victor super ranger 2 kit

admin

hi,first off:#1 no, I'm not pyroracing85! #2 I did read the book that came with the kit.#3 I can torch cut OK.   not well,  but OK.my question regarding acetelyne use....  and my victor super ranger 2 kitsee, it doesnt have a flow meter, so I really dont know what the heck I am drawing off.I have a 80cuft (i'm guessing),  acetelyne bottle.   I was just reading about the draw rate and such in pyro's thread, and people said that 80cuft is a small bottle and not suitable for any rosebuds, and only the smaler tips.are the tips that came with my super ranger ...Torch handle - 100FC, Welding nozzle - (W-1) 2, Cutting attachment - CA1350, Cutting tip - 0-3-101, suitable for my draw rate?and, I did buy a rosebud.  but I use it probably way below potential.thanks.
Reply:Your acetylene regulator should have two gauges, one registers the psi of the gas in the bottle, one registers the psi of the gas to your torch. I'm not sure what you're calling the draw rate? @ 5-7 psi acetylene to your torch, I'm thinking this is what you're calling draw rate? Your torch being the 100FC is a small torch when compared to the Journeyman. Your cutting tip is an "0" and is fine for 1/4" and thinner, with experience you can cut much heavier with it too. Your rosebud will be the small version too and shouldn't be a problem with that small bottle, except it uses gas up quickly!Only when the last tree has died and the last river has been poisoned and the last fish has been caught will we realize we cannot eat money.                                         -Cree Indian ProverbSA 200 LincolnVictor Torches
Reply:lets say your cutting tip uses 6 scfh of acetylene for cutting preheating. thats6/80 of the tank so you are well under the 1/7 guideline. lets say a rosebud uses 25 scfh for heating.. thats almost 1/3 of the t tank ..expect problem..
Reply:There is no rosebud that will connect to your welding handle (100C) that will give you trouble free use with an 80 cuft acetylene bottle. There has been much discussion about this subject on this thread, but let me see if I can clarify the issue for you.There are two things to think about when using ox/ace torch, or cutting equipment for that matter.1- What is the correct gas pressure for the oxygen and acetylene for the tip being used?   Always look at the manufacturer' tip chart for these pressures.   Your #0-3-101 should be set at 3/8" plate 25-30 psi ox and 3-5 acetylene                                                1/2" plate 30-35 psi ox and 3-6 acetyleneWhen lighting the torch the acetylene flame should burn of the tip, meaning there is a gap between the visable flame and end of the tip.2- How much gas is being used by the flame? The draw rate.For years manufacturers of cutting a welding equipment, have recommended not withdrawing more that 1/7 of an acetylene tanks capcity an hour.  Your 80 cuft tank would be 11.5 cuft/hr.The CGA (cylinder gas association) uses 1/10, and Air Products (a manufacturer of acetylene) says 1/15 of a cylinders capcity for continual use.These warnings are in place because of the speed at which acetylene burns and the way it is stored in your cylinder.   The acetylene cylinder has a sponge type material in it and is filled with acetone.  The actylene attaches to the acetone as the tank is filled, and is released when the tank is emptied.  This process is very slow however. Thus, the 1/7 rule.  All of this done because acetylene is very unstable at 22psi and above in a free state.  (you will not find an acetylene regulator that will delivery more than 15psi for this reason)  Not only does the gas release from the acetone slow, but acetylene burns very rapidly.  So if you do not have enough acetylene coming out of your tip from your tank, the flame will burn back to the mixer of the tip and pop off with a very loud bang, sounds like a firecracker going off.  If your torch burns back and pops of you do not have enough gas in your tank to use that tip.  This can happen with any size tip, but most with rosebuds becuase of the high draw rates of rosebuds.  If this happens stop and change to a new cylinder or a big one.  (Or you could just keep relighting it and have to send to someone like me to repair it after the mixers burned complete up.)Some times I hear this statement " will I have been using a rosebud this way for years and never had a problem" .  The reason they have used it before and it worked is because an acetylene cylinder will build up a  little head volume if not used continually, which will allow a rosebud to run for a little while without any problem. But get it on a big heating job and run it for more than a few minutes and it will burn back if your tank is not big enough to handle the draw rate.I say all that to tell you my standard for using rosebuds and determining draw rates, ( mine is the same as Victor).  Use only 1/7 of the tanks CONTENT per hour.  It has been stated that there is no way to know how much gas is in a cylinder because pressure can change alot with temperture changes.  That is true, and that is why I will always use a full cylinder of acetylene with at least 10 times the withdraw rate of my tip before I would start any job.Withdrawn rate can be found in all major manufacturers' material and user guides.Hope this helps!OAdoctorwww.regulatortorchrepair.com
Reply:im sorry i may have mis-quoted my torch sizes.  I'm away from them so i looked up the set i thought I had online.I will correct my facts ASAP.
Reply:well I was correct about the models.  matches the #'s stamped on my stuff.I have a "6 WFA 1" #6 rosebud.   I understand it consumes too much this is unfortunate.  your description, of course exactly matches my experience with the short duration use.  I have been using the same bottle for several years now, so that gives you an indication of how often I use it!   I only use the rosebud to heat up triggers and sears which I oil quench to harden. no problem there.   and that very short usage time made it impossible for me to estimate my consumption rate........ until I used it to heat a tube to bend and forge the end for a project.   that's when I ran into the burn back problem.thanks very much.
Reply:Get a larger bottle, or go to a small forge.It is not hard to make a small single burner forge from an old propane bottle, and a stand from some surplus tubing.The only hard part may be finding the right burner.Anyhow their are plenty of posts on small forges....
