Installation and use instructions

installation and use requirements

1. Ensure that the equipment is installed and used steadily to avoid damage caused by falling or tipping.
2. Ensure good ventilation and keep at least 60cm of space around the equipment for heat dissipation to avoid affecting performance due to poor heat dissipation.
3. Check the protective lens before use. If it is dirty, please clean in time. (Use a cotton swab dipped in special cleaning solution and scrub the protective lens counterclockwise from the center to the edge.) When cleaning, pay attention to lens protection and avoid scratches.
4. The hand-held welding head should be handled with care.

0peration precautions

1. Please refer to the main technical parameter table for the operating voltage. If not, please use a transformer.

2. In the cold environment, please ensure that the cooling medium is not frozen, to avoid the abnormality of the cooling system.

3. Protect it from rain and water when outdoor use.

4. When the temperature of the water chiller is lower than 22°C, the laser low temperature alarm will occur, and it needs to be preheated.
   When the temperature reaches 22°C, please turn it off and then turn it on again to clear the alarm.

5. Avoid installation and use in places with a lot of dust, oil mist and high-frequency interference sources.

Installation steps

1. Connect the laser welding machine host power cord.
2. Connect protective gas.
3. Connect the control cable between the laser welding machine host and wire feeder.
4. Connect the wire guiding tube.
5. Install the welding wire.
   Put the wire feed reel into the reel shaft. Align the small hole of the wire feed reel with the positioning pin of the reel shaft. Open the pressure adjustment knob outward,open the wire pressing wheel, insert the welding wire from the right side of the wire feed nozzle, and pass through the two wire pressing wheels. Insert the welding wire into the wire guiding tube and ensure that the welding wire is exposed from the wire guiding nozzle of the hand-held welding head. Fasten the wire pressing wheels at both ends. Adjust the pressure adjustment knob to ensure the wire feeding force.
   For detailed steps, please watch the video tutorial.
   

Operation Process

1. Start-up and preparation
   1 Check the water level of the chiller to ensure that the water level is within the standard area.
   2 Connect the power cord (pay attention to grounding).
   3 Turn on the main power, turn off the emergency stop, and turn on the laser switch.
   4 Open the protective gas and adjust the air pressure to 2:: 0 .15MPa.
   5 Turn on the wire feeder and set the wire feeding parameters.
   6 Clamp the safety clip to the welding workpiece or welding table.
   7 Turn on the enable. Take out the hand-held welding head gun and ensure that the bending radius of the integrated cable shall not be less than 200mm.

2. Manual focus is required when using the device for the first time.
   1 Loosen the fixing screws of the front and rear telescopic tubes of the handheld welding head, and insert all the telescopic tubes into the gun head until they cannot be inserted. Adjust the laser power to 30°/o.
   2 Clamp the safety clip on the handheld welding head and stop the wire feeder. Trigger the laser against the iron plate or stainless-steel plate, find the point with the largest laser energy from far to near, where the sparks are scattered, which is the focus of the laser.
   3 After finding the focus, pull the telescopic tube out to make the distance between the focus and the telescopic tube about 4mm, and lock the telescopic tube.

3. Adjust the wire feed nozzle to fit the copper nozzle so that the welding wire is in the middle of the copper nozzle.

4. Remove the safety clip and clamp it to the welding workpiece or welding table.

5. Set the welding parameters according to the requirements of the workpiece to be welded.

6. When the handheld welding head touches the surface of the workpiece, press the switch button of the hand held welding head to start welding.

7. Shutdown: Turn off the wire feeder, turn off the enable, the laser switch, press the emergency stop, and shut the main power supply.
   For detailed steps, please watch the video tutorial.

Laser Welding Controller Setting Instructions

After the power is turned on, the welding control screen of the laser welding controller will enter the main operation interface.

Main operation interface

1. The current process parameters can be seen on this interface.
2. When the power is turned on, the laser enable is ON, and the red light indicates LINE.
3. The safety lock is gray by default, and it turns green when the welding head touches the workpiece.
4. The welding mode defaults to continuous. When it is set to spot welding, the laser can be intermittently emitted for spot welding operations.

Technology interface

The technology interface contains the set process parameters, which can be modified as needed. They can be saved in the quick process and clicked to import when using (modify-save-import).

1. The most commonly used scanning speed is 300mm/s and the width is 2.5mm. The scanning speed is limited by the scanning width:
   10 scanning speed/(scanning width*2) s1000. 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 laser).

2. The peak power should be less than or equal to the laser power (if the laser power is 1 OOOW, the value should not be higher than 1000).

3. Process reference value (subject to actual conditions).

Maintenance

Note: In order to avoid personal injury and man-made damage, the maintenance of the handheld laser welding machine must be carried out by professionals.

Handheld welding head

1. Daily inspection: Check the protective lens. If there is foreign matter, use a special dust-free cotton swab dipped in industrial alcohol to clean and wipe it. If there is coating damage or lens damage, please replace the protective lens in time to avoid burning other optical lenses.

2. Regular inspection: When the machine is used or not used for some time, first check the laser module, and make sure that each optical component is free from dust pollution, mildew, and other
   abnormal phenomena before turning it on.

3. Observing the light spot: The operator should often check the laser output light spot with black image paper. Once the spot is found to be uneven or skewed, it should be repaired in time.

Water chiller

1. The dust on the condenser and the dust filter needs to be cleaned regularly.
2. When the machine is transported or not used for a long time, the coolant should be drained.
3. When the temperature is lower than 2°C, please check and ensure that the chiller is working properly before using the machine to avoid damaging the laser tube, output head, and water chiller due to the solidification of the coolant.
4. The coolant must be replaced in the following cases
5. The filter element has been replaced.
6.  After 3 months of use.
7. Use again after long-term non-use.

Transportation and storage

1. Before moving the equipment, please remove the power cord and drain the coolant inside the system. Do not move or transport it with liquid inside.
2. When transporting or handling the equipment, please do not bump it up and down or excessively tilt it (not more than 45°) to avoid bumping, impacting and overturning.
3. During storage, drain the water in the water tank through the sewage outlet, and at the same time loosen the drain plug under the water pump to drain the remaining water in the water pump, and place it in a cool and ventilated place.
