If you’ve been using torches for a long enough time, you can do
almost anything with whatever torch you have at hand. A lot of people
like the Little Torch, and recommend it to others. I have one in my
studio ( a student is using it to fuse small jump rings right now…)
but we also have a number of other dual-fuel torches as well. We also
have 2 Prestolite ( acetylene/ air) torches, which get used for
larger soldering jobs, annealing, and ingot melting and pouring.
The problem I have with the Little Torch is that it can’t be used
for larger silver projects, because its interior plumbing is too
small to allow larger amounts of gas, regardless of tip size, to pass
through to make a larger flame. So a Meco Midget torch with a 1.5 mm
hole in its tip could produce a far hotter flame than a Little Torch
with the same size tip, due to its larger interior tubing size.
So the Little Torch is extremely useful for smaller soldering jobs,
and melting of small amounts of metal.
The problem arises when you need much larger amounts of heat, then
the Little Torch just doesn’t have the “horsepower”.
Since silver is the most fabulous heat conducting metal, it takes a
lot more torch heat to compensate for the heat conduction silver is
noted for. Where one could get away with a smaller torch for gold
work, silver requires some serious heat…
