What are the techniques for preventing laser cutting machines from freezing in winter?
The Great Cold solar term is approaching, signaling the onset of the year's coldest period with temperatures already dropping below freezing in some regions. Just as people need to bundle up, laser cutting machines require frost protection to prevent damage from freezing during the harsh winter.

The fundamental principle of frost protection for laser cutting machines is to prevent the coolant from reaching its freezing point. Let's outline several specific methods one by one.
Method One: Do not shut off the water chiller when the laser cutting machine is idle.
Ensure the power supply remains active (avoiding power outages) when the machine is not in use. Keep the water chiller running to maintain continuous coolant circulation. Simultaneously, adjust the standard temperature setting to approximately 10°C (50°F). This prevents the coolant from reaching freezing point, thereby protecting the laser cutting machine from damage.
Method Two: Drain Coolant from the Laser Cutter
Drain the coolant from all components of the laser cutter through its drain port. Inject purified gas to ensure no coolant remains in the entire water-circulation cooling system. This also protects the laser cutter from damage caused by low temperatures.
Method Three: Replace the Coolant in the Laser Cutting Machine
Just as cars on winter roads switch to antifreeze, equipment can also use automotive antifreeze. However, always choose a reputable brand. Impurities in low-quality antifreeze can adhere to pipes in components like the laser, causing damage. Antifreeze should not replace purified water or deionized water for year-round use. Replace it promptly after winter ends.
The above methods play a crucial role in ensuring the laser cutting machine operates normally and safely during winter. The first two methods are recommended. Method One saves time and effort but may risk damage to the laser cutting machine in case of sudden power outages. Method Two is labor-intensive and resource-consuming but offers relatively greater safety and effectiveness compared to the other two methods.
Friendly Reminder:
The following year, before commencing laser cutting operations, start the machinery and conduct a comprehensive inspection. Check all oils and coolants for shortages or depletion, promptly replenishing or replacing them as needed. Investigate any signs of deterioration to determine the cause. This will significantly enhance the operational efficiency of the laser cutting machine.
