    Note: The COM terminal of ±15V switching power supply and the -V (0V) terminal of +24V switching power supply must be connected to GND and fully connected to the workpiece at the same time. The shell of the switching power supply must be connected to the ground, otherwise, a safety ground lock alarm may occur, and no light will be emitted.

    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:

    Welding gun and control box connection interface

    The welding gun and the control box use three wires to connect, including: two-core motor power line, five-core motor signal line, three-core safety ground lock and trigger button line

    The motor power/signal wires (two black wires) are directly connected to the motor part of the welding head and can be disassembled (two options are available:1. Open the motor cover and side plate of the handheld welding gun 2. Open the control box All are plugs)
    Safely lock and trigger button three-core wire used Removable aviation plug:Safely lock and button wires, of which 1 is blue, 2 is black, and 3 is brown (connected to pin 6/7/8 of signal interface 1, see the wiring definition of the control box above for details)

    Wire feeder installation

    The two-core aerial plug at the tail of the wire feeder is connected to pin 5/6 of signal interface 2. Refer to the following for the specific installation method

    ①In this interface, you can see the current process parameters and instant alarm information.

    ②The laser is enabled and the indicator red light is ON when it is turned on.

    ③The safety lock is usually gray, and when the welding head touches the workpiece, it becomes green and can be processed.

    ④ 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)

    ①The 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).
    ②The 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).
    ③The 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
    ④Duty ratio range 0~100 (default 100, usually do not need to change).
    ⑤The recommended pulse frequency range is 5-5000Hz (the default is 2000, usually it does not need to be changed).

    ①The laser power is the maximum power of the laser used.
    ②The switch air delay defaults to 200ms, and the range is 200ms-3000ms.
    ③When 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).

    ④Wire feeding delay compensation is the wire feeding advance time relative to the light signal, which can be used in conjunction with the withdrawal function.

    ⑤The maximum temperature alarm threshold is 70℃. When the value is set to 0, the temperature alarm will not be detected.
    ⑥Scan correction coefficient range 0.01~4, coefficient target line width/measurement line width: generally 1.25.
    ⑦Laser center offset -3~3mm, reduce it and move it to the left, increase it and move it to the right.
    ⑧The alarm level signal is the default, and the shielded alarm can be directly changed to the corresponding level detection.
    ⑨Spot 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)
    ⑩Spot welding interval time is the stop light time between two spot welding after pulling the trigger button (V3.3 version and above function)
