Two questions pop to mind, after dinner:
1) There are many 12-volt water pumps at reasonable prices from the RV suppliers. Why not use one of them?
2) I have done a fair bit of TIG welding with my Miller from 3/8" steel to 0.016 aluminum and have simply used an air-cooled torch. I can see water cooling maybe for heavy aluminum, but then is your 150 A welder up to that? In other words, why do you need water cooling?
