Turn off the red light indicator and the motor stops swinging. Atthis time, the red light is a point for adjusting the center position. Thewelding mode is divided into continuous and spot welding. When spot welding isselected, the spot welding type needs to be set on the setting page. ③The safety lock is divided into gray and green.When the 5 and 6 pins of the signal interface 1 are short-circuited, thedisplay is green. At this time, the light can be emitted by controlling thesignal pin "welding head light switch 1, 2". ④Upper right cornerorange The button is a switch button,Click to switch to the cleaningmode selection interface. （2）Craft page
Scanning speed range: 2~6000mm/s; Peak power range: 1W～xW,x is the laser power on the setting page; Duty cycle range: 0～100%,the default setting is 100%, usually no need to change; Pulse frequency range: 5～100000Hz,5～5000Hzis recommended; Precautions： ①The process interface contains the processparameters for debugging. There are a total of 10 processes that can be savedin this version. ②The parameters of the craft page can bemodified, click the input box to modify, click OK after modification, and thensave, and click import when using it (modify-save-import). ③Some lasers cannot emit light with a power lowerthan 10%. When the peak power of the craft page is less than 10% of the maximumpower of the laser on the setting page, all output signals are normal, butlight may not be emitted. ④ The duty cycle is 100% by default, and usuallydoes not need to be changed. At this time, the pulse frequency does not work.If you need to use it, please adjust it according to actual needs. Example:300W peak power, 50% duty cycle, and 1000Hz pulse frequency. At this time, thelight emission period is 1mS, 0.5mS emits light at 300W, 0.5mS does not emitlight, and it cycles back and forth. At this time, the airblasts at the weldingplace and abnormal noise is normal. The actual situation is subject to thelaser parameters. ⑤ Click the "Help" button at the topright of the screen to get more related parameter explanations. ⑥More reference crafts can be viewed in thecraftsmanship of the WeChat applet. （3）Settingspage
Click "Settings" on the home page, andenter the password 123456 on the password input page of the pop-up window toenter the settings page. ①The laser power is the maximum power calibratedby the laser manufacturer used. Please fill in it correctly. ②The switch air delay defaults to 200ms, and therange is 0ms～3000ms. Example: Set the air-on delay to 1000ms, and theair-off delay to 500ms. The actual effect is that when the trigger is pressed,the breath lasts for 1000ms and then the light is emitted. Release the trigger,after the laser stops emitting light, continue to vent for 500ms and then stop venting. Reasonable setting of the switch gasdelay can well protect the molten pool from oxidation and prevent slag returnfrom damaging the lens. ③When the light is turned on, the process poweris gradually increased from N1 to 100%; when the light is turned off, it isgradually increased from 100% of the process power to N2; (as shown in thefigure below):
Generally, the preset switching optical power is20%, and the switching optical progressive time is 200ms; ④Wire feeding delay compensation is the wirefeeding advance time relative to the light signal. It can be used inconjunction with the withdrawal function, and it is not set by default; ⑤The maximum temperature alarm threshold is 65℃,when the value is set to 0, no temperature alarm will be detected; ⑥Scan correction coefficient = target linewidth/measurement line width, range 0.01～4. Generallyset to 1; ⑦Laser center offset -3～3mm,reduce it and move it to the left, increase it and move it to the right, it isused to adjust the red light center of the axis; ⑧The air pressure/water cooler/laser alarm levelsignal defaults to low level. When this alarm signal is used, the alarm levelhere needs to be set to be consistent with the alarm level of the externaldevice; ⑨Spot welding duration is the light emission timein each cycle in the spot welding mode, and the spot welding interval time isthe stop light time in each cycle in the spot welding mode; ⑩Click the "Language" box in the lowerleft corner to switch the interface language.

4.Cutting function This systemdoes not have a professional cutting mode. Based on the actual power of thelaser, the welding mode can be used for thin plate cutting. When you needto use the cutting function, please replace the cutting copper nozzle and setthe scan width to 0mm. 5.Maintenance How tomaintain and replace protective lenses: ① Beforeoperation, please clean your hands and wipe them dry, and then wipe your handsagain with cotton dipped in alcohol. ② Remove thescrews of the protective lens compartment cover in a relatively dust-freeplace, pull out the protective lens bracket, and protect it (covered by maskingpaper). Check the protective lens. If there is obvious burning on the surfaceof the protective lens, replace it directly. ③ Then checkthe white accumulating sealing ring under the protective lens. (If there is anyscratch or deformation of the accumulating seal ring, it cannot be used andmust be replaced immediately. ④ Wipe thecompartment opening and the inside of the compartment cover with a cotton balldipped in alcohol, quickly insert the protective lens holder into theprotective lens compartment, and tighten the screws. 5. Commonexception handling 5.1 Prompt laser/water cooler/air pressure alarm ① If the abovealarm occurs without using the alarm signal, please change the alarm level onthe screen setting page. ② If the abovealarm occurs when the alarm signal is used, check whether the alarm of thecorresponding equipment or the high and low levels of the alarm signal are setincorrectly. 5.2 The screen doesn't light up/click no response ① If thescreen is not on, make sure that the controller is powered on, and checkwhether the four-core wire between the controller and the screen is correctlywired, and whether the 24V voltage of pin 1 and pin 4 is normal. ② If the clickdoes not work during normal use, check whether the temperature of the wholemachine is too high. ③ Tap Cannotinput, check whether the four-core wire between the controller and the screenis correctly wired, and whether the second and third pins are normal. Fordetails, see 2.1.2 on the display of the controller. ④ There is noresponse when clicking on the newly installed device. It may be that the systemversion does not match, just use the SD card to re-swipe the program. Pleaseconsult our company for the specific version. 5.3 No light ① Checkwhether there is an alarm prompt on the homepage and whether the laser enableis ON; ② Checkwhether the trigger signal and safety lock signal on the monitoring page aredisplayed in green when welding; ③ Checkwhether the PWM, laser enable, and analog output on the monitoring page arenormal during welding. If the abovestatus is normal, please check whether the laser has abnormal alarm. Example: Theair is fed and the wire is fed but the light is not emitted, which is becausethe laser is faulty or the laser wiring is wrong. If neither the air is ventednor the wire is fed, the input signal may be missing. For details, see: 2.1.3Controller signal interface 1. 5.4 The light suddenly stops during processing Check whetherthe monitoring interface is securely locked and other alarms are normal.
Appendix Three-phasepower wiring reference for laser welding machine: Note:Two-phase or three-phase power depends on the power supply required by thelaser and chiller, not the amount of wiring harness.
