Winterizing Your Laser

The Impact of Cold on Your Laser

Lasers generate precise and controlled beams of light, which can be disrupted by temperature changes. If your laser is exposed to temperatures below 40° F (4° C), you risk damaging its components, particularly the water-cooled CO2 laser tubes. Freezing temperatures can cause the water inside these tubes to expand, leading to cracking tubes or even damaged chillers.

Weather Below Freezing

🛑 Stop 🛑 If your area is going to be experiencing temperatures near or below 10-15 degrees Fahrenheit (-12 to -9 Celsius) it is recommended that the chiller be filled fully with antifreeze. Using a blend when temperatures are that low can lead to damage of the laser tube or chiller

Steps to Winterize Your Laser For Storage

1. Monitor Temperature: Start by monitoring the temperature in the area where your laser is stored. Invest in a thermometer to keep an eye on the conditions regularly. If the temperature drops below 40° F, it's time to take action.
2. Drain the Water: First, turn OFF and unplug your machine. Since your laser utilizes a water chiller, the first step is to drain the water from the system. This is a critical step in preventing the water from freezing and causing damage to both the glass laser tube and the internal components of the chiller.

   Note: If you have not powered the machine ON since initially receiving it, please skip to Step 3.

3. Fill with Antifreeze: Instead of leaving the system empty, fill it with antifreeze blend. We recommend RV AntiFreeze. This will prevent any remaining water from freezing and protect the tubes from potential damage. Make sure to use the recommended type and follow our guidelines below for the proper amount.
   • MIRA 7: 1/4 gallon (1 quart) of distilled water, 1/4 gallon (1 quart) pink RV antifreeze or until full.
   • MIRA 9: 1/2 gallon of distilled water, 1/2 gallon of pink RV antifreeze or until full.
   • NOVA 10/ NOVA 14/ NOVA 16: 1/2 gallon of distilled water, 1/2 gallon of pink RV antifreeze or until full.
4. Cycle the System: Once you've drained the water and added the antifreeze blend, plug the machine in and turn it on. Allow the machine to sit idle and fully flush the antifreeze through the system. Power off the machine, once complete.

   Note: If you have just uncrated your machine, please clear the laser bed and cut the zip ties on the gantry.

5. Storage: Cover the machine with blankets or a car cover to protect it from any dust or debris.

   ⚠️Caution ⚠️ During extreme temperatures ensure that the exhaust duct hose is disconnected from the machine so that the outdoor environmental air does not connect directly to the machine. Cover with blankets as well.

Steps to Winterize Your Laser For Usage

1. Monitor Temperature: Start by monitoring the temperature in the area where your laser is stored. Invest in a thermometer to keep an eye on the conditions regularly. If the temperature drops below 40° F, it's time to take action.
2. Drain the Water: Since your laser utilizes a water chiller, the first step is to drain the water from the system. This is a critical step in preventing the water from freezing and causing damage to both the glass laser tube and the internal components of the chiller.

   • NOVA 10/ NOVA 14/ NOVA 16: 1/2 gallon of distilled water, 1/2 gallon of pink RV antifreeze or until full.
4. Using the Machine: Once you've drained the water and added the antifreeze blend, you can still use your laser. It's critical to maintain the proper conditions to avoid freezing and protect your laser. While you can still use your laser, there are some performance aspects to look out for, such as:
   • Decreased power output
   • Adjusting standard settings to compensate for the cooling mixture
5. Regular Maintenance: Even in the winter, don't neglect regular maintenance of your laser. Inspect the machine, clean the optics when necessary, and ensure that all components are functioning correctly. Regular maintenance is essential for the longevity and performance of your laser.

   ⚠️Caution ⚠️ Once the freezing temperatures are done in your region, it is highly recommended that you do a full flush and return to only pure distilled water. We have found that long term use of anything but pure distilled water can shorten the lifespan of a tube and can cause other odd engraving issues.

Winterizing your laser is a crucial step in ensuring its longevity and functionality during the colder months. The sensitivity of CO2 laser tubes to freezing temperatures makes it essential to take proactive measures. By monitoring the temperature, draining water, adding antifreeze, and storing your laser properly, you can protect your investment and avoid costly repairs.
