    Yes, that's what I thought too. They are a small self contained unit
    which require distilled water and some liguid flux that is added, if
    I remember right. I worked at a custom jewelry store where my boss
    had a Hydroflux Welder on his bench. He used it for soldering
    platinum. I soldered platinum at my bench too but I used natural gas
    and oxygen rather than the oxy-hydrogen. 

    What I remember is that it had a relatively small, very hot, flame.
    He often had trouble keeping the torch lit. It seemed to me to have
    very little range of use. I have just now looked one up in the Rio
    Grande catolog. Hydroflux units are still almost $1000 and there is
    a picture of the type of flame they produce. The ad says it can
    solder or fuse platimun up to 22 grams and can solder a heavy size
    13 class ring. I never felt that my boss' unit could do that but
    perhaps the new units are better. There's another one called Hot
    Flame. I've never seen it in action. It is $1690. 

    I'm sticking with my oxygen/propane torch but it would still be
    interesting to hear if anyone in the Orchid group is regularly using
    a "water torch."
