36 Freedom 38 PPA Service Manual 809010
1 – Troubleshooting
Troubleshoot air flow issues (air compressor)
The air pressure for this system must be between 5.9 bar – 9.3 bar (85 psi – 135 psi) to operate the on-board plasma
cutting system.

If needed, you can use the plasma cutting system to test whether proper air flow is
reaching the torch. See
Run a gas test on page 46.
If the system’s air pressure is too low, if there is no air pressure at all, or if the 0-12, 0-20, or 0-22 fault code displays on
the plasma cutting system’s LCD screen, do the following checks in the order listed:
1. Does the 0-12 fault code display on the plasma cutting system’s LCD screen?
 If yes, install a new air filter element in the plasma cutting system. See page 114.
 If no, continue with the next step.
2. Turn off the system. Inspect the consumables in the torch. Are they installed incorrectly?
 If yes, remove the consumables, then install them properly.
 If no, continue with the next step.
3. Inspect the torch. Are there any signs of damage that might be causing air to leak?
 If yes, have a Hypertherm distributor or authorized repair facility examine the torch and torch lead.
 If no, continue with the next step.

If you have another torch available, you can also connect that to the plasma supply to
see if the same problem occurs.
4. Is the valve open that is used to drain condensate from the air tank?
 If yes, rotate the lever underneath the front panel to close the valve. See Drain the condensate from the air tank
on page 61.
 If no, continue with the next step.
5. Is the valve open that is used to drain condensate from the air/oil separation tank?
 If yes, close the valve underneath the tank. See Drain the condensate from the air compressor’s air/oil separation
tank on page 65.
 If no, continue with the next step.
6. Check the oil level in the air compressor. Is the oil level too low?
 If yes, add oil to the compressor’s air/oil separation tank, as needed. See Check the oil level in the air
compressor on page 63.
 If no, continue with the next step.
