In the lighters 2, once the pressurized fuel 14 is used up there is no pressure to force liquid 18 in line 24. However, the volumes of fuel 14 and liquid 18 are computed so that fuel 14 will be exhausted while bag 20 still contains about 2-5% liquid 18. Thus, throughout its life it will continue to operate as a colored flame lighter.
Hi, Iu've just bought an economic torch lighter. It looks nice, but like the most torch lighters, it has a little metal piece at the base of the flame, that makes the flame colored (violet in my case). For example, copper is used to make the flame green.Now I am wondering if there are some health issues by inhaling this ="coloreda" heat, or maybe the high temps burn all the possible toxic vapors?Thanks
