Mapp or acetylene? - Plumbing Zone

**Bill** · 07-16-2008, 11:28 PM

I used to like my acetylene tank, but it got too cumbersome and got me a map tank 2 years ago. I love map, quick. Also I love the self start and the tip dont get hot, and much easier to carry under a house. I do however miss the smaller flame which I liked.

Map is the only tank I use, good enough the silver braze the smaller size lines also.

I have not silver soldered with map before, always my acetylene. I did not know map would heat hot enough to do that with

Propane.

**Bill** · 07-16-2008, 11:34 PM

Propane! I thought that was a thing of the past!

Ron · 07-16-2008, 11:34 PM

Oh yea, medical gas, it will get those fitting red hot.

You are paying more for MAPP or Acetylene than I am for propane, and in most cases you don't need the advantage of the added heat, I can easily soft solder 2½" copper pressure fittings with propane.

yeh, but how long does it take to get say a 3/4 fitting hot enough to cause the solder to run with propane as opposed to map?

I love the speed of acetylene, and I only use MAPP, faster then propane in my mind.

I use self starts. Anything over 3/4 gets acetylene. so 1" and up.

You're kidding right? Propane is pathetic. Then again I am a service guy, so all the pipes I solder are wet....propane doesn't cut it. I started with acetylene bottles, now I use MAPP.
