Any one ever do this. I was at j mart today. A local contractor was picking up cases of mapp. I asked of he also plumbed. He replied. Nope I use this to braze my ac linesets. He could sense the wtf going on in my mind. He explained it. Claims he saves a good bit of money using mapp.

Mapp gas works fine on small lines like 3/8 " and as long as you're not in a spot where heating for an extended period of time will cause a problem it works O.K. on bigger lines like 5/8" and 3/4". I've sweat in plenty of condenser units with Mapp gas when I didn't have an acetylene or oxy/acet torch available. I still keep some Mapp gas with me as a backup in case i run out of acetylene or oxygen in the middle of a job, especially on a weekend. I wouldn't try to do an RV with Mapp gas but for most residential work you can get away with it.

IMO nothing beats an Oxy/Acetylene torch.
And I always carry a spare bottle of each gas.
One ALWAYS runs out when they least expect to.

often used map gas , good to have as a back up ,

What he failed to mention was his next stop was picking up some Stay Brite 8 :grin2:

I use a turbo torch air / acetylene as backup. Oxy acetyl is my main torch

I carry oxy/ accet, air/accet and map gas. Mapp gas worked good before they fixed it. Now it ain't so good.

The only thing I dont like using my Oxy/Acet on is real small stuff like cap tubes, thats where my turbo torch comes in.

I use mapp with oxygen for the sole reason of weight. Used this setup for 15 years. Lighter is better.

Mapp with oxygen? Never seen the set up for brazing. I have seen it for cutting very thin metal but not brazing. You got a link

This looks like the adapter I have: http://www.amazon.com/Uniweld-FV600-Regulator-Disposable-Cylinder/dp/B00FPGCU8O

I normally use oxy/acet but if I run out of acetylene I can hook my MC hose fitting to this adapter and use Mapp gas with it along with the oxygen.
There are also small Mapp/oxygen complete kits you can buy. Just google it and you'll find all kinds of them.

Turbo acetylene is way to go cost,speed,get an mc tank for roofs and attics

Dug out the Oxy/Acet for a TX valve in an old Norlake .

 

[ga-hvac-tech]

I remember a TXV change I did with StaBrite8 and the Oxy/Ac torch....
Cranked down the pressure on both gases, had an itsy-bitsy little flame...
And it soldered up quickly and clean.

The only thing I do not like about using StaBrite8... is the flux. I do not like flux in my systems.

Never try it. The oxy acetylene comes with gauges so when its low trade them in. I use a B tank. Last a long time. I carry 50' hoses so attics or under the house is not an issue. I even drilled out my #2 tip to like a #54 drill. Which is like a 2.5 tip

 

[lytning]

I keep a spare MC & Oxy tank at house.

 

[BagsOfFlex]

Yeah mapp and oxygen is a great combo. Easily solder 1 3/8" with no problems. Takes all of 2 seconds to switch out a tank and no more having to buy a high dollar act tank to switch out. Here's a link to the one I have used for atleast 5 years now. No more fooling with regulators that constantly get off while slamming around in your truck as well.

Now someone make a back back torch setup.

NewSpring, What's the model number of the set up your using. Which tip do you prefer? Thanks!
