In an Orchid archive someone mentioned it is important to get more
expensive regulators in terms of safety - I'm not sure if those
offered with Otto Frei are considered the best to use by you all.
Also, if the combination flashback arrestors/check valve are
The water torches are very safe, as they do not compress gasses,
they make the fuel as you need them, but you are right, they run a
bit pricey. Also, the bigger models, which are more expensive, have
the best capability for larger flames, which can be necessary for
The MECO is a great choice for a torch, a real workhorse,
beautifully made, and will last many lifetimes. I love this torch.
Call me crazy, but I took the Meco’s brass body and polished it all
to a high finish. It is a very regal looking torch! I’ve got a
special torch tip set on mine, so the flame is perfect, as tiny or as
large as I need it.
The Swiss Torch is also a beauty. Pricier than the MECO, when you
start buying all the tip combinations, but beautifully made. I’m
nervous about the rubber “o” ring connections, but no problems so
far. I use the platinum melting head to do my centrifugal casting
with, and it is perfect for all metals. The casting tip is longer
than the MECO, which reaches into my casting crucible better, keeping
my hand cooler.
My students love the swiveling tip on the Swiss Torch, that can put
those micro-small tips at any angle that’s needed. No special
regulator suggestions. I’ve used cheap ones and expensive ones, they
don’t seem to make much difference at the low pressures I use.
