I need a new torch for student use. It has to be small,
transportable. I saw one at Home Depot that I haven’t seen before,
it has tiny regulators and uses oxygen and Mapp gas (disposable
tanks). The package says Mapp gas. It’s a great little torch with
a small tip.
My question is, can you use such a torch with propane, or if it says
Mapp, do you have to use Mapp? My understanding is that Mapp gas is
much hotter and not appropriate.

I got one of those torches and like it just fine. If I recall right,
seems that when I tried to use it with the Mapp gas that there was a
whole lotta flamin’ and a whole LOTTA of black sooty ash flying
EVERYwhere! Ever since then it’s been hooked up to oyxgen & propane
instead. Sometimes I’ve had to monkey a little with the regulator
knobs to get the right mix of the 2 gases to get a small flame, but
with some practice…One drawback is that the oxygen runs out pretty
darned fast. But they’re certainly inexpensive enough to justify
getting one and giving it a try?

The biggest problem with those " throw away" tank systems is the
very high cost overall and particularly the low oxygen content in
the tanks. If you can get by with a propane- air , or acetylene -
air torch go this route. The system you are talking about can use
I use propane -air for most everything but also have
oxy-acetylene for very big stuff ( outside jewelry scale).
