My DIY cooler is pretty basic.
25 liter tank and a pony pump; no heat exchanger yet.

The pump output is just a little over 1 liter/minute @ 15 psi. I used this particular pump because A- I had it, and B- it's compact.

This output however, seems to me to be on the low side, so my question is:

What is the maximum allowable exit water temp, @ 1 liter/minute, for the PP256 water cooled torch ?

Thanks,
