O/A welding question: tip size

Mike,

Did the tip I let you borrow help?
I am building a mount for my HF Mobile antenna mount and may need your
help.

Hope to see you at the USO Swing Dance Saturday and the Poker Run
Sunday. If you can get in my 150, you can go with me on the Poker Run.

Someone in the office suggests if I go to a much smaller tip, then the
area I'm heating will be smaller and therefore I may be introducing
stresses closer to the work.
Is that a consideration in the world of 4130? - Mike

Oh - yes it helped; it told me that modern tips will fit on my old
Smith handle - Mike

OK, I'll take that as a "forget about it" - MIke

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.

I always set up for 5.0 - 5.5 psi on both the acetylene and oxygen,
regardless of tip size.
