Note: The ground wire of the switching power supply must be effectively grounded!

Optical input interface

SUP welding head is suitable for most industrial laser generators. Commonly used optical fiber connectors include IPG, Ruike, Chuangxin, Fibo, Tottenham, Jept, Kaplin, etc. The optics must be kept clean and all dust must be removed before use
When the fiber is inserted, the cutting head must be rotated 90 degrees to be horizontal, and then the fiber is used to prevent dust from falling into the interface.

installation method(Applets )

Shielding gas and water chiller interface

The water pipe and air pipe interface can be installed with hoses with an outer diameter of 6MM and an inner diameter of 4MM. The air path enters in the middle, and the two sides are Water inlet and outlet pipelines (regardless of the direction of inlet and outlet),As shown below:

sup-20s (5)

The cooling system is divided into the water circuit part of the welding head and the water circuit part of the optical fiber head, which are connected in series, as shown in the figure below:

Cleaning gun and control box connection interface

Three wires are used to connect the cleaning gun and the control box, including two motor power wires, five motor signal wires and six signal pins
2.51. The motor power / signal wires (two black) are directly connected to the motor part of the welding joint and can be removed (two options: 1. Open the motor cover and side plate of the hand-held welding gun; 2. Open the control box, both of which are plugs)
 2.52. The six core signal corner uses a detachable aerial plug

P1-1 Home,Light out

①In this interface, you can see the current process parameters (the process cannot be modified on this page) and real-time alarm information.

②In the power on state, the enable is ON by default, and the red light is LINE by default.
When the enable is turned off, "off" is displayed, and the enable signal will not be sent to the laser, which can be used to test the air outlet function
Turn off the red light indication, display "dot", and the motor stops swinging. At this time, the red light is a point for adjusting the center

③"Safety lock",When the "safety lock" of the gun body is opened, it is displayed as green "on" and can emit light normally. When it is closed, it is red "off" and cannot emit light.

P2 process interface

①The process interface contains the commissioning process parameters. Click the box (red) to modify them. After modification, click OK, and then save them in the shortcut process. When in use, click Import (modify save import).

②The scanning frequency range is 10-100Hz and the scanning width range is 0 ^ 300mm.(the most commonly used scanning speed is 50Hz and the width is 300mm. Please note that this width should match your focus.).

③ The peak power shall be less than or equal to the laser power on the parameter page (if the laser power is 1000W, this value shall not be higher than 1000).
④Duty cycle range: 0 ~ 100 (default: 100, usually no need to change).

⑤The pulse frequency range is recommended to be 5-5000Hz (the default is 2000, which usually does not need to be changed).

⑥Click the help button at the top right to get more explanations of relevant parameters.

⑦After modifying the parameters, you can check whether the import is successful on the home page.

⑧Refer to the process in the applet.

①The laser power is the power of the laser used, please fill in it correctly.

②The delay of switching gas is 200ms by default, and the range is 200ms-3000ms.

③When the light is turned on, it gradually increases from N1% of the process power to 100%; When the light is turned off, it gradually decreases from 100% of the process power to N2; (as shown in the figure below).

P3-2 Setting interface,parameter specification

④Generally, the switching optical power is 20% and the switching optical progressive time is 200ms.
⑤The maximum temperature alarm threshold is 65 ℃. When this value is set to 0, the temperature alarm will not be detected.

⑥Scan correction coefficient range is 0.01 ~ 4, coefficient target line width / measured line width: the default is 1.0.

⑦The laser center is offset by - 75 ~ 75mm, which decreases to the left and increases to the right. It should be used to adjust the red light center.
⑧The alarm level signal of air pressure / water cooler / laser is low by default. When using this alarm signal, if an external air pressure alarm is installed, it will be changed to high level, otherwise an abnormal alarm will appear, and other alarm signals are the same.

Laser trigger signal: this status changes from gray to green after pulling the trigger.
Laser / water cooler / air pressure alarm signal: monitor its set high and low levels.
The output signal is displayed in the middle of the page. When the signal is output, it is gray and green.

Equipment authorization: you can authorize the use time of the equipment. When the equipment is used for more than its set time, the authorization will be terminated.
Light out time: click "device authorization", enter " FFFFFFBB001" on the password page to start the timing, enter " FFFFFFBB000" to clear the data and stop the timing.

System version: three groups of numbers. The first group is the hardware version, the second group is the program version of MCU, and the third group is the touch screen version.

P4 Diagnosis interface

Click the "diagnosis" button to enter the diagnosis page.On this page,the laser will not emit light. You can independently output "PWM", "laser enable", "air valve enable" and "analog quantity" through "switch control". Compare the detected value with the theoretical value to judge whether the function of the control box is normal.


Maintenance and replacement methods of protective lenses:

①Before operation, wash your hands with detergent and dry them, and wipe your hands again with cotton pasted with alcohol.
②Remove the screws of the protective lens cover at a relatively dust-free place, pull out the protective lens support, protect it (covered with masking paper), and check the protective lens (if there is obvious burning point on the surface of the protective lens, it should be replaced directly.)
③Then check the white power storage sealing ring under the protective lens. (if the accumulator seal ring is scratched or deformed, it cannot be used and must be replaced immediately.
④Wipe the warehouse opening and the inside of the warehouse cover with a cotton ball dipped in alcohol, quickly insert the protective mirror support into the protective mirror warehouse, and lock the screws.

Common Exception Handling

Prompt laser / water cooler / air pressure alarm

①If the above alarm occurs without using the alarm signal, please change the alarm level.
②If 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 is not lit / there is no response when clicking

①the screen is not work. if the controller is powered on (the fan is running), check whether the four core wire between the controller and the screen is correctly wired and whether the 24V voltage of the first pin and the fourth pin is normal
②If the click fails during normal use, check whether the whole machine is caused by too high temperature.
③Click action cannot be entered,Check whether the four core wires between the controller and the screen are wired correctly, and whether the second pin and the third pin are normal,See 2.1.2 LCD of controller for details
④There is no response when clicking on the newly installed equipment. It may be that the system version does not match. Just brush the program again. For SD card, please ask our company

Sudden stop of light during processing

Check whether the trigger button and other alarms are normal on the monitoring interface
