Talk:Blowtorch

message: I never heard of this being called a "blow lamp" my father had what he referred to as a "blow torch"; this was similar to the one shown in the photo. I would like to describe how this thing worked.  The tank was brass and was filled with gasoline.  Once pressurized gasoline was forced out into a small reservoir under a tube-like affair which had holes in the sides; this was accomplished by opening a valve. Once the reservoir was full of gasoline the valve was closed and the gasoline in the reservoir was lit; this heated the tube. Once the tube was hot the valve was reopened and gasoline then sprayed into the tube creating a very hot flame, as oxygen was drawn through the holes in the tube. This was used to heat items like soldering irons and to melt lead for fishing sinkers and it was considered a very dangerous tool. —The preceding unsigned comment was added by Genet4601 (talk • contribs) 03:47, 24 June 2006.

replies: text: Born and raised in the United States, I have never in my life ever heard the term blowlamp applied to this device. It has always been referred to as a blowtorch by everyone with whom I have come into contact, from my father to contractors, plumbers, and so forth. I suspect that things are a little mixed up, and that the US term is blowtorch/blow torch and the UK term is blowlamp.  This article needs to be researched better and rewritten.  I'd do it myself, but I have too many other irons in the fire right now.Glacierman 00:25, 12 March 2007 (UTC)
replies: text: That makes three of us who have never heard it called blowlamp-suggest moving to blow torch. Chris 08:10, 14 April 2007 (UTC)
replies: text: I only just came across this article. Why on Earth should it have been moved? That is in violation of Wikipedia's rule on national varieties of English. I am English, and I call it a blow lamp: I have done so all my life. If this article started life as "blow lamp" then it should not have been moved unless there was very good reason to do so. I will wait for any replies here before I initiate any action. EuroSong talk 21:39, 17 April 2009 (UTC)

replies: text:  I've lived in England for 20 years and have never heard it called anything but a blowtorch, I'm guessing blowlamp was the original British English term but the American loan has eclipsed it. Either way I don't see any argument for having blowlamp as anything but a British alternative. I would also say that, due to the sheer ubiquity of the term in Britain, blowtorch should be listed as both American and British. 90.197.42.69 (talk) 21:32, 28 December 2010 (UTC)
thread_title: US vs UK meaning

message: *I can confirm this is a US/UK language difference.  In the UK, an LPG-fuelled one is called a blowtorch but a kerosene-fuelled one is called a blowlamp. I agree the article needs a re-write. Biscuittin 21:40, 10 June 2007 (UTC)
thread_title:  Blowlamp 

message: *The article is a bit unclear about how old the tool has to be to be properly a "blowtorch" instead of a "cutting torch", etc., and I have no expertise at all, but I believe :Commons:Image:Old blowtorch 01.jpg would be an appropriate illustration. If someone more knowledgable agrees, please add it to the article. If not, then there are probably distinctions that should be made clearer. - Jmabel | Talk 06:42, 18 January 2008 (UTC)
replies: text: Not quite for the UK usage of blow torch, cylinders are various size, from the large H tanks you are thinking of to small tanks that only hold a few liters for small jobs and high portability. To an American, we find the term lamp curious, as in US view of the language, a lamp illuminates, an oxy-acetylene torch doesn't provide very much illumination, save when welding steel. THAT said, the image to the right is a blow torch in the US, a blow lamp in the UK.Wzrd1 (talk) 04:28, 29 February 2012 (UTC)
replies: text:  BTW, that's a petrol blowlamp in the picture, not a paraffin one.  These were more common in the US, relatively rare in Europe. Andy Dingley (talk) 16:35, 5 September 2012 (UTC)

message: * I have direct experience of using an older domestic type UK paraffin/kerosene type blow lamp/blow torch, having been shown how to operate one by my father as a boy, and being given the privilege of starting it up for him, ahead of it's use in domestic light soldering type plumbing repairs and similar. The main lamp body also acted as the main fuel tank (and, like most blow lamps), and this had a small dish shaped concave depression on the top, located underneath the burner assembly. The starting procedure involved first ensuring the tank was filled (but not completely) with paraffin/kerosene. The small depression was then filled with methylated spirits, which was ignited with a match or lighter (though I'm sure best practice would dictate use of a taper or similar for safety). The methylated spirits was allowed to burn until (I presume) sufficient paraffin/kerosene vapour pressure was available to to sustain the rate of fuel supply required for sustained burner operation (I don't recall how we knew when it was ready to go, but think the burner was lit when all the meths had been burned off). The burner was ignited by first closing a pressure relief valve and then operating the pump, which allowed the pressurised paraffin to be expelled via the burner, with a taper or match held at the burner outlet to ignite the paraffin vapour.
*:While writing this section I came across this good web source: http://medlem.spray.se/blowlamp/Function/function.htm which explains the different varieties of pump and their operation much better than I'm able to.Treagle (talk) 19:09, 25 January 2010 (UTC)
replies: text: I know why that small spirit flame was used, it warmed the upper assembly, where the upper part would now be called (at least, in the US) a generator tube, to vaporize the fuel before it departed the nozzle. The same principle is used in kerosene camp stoves and kerosene/gasoline lanterns still.Wzrd1 (talk) 04:30, 29 February 2012 (UTC)
thread_title: Operation

message: * I have never herd of the term "blow lamp"; I live in the UK and I have never seen any UK local shops or chain stores call them "blow lamps" only blow torches. I feel "Blow torch (USA) / Blow lamp (UK)" appeared to often in this article. I have made some minor changes and I hope they will be agreed with. 02:38, 7 April 2011 User:91.110.75.182
* I live in England. I was born in 1942. The first event that I remember was in the end of 1947. I have heard and seen this device called a blowlamp, and an oxy-gas torch called a blowtorch, countless times down the years. Anthony Appleyard (talk) 05:11, 7 April 2011 (UTC)
replies: text: True. As far as I have ever known - as an Englishman - a blow lamp is the device pictured within the article. It is used to melt solder/flux when joining pipe-work. A blow torch, however, is a much hotter, higher-powered tool which is used for cutting through metal. A blow lamp is not powerful enough to cut through anything. Therefore in the UK we make the difference between the two tools by giving them different names. In the USA, they just use the same word for both tools. EuroSong talk 15:27, 8 April 2011 (UTC)
replies: text: Not quite true, I live in the US and have never heard of an oxy-(various fuels, but most often acetylene) torch called a blow torch. I HAVE heard some refer to a propane torch as a blow torch, but that is fairly infrequent and typically used in the sense that what the UK English speakers would refer to as a blow lamp, as the propane units have replaced the old pump operated blow torch. England has only itself for the divergence of the language, as English wasn't documented as a language until after the Revolutionary War.  ;)  Wzrd1 (talk) 04:23, 29 February 2012 (UTC)
