Hi,

    When buying a torch, consider the type of work you'll be using it
    on. You need a torch that will put out the quantity of heat (btu's)
    as well as the temp of the heat required by the metal being
    soldered/fused. 

    Without a doubt an hydrogen/oxy torch puts out a high temp flame.
    However, most water torches don't put out a flame with a high btu
    content (amount of of heat). Solder/fusing silver or copper over
    about 1" square generally requires more heat than these torches can
    provide. Working with this type/size of metal requires a higher btu
    content, the type put out by an acetylene/air or an acetylene/oxy
    torch with the appropriate size tip. 

    If you're going to be soldeing/fusing gold or silver in smaller
    pieces an acetylene/air or a butane fueled torch will probably work.
    If you plan to work on platinum you need a torch capable of a high
    temp. However, platinum can be contaminated with the carbon in a
    poorly adjusted torch using acetylene/oxy. The water torch may be
    satisfactory for platinum, unless you plan to use it to melt
    platinum for casting. Then it won't be capable of providing enough
    btu's, but the temp will be high enough.
