Hi, Clara here, long time no see, hoping you guys happy and luck in the new year. Today we are going to tell a solution of Raycus laser problem. You can find the issue and corresponding solution in this video. If you are first time being here, please don’t forget to subscribe to this channel, give me your like and share the video, it is important to me, thank you. Let’s get started.
First of all, to reiterate the premise, whether it is your machine or laser, as long as it is within the warranty period, please contact your supplier for help and solutions as soon as possible. Don't look for similar questions and answers online and try to figure it out on your own. Personally, I don't think it's a good idea.
In the summer, or after heavy rain, or when the local humidity is relatively high, we turn on the machine in the morning, or the laser is restarted after a period, such as a week, we may encounter condensation and high humidity alarms.
The reason for the alarms is temperature discrepancy. When the equipment is not running, the temperature difference between the inside and outside of the laser is large, resulting in the condensation of moisture in the air inside the laser. When the laser is turned on again, the internal ambient humidity is self-tested. When the detection humidity is greater than 70%, the laser will report a humidity alarm.
The humidity alarm is calculated by detecting the humidity of the air inside the laser. The dew point alarm is calculated by detecting the dew point temperature of the air inside the laser.
Here simply put, the dew point is the temperature that water vapor become the temperature of liquid water. In different environments, this dew point is different. The chart here, you can take a reference.
Speaking of which, what are the solutions against the two alarms?
1: Equip the lasers with separate air-conditioned rooms.
2: When starting the laser, first turn the key switch of the laser to OFF, turn on power of the laser, and let the air conditioner run for about 15 minutes before turning on the chiller. When the temperature of the water cooler reaches the set temperature, turn on the laser by turning on the laser key switch to the REM.
In order to save time, the next day, we can also turn the key switch of the laser to OFF on the first day, and then turn off the power switch of the laser after the temperature of chiller returns to room temperature. After this operation, the air conditioner will continue to dehumidify the inside of the laser to prevent the temperature difference between the inside and outside after the power is off, resulting in condensation or humidity alarm.
In addition, the laser may generate a humidity or dew point alarm during operation. This may be due to the cooling effect of the laser being poorly reduced due to the clogging of air conditioning filters. We need to clean the filters and air inlets and outlets of air conditioners.
That is all our topic today, hoping it will be helpful for you. Please leave your comment below, we can learn together. Thanks for being here, see you next week, bye!

Hola clara, saludos desde Venezuela, tendrás algún video para mejorar cortes deficientes en acero inoxidable?
Un abrazo ❤

[@ClaraChai]

Tengo un vídeo contando el pobre corte, creo que se puede conseguir algo allí.

[@medjoui7600]

Hi clara
Wich servo motor and servos drive is good
*Lichuan
*Inovance
Also incoder Wich one is good
*17 bit
*23bit

[@ClaraChai]

I use Yaskawa most.

[@afsalthavayil8754]

Hi Clara, iam using 1500 w fabric laser machine. The machine showing forward voltage alarm and stopped laser

[@ClaraChai]

I am not sure what is your problem, please tell me more.

[@medjoui7600]

clara i have questions about laser source:
we can cut by max power 100% of power for Long time 4 hours or laser source will damaged? just need to work for long time 4 hours need 85% of power to avoid damaged laser source ?
Thanks

[@ClaraChai]

My personal preference, won’t cut long time at 100% power.

[@medjoui7600]

@@ClaraChai thank you but how much is percentage of power is ok for long time of cutting.
For example if we have laser source 1500w and we want to cutting 10 mm thickness of mild steel and 4 hours of cutting .
How much of percentage of power is ok for this situation.
Thanks

[@afsalthavayil8754]

We are using 11 bar air compressor, that why have any issues?

[@ClaraChai]

16 bar please.
