Question for the group. It’s winter and time to change the coolant for my K40. I’m already using deionized water. I’ve read of people adding some chlorox to keep stuff from “growing” in the water, anti-freeze to prevent freezing, etc.
My question is, what is everyone doing to their coolant water to keep it clean and prevent it from sapping energy from the laser?
I’ve had my k40 a little over 5 weeks. The laser is in my unheated workshop where outside temperatures can drop below freezing. I’d appreciate any suggestions.
beware with antifreeze as it can increase the amount of current bleed into your reservoir. See more info at http://donsthings.blogspot.com for detailed numbers.
Do not use antifreeze during operation. You have to either heat and circulate the water or drain it if you are not using it.
Some use aquarium heaters to heat and control the coolants temp in winter, you can search the community for that info and others will chime in.
