mapp gas

[stephenacarcher]

how many use mapp gas to do refrigerant line silver soldering?

I had a self lighting Burnzomatic torch. With Mapp Gas, it didn't get hot enough to braze 3/4". I moved on to an acetylene turbo torch, and finally oxy-acetylene.

I never have or never will solder refrigeration line. Brazeing with silver is the only way refrigeration line should be connected.

i'm a minimalist. if the smallest set-up can do the job, then i'll schlep it 3+ blocks on my 2 wheeler to the job

Do people still solder? Bet that works good with the high pressure! Nobody who does quality work will solder.

MAPP can braze as well as solder.

I have done both.

I prefer an oxy-acetylene torch because it heats faster and, I think, does a better job.

I tried the turbo torch and didn't like it for brazing. Oxy/acetylene for me.

thanks for the help ,i was asking more about brazing refrigerant lines with 6 or 15 % rods. i feel that it takes to long to heat up with the mapp gas burnzomatic set up and would be better with a acetylene or oxy- acetylene set up.

They don't make mapp gas anymore. I think about a year ago the only factory that produced it for all the different companies decided to shut down or something. The replacement stuff still comes in a yellow can that looks the same, but it is now called map gas and it doesn't burn as hot.

i was kinda conducting a poll was the reason for this thread i have someone who thinks mapp is the way to go for a/c and refrig work i do not, and was wondering if i had a leg to stand on.

I use a TurboTorch Extreme self-lighting TX504 & mapp for plumbing only.

Oxy/acet for everything else.

How's MAPP for sniffing? upper? downer? hallucinogenic?

I used MAPP Gas to solder up some copper water pipe, but I don’t think I would even think to use it for refrigeration.

I once had to repair a system that someone else put together and I was wondering if they may have used something like MAPP, because all the fittings just kind of blew apart. I ended up just cutting it all out and started over.
