Mapp is no longer Mapp.

Whats the story with that VTP?

MAPP was hot enough for little tubing back in the day.

If MAPP is hotter, it sounds like a good back up for the regular Aceyletan & Oxygen tank torches. I agree Dr. Z should not have tested the "can torch" in his car

The best back up would be another tank of acetylene. If you run out of O2 get a Harris Inferno Tip

I believe the original Mapp manufacture (Petromont) discontinued manufacturing it . All the new Map has one P in the name. Map-Pro

what is it now & is it still yellow tagged???? Jack

I prefer my Turbo Torch. Just one Acetylene tank. Quick, easy, and just the right temperature, and I've done up to 1-1/8".

thats ok i'll stick with my turbo torch O.o

Same here, if it ain,t broke, don't fix it. Even with all the guys saying, you still use one of those? Or what the heck is that thing.

I use my Turbo Torch all the time. Most my work is under 1". Last week I pulled out my propane / oxy setup to weld some 1&1/8" suction line. Wow one could get to likeing all that heat. I went ahead and did the 3/8" liquid line in a very quick order. Way to much to lug around.

I'm sure somebody could make a propane torch that would work as well or better than an acetylene torch.

In our shop, we have a oxy-acetylene cutting torch. We bought a large rosebud (#9?, maybe #11?) and were trying to heat a pretty big chunk of steel to bend it and couldn't deliver enough acetylene to keep the rosebud fired.

I did some research and found a suggestion to use propane instead. Bought a propane bar-b-que tank and a propane regulator. When we need a ridiculous amount of heat, we unhook the acetylene hose and hook it up to the propane tank and use oxy-propane. I'm sure I get 10x the heat out of propane that I was getting out of the acetylene.

The limiting factor with acetylene is how fast a tank can deliver the fuel. Because acetylene is dissolved in acetone in the tank, you can only get gas out of he tank as fast as it un-desolves. If you try to deliver gas too fast, you draw out acetylene instead.

But propane has no such limit. Open the valve and let it flow. And, propane has more BTUs per pound than acetylene.

The advantage acetylene has is that it burns faster which means the flame is smaller, more concentrated. That's good for cutting where you want a very tiny spot of very highly concentrated heat.

But for just heating something, I don't need to concentrate my heat in a 1/16" circle. A 1/2" circle is just fine. I'm sure a propane brazing torch could be designed that would work faster and on larger diameter copper than a comparable acetylene torch.

The getter done Air/Propane tips are huge.
Would work fine if all piping could be assembled in a wide open shop with nothing else to burn up.
Not sure they could make a similar size tip and flame be as hot as acetylene.
Why wouldn't they make one if they could?

I have an acyletane and oxygen torch. It works well. However, I think that we should keep an open mind on these things. If MAPP or this turbo torch work well, for residential uses- why not use it.

Frankly, if an acyletane tank leaks, there is a much bigger problem than if the Turbo Torch leaks. The Turbo Torch (or MAPP gas torch) has less gas when filled . The question is if the Turbo Torch and MAPP gas are hot enough. I am glad to hear Techs using it in this thread.

Possibly, it can be used in the following manner for residential applications:
* When cutting a line- use a cutter. This prevents oxidation from using a torch to melt the solder. The turbo torch or MAPP gas torches may take too long (if ever) to melt certain types of solder.

* Use the Turbo Torch or MAPP gas, for the alloy solder it can handle to join pipes together.

What do you think of these ideas. Is the Turbo Torch or MAPP gas, hot enough to melt solder needed for residential HVAC work? In other words, is the solder that can be melted by the Turbo Torch and MAPP gas acceptable for residential applications. Is that solder OEM approved?
