Not to mention a bottom-of-the-line stick welder with its maybe 20% duty
cycle isn't the greatest choice to power a spoolgun ..

I stay confused much of the time. So maybe someone can explain things
so I really understand it. Much of MIG welding and flux core welding
is done using short circuit transfer. And for that it makes good
sense to me that one would want a constant voltage machine. But when
you go to spray mode, do you really need or want a constant voltage
supply. It seems as if a constant current supply would work better
for spray mode transfer.
Now as I understand it, aluminum mig welding is done in spray mode.
And the aluminum something association recomends using a constant
current supply to weld aluminum. I also know that one can weld using
a constant current supply with a mig gun as a friend of mine that did
not know any better just did it. Used his arc welder as the power
supply and hooked it to his little 120 volt mig when he needed to weld
something thicker than he thought his 120 volt machine would handle.
After he told me that I tried it and it worked. But that was a few
years ago and I can't remember if I was in spray mode.
Randy, Ernie, anyone?

Yes you can use a Constant Current machine to run a Readywelder, I have
done it many times.
The downside to it is that your voltage will be directly affected by
your arc length (wire stick out).
So it takes a very steady hand.
On a CV machine the voltage is not as affected by arc length.

Thanks John,
I'm looking to use the flux cored though as I read somewhere that you
shouldn't really use shield gas when welding outdoors and sadly my project
is too big to bring inside.

Can you take a welding class somewhere? Good way to learn a lot of
basics in a pretty short time.
I still recommend the stick or stick/tig.
Seems I remember there being an issue with making multiple pass welds
with fluxcore, had to use a different wire and shield gas or something.
If that applies to your project, it's something to research a little.
Whatcha buildin'?
