A heater core for a tig welder cooler heat exchanger? Hope this is okay in the race section as this is where I lurk and it seems like similar topics come up here once in a while.
Wondering if it will be enough. I think it will except for maybe thick aluminum. I scored an older Esab 300 amp welder minus cooler a couple of weeks ago. Has a new water cooled torch with it.

The nice thing about it is the torch head is so much smaller than my air cooled unit on my Lincoln percision tig 185.

I know someone on here has built their own cooler. Just wondering what you may have used for a heat exchanger. A/C evaporator maybe if a heater core isn't enough. I already got a brass pump off ebag dirt cheap and a motor. Any help would be appreciated. Beep
