I love my oxy/acetylene torch. Somehow, I have never gotten one before. Now I am the death-god that can shoot 6000F flame and burn through all that stands before me!
A quarter placed in a graphite dish turns into a little puddle almost instantly.
For cost reasons I may switch to propane/oxygen – acetylene is pretty expensive and the measly 5500F temperature you get from propane/oxygen is probably sufficient. (There is an acetylene gas shortage for the forseeable future thanks to a 2011 explosion at the US’ only acetylene production plant in Kentucky [acn])
When I said I was getting one my neighbor Bob, of the wise advice, said “sometimes when people accidentally cut their hoses, they die while they’re trying to close the regulators. Just grab the hose and crimp it, then close the regulators.”
