Sounds like a heat exchanger is needed - as one loop from the stinger brings
in hot water and pumps back warm water - another loop is placed to chill the
warming water (water to say a term only) and dump the heat elsewhere. A nice
portable air conditioner that is a heat pump or not - could be implemented
when local power was available. When in the field, a Icebox from a camper
that runs on 12 v or propane might be a nice chiller.
Naturally some kit bashing and creative mind work would have to take place.
Solar cells dumping high current into a pair of wires that in turn run through
a solid state heat sink (ever see the 12 volt camping ice/beer chests ?) easy to bash.
Almost done for you - cooling tank and drain and 12volt plug.
Plug it in and pump 'water' through 3/8" copper tubing - (or other) to a small radiator
that might have been a motorcycle add on kit - back to the 12 volt chiller.
The box always closed and in the shade - and the bottom (where the heat is - on
a larger sheet of metal to conduct ? - truck bed ?

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.
Jon
note on the cooler getting hot;
don't know how much coolant does the miller cooler holds and why it
gets hot, but one thing for sure the new miller 250 TIGs we used at
school the fan does not come on untill the coolant get hot enough.
it may even have some sort of flow control as well, because the sight
glass with the red star in it was barely spinning at 90-120amp welding
it has been said many times by guys here, a 5 gallon bucket or ever 4
gallon will never get hot enough (not even remotely) under normal
use.
I asked the same question back when I built mine and Ernie L. and the
other well known gurus confirmed it.
NO heat exchanger needed. unless you are blasting 300Amp continuosly.
