2. Gas interface
Installation connection: cutting gas 1, nozzle cooling gas 2
Notice:
The maximum pressure of cutting gas is 25bar (2.5Mpa).
The cutting gas quality shall meet the requirements of gas quality in accordance with ISO
8573-1:2010: solid particles - class 2, water - class 4, oil - class 3. The purer the cutting gas,
the longer the life of the protective lens.

Installation connection: water-cooled water inlet port 2A, water-cooled water outlet port 1A
Notice:
Deionized/distilled water (conductivity < 10 μ S/cm) specified by the laser manufacturer is
recommended.
Recommended cooling water setting value: cooling water pressure ≤5bar (0.5Mpa), water flow rate ≥
2.0l/min.
Please refer to the dew point table to set the cooling water temperature to prevent condensation on
the optical components.

4. Electrical Interface
PWE and aviation plug interface waterproof precautions:
1. PWE interface and air plug interface are equipped with dust plugs from the
factory. If the dust plug does not fall off, the protection level of IP64 can be
achieved; at the same time, when the PWE cable and the air plug cable are
well connected, IP64 can also be achieved;
2. After the dust plug is removed, the protection level of IP64 cannot be achieved.
If it encounters spraying or flushing at this time, it will cause water to enter the
product and affect the function;
3. Ensure that the water circuit is connected well, and the water pipe interface is
tightened before removing the dust plug to prevent the water pipe from
accidentally loosening and water rushing to the interface, causing the product
to enter the water;
4. When adjusting the wiring, remove the dust plug for wiring. It is recommended
to keep the removed dust plug of the PWE interface. Install the dust-proof plug
as soon as possible after the stitches are removed to prevent accidental water
ingress in the transfer, water connection and other links.
