The chiller cools the laser source and cutting head. Overheating will trigger alarms, reduce laser output stability and even damage the laser.
Common Symptoms
- High temperature alarm pops up
- Unstable water temperature fluctuation
- Low water flow warning
- Water leakage
Possible Causes
- Dust clogging on condenser
- Insufficient or contaminated circulating water
- Water filter blocked
- Cooling fan failure
- Temperature parameter setting error
- Pipeline air trapped inside

Solutions
- Clean the condenser regularly to remove dust.
- Use deionized water, replace circulating water on schedule.
- Clean or replace the blocked water filter.
- Check cooling fan operation, replace if broken.
- Reset temperature control parameters.
- Drain air inside the water circuit.
Reminder
Shut down the machine before any chiller maintenance. Do not run the laser if cooling alarm exists.
