Maintaining Laser Cutters During High-Temperature Summer

What are the key considerations for laser cutters during summer?

1. In summer, some regions will have the plum rain season, with increased rainfall, and there may even be floods. How to prevent such situations? First of all, we must operate in accordance with the methods of professionals, which can avoid the worst-case scenarios and minimize losses. In addition, it is essential to conduct safety training, putting life safety first. In summer with volatile weather, the following content about the protection and maintenance of laser machines is briefly sorted out to help you strengthen the protection knowledge of laser cutting machines in summer.

Do a good job in prevention.

1. Fire prevention

As the ambient temperature rises, the probability of various items being flammable increases. Pay attention to sparks generated during the cutting process and keep the surrounding environment clean to prevent fire risks. Place dry powder fire extinguishing devices nearby and conduct fire drills. In case of an accident, immediately cut off the power and gas supply of the equipment, then quickly pick up the fire extinguisher, pull out the safety pin, hold the nozzle tightly against the root of the fire, press the handle, and sweep to extinguish the fire. After extinguishing the fire, clean the equipment dust, pay special attention to protecting the optical path from contamination. If needed, you can contact our after-sales service for help.

2. Pay attention to check whether the lubricating oil of the equipment's moving parts overflows. Oil is flammable, and even flame-retardant items will become flammable if stained with oil, such as organ covers, dust, etc. If there is excess lubricating oil overflow, pay attention to daily cleaning of oil stains near the cutting head and on the organ cover. And according to the lubrication situation, set the time of the oiling device reasonably. If you have any questions, contact our after-sales service in time.Accumulation of metal dust can cause dust explosion accidents in specific environments. It is necessary to arrange for dust cleaning of the equipment every shift.

1) Clean the surrounding environment and do not pile up flammable and explosive foreign objects around to avoid fire caused by spark splashing during operation.

2) Smoking is prohibited in the cutting area, especially near oxygen cylinders.

3) Accumulation of metal dust can cause dust explosion in specific environments, so it is recommended to do a good job in dust cleaning.

4) Install dry powder fire extinguisher devices near the equipment and conduct safety training such as fire drill.

3. Condensation prevention

1) To prevent condensation in the laser optical path in summer, it is recommended to adjust the cooling water temperature reasonably.

Chiller water temperature settings when the ambient temperature in summer is above 30°C:

Low-temperature water: 27°C

High-temperature water: 30°C

For air-conditioned rooms, adjust the temperature of the air-conditioned room to 23-25°C for dehumidification, keeping the humidity below 50%.

Low-temperature water: 25°C

High-temperature water: 30°C

2) It is strictly forbidden to place obstacles around the chiller, as it will affect the heat dissipation of the chiller. It is recommended to clean the filters and radiators of air compressors, water tanks, air conditioners, freeze dryers, etc. every week to enable them to dissipate heat better and resist high temperatures.

4. Flood prevention

1) First of all, know the weather conditions in advance. If it is unavoidable, the machine can be transferred in advance, and protection work for important components such as the cutting head, laser, and electrical cabinet should be done to prevent them from being soaked by rainwater. In addition, in case of rain, protection can be done through the following operations:

2) Prepare an appropriate amount of waterproof tools in the factory in advance. When rainwater may flood into the workshop, immediately block the relevant entrances with straw bags, soil bags or quick-setting cement, and clean the drainage ditches.

3) When a heavy rain comes, the power supply of the equipment should be cut off in time to prevent short circuits and damage to components.

4) Fix the equipment properly to prevent it from being washed away and causing secondary damage to the factory building and other facilities.

5. Lightning strike prevention

1) Stop the operation of the laser cutting machine in thunderstorm weather and cut off the power supply.

2) If work is required in thunderstorm weather, ensure that the factory grounding meets national standards. It is strictly forbidden to use iron rods or steel beams instead of grounding.

Correct emergency operations can effectively reduce losses caused by severe weather disasters. To avoid major losses to your production, High Energy Laser reminds all customers and friends: For the high-temperature and high-humidity summer, be sure to take various preventive and response measures.

Summer maintenance of lasers

1. Maintenance of chillers

1) Distilled water or deionized water must be used.

2) It is recommended to replace it every 30 days in summer.

2. Maintenance of the processing head

When the season changes or the temperature changes greatly, if the laser has abnormal processing phenomena, in addition to the laser itself, it is also necessary to check whether condensation occurs in the internal environment of the processing head. Condensation in the processing head will cause serious damage to the optical lens, directly affect the cutting effect, and then affect the fiber head and fiber core diameter, etc.

1) If the cooling temperature is lower than the ambient dew point temperature, it will cause condensation on the inner wall of the processing head and the optical lens. Ensure that the high-temperature water temperature is set above 30°C.

2) In high-temperature summer, it is recommended to change the water every 30 days or so to prevent waterway blockage.

3) Ensure the cleanliness of the cutting gas. Before use, it is necessary to check whether the gas and pipeline have residues, water vapor, oil and other pollutants. Impurities will also condense into water vapor due to temperature differences.

Correct emergency operations can effectively reduce losses caused by severe weather disasters. To avoid major losses to customers' production, SL LASER reminds everyone: In the high-temperature and high-humidity summer, in case of emergency, do not panic, and calmly operate and respond according to the correct methods. The steps for protection and maintenance work vary for different lasers. If you are using a machine that is not from SL LASER and encounter an emergency, you are also welcome to contact us, and we will provide professional knowledge to solve your troubles.
