Maximum allowed water pressure is 5 bar. At a pressures higher than 5 bar, a
pressure reducer must be installed on the inlet of the cooler and limited to 4
bar.
The water flow is regulated automatically by a magnetic valve. The
water flow, in the worst case (Mark Duty Cycle 97%, ambient temperature
45°, water temperature 27°) is 2 litres per minute. The water out of the
controller has to be connected to one of the connectors of the laser cooling
plate to cool the laser. The water out of the laser cooling plate is the final
water out of the laser marking system.
An optional water chiller (part number L015148) is available from Domino.
Simmer Mode
The fibre laser has a simmer mode to ensure fast laser coding. As soon as
the laser is switched on there will be always a laser power output of below 5
mW present.
This is a hardware feature of the laser source which is always switched on.
