Control panel and operation guide (the following is V3.3 version)

Operation summary and operation guide
The operation panel of SUP series is mainly composed of touch screen and control box. Touch the main page, process, setting, and monitoring of the operation interface.

Touch screen operation main screen

In this interface, you can see the current process parameters and instant alarm information.
The laser is enabled and the indicator red light is ON when it is turned on.
The safety lock is usually gray, and when the welding head touches the workpiece, it becomes green and can be processed.
Welding mode selection, the default is continuous. When it is set to spot welding, it can emit light intermittently for spot welding operation, which is convenient for controlling the spot welding time due to human error. This function needs to be set as needed (V3.3 version is the above function)

Process operation main screen

The process interface contains the process parameters for debugging, which can be modified by clicking the box. After the modification is completed, click OK, and then save it in the shortcut process. When using it, click Import (Modify-Save-Import).
The scanning speed range is 2-6000mm/S, and the scanning width range is 0^5mm. The scanning speed is limited by the scanning width. The limitation relationship is: 10≤scanning speed/(scanning width*2) ≤1000 If it exceeds the limit, it will automatically become the limit value. When the scan width is set to 0, it will not scan (ie point light source) (the most commonly used scan speed: 300mm/S, width 2.5mm).
The peak power must be less than or equal to the laser power on the parameter page (for example, the laser power is 1000W, then the value is not higher than
1000).
Duty ratio range 0~100 (default 100, usually do not need to change).
The recommended pulse frequency range is 5-5000Hz (the default is 2000, usually it does not need to be changed).

The laser power is the maximum power of the laser used.
The switch air delay defaults to 200ms, and the range is 200ms-3000ms.
When the light is turned on, it will gradually increase from N1% of the process power to 100%; when the light is turned off, it will gradually increase from 100% of the process power.
To N2; (as shown in the figure below).
Wire feeding delay compensation is the wire feeding advance time relative to the light signal, which can be used in conjunction with the withdrawal function.
The maximum temperature alarm threshold is 70℃. When the value is set to 0, the temperature alarm will not be detected.
Scan correction coefficient range 0.01~4, coefficient target line width/measurement line width: generally 1.25.
Laser center offset -3~3mm, reduce it and move it to the left, increase it and move it to the right.
The alarm level signal is the default, and the shielded alarm can be directly changed to the corresponding level detection.
Spot welding duration is the light emitting time after pulling the trigger, that is, even if the button is released, the light will still be emitted according to the time spent (V3.3 version is the above function)
Spot welding interval time is the stop light time between two spot welding after pulling the trigger button (V3.3 version and above function)

Maintain

How to maintain and replace protective lenses:

The processing characteristics of laser welding require regular maintenance of the lens. If the welding effect is found to be poor, check that the protective lens is dirty, and the protective lens should be replaced in time.
The cleaning technology of the lens is extremely important. If it is not cleaned well, the performance of the lens will be reduced, and the lens will be damaged if it is not cleaned. Therefore, you must be very careful when cleaning the lenses.
Before operation, wash your hands with detergent and dry them, then wipe your hands again with cotton with alcohol.
Before cleaning, prepare a balloon (leather tiger), a set of clocks, dust-proof non-stick tape, anhydrous absorbent cotton (fine cotton), more than 99% industrial alcohol, finger cots or rubber gloves, and lens cleaning paper.
Remove the screws of the protective lens compartment cover in a relatively dust-free place, pull out the protective lens holder, and check the protective lens. If the protective lens is contaminated, it must be wiped clean with lens cleaning paper dipped in absolute alcohol.(If there are obvious burning spots on the surface of the protective lens, it should be replaced directly.)
Then check the white accumulating sealing ring under the protective lens. (If there is any scratch or deformation of the accumulating sealing ring
They cannot be used and must be replaced immediately.
Use a cotton ball dipped in alcohol to wipe the mouth of the compartment and the inside of the compartment cover, quickly insert the protective lens holder into the protective lens compartment, and tighten the screw.

Laser center adjustment method (oblique viewing angle)
（Click to browse video)（Applets）
When the red light cannot completely come out of the copper nozzle, manual adjustment is required at this time to prevent the copper nozzle from being burnt Please note: When using for the first time, when the red light cannot come out from the copper mouth, be sure not to emit light

As shown in the figure below, no red light can be seen completely coming out of the copper mouth at this time
We need to remove the back cover, you can see four adjustment screws, adjust the center according to the video
Finally, this effect can be achieved
The slight left-right deviation can be set by setting the panel laser center offset

Common exception handling

Prompt laser/water cooler/air pressure alarm

If the above alarm occurs without using the alarm signal, please change the alarm level.
If the above alarm occurs when the alarm signal is used, check whether the alarm of the corresponding equipment or the high and low levels of the alarm signal are set incorrectly.

The screen does not light up/click no response

The screen does not light up. If the controller is powered on (the fan is rotating), check whether the four-core wire between the controller and the screen is correctly wired, and whether the 24V voltage of the 1st pin and the 4th pin is normal
If the click does not work during normal use, check whether the temperature of the whole machine is too high.
Tap to fail to input, check whether the four-core wire between the controller and the screen is connected correctly, and whether the second and third pins are normal. For details, please refer to 2.1.2 LCD screen terminal of the controller
If the newly installed equipment clicks and there is no response, it may be that the system version does not match, just re-flash the program. Please contact our company for the SD card.

No light

The monitoring interface can exclude other alarms. When the welding head touches the workpiece to be processed, the safety lock is displayed in green, and it can be processed at this time. If it is gray, check whether the connection of the safety lock is normal.
That is, check whether all the ready signals are normal
Normally, the failure of the air outlet and the wire to emit light is caused by the laser failure or the wiring problem. If the air does not emit and the wire is not fed, it may be a signal problem. For details, please refer to: 2.1.3 Controller signal interface 1

Suddenly stop emitting light during processing
The monitoring interface checks whether the safety lock and other alarms are normal, and at the same time checks whether the temperature exceeds the temperature alarm threshold.
