Five Operating Skills and Precautions of Fiber Laser Cutting Machine
Fiber laser is the core equipment of fiber laser cutting machine, which will have a great impact on the use of the whole machine after failure. One of the main reasons for the failure of the fiber laser power supply and module is the condensation inside the laser. The condensation inside the fiber laser has a lot to do with the poor operating habits of the customer using the fiber laser. In order to reduce the failure rate of the fiber laser and reduce the loss caused by the shutdown of the customer’s fiber laser cutting machine, Guangyuan Laser will help you. Please pay attention to the following matters when operating the fiber laser cutting machine:
Switching sequence of the fiber laser cutting machine (Strictly following the switching sequence can reduce the risk of condensation inside the fiber laser, thereby reducing the failure of the laser!!)
1.Starting sequence of fiber laser cutting machine
① Check whether there are items in the machine’s operating range that affect the safe operation of the machine
② Turn on the main power switch of the fiber laser machine and the control power switch of each branch
③ Turn on the voltage stabilizer and check whether the voltage stabilizer is operating normally
④ Turn on the power switch of the fiber laser and let the fiber laser with its own air conditioner or internal desuperheater run for more than 30 minutes
⑤ Turn on the air compressor when the fiber laser is powered on for 20 minutes and check whether the air compressor is operating normally
⑥ Open the air circuit control valve, turn on the refrigeration dryer, check whether the refrigeration dryer is operating normally, and check whether the air pressure is normal
⑦ According to the cutting needs, open the cutting auxiliary gas control valve and check whether the cutting auxiliary gas pressure is normal
⑧ Turn on the machine tool power switch, press the power button to start the machine tool control system, and the machine tool will return to the origin after the control system starts normally
⑨ Turn on the power switch and run the fiber laser for more than 30 minutes, then turn on the chiller and check whether the chiller is running normally
⑩ After the actual temperature of the high and low temperature water of the chiller reaches the set temperature ±1℃, the fiber laser will be high voltage, and check whether the fiber laser is operating normally
2.The order of fiber laser shutdown
① Turn off the exhaust fan or dust collector
② Turn off the high voltage of the fiber laser, return to the origin of the machine tool, and then turn off the control system as required. After the control system is shut down, press the power off button to turn off the power of the control system and turn off the main power switch of the machine tool.
③ Turn off the chiller
④ Turn off the refrigeration dryer and control valves for each gas path
⑤ Turn off the air compressor
⑥ Turn off the power switch of the fiber laser or keep the fiber laser in a charged state, and it can be quickly turned on the next day.
⑦ Turn off regulator
⑧ Turn off the power switch of each branch, turn off the main power switch of the fiber laser machine
3.Precautions for use during shutdown operation
If there is no cutting task or the rest time exceeds 1 hour during the startup process, it is recommended that the customer turn off the high voltage of the fiber laser, leave the power switch of the fiber laser, and turn off the chiller. When the product needs to be cut again, turn on the chiller to run, wait for the actual temperature of the high and low temperature water of the chiller to reach the set temperature ±1℃, and then apply high pressure on the fiber laser, and then cut the light.
Note: It should not happen that the power switch of the fiber laser is turned off while the chiller is still running!
4.Quick start operation skills
Don’t turn off the power switch of the fiber laser when it is turned off at night, so that the air conditioner or internal dehumidifier of the fiber laser is always working, and the power consumption is less. When the fiber laser is turned on the next day, there is no need to wait 30 minutes
5.ensure that the chassis is airtight
The case of the fiber laser adopts a closed design. Please pay attention to keep the case closed during use to prevent high temperature and high humidity outside air from entering the case. The following aspects should be paid attention to when checking the airtightness of the chassis:
1. Whether each cabinet door is closed; whether the lifting bolts on the top are tightened; whether the protective cover of the unused communication control interface at the rear of the chassis is covered, whether the used ones are fixed; whether the power cord inlet is sealed, etc.
2. If you need to open the cabinet door of the case for some reasons during use, you need to turn off the chiller before opening the cabinet door. After you can close the cabinet door, please follow the power-on sequence of the fiber laser, first turn on the power switch of the laser and run it for more than 60 minutes, then turn on the chiller, and wait until the actual temperature of the high and low temperature water of the chiller reaches the set temperature ±1℃, then the fiber laser high pressure.
I hope these sorted out can be helpful to you！
