Ooo, I want one ![:P](./images/smilies/tongue.gif)
Is there anyway to calculate the temperature of its flame?

I think the temp is listed at 3500*K That's about 3200*C which beats HHO at a
mere 2800*C...
I think I want one too.

True. However, it will not be for the lack of material.

Who has heard alot of
"War Stories." The one I
most believe was from a
Sargent I served with in
Germany (ca. 1964).
When I asked about his
experience in WW II —
he just turned his head
away with a "1000-yard stare" —
and said nothing.
That's the kind of war story
I believe.
All gave some ... some all.

I think I'll stick with H<sub>2</sub>O producing flames for now . . . super heated HF gas sounds a little unpleasant.

i going with the thermal lance as it turns concrete in to a puddle which im not sure if it burns hotter than an atomic hydrogen torch but ive heared
of some using aluminum or magnesium rods to make it burn hotter in the pure oxygen enviroment of the iron pipe

Temperature is not everything. When it comes to cutting iron and melting refractory(rather than welding), I'd rather have a gasoline torch. It's the
most powerful cutting torch out there. Demonstration:
http://www.youtube.com/watch?v=Nvs4fuOBIZw
The fuel is not expensive (contrary to C2H2 or magnesium/ aluminium in your thermal lance). When it comes to welding, I'd rather have an AH welder
because a gas torch cannot be used for welding metals together.

Forsooth! La article on the HF torch sez they welded copper to
copper with it. I have use my Oxy-acetylene brazing torch to
weld US nickel (5-cent) coins together. Unkl Tungsten told his nephews
that Superman did it with his X-ray vision.
Brazing is welding, and if'n your using iron rods you are melting
the work along with the rod.
Someday I am going to find a way to weld with my plasma
cutting torch ....! Heck if people can weld with an carbon arc ...!

Bunkum.
Anyways in all those Oxygen/fuel (Acetylene, Propane, Gasoline or whatever) torches cutting steel, it's the Oxygen that does ALL the cutting. The
O2/gas flame heats up the metal to red/orange heat and then a lever is pushed which sends a blast of pure Oxygen through a hole in the middel of the
nozzle of the cutting head and when the O2 meets the red hot metal the temperature goes WAY up (Iron Oxidation) and this melts more and blows away the
Iron Oxide formed.
Oxy/fuel torches will not cut stainless steel. They may cut a thin piece very badly but it will be a mess. It will take a very long time to naw
through a thick piece (totally impractical).

I know the oxygen does all the work when cutting, but when you are cutting pieces of metal that dissipate heat very fast, you better have a torch that
can deliver a large quantity of heat in a short amount of time, otherwise you'll spend an eternity waiting for the metal to warm up. A gas torch can
easily deliver more heat to the metal in a given amount of time than any other torch.
And one thing about stainless steel, why would you bother cutting stainless steel with a fuel torch?!! Rarely do you ever use a beam of solid
stainless steel that cannot be cut using a saw (because it's so expensive).
I like the atomic hydrogen welder because it gets hot enough to melt pretty much anything (including refractory) and because it doesn't introduce
impurities into the material (except for atomic hydrogen).
In any case I like both because there isn't a "one size fits all" welding and cutting torch. A gasoline torch is great for cutting metals, and an
atomic hydrogen torch is good for melting refractory without blasting it out of the way and welding metals together.

Bah, I realize my mistake.
Sorry guys, I said gas torch, but I meant GASOLINE torch, which is used exclusively for cutting.
Sorry about that, I thought I made myself clear, but apparently I didn't.

Not sure on the gasoline torch but at least with acetylene torch you can coat metal with soot. You may ask why would I want that? Because soot burns
off when said metal is 500 degrees Celsius. Real handy in certain brazing operations, especially aluminum alloys.

... and I was scared of a hydrogen torch. Eeek!
The MSDS for the thing would be 900 pages long.

If you want bragging rights to the hottest torch on your block (or on-line group) look up plasma torch designs. There are schemes that generate
temperatures of 30,000 K or so using helium as the fluid.
There was a column in the old Amateur Scientist column from Scientific American where a teenager made one that ran at an estimated 15,000 K.
