I'm thinking about how I'd assemble a water cooling system for a TIG welder, and looking for tips and tricks.

I just picked up a small submersible 110v water pump, and it seems like that thing in a 5 gallon bucket should do the trick. I'm also thinking about using a heat exchanger of some type, maybe from a dehumidifier.

I've read other posts talking about using a automotive water pump- what else have you used or improvised to make yours work?

Thanks!
