Condition of the air supply

Make sure that the air supply is clean. If the air supply contains dirt, water, or oil, components can become clogged or defective. An air supply that is not clean can cause these problems:
  • Decreased air flow
  • Increased system gas errors
  • Decreased cut quality and performance
  • False error codes from bad pressure sensors

For recommendations about how to keep your air supply clean, speak to your cutting machine supplier or or regional Hypertherm® Technical Service team.

If the air supply is not clean, replace these components more frequently:

Description Part number
Air filter element 011110
Quick-disconnect torch 420221
Quick-disconnect torch receptacle 420220
Torch lead –1
Gas solenoid valve, pressure transducer –1
1 Part number can be different.

Oil in the torch head can cause a fire when the oil reacts with the oxygen-cutting process. If you find oil in the air supply, speak with your cutting table manufacturer or regional Hypertherm Technical Service team.
