    Re: Building A Tig Water Cooler For Dummies!!!

    Tested my home built cooler last night.
    My goals were:
    1. Fit in bottom of welder cart
    2. Inexpensive, but reliable
    3. Quick to build
    4. Easy to remove from cart and switch between air and multiple liquid cooled torches.

    I used a carbonator pump and tank and basically just re-plumbed it so the carbonator tank functions as a reservoir and added a filter and bypass valve with pressure gauge. I used carpet cleaning quick disconnects that I found on Ebay. I started to add a filler cap to the tank but just used the pump to fill the res with 2 gal of coolant. Since it only has one very small opening to atmosphere I don't expect to lose volume very quickly. I don't usually weld for long periods so I decided to try it without a heat exchanger and see it there is enough thermal mass in 2 gal of coolant to get the job done for me. After about 30 min of welding aluminum at 150amps last night the coolant tank rose about 4 degF. I think it will probably work unless I end up doing a large aluminum project on a hot summer day.

    I appreciate this is an old post, but my god @code4 this is stunning! next level.

    it’s inspired me that’s for sure, I would love to see any build pics?

Currently no heat exchanger, and with the moderate welding I do at the house, I have not had a need for one yet. I may plumb a transmission/oil bar & plate cooler in line in the future if needed.
