- Is this gas available in anything larger? The local welding suppliers say no but I can't imagine why not. One guy filled a large propane tank with MAPP but without knowing the vapor pressures of each, that's amazingly dangerous.>>
yes it is!!! Don't DO THAT!
I have a MAPP tank -no longer used (but cannot ship it because it still has gas in it - or I'd offer it up). I believe it is 20 or 22 lb size - I got it at my welding supply. They look about like the old aluminum C02 tanks...
If your welding supply company is brainless - I suggest you try a different source... Also call some local plumbing shops - since they often use it, and may know of a dependable source. Or try buying and empty over the internet.... there is also a 70 lb tank size - but it's pretty big.
your second question leads to the obvious - if you have "outgrown" the hothead...and have discovered it's limitations....
point between the dots" must have something else in mind. What's the next
>step up from a simple MAPP cylinder with Hot Head?>
A minor burner - oxygen and propane is your next step - forget the bigger mapp tank, by a minor, and go on to the next step... a real bead torch.

Quit buying locally - and start buying from the larger suppliers -- both are online - and all the information you could need is available from the books - or if you check the information on the web.... start with my webpage
