Default O/A welding question: tip size

Many are balanced pressure so 5 psi and 5psi might do the job,

32psi? That sounds more like "cutting tip" O2 pressure, not welding.


Yeah, you're right, it is. My mistake.

Ever try to weld with a cutting tip? Not easy, but it can be done! g I
wouldn't try to weld an airplane with a cutting torch, though.

Quite frankly, I do so little gas welding, I just play with it, until I
like it. I don't remember what I use. Does around 12 pounds sound about
right? That's what seems to come to mind.

Still, 2 pounds is not very much. I tend to use the knobs on the torch to
control the flow, as the most important control. I would think that if
you were using two pounds, you would have to have the knobs all of the way
open. I would think it would be hard to keep a consistent flame, like
that.
