Considering the price of propane vs. acetylene, I think it's a no-brainer. I
vote for a propane torch every time. By the way, Harbor Freight makes a knockoff
of the Magnum torch. It's real cheap. I looked at one in person, knowing what
mine looks like, and it sure looks cheaper, plus it doesn't come with a nice
regulator either. But my torch retails for big bucks and the HF one is cheap.

I haven't had a gas rig for a few years (used to use the ones at work,
don't have any at current work, have not had sufficient need to justify
the expense), but given that people bother to rig cutting torches for
oxy-propane due to lower gas cost, I suspect that propane would probably
be enough cheaper to run that it would make sense if you'll be doing
much of whatever it is you're doing with this.

The propane weedburners only get to about 2400 degrees F.
An oxy-propane rose bud can get to over 4000 degrees and, of course, the
oxy-acetylene rosebud goes even higher.
The weed burners that run on propane use propane and air. You can
also buy "prestolite" torches that run on acetylene and air, but I don't
know that they come in sizes as big as the 500,000 btu weedburner.
You can probably buy a propane weedburner and a 20# propane tank for
less than you would pay for a rosebud, either oxy-propane or oxy-acetylene.
Whatever you do, remember that acetylene is illegal to have at over 15
psi outside the tank!!!!!

My understanding of that is that it's just like any torch but has like 6
jets in it. My idea is to basically take a naturally-aspirated (air, not
oxy) propane burner and feed it acetylene instead.
Drop into the welding supply retail store and ask to see a "rosebud"
tip. Ask your question there too.
Take care.

I have one of these (or something very similar, from Northern Tools).
It's sold for melting roofing tar. It's also dubious to use it
commercially, as it connects directly to the cylinder without a
regulator (UK fire officers throw a fit when they see it).
Handy for weeds and bitumen, but not much else. Big flame, low
temperature. Is your Magnum torch any hotter ?
BTW - What's a "rosebud" torch ? (not a word we use in the UK) I
thought I knew, but it's not anything like the Magnum torch in that
eBay ad.

My Magnum torch *looks* like it throws a lot of heat. I haven't used it
that much yet. I've spent a lot of time around torches, though. I used to
be a shipfitter and spent 8 years where my primary tool was a torch.
I think "rosebud" may be a Yankism. To me it means a torch with a head on
it about as big as your fist, which throws a gigantic amount of heat.

Probably does - not very hot though. That's the problem with mine.

Ah. I thought it meant an oxy-acetylene blowpipe, where there was a
small interchangeable tip on a fixed neck, instead of the swaged pipe
where the neck and nozzle swap as one unit.

I have used 2 rosebuds together to heat a 1,400 lb coupling half that was
about 4 feet diameter, around 14 inches thick at the hub, with a 12 inch
bore to shrink-fit it onto a shaft that was .024 larger than the ID. They
suck up a lot of fuel if you are using a large one, but they will put out
some serious HEAT. I have even been known on occasion to "preheat" my shop a
little with mine till the furnace got going good.
