Right?

Yep,
Small tip, small kerf. Depth corresponds to width.

I have a small Victor hobby torch I bought decades ago for use on angle-
irons, and the like under 3/8" thick. Lots less messy and more
conservative of gas than the big torch, but not a lot slower, so long as
the material isn't too thick.

On cutting stuff like 3 x 3 x .120 tubing, it is good to almost lay the
torch down so that the flame attacks the metal at about a ten to fifteen
degree angle. You can cut about two inches with the O2 jet, and it will
be VERY smooth. If you want the raggedy look, you can bring it up to
ninety, stopping somewhere in between. But if you want real thin stuff
cut clean, lay the tip almost parallel with the surface. Now, we're
talking about thin stuff. Under 1/2". Yes, a 1 tip would be good. Use
4# acet to cut up to one inch thick, and vary the O2 for the thickness
of the metal, as well as changing tips if you get into 1/4" or 3/16"
stuff. Just depends on how you want it to look, and how much grinding
you want to do.

This time, I just want to cut up some fluffy scrap to take less
space. I do no care about the looks.

We have a propane track torch for cutting plate. It works extremely
well, the cut is super clean and super straight.

Try it with the torch pointed almost parallel with the surface, just a
bit downward. The O2 will blow longer cuts than having it at a right angle.
