Appreciate your comments Bob.

As you probably know, the fan would be extremely easy to control by just
setting a bi-metallic thermostat on top of the transformer with some thermal
grease and one wire of the fan connected in series with the thermostat.
Normally, open, of course.

Can one not weld aluminum easily with the Dialarc h.f.?

k

I routinely weld aluminum down to .050" with my Dialarc HF, have
done .030 aluminum with it. Other machines would probably be better
if you plan to do very thin aluminum, but .050 and above are easy
with the Dialarc. I've also repaired broken aluminum castings,
like a pressure washer manifold and a trolling motor mounting clamp.
I'm just an amateur, but my welds look OK and they seem to hold up in
service.
