4.Maintenance of handheld laser welding machine

4.1 How to maintain and replace protective lenses:

① 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.

② 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.

③ Before operation, wash your hands with detergent and dry them, then wipe your hands again with cotton with alcohol.

④ 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.

⑤ 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.)

⑥ 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.

⑦ 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.

4.2 Laser center adjustment method (oblique viewing angle)

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

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

③. Finally, this effect can be achieved

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

5、Common exception handling

5.1.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 equipment or the high and low levels of the alarm signal are set incorrectly.

5.2.The screen does not light up/click no response

①The 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

②If the click does not work during normal use, check whether the temperature of the whole machine is too high.

③Tap 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

④If 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.

5.3.No light

① 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

5.4.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.

5.5.Red light polarization

For details, please refer to 4.2 Laser Center Adjustment Method

Laser welding machine three-phase power wiring reference

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

Warning: Please do not move/install privately, please contact our after-sales company to provide the definition of power supply for the whole machine before preparing, and the whole machine must be grounded! !
