Pro Flame?

admin

Man am I glad I found this site.  I've been looking over & through these boards since I found it yesterday.  (Not real productive for my 8-5 job..  )Has anyone used Pro Flame?  http://www.etox.com/proflame.htmMy question is, are there limited uses w/ Pro Flame, such as strictly for cutting?  I think the guy at etox asked if I was going to do any brazing, which I said "prolly not" & he showed me a brocure on this.  It sounds pretty good & especially for cutting.  But, I'd like to be sure I could do some light OA, or OP (help me w/ the correctness if I need it) welding if the need should arrise.  Thanks for all your help.  ..Stephen
Reply:It is my understanding that the oxygen is what really does the cutting. The other gas is used to initiate the flame and keep it going, the fuel. It might be wrong, but this is what I remember from the oxy/acet. class I took. What is the price difference over acetalyne?
Reply:I think it's around $35 for the pro flame, but I'm not real sure what size that is.  On an equivalent basis this is suposed to outlast acet 7 to 1.  In the long run its cheaper.  You do have to get propane tips for the torch.  Just wunder'n if anyone else has used it & what they think about it.  Also if they use it in all the same ways you would use OA.
Reply:Ok, from reading up a little more around here & other places this is one of those local/regional propane mix deals.  So I know "PRO FLAME" will burn hotter then Acetylene, but being propane based, won't it also use more oxygen?  I need some thoughts on this & these type mixes that apparently each region of the country has.  My use will be general cutting, heating for bending of plate, roundbar etc. & possibly some oxy/fuel welding.  General Farm use, building pens, repairs & other projects & work for other people as I can find it (that I fill comfortable with doing given my skills).  Stuff that's not necessiarily being used everyday, but will get a good workout at some times.  Talk to me fella's.. give me some input.  If you suggest a particular fuel, give me some reasons for why it is better than another option or why you like it or use it above something else.  Thanks, S
Reply:For heating/cutting, you're probably better off with propane.  The two big downfalls from what I see, is that it's a pain in the butt to use in any sort of wind, and its substantially slower IMO.  It can produce very clean cuts, but you have to preheat the heck out of your cut, and use slower travel speeds.  It should not use any more oxygen than acetylene does when set up properly, and you're correct, the oxygen stream is what does the cutting.  You can actually heat up the metal to a molten state, extinguish your flame, and still make a cut using just the oxygen stream.Also, forget the use of propane for welding.  Just isn't hot enough to do the job.  Here I prefer acetylene bigtime.  I was taught to weld OF using it, and you can make it look like a TIG weld with some practice.
