Hi all. We picked up our first tig rig a while back and are trying to get some half decent coolant in it. The whole rig was bough for not much, and the miller stuff is too pricey for my blood. No real concern with freezing, just need something to keep the algae down. I bought distilled water, but I also have some water soluble cutting oil I use in the power hacksaw. It's been keeping the algae away for years in that thing, and it's no where near a closed system. Soluble oil should also lubricate the cooler pump. Thoughts?
tl;dr
I've read to use the real deal miller stuff, too pricey.
I've read to use RV antifreeze, I've heard it gels.
I've read to use regular anitfreeze, I've heard it clogs too (doubt it).
I've read to use bleach. Sounds hard on some metals.
I've read to use water soluble oil. Doesn't seem like a lot of disadvantages other than only being a mediocre biocide.
I've read to use water bed biocide. Seems like another good option.
I'd love to just use what I have on hand and not run out and buy anything if it won't cause any issues.
