How to Protect Laser Cutting Machine from Freezing in Winter

Anti-freezing measures for your laser cutting machine

I. Adding antifreeze

Adding a suitable amount of antifreeze to the cooling water is an effective method to prevent freezing. Choose high-quality antifreeze, such as the standard US Koolance antifreeze, and follow the recommended mixing ratios. Here are some commonly used mixing ratios:

For ambient temperatures of 2-5°C, mix antifreeze and water at a ratio of 2:8 to 2:5.

For ambient temperatures of 12-15°C, mix antifreeze and water at a ratio of 3:7.

For ambient temperatures of 22-25°C, mix antifreeze and water at a ratio of 4:6.

For ambient temperatures of 32-35°C, mix antifreeze and water at a ratio of 5:5.

For ambient temperatures of 42-45°C, mix antifreeze and water at a ratio of 6:4.

Remember to shut off the power of the water cooler and drain the water from the tank before adding antifreeze.

II. Draining water pipes and output heads

When the ambient temperature drops below zero and the laser equipment is not in use, it is essential to empty the water inside the equipment to prevent freezing. Follow these steps:

Disconnect the water pipes at the rear of the laser equipment and open the ball valve to let the water flow out.

Use compressed air or nitrogen at 0.5MPA (5 kg) to blow into the main circuit's drain port for 3 minutes, pause for 1 minute, and repeat the process 4-5 times while observing any changes in water mist at the drain port. When there is no water mist at the drain port, it indicates the completion of the draining process. Finally, close the ball valve of the laser equipment and seal the water pipe connections with plugs or tape to prevent dust accumulation.

Remove the Φ6 inlet and outlet water pipes from the QBH output head.

Blow compressed air or nitrogen at 0.2MPA (2 kg) into one Φ6 fine water pipe while keeping the other Φ6 fine water pipe downward until there is no water mist in the downward pipe. Then seal the inlet and outlet water pipes with tape. While performing this operation, take care to prevent water droplets from dripping onto the laser head and other circuits.

Additional measures to protect the laser cutting machine from freezing

Maintain an appropriate room temperature

Keep the temperature of the room where the laser equipment is located within an optimal range, avoiding excessively low ambient temperatures. If necessary, use heaters, heat lamps, or heating elements to provide additional warmth.

Use insulation materials

Utilize insulation materials such as insulation cotton or insulation boards around the laser equipment to prevent direct exposure to cold air. This will help maintain a stable temperature and reduce the risk of freezing.

Regular inspection and maintenance

Periodically inspect the cooling system of the laser equipment to ensure proper functioning of components such as water pumps, coolers, and pipes, with no leaks or blockages. Additionally, pay attention to cleaning the surrounding area to prevent the accumulation of dust and debris.

Control ambient humidity

Condensation can cause damage to laser equipment. Therefore, it is important to control the humidity of the surrounding environment and prevent moisture from accumulating on the equipment. You can use dehumidifiers or ensure adequate ventilation to regulate humidity levels.

Before implementing these protective measures, carefully read the manufacturer's guidelines for your laser equipment and consult professionals for advice. Different laser devices may have specific requirements and recommendations, so make adjustments based on your specific circumstances.

Protecting laser cutting machine from freezing is crucial to maintaining its stable operation and prolonging its lifespan. By implementing appropriate anti-freezing measures and additional protective methods, you can confidently use your laser cutting machine during the cold winter months, avoiding damage and costly downtime caused by freezing.

Remember, maintaining and protecting your laser cutting machine is essential for continuous production. Investing time and effort in equipment protection will yield long-term returns.
