Hi,

I just recived my first chineese lasercutter 150W.

I have got rid of all the bubbles in the tube. But each time I turn on the water cooler there are more bubbles.
Im using destilled water.

How can I make the system bubble free ?

Best regards

Edvin

Personally I let my pump circulate the water for a few minutes before I start cutting and leave it running until the water has cooled to room temperature afterwards

I have just water tank at this moment (not cooler) and serious water bubbles appears ONLY when outlet of laser water is NOT submerged i tank. after start water pump it's does not matter.

Not sure if it applies to the larger tube like that, but I had to turn my tube so the inlet and outlet face up, that way the pump forces the air out immediately.
