Dear all,
For 400w laser die cutter, does it need water to cool the laser head?

For old 300w laser die cutter, we didn't use water to cool it, after long time working, we found lens is fine, no effect on it.

So anyone knows well about it? If need water, we have to design new laser head which can be filled water.

Depends on a lot of factors, sometimes no, sometimes yes
