leak test 2 (system leak test)
Purpose: Tests for leaks to the atmosphere from the gas system.
Test description: The gas for the process selected is purged through the gas system. The metering console valves
(B1-B4), and the inlet valves (for the selected process) in the selection console are closed. Gas
pressure is now trapped in the system. The trapped pressure is monitored. Code number 14 (cut gas
channel number 1 failed) or 15 (cut gas channel number 2 failed) will be displayed if the pressure
drops faster than 0.14 bar/minute (2 psi/minute). Code number 13 will be displayed if the pressure
decreases within the acceptable limit of 0.14 bar/minute (2 psi/minute).
Procedure:
1. Perform System Leak Check on the CNC controller.
2. Turn OFF power and then turn ON power. This will purge gases from the system.
leak test 3 (proportional valve test in the metering console)
Purpose: Tests the Burkett valves (B1 and B3) in the metering console to ensure that they are working within the
correct parameters.

mild steel process are used for this test, because
there is a known flow rate.
Gas flows from the torch, and the Burkert valve that controls the plasma gas channel (B3) attempts
to maintain the set plasma gas pressure (monitored by P7 and P8) by adjusting the valve dynamically.
The signal percentage to the valve is measured (example: 65% on), and the value is checked against
the expected range (55% – 75%). The test is successful if the signal percentage is within the
expected range. Code number 14 (shield gas channel failed) or 15 (plasma gas channel failed) will be
displayed if the test fails. The same test is repeated for the Burkert valve that controls the shield gas
channel (B1).
For the next part of the test, the Burkert valve that controls the plasma gas channel (B3) is closed,
and the pressure is measured milliseconds later (pressure should decrease). The test is successful
if the pressure is below a given limit (0.69 bar [10 psi]). The same test is repeated on the shield gas
channel (B1).
Code number 16 (plasma ramp-down test failed) or 17 (shield rampdown test failed) will be displayed
if the signal percentage is out of the expected range. Code number 13 (test passed) will be displayed
if the signal percentage is within the expected range.
Procedure:
1. Install 130 A mild steel consumables in the torch and select the 30 A O

mild steel process.
2. Perform Metering Valve Flow Check on the CNC controller (test 3).
3. Turn OFF the power and then turn ON the power. This will purge gases from the system.
