I would like to use some antifreeze in it so that it does not freeze
in winter. I googled this newsgroup and found that people use pink RV
I want to double check that it is a safe idea.
The anti-freeze that Miller sells for use in TIG torches is de-ionized water
and glycol and an anti-fungal.. The result is low conductivity is minimize
theeffects of HF to keep deposits out of the torch passages.

I don't think he means straight happy juice. Just enough to bring down
the freezing point of the water. I don't think it would take more than 5%
or less, with occasional replacement due to evaporation. I don't know if
bugs or slime is likely to take hold and grow in any mix of alcohol other
than a couple relatives of mine.
FYI, you can make your own cold packs by taking a bottle of isopropyl
alcohol (about 70% already) and mixing it in a 1:3 ratio with water in a 1
gallon freezer bag. Put in the freezer and it turns into a slush which is
great for those pains we all get as we get older.
Since my freezer is about 25 degrees or something and the resultant
alcohol mix is about 18% to get a freezing point of 25 degrees, a mix of
about 25% (iso anyway) should keep the freezing point way down there, and
since the percentage is so low flammability will be a non issue. Since I
can light 70% iso in my hand (with some effort) and barely feel the heat,
you can imagine what it would take to light and sustain a 25% isopropyl mix.
If I got my math wrong, please feel free to straighten me out!
