b) Water cooling pressure:4
～
6 Bar at the water inlet;
c) Water inlet and outlet connector type: iHQB output fiber optic cable ϕ6 quick release connector;
QD output fiber optic cable ϕ8 quick release connector.
d) Water pipe type: iHQB fiber delivery cable connector outer diameter ϕ6 inner diameter ϕ4; QD
fiber delivery cable connector outer diameter ϕ8 inner diameter ϕ5.5
e) Cooling water quality: deionized water, distilled water, purified water; it is recommended to
replace the water once a month, and the replacement period should not exceed two months.
f) PH value of cooling water: 5.5
～
9;
g) The water cooler needs to be equipped with a filter element whose filter particle size is less than
100um; the filter element needs to be cleaned once a month.
h) Maximum cooling water temperature: 35
℃
;
i) The lowest cooling water temperature: 5
℃
greater than the saturated dew point temperature;
j) Additives in cooling water: meet the above PH value and solid particle size requirements;
Other requirements:
a) When starting the cooling system for the first time, check the entire water system and joint for
water leakage.
b) If the laser is not used for a long time, the cooling water inside the cooling system and the laser
inside should be drained, otherwise the laser equipment will be damaged.
c) Please use compressed gas below 0.5MPa when emptying water from the device. Failure to do
so may cause permanent equipment damage to cooling system.
CAUTION:
(1) Set the water temperature of the cooling system correctly according to the ambient
temperature. Setting the water temperature too high will result in the laser not working
properly. Setting the water temperature too low will cause condensation inside the laser or the
laser output head, which will cause damage to the laser;
