Waterway installation
The HW980 handheld welding head is equipped with a set of cooling water
channels. It should be noted that when the laser power is greater than 500
watts, it is recommended to use water cooling. The location and number of
water-cooling interfaces can be seen in Figure 3, and the table below details
the recommended water flow rates. The water-cooling interface is designed as a
closed-loop system and can also be used with external water supply, but it
must meet the requirements in the list.
