Hi all,
I inherited two MAPP torches from (I'm guessing) late 70s or early 80s, both of which had partially-full cylinders. I've read about the replacement (at least in the US) of old-school MAPP with the newer formulations, which don't burn anywhere near as hot. (From what I've seen, original MAPP was ~5,300 F vs ~3,700 F for the new stuff)
My question: can I use these older torches (which were stored in a dry basement & work fine) with currently-available MAP/Pro cylinders? The threads are physically compatible, but wondering if there's anything about the flow rate, flame characteristics etc. that might make this a bad idea.
(I'd use these for sweating 1/2" - 3/4" copper, and occasional de-soldering joints, in case that makes any difference)
Thanks in advance for any advice,
- Mike C
