Preventive Maintenance Program
Incoming air supply quality
To maintain system performance, it is important that the incoming air supply is clean. If the air supply has dirt, oil, or water
in it, components can become clogged or defective. An air supply of bad quality can cause the following problems:
 Decrease air flow
 Increase system errors (044, 053, 057, or 058)
 Decrease cut quality and performance
Oil in the torch head can cause a fire when the oil reacts with the oxygen cutting process. Also, unwanted material in
pressure sensors can cause false pressure readings.
The best solution, if possible, is to improve the quality of the air supply. Contact your OEM or regional Hypertherm
Technical Service team if you need advice on how to improve the quality of your air supply.
If you cannot change your air supply quality, you can replace the following components more frequently.
Metal dust inside the power supply cabinet
Plasma cutting makes metal dust. If metal dust collects inside the plasma power supply, it can decrease the life of the
fans and coolant pump motor.
The main power supply, chopper, or heat exchanger fans can operate more slowly, or failure of the fans can occur. This
can cause temperature-related errors (065, 066, 067, or 071). The coolant pump motor can become too hot and operate
incorrectly.
The best solution to extend the life of the fans and coolant pump motor is to clean inside of the power supply. For
instructions, see
Clean inside the power supply on page 14.
If metal dust has collected inside your power supply, you can replace the following components more frequently.
