Gas console operation
The gas console is an automated piece of equipment that requires very little operator intervention during normal
operation. All of the functions of the gas console are automatically controlled by the CNC. The CNC also receives
feedback regarding cut gas pressure and any errors from the gas console. Proportional valves can be checked using
the “Test Gas” feature of the Hypertherm CNC. For a generic CNC, skip steps 1 – 3 below and send appropriate gas
selection and gas pressure set point commands to the LPC I/O interface and check the output values as shown in step
4 below.
Note: The system must be in Laser cut mode (vs. Trial mode) in order for the test gas to work properly

pressure.
3. Push the “Test Gas” button. See the
figure to the right.
4. The gas type and pressure are displayed
on the main screen of the laser head
controller. The values shown on the

in the cut chart, within 5% or 1 psi,
whichever is greater.
