1.3 Operation Conditions and Safety Instructions

Please read the following instructions carefully. Product reliability and lifetime probably be
affected if not following the user manual.
1. Make sure that the 48VDC power supply is connected in the correct way. Wrong
connection or input voltage might damage the product.
2. Make sure that the bending diameter of the fiber cable is larger than 15cm in
anytime. Otherwise power will decrease or the laser may even be damaged.
3. The speed of the fan is adjustable according to ambient temperature. Make sure that
minimum10cm air gaps behind and in front of the fiber laser. And the air flow direction of the
system should be the same as the laser. Short ventilation distance and wrong air flow
direction will lead to the laser temperature rises.
4. The default running ambient temperature range is 0~40℃. Enable the "Performance
Mode" by GUI, the average output power can be increased by 20% under this mode when
at the same cut-off frequency. The operational temperature range 5-35℃ is recommended
at this point. The sensor might be alarm if temperature beyond 5-35℃ and continuous
emitting the laser under the high energy. (Please refer to the introduction of monitoring
function and alarms in Chapter 3.2.) It is recommended that the operating temperature range
of the laser is 10-30℃. Good heat dissipation is helpful to prolong the working life of the laser.
5. Due to the "thermal lens effect" of ordinary K9 glass optical lens in medium and high
power range application, the phenomenon of focus drift, spot size inconsistency or light output
instability might occur during material processing if using K9 glass optical field lens. Fused
silica lens is recommended.
6. Please keep the fiber laser source clean especially the laser output window. Please
remember to cover the output window when it's exposed to the open environment. Dust on the
