Those numbers are indeed close to Acetylene but not as hot, as most sources put Acetylene at 6000+ F-example

200 to 400 deg or so does make a difference.


Again what about welding? That was the big question being asked in this thread since we already have good alternative cutting gasses.


So this stuff is right in the ball park with MAPP, at a little over 5300 F the MAPP is not quite as hot and just like MAPP what about welding? We already have easily available gasses for cutting so whats the big advantage to the home user here? I am not saying this gas will not find a home in industry and may be a viable alternative to replace Acetylene in some cases but we are talking home shop work here and I fail to see any big advantage over the easily obtainable and VERY cheap LP gas for cutting. I can certainly see where it would be a better cutting fuel in an industrial situation but again we are talking home shop here and even industrial cutting uses a heck of a lot of LP because of the huge cost advantage.


The reason I got a bit peeved is seeing the usual wild claims of "Hotter than Acetylene"! (It's obviously not) "outperforms Acetylene"! (but in what way?) Just be realistic and forget the fantastic claims, call it like it is, a decent replacement for Acetylene for some applications and produced from an environmentally friendly source. These are good attributes and are real pluses for this gas so why use mis-leading hype?
