I LOVE my shark torch (also called a whale torch and easy torch),
which uses propane gas and ambient oxygen. The torch head has a valve
that mixes the ambient oxygen (the oxygen in the air around you) with
the propane and produces a really nice flame. No need to have an
oxygen tank or to use acetylene, which requires better ventilation.
The torch comes with three easily changeable heads. The flame on my
torch is not as small and hot as an acetylene/oxygen flame, but I
solder well with it. I am currently out of stock on this torch, but
hope to have some in a few weeks.
