2 view options for this screen
1. Text view – Refer to Figure 51 on page 187 for an example text-view screen. In text view, text
describes real-time gas pressures and currently-active valve states.

Both bar and psi units of measure are visible in this screen.
2. Diagram view – Refer to Figure 52 on page 188 for an example diagram-view screen. In
diagram view a diagram shows:

Real-time gas pressures and currently-active valve states.

Pressurized volumes and energized valves with color-coded highlights that illuminate when
active.

Pressure measurements and setpoints near the proportional valves and duty cycle (PWM)
sensors represented by the diagram.

This screen gives you the option to display either bar or psi units of
measure.
You can do 4 tests from this screen: Test Preflow, Test Cutflow, Test Pierceflow, and Gas Leak Test.
The gas leak test is only available on XPR cutting systems equipped with a VWI or OptiMix gas
connect console. Refer to
How to do a gas leak test (VWI and OptiMix) on page 338.
The test starts when you choose the button. The button becomes active, indicated with a red
highlight. The active valves are indicated with a gray highlight. The gases shown on Line A, Line B,
and shield are different depending on the process ID that you selected. The gases flow for 60
seconds unless you choose the same button or choose another button that interrupts the test.
