    the "water" torches, such as the Spirig machines, ARE known and
    accepted, by those for whom they are good solutions.  But they are
    characterized, among other things, by relatively small flame sizes.
    This makes them well suited to precise assembly and soldering of
    small items, especially in metals like gold and platinum.  For those
    workers doing larger items in silver, which is highly heat
    conductive,  the oxy/hydrogen flames can be somewhat harder to use
    and control than the much larger soft flames of an air/acetyelene
    unit.    It just depends on what youi're doing.  I own and use both
    types of torch, though sadly, my water torch isn't a spirig, but an
    L&R (which still works just fine, thanks). for many tasks, it's
    perfect.  but for many others, I simply prefer the traditional
    torch. While I'm sure there are larger versions available, I've never
    seen a "water" torch, of any brand, that could do a good job of
    things like melting metal for ingots or casting, or annealing larger
    pieces of silver jewelery.  

    And there's one other little detail... 

    Cost.  For the cost of the average "water' torch, I can set up
    several oxy/gas torches...  While the water torches are very nice for
    precise exacting jewelery work,  there are a lot of craftpeople who
    simply do not have the budget to afford one.   Even the older used
    model I bought on ebay wasn't cheap...
