Routine maintenance and repair can make the handheld laser welding machine work better, but also can make the laser welding equipment to use longer years, to create more value for us.

Today I come to you to talk about the daily maintenance and maintenance of laser welding machine.

1. Environmental requirements and cleaning

① The machine must be installed in a ventilated and dry environment, the ambient temperature does not exceed 35 ℃, the equipment is well ventilated around the wall with more than 50 centimeters of space, especially behind the water tank outlet should be to ensure good ventilation.

② Because the main components of the laser welding machine for the optical components, should always keep the external environment hygiene, focus on cleaning as follows:

A: equipment surrounding environment

B: optical dust cover

2. How to maintain the water cooler in the approaching winter

(1) Before starting the machine, please make sure that the water level in the tank reaches the specified position.

(2) Regularly replace the water in the water tank once every 30 days to ensure the cleanliness of the concentrator cavity, otherwise it will affect the laser energy, which needs to be injected into the water for pure water. Pure water.

(3) Regularly (about 15 days) to clean the dust net, cleaning method for removing the filter directly compressed air spray wash or rinse with tap water.

(4) The filter element is found to become yellow or black when you want to replace the new one in time, the longest replacement time is 2 months.

(5) the advent of winter in order to prevent icing, you can make the chiller has been kept above 0 degrees Celsius, such as can not meet the conditions, you can always keep the chiller on the state, so that the water in the pipeline to maintain the flow of state, to prevent icing.

(6) During the holidays, the chiller is in a state of shutdown, or due to faults caused by a long period of downtime, you can try to drain the chiller tank and piping water.

(7) Under normal circumstances, the chiller temperature range is set at 27-28 degrees, but because of the weather is likely to be a low-temperature alarm, the correct approach is to open the chiller first, so that the chiller is energized for a period of time, or you can use the heater properly with the right amount of boiled water, in which case the machine warming up quite a bit more quickly, or will be placed in the chiller place temperature must be maintained at more than 12 degrees.

(8) According to the actual situation of the chiller, can be appropriate to add antifreeze. (Antifreeze is mostly corrosive, in the case of meeting the antifreeze performance, the lower the concentration the better.)

3. Simple troubleshooting

① Close the cabinet air switch and turn on the key switch without response;

A:Measure whether there is voltage input to the main power line;

B:Check whether the emergency stop switch is pressed (just rotate to the right to pop up).

② When the power supply is started normally, the right side of the screen shows undervoltage

A:Check whether the water circuit is normal (whether the water tank is alarmed and whether there is running water);

B: power off to see if the electrode chucks at both ends of the xenon lamp is loose;

③ machine work process laser energy suddenly become weak

A:Check whether the protective lens under the laser focusing mirror is damaged;

B:Check whether the water temperature in the water tank is high;

C:Open the optical path dust cover, check the laser cavity for condensation (dry the water droplets with a paper towel) at the same time to see if there are water droplets on the two end faces of the laser bar (wipe with a clean cotton swab gently in a circle);

D: water tank work, observe the laser rod at both ends whether there is water seepage (such as there is a shutdown) may be the seal has been damaged, at this time, please contact us to give guidance on the phone.

5. Laser welding machine overall maintenance and maintenance

Laser welding machine is mainly composed of electronic devices, precision instruments, optical devices, the use of the environment and daily maintenance have high requirements.

(1) When the equipment is not working, the welding machine and computer power supply should be cut off.

(2) When the equipment is not working, the field mirror lens cover to prevent dust contamination of the optical lens.

(3) equipment work circuit is a high-voltage state, non-professionals, do not overhaul the power on to avoid electric shock accidents.

(4) Any failure of the equipment should immediately cut off the power supply.

(5) equipment for a long time, the dust in the air will be adsorbed on the surface of the lower end of the focusing mirror, the lesser will reduce the power of the laser, affecting the welding effect: the heavier caused by the optics of the lens to absorb heat over-temperature so that the crack. When the welding effect is not good, you should carefully check whether the surface of the focusing mirror is contaminated.

If the surface of the focusing mirror is contaminated, the focusing mirror should be removed to clean its lower surface.

Remove the focusing mirror should be especially careful, pay attention not to touch or fall: at the same time, do not touch the focusing mirror with your hands or other objects.

Cleaning method is anhydrous ethanol (analytically pure) and ether (analytically pure) mixed at a ratio of 3:1, with a long fiber swabs or lens paper into the mixture, gently scrub the lower surface of the focusing mirror, wipe each side, must be replaced once the swabs or lens paper.

(6) In the welding machine work process, do not move the welding machine, so as not to damage the machine.

(7) Do not cover the welding machine on the pile or put other items, so as not to affect the cooling effect of the machine.
