    Hi Mark, Most low temp work of this kind is done with soldering irons
    or coppers not torches. The flame temperature is just too high and
    it is just not controllable . So for things like sheet metal work
    and zinc counter tops and such the standard practice is to use large
    masses of metal (soldering coppers range form 8 oz to 4-5 lbs )
    heated to 500-1000 degrees F and they are applied to the items to be
    joined to raise the temperature of the joint to flow temperature of
    the solder See if you can borrow a big soldering iron (electric) or
    get a soldering copper which is a bar of copper with a pyramidal
    point on the end of a steel shank and a wooden handle. You heat the
    copper bar with a torch or furnace (go to mcmaster.com and lookup
    soldering copper) and then apply to the work to be soldered.
