Your cooler looks pretty good. I wonder, however, if you get into
serious TIGing, if the heat will build up. I was pretty surprised at how
hot the cooler got on my TIG system after some steel welding. (Actually,
it probably gets hotter on Aluminum with AC, but I am still learning the
techniques there, so I weld for a moment and then look at the part a lot.)
I have a Miller cooler with a big fan-cooled heat exchanger on it. The
exchanger gets hot, and the water in the tank eventually gets pretty warm,
too.

note on the cooler getting hot;
don't know how much coolant does the miller cooler holds

My Miller cooler holds just short of a full gallon, including what is in
the torch
hoses. I'm using Miller coolant straight, it is supposed to help the
pump and
prevent corrosion in the torch, etc.

On mine, the fan is mounted on the pump motor's shaft, so it runs all
the time,
too.
