58 Powermax30 AIR Operator Manual 808840
5 – Maintenance and Troubleshooting
Internal compressor LED faults
The internal compressor LED and the temperature LED illuminate while
the machine is powered ON.
The internal compressor may have overheated. Allow the power supply to cool for 4 minutes before
using it again. (See Understand duty-cycle limitations on page 46.)
When the internal compressor overheats, the compressor and temperature LEDs remain
illuminated for 4 minutes.
The system does not prevent you from firing the torch before the 4 minutes
elapses. However, if you begin cutting before the compressor has time to
fully cool down, the same fault is likely to occur again.
Place the power supply right-side up on a level surface. Laying the power supply on its side can
prevent proper air circulation needed to cool internal components. It can also cause the air filter to
divert air away from the torch.
Inspect and replace the consumables if they are worn or damaged. Always replace the nozzle and
electrode together. See Inspect the consumables on page 55.
Was the system stored in temperatures below freezing? If so, ice might have formed inside the
power supply. Move the power supply to a warmer location to allow the ice to melt.
If none of these troubleshooting steps resolves the issue, a qualified service technician must
service the system. Contact your distributor or use the information in the front of this manual to
contact Hypertherm Technical Service.
The internal compressor LED and the temperature LED blink alternately
when the machine is powered ON.
Release the trigger and restart the power supply. The system automatically disables itself when the
power supply is turned on while the torch trigger is pulled.
