[@BigMAX525]

You can add more water in the bucket and it will be cool for longer time.

[@TheGarageEngineer]

Great idea. Thank you.

[@brunowinacio]

What amount of water do you recommend?

[@Ricks2Cents]

I will be adding Air Assist me mine soon.

[@TheGarageEngineer]

Game changer.

[@Ricks2Cents]

@@TheGarageEngineer I have air assist on All My Diode Lasers, the k40 is my only C02 Laser.

[@ChrissRollex]

How are you cooling your laser tube? Are you using just deionized water, or have you added anything else instead?

[@TheGarageEngineer]

Just deionized water. Lazer is in a conditioned space so no chance of freezing.

[@ChrissRollex]

@TheGarageEngineer, thank you for your reply! I've noticed that after using deionized water 2 or 3 times, it tends to get a bit cloudy. How can I prevent this? Do you recommend anything like antifreeze or another solution? Of course, always with safety in mind for the laser tube. What do you suggest to avoid this?

[@TheGarageEngineer]

@@ChrissRollex I’ve never seen mine get cloudy. I just worry about that the flow is constant and water is chilled. Unless you have issues with cold temps. I won’t worry about the cloudyness.
