Odd change in laser penetration

Absolutely. Today is a day off lasering…

The CW3000 is an ambient chiller, it can only cool water to the ambient temperature of the environment you are in. They’re pretty good indoors but might not be the best in a shed in the summer. I’d suggest considering an active chiller (one with refrigerant) if it’s affecting the bottom line, however they’re about £500 depending on where you get it and the model.

I think i can manage - it’s only really an issue in the summer weeks, and I have no issue with getting up early to laser when it’s cool, then having the rest of the day & evening to myself.

It’s 0930 as I type, and I switched the laser off about 40 minutes ago as the temperature on the chiller rose to 25C. I’m gluing together a lampshade prototype as the family stumble about getting breakfast, then we’ve got the day together (Yay for school holidays!)
