    I have and use a Smith Little Torch with oxygen and acetylene, I
    select the tip based on the size of the material I am working with or
    on how quickly something needs to be accomplished. The only thing I
    have found is the #1 tip is very hard to light, I use the #3 most of
    the time, and something needs to be really big to use #7, or I need
    to heat something very quickly to a very high temperature before the
    heat spreads to other pieces of the work. 

    I have had no "dangerous" experiences other than burning my fingers
    a couple of times. The torch set came with instructions on what tips
    were suitable with what gases, I have always stayed within those
    guidelines and have had no problems. I do have flashback arrestors on
    both of my bottles, I don't know if they are required for these
    little hoses but as I have a regular set of welding hoses attached I
    need them because of those hoses.
