2.2 Water Pipe and Gas Pipe
2.2.1 Water-cooled Interface
BT240S processing head is equipped with a set of waterways for cooling water, the direction of
its water entry and exit can be arranged at will. It is necessary to note that water cooling is
recommended when the laser power is more than 500 watts. The position and quantity of the water
cooling joint can be seen from Figure 3. The recommended water speed is listed below in detail,
and
please adjust the temperature of the cooling water at room temperature of ±5℃.
This water-cooled interface is designed as a closed-loop water-cooled system and can also be used
in cooperation with external free water supply to meet the requirements in the above list.
