but it's a 4walls and a ceiling deal.... Does anyone know if those
little yellow bernzamatic MAPP gas canisters burn hot and clean
enough for silver solder?
Yes, you can use those MAPP canisters if the gas is compatible with
your torch head. (Molecule size and all, you know.) I have started
up 2 programs from "4 walls and a ceiling" on no budget to speak of
at both the university level and the community level and MAPP was
the fuel of choice in the start up period.
It is not as clean as Butane but it is hotter. It is not "dirty" by
any means. In my experience, it is an acceptable choice for a start
up student program. It will get the job done for the new jewelry
student. It's OK for rings, links, pendants, etc.
I have found that MAPP is somehow less threatening to The Powers
That Be as it is in a familiar package; not one of those scary big
ol' industrial tanks that administrators are sure will launch
themselves into space at the least provocation. Eventually the
bother of filling out purchase orders every time you want another
little canister of MAPP will cause the administrator to listen to
you when you suggest that the program move up to acetylene which
will last a lot longer between refills. It should be left on site.
You should not be expected to transport it!
I have also tried the mini-torch with those little Butane and Oxygen
canisters, too. Great on small stuff but the Oxygen tank was always
running out right in the middle of something. I was always stopping
to get more Oxygen on the way to work. What a bother. MAPP was the
start up choice for my programs.
