  1. The voltage used by this product is AC 220V, 25A (depending on the power). Connect the power cord to the 220V power supply as shown in the figure.

2. Turn on the air switch of the equipment, and then turn on the emergency stop and the key to turn on the light. After the welding machine is powered on, the cooling fan and the chiller will run automatically (check whether the emergency stop and the key switch are turned on if they are not running). If the chiller is not filled with water, it will alarm. Pour distilled water into the chiller to the green normal area. If the alarm still occurs, please re-run the chiller to ensure that the working area on the chiller display is running.

3. When the chiller is running normally, wait for the chiller to control the water temperature at the set temperature before turning on the laser button, wait for more than 3S, there will be a "di" sound inside the device, then the enable button can be turned on, otherwise it will be invalid .

Laser indicator light: ALARM green ACTIVE red POWER green is normal.

4. Before using the optical fiber hand-held welding machine, it is necessary to inject protective gas (nitrogen or argon), and the equipment is equipped with a protective gas interface (PM8) at the rear, and adjust the gas size according to the welding product (not less than 0.15MPa).

5. Adjust the process parameters in the operating system of the device, click the air valve button to adjust the gas size, close the air valve button after adjusting the gas, and then click "Start" (at this time, the handheld gun has started to swing, and then there is a slight vibration, and the sound of the motor rotating).

6. After completing the above operations, the gun can be used normally.

How to use: clip the alligator clip to the object that needs to be soldered or a metal console that is connected to the object (make sure it is within 3M and not covered by paint). Then gently touch the nozzle of the gun on the welding position, press and hold the trigger button, stretch at a constant speed of about 45° in the front and rear, and release the trigger button to stop the light. (Wire feeding welding does not need to be stretched by itself, the wire will push the gun body to weld by itself)

System introduction and use

1 Operation overview and operation guide

The operation panel of SUP series is mainly composed of touch screen and control box. The touch operation interface mainly includes home page, process, setting, monitoring and other parts.

1.1 Touch screen operation main screen

①This interface can see the current process parameters and real-time alarm information.

②In the power-on state, the laser enables and indicates that the red light is ON.

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

④Welding 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 to control the spot welding time due to human beings.

1.2 Main screen of process operation

①The process interface includes the process parameters for debugging, click the box to modify, click OK after modification, and then save it in the shortcut process, click import when using (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, and the limiting relationship is: 10≤scanning speed/(scanning width*2)≤1000 If the limit is exceeded, 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 common scan speed: 300mm/S, width 2.5mm).

③The peak power should be less than or equal to the laser power on the parameter page (if the laser power is 1000W, the value should not be higher than 1000).

④ The duty cycle range is 0~100 (default 100, usually does not need to be changed).

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

Process reference (subject to the actual situation, the following is for reference only)

1.3 Setting the main screen of operation

Password 123456

①The laser power is the maximum power of the laser used.

②The default gas delay time is 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 with the retraction function.

⑤The maximum temperature alarm threshold is 70℃. When the value is set to 0, the temperature alarm will not be detected.

⑥ Scanning correction coefficient range is 0.01~4, coefficient target line width/measurement line width: generally 1.25.

⑦The laser center is offset by -3~3mm, if it is decreased, it will move to the left, and if it is increased, it will move to the right.

⑧ The alarm level signal is the default, and the shielding alarm can be directly changed to the corresponding level detection.

⑨ The duration of spot welding is the light-emitting time after the trigger is pulled, that is, even if the button is released, light will still be emitted according to the time-out (V3.3 version is the above function)

⑩The interval time of spot welding is the light stop time between two spot welding after pulling the trigger button (version V3.3 and above)

This interface displays the status of each detection signal and device information

Click Device Authorization to enter the authorized usage time interface, and after entering the password, the system can be authorized for the usage time.

Maintenance and maintenance of welding torches

1 How to maintain and replace the protective lens:

① The processing technology of laser welding requires regular maintenance of the lens. If the welding effect is found to be poor, check that the protective lens is dirty and replace the protective lens in time.

