Am I the only one that reads old stuff like this and gets a good laugh out of it? Good grief, I am getting old! Hay, but at least I did my own research to learn more about what kind of coolant to use/ not use.

P.S. What ever happened to Sundown II, his responses are like reading the classic comics on Sunday mornings.

 

I am digging up bones here, I just "winterized" my Watermate1. This is what the sticker said......

So with that being said I liberated a gallon of the propylene glycoll we use in a refrigeration unit at the plant, we order 12ea 55 gallon drums at a wack so me borrowing a gallon is no big deal. This stuff is good for -50 and contains corrosion inhibitors, it is orange like other "coolant" I have seen.

You all are pussies. I just use straight Jaegermeister, and drink a little after every project!

 

We get cold weather here, I am worried about the condition of the coolant in my coolmate3. I will drain it and visually check it but am thinking of just replacing with dexcool just to be sure it won't freeze this winter.

 

Dexcool will work just fine, half dexcool half DI water.

 

Does the anti-freeze "wear out" in a TIG cooler?

 

I've had my cooler running a couple months now and it's a little on the brown side. Also has a slight odor. I used anchor brand coolant at a50/50 mix. I'll probably swap it out here shortly.

 

I would not use bleach. Too corrosive, and too hard to rinse clean.
I would use CLR, or something similarly acidic. Look at the instructions for cleaning a coffee machine.

 

RV antifreeze is propylene glycol.

 

What if you just wanted to bleach the pump and tank? The torch is new so not much worry there.
