Ever wonder if those new hyped-up swirl type propane torches are hotter than your old torch?Also, does running propylene gas really produce more heat/temperature than running propane?Me too! So I did my own tests...First I tried heating up a piece of aluminum (1.5 inch wide x 6 inches long x 1/8 inch thick) and measuring the surface temperature with a remote infrared gun. The problem was the aluminum cooled so quickly that I couldnt get consistent temperature readings.Second I tried heating up a piece of steel (1.5 inch wide x 6 inches long x 3/32 inch thick) and measuring the surface temperature with a remote infrared gun. The problem was the same as with the aluminum, the steel center hot spot cooled too quickly to get accurate temperature readings. E.g. A second or two delay in taking the torch flame off the steel and swinging the infrared gun on get a reading and the center temperature could drop almost 100 degrees F.What I did notice was that the newer torches and propylene heated the steel better than the older torch with propane... I could see that because the area of red hot was larger. So thats the route I went with these tests... how long until the center 1st turned red, how long until the center red spot was the size of a 25¢ piece and how long until the whole 1.5 inch width of the plate was mostly all red.So that became my test. How long did each torch/gas combo take to heat a piece of steel (4 inch long x 1.5 inch wide x 1/16 inch thick) to red center, 25¢ size red center, and finally to 1.5 inch full plate width red. I used several identical pieces of steel all starting at the same room temperature.Heres some photos of the tests in progress...Here are my rough results...And the answer is... you can see for yourself:A)the new swirl-type torch heats the steel plate faster, andB)propylene heats the steel plate faster than propane.Rick V 1 Airco Heliwelder 3A/DDR3 CTC 70/90 amp Stick/Tig Inverters in Parallel1 Lincoln MIG PAK 151 Oxy-Acet
Reply:Great test and info, Rick - thanks!Can you take some pics looking down into the torch openings? I'm curious if we can tell how the torch construction differs. (Especially between the two different turbo-style torches.)

Reply:You sure that yellow can is propylene? All the ones I have seen are MAPP. And MAPP does throw out more heat.My name's not Jim....
Reply:Great test.I find the yellow mapp gas lasts a LOT longer than propane. It's definitely hotter. I have a benzo-matic like Stick-man posted. Best I've owned in these little torches. Bought it as part of a package with two bottles a few years ago. Just started using the second bottle this summer. I've had the same bottle on my torch for months and months. I use it several times a week. I'd say mapp gas lasts the longest because it gets hot right now and you simple don't use a lot. Propane is too slow so you use a more.
Reply:I got turned on to MAPP by the plumber that put in my water meter. I asked why he was using it instead of propane cuz I had never seen anyone use it before. He told me that since it works so much faster, they can do more jobs in a day and make more money. The mapp is more expensive, but he said the cost is a wash due to it being so much faster. I also have one of those fancy torches. I'll have to find a new one now though. I noticed the flame wasn't acting quite right and the rubber seal where it mounts to the bottle is all torn up. Lot's of use....My name's not Jim....
Reply:a little torch like that and a bottle of mapp is how i start the smoker up....

Reply:Thanks for the info, Rick. Because of this thread I've added a "swirl" style air-propane torch onto my "wish list".

Reply:Originally Posted by Rick VWell I did that - used Macro mode to no avail. The problem is the tip of the torch facing you is not a flower Really, it is only the diameter of your finger and there is nothing behind it for several inches. My auto-focus only camera doesn't know what to focus on; it doesn't seem to detect the small area of the torch tip.Maybe I could try again from a further distance and using a bigger format (more pixels) to maintain the resolution. A longer distance might also help the light from the flash (located beside the lens) get further into the torch tip. Taking flash pictures of shiny metal objects is a challenge too! Another possibility would be to poke the torch tip through a piece of grey cardboard - at least the autofocus should react better.Thanks for the comments...

Reply:cool post thank you for sharing. its always nice knowing little thing like this when you need to use a torch..... I know im buying the MPS for my small torch from here on out.

Reply:Hi LOWERnU... your link shows many torches!I'll deal with a few... in order of increasing temperature of flame.This appears to be a small, highly portable, butane/air torch. It would likely be good only for small thickness, small piece size brazing jobs.This is BernzOmatic 8250 remote torch. According to the BernzOmatic web site, this torch is similar in temperature/heat output to my BernzOmatic TS839 torch - both using propylene/air. I'd expect similar performance.This is a propylene/oxygen torch. Dealing with oxygen torches was outside the scope of this article.Any propylene/oxygen torch will outperform (temperature) any of the torches discussed here - because the fuel oxidizer is oxygen, not air as with all torches discussed here.However, I know a few folks who have purchased this torch and they complain it doesn't burn for long ~10 to 15 minutes. The reason is that the small oxygen tank is a low presssure tank (~300 psi) and only contains about 1 to 2 cubic ft of oxygen... only enough for a very short time.I hope that helps.Rick V 1 Airco Heliwelder 3A/DDR3 CTC 70/90 amp Stick/Tig Inverters in Parallel1 Lincoln MIG PAK 151 Oxy-Acet
Reply:i amfixin to do some work involving heat and beat and tack and bend on some 1/2" square solid bar and tried the bernzomatic propuylene-air torch.. takes toolong, forget about getting a puddle...no real comparison to oa with a smal welding tip..i think these torches are designed for soldering and brazing small pipe...
Reply:The torch I pictured I believe is oxy/mapp gas. Isn't mapp gas give you the cleanest weld? And best for welding and brazing?
