I was going to build one of those, but my 175 lincoln torch seems to work fine as I am just a hobbiest...maybe in the future.
Can you post more pics of the new pump and model/source/price when you get it? Also, what kind of water cooled torch did you end up getting?
I can't believe you have your 175 mounted so high up. That welder is HEAVY! I built my cart and put the welder on the bottom and a sheet of metal on the top to set the work on.
