COMPARING TORCH GASES (propane,map/pro,mapp,acetylene) TRICKY but easy to understand

If you don’t wanna pay too much money for torch gas, you need to understand the differences in the temperatures that the gas burns at. There have been some changes, but these changes may not be as apparent as we would all hope. In the video I go through the different gases and compare them so you can understand what you’re actually getting for the money. Then you can make an informed decision.

Took me a while to find an answer to my question online and this video did just that, concise and quite humorous, thanks

Excellent delivery of need-to-know details

I went out and got the TS4000 self-start nozzle with a bottle of MapPro today and it enabled me to finish a brazing job that I was unable to finish with the Propane bottle and standard nozzle. Yay!

I thought I recalled there being 2 P's when is used it years ago. Thanks for helping me convince myself I'm not crazy.

The temperature of the flame is not the only thing that maters. The power output of a MAP Pro torch is generally MUCH higher than a propane torch. I really wish they listed the output power in BTUs/hr on torches. But they don't. However, I've seen tests where they measured how hot the different torches were able to raise the temp of a piece of steel. The Map Pro resulted in almost 2X the change in temp for the hunk of steel. To help understand why power is more important them temp, imagine you're dumping 500 deg water on something with at 1 drop/sec. Now compare that to adding 510deg water (only slightly higher temp) but you're dropping it at 2 drops/second. The 2nd one isn't just better because it's a higher temp (510 vs 500) the more important number is it's delivering 2x as much water per second. That's analogous to why a MAP Pro torch delivery WAY more power than a propane torch even though the flame temp is only a little higher.

Thank you for breaking that down! Very helpful and also explains why years ago it was much faster to complete a task with MAPP gas vs MAP pro today. Well done!

You can buy mapp gas from uk as much as you want.. I'm an italian plumber working in the UK and I always use the one you wish it was full

Mapp stands for mixed acetylene-propane. Came on the market about 60 yrs. ago, supposed to be safer than pure acetylene, but rarely used

i was not able to melt solder to replace outdoor 1/2 faucet yesterday using propane... went autozone spent $12.50 for map pro... it worked. but it was more than likely water still in pipe ...no one was home so i could not open indoor faucet after shutting off main... finally i was able to open indoor faucet and solder melted...

[anthonycesario]

Thank you. This video ended my confusion for this subject, and that's not easy.

[freddygill]

Thank you so much. It is absolutely obvious that the consumer is intentionally mislead through the naming of MAP/Pro. MAPP Gas is a completely different product. An example of corporations colluding to hide knowledge to maintain an unfair advantage. Also known as intentional deception. I am deeply saddened by the obvious censorship of information that was at one time shared freely by all. You have helped to bring light into the world. Thank you bro!

[owenlee]

Thanks for sharing the information and explaining difference. I initially thought that MAPP and MAP/Pro were similar.

[DlcHas]

Depends on the size of pipe that's being soldered as well. Regular propane will solder 1/2 & 3/4" copper just fine, accessible location. However, 1" type L copper in a difficult spot, will be a pain. Better off using mappro in this situation.

[katzenpapa]

Thw TS8000 handle is where it is about though. It even makes propane hotter, but for some reason the heat transfer if higher with the MAP Pro.

[micahhawkes]

3 dollars! Man it’s $9 here in Canada, and $15 for mapp

[carlossilva]

I'm told MAP doesn't flare like propane (while the torch is cold), so that might also be an advantage.

[longlimboy]

Thank you for explaining this so clearly. Thank you so much lol

Holy crap, never knew that - wow. Thanks 👍🏻

Mapp Gas 1, 500 Degrees Hotter than Propane ????

The numbers that I have found indicate Map-Pro gas burns hotter than the old Mapp gas except when used with oxygen.
Current prices (Aug 2020) are about $3.50 vs $12.00 for disposable 14 once cylinders (difference of $7.50 or 3.5:1 cost ratio).

Acetylene/oxygen 3, 160 °C (5720 °F)
Mapp Gas/oxygen 2, 925 °C (5300 °F)
Map-Pro Gas/oxygen 2, 871 °C (5, 200 °F)
Propane/oxygen 2, 800 °C (5, 072 °F)

Map-Pro/Air 2, 054 °C (3, 730 °F)
Mapp Gas/Air 2, 020 °C (3, 670 °F)
Propane/Air 1, 980 °C (3, 596 °F)

I recently watched this video to educate me on the differences between the various tanks of gas that are out there for the public to purchase. My understanding after watching your demonstration, is that “they” no longer make the Mapp Gas but only the MapPro. And yet last night I was on our local Home Depot and much to my surprise they had “Mapp” gas for sale. Both kinds in the yellow tanks. So am I missing something? Or did they decide to reintroduce the older kind of product to the consumer again?
