6) Installation of gas pipes requires professional installation personnel, and the initial installation
requires air exhaust. Make sure that the pipes are clean before connection to the machine tool.
2.6 Connection to Waterway
The water cooling machine outputs two waterways, high-pressure waterway and low-pressure waterway. The high-pressure
water flows to the optical fiber plug and the cutting head. Pay attention to the direction of water inlet and outlet, make water
first flow through the optical fiber plug and then through the laser cutting head. Low-pressure water flows to the optical
fiber devices. Due to different brand of optical fiber device, the type of waterway connection may be different, and the
specification of joint pipe also may be different. Please recognize the flow direction and mark number of waterway, and
correctly connect to the waterway with water pipes which are attached to the machine.
Refer to the waterway schematic diagram in the standard files for details.
Attention points of waterway installation
1) Non-mineral purified water, distilled water or deionized water is added to the water-cooling machine, and it is forbidden
to add corrosive liquids or water with impurities.
2) When adding water, avoid unnecessary contact with water (for example, touch water by hand). All auxiliary equipment
such as pumps and hoses should be used only for this water cooling machine.
3) Before turning on the water-cooling machine, check its water level, and it is strictly prohibited to turn on the
water-cooling machine if there is no water or water level is too low, in order to avoid damage to the water-cooling
machine. It is strictly prohibited to squeeze and tread on inlet or outlet pipes of the water-cooling machine in order to
keep the waterway unimpeded.
4) At a temperature of below 0℃, in case of long-time downtime, discharge cooling water from the water-cooled machine,
laser and water pipes in order to prevent cooling water from freezing due to low temperature, which may cause damage to
the equipment and pipeline.
5) It is recommended to completely replace water in the water-cooling machine every two to three months.
