The light in our lounge is pretty dim, really we should replace all the lights with better ones but we're waiting to redecorate everything at the same time.

We're having a bit of a cold spell in the UK (I'm aware the US has it worse too) but we're not used to cold weather, temperatures dip below zero and we all panic a bit. One of the things that people always forget is that the glass tube in the back of their laser cutter is water cooled. If the water freezes it will expand inside the tube and cause the glass to smash, that's going to leave a hefty bill to replace the tube. Putting some antifreeze in with the coolant is easy to do and it's going to save you the worry. If your laser is in the garage and isn't warm and snuggly inside your house it's well worth doing.

If you have the CW3000 you're going to need 2.25L of antifreeze and if you have the CW5200 you're only going to need 1.5L. The internal reservoir of the CW5000 series is smaller because it actively chills the coolant. Small quantities can be purchased via ebay and the usual sources at sensible prices (or from laser importers at inflated pri…