② Before operation, wash your hands with detergent and dry them, and then wipe your hands again with cotton glued with alcohol.

③ Remove the protective lens compartment cover screws in a relatively dust-free place, pull out the protective lens bracket, do a good job of protection, and check the protective lens (if the surface of the protective lens has obvious burns, it should be replaced directly.)

④ Then check the white power sealing ring under the protective lens. (If the power storage ring has any scratches or deformation, it cannot be used and must be replaced immediately.

⑤ Use a cotton ball dipped in alcohol to wipe the opening of the warehouse and the inside of the warehouse cover, quickly insert the protective mirror bracket into the protective mirror compartment, and tighten the screws.

2 Laser center adjustment method (oblique viewing angle)

When the red light cannot come out of the copper nozzle completely, it needs to be adjusted manually at this time to prevent the copper nozzle from being burned out.

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

①, as shown in the figure below, at this time, the red light cannot be seen completely coming out of the copper mouth

②. We need to remove the back cover, you can see four adjustment screws, adjust the center according to the video

③. Finally, to achieve this effect

④. The slight left and right deviation can be set by setting the laser center offset of the panel

Common exception handling

1. 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 device or the level of the alarm signal is set incorrectly.

2. The screen does not light up/click does not respond

① The screen does not light up, if the controller is powered on (the fan is running), check whether the four-core wire between the controller and the screen is connected correctly, and whether the 24V voltage of the 1st pin and the 4th pin is normal

②If the click fails during normal use, check whether the temperature of the whole machine is too high.

③Click can not input, check whether the four-core wire between the controller and the screen is connected correctly, and whether the 2nd and 3rd pins are normal, see 2.1.2 Controller LCD screen for details

④If there is no response when clicking on the newly installed device, it may be that the system version does not match. You can re-flash the program. Please ask our company for the SD card.

3. No light

①The 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

Usually, no light is emitted from the air and the wire is due to a laser fault or a wiring problem. If the air is not fed and the wire is not fed, it may be a problem with the preparation signal. For details, please refer to: 2.1.3 Controller Signal Interface 1

4. Sudden stop of light output during processing

The monitoring interface checks whether the safety lock and other alarms are normal, and also checks whether the temperature exceeds the temperature alarm threshold.

5. Red light bias

Cause Analysis:

1. The external interference source causes the swing motor to work normally, and the red light shifts slowly. Try to avoid sharing a power supply box with equipment such as argon arc welding machines that have a great impact on the power grid. The power supply of the welding head must be effectively grounded , at the same time, isolation transformers, magnetic rings, etc. can be used to eliminate part of the influence

2. The red light shift caused by the new QBH, lens or other replacement parts. When replacing some specific parts, the red light may be inconsistent with the previous one. It can be normalized by software setting or mechanical adjustment.

3. The signal line is broken (only the SUP15S welding head), check the five-core line, this situation is common in the normal processing that the light deviation cannot be adjusted suddenly and the motor has abnormal noise


1. Software settings (processing of cause 1/2)

Fine-tune by setting the laser center offset in the interface, followed by {1. Setting}-{2. Change the laser center offset value, the negative value is to the right, the positive value is to the left, the latest version can adjust the maximum value +3/-3 }-{3. Go back to the home page, turn off the red light indicator, and then turn on the red light indicator to refresh}. This solution can be fine-tuned left and right. If this method still cannot be adjusted, use mechanical adjustment.

2. Mechanical adjustment (cause 1/2 treatment) (please distinguish between 15S and 20S below)

Before performing mechanical adjustment, be sure to set the center offset to 0, see the three steps of software setting method

3. Disconnection (treatment of cause 3)

Check whether there is an open circuit in the air plug part of the five-core cable, you need to disassemble the air plug

Laser welding machine three-phase power wiring reference

Note: Two-phase or three-phase power depends on the power supply required by the laser and chiller, not the amount of wiring

Warning: Please do not move/install the machine without permission. Before preparing, please contact our after-sales service to provide the power supply definition of the whole machine, and the whole machine must be grounded! !
