TIG is constant current. MIG is constant voltage. So, I don't
think so.

I think tche answer is " maybe ". Mig in short circuit transfer is
constant voltage. And TIG is constant current. But MIG is pretty much
constant current in Spray Mode. Think about it.
Constant stream of ionized particles.

When stick welding you are using spray mode. Unless you are a really
bad welder, you are not doing short circuit transfer.

So there is no reason you can't do wire feed welding with a constant
current supply. I have a friend ( Sorry Steve, but I really do have
some friends ) who said he used his stick welder coupled to his 110
volt MIG welder when the metal was too thick for his little 110 volt
welder. I did not think it would work and thought he was pulling my
leg. But tried it, and it is possible. It is even possible to use a
AC arc welder with a non-voltage sensing wire feed, but I think DC
would be a lot better.

Yes this sounds like a bunch of horse pucky, but you can try this at
home. Caution if the wire feed speed is not fast enough, you might
lose a contact tip or two. So start with a fairly high wire speed.

Now whether the Harbor Freight welder will supply enough current, I
don't know.

Look at their cold wire feeders that work with tig torches to increase
production.

I've never used one!!!

I have used a spool gun with a CC machine its tricky to get it started but
once going not to bad, but doing thin stuff would bet hard and 90 amps
wouldn't do much any how. The mig would run that little thing down fast. I
see they offer 1/8 7018 rod below that welder, I am sure running 7018 1/8
with that welder has got to be a real joy and a very big test of its power.

Someone told me that there are variable feed rate, voltage sensing
wire spool guns. Lincoln LN-25 is such a wire feeder, according to
him. That guy tried to sell me an arc welder by trying to say that it
was a tig welder, so he possibly exaggerated things a little.

Dennis at Arco Welding Repair has a Hobart box that I think will allow
you to interface a tig with a wire feeder. It was sitting on the floor
last time I was in there. $25 takes it. Might want to call him
