I think that what is happening when I use an O/A torch to cut cast iron is
that the preheat is melting the metal and the oxygen jet is blowing it
aside. Way different from the sharp, clean cut (burn) I get with steel when
things are set up correctly.
So, a torch will 'cut' things that it can't 'burn'.
