    Guy's ...... there are only two things that really matter. One, is it corrosive? and two, does it contain coagulants like those in some automotive coolants. Otherwise have at it and report back! You could probably use Alpaca urine, .... i dunno. Tap water, hose water, etc, are eventually going to calcify, and lime up your little torch pathways. But i guess thats why they make CLR, and lime away. Some auto coolants have radiator coagulants to help guard against small leaks. RV coolant is a different formula. Distilled water, .... sure why not. As far as sub zero temps, .... god bless ya if you can weld in that enviroment! lol! If just occassional work, just dump the water when your done, what is it, ... 2 gallons of distilled?

    Don't get me wrong here my friends, just bein a little tongue in cheek to lighten it up! There's lots of ways to skin a cat!

    Default Using "pink" fluid

    I have been using pink RV anti-freeze(propylene glycol based) fluid in my home made cooler set-up with a PP256 and it starts/welds perfectly. I even added 6oz of "radiator anti-rust with water pump lube" to the mix when I noticed my pump, an in-tank automotive fuel pump, getting rusty. By using a submerged 12v.DC pump and all the various fluids of the mix, I'm probably breaking lots of rules, but this has worked fine since I got the welder in June. I will post any problems that might arise.

    Default Pink RV fluid use update

    Just checked the pump in my cooler set-up. Still no rust, pressure(30psi) and flow (1 qt/min.) are fine, but there patches or green mold floating on top of the coolant in the tank. Probably not a good thing.
