What pressure settings for these oxy-acetylene torch tips?

admin

It's been so long since I've used our rosebud tip I've forgotten what oxygen and acetylene pressure settings to use.  And I usually guess at the others so I figured I'd "Ask the Experts" what typical settings would be for all of 'em and write 'em down for future reference...Koike torch (early 80's model) and torch tips:Tip.........Dia.............PSI1............0.029"..........__3............0.043"..........__7............0.063"..........__13..........0.082"..........__20..........0.096"..........__2000......0.043"..........__       <-- rosebud with eight (8) 0.043" Ø holesThanks in advance for your help!-jmcvo

Reply:Koike Aronson bought some of Airco and their tips are compatible. I've used Airco and Koike in the same torches with no problem.Koike/Airco/Concoa and clones are PLENTIFUL on Ebay, by the way.If yours does not look like this post a CLEAR picture of it: Attached Images
Reply:Unless I made an error 0.043 means a #57 drill size.  I seem to recall eight #55 holes in acetylene from one of my manuals was the max  you could go with the largest available tank without manifolding and breaking the 1/7 rule.  I think they called the largest tank 390 cubic feet.  Not what you asked but I will put that first.Close the oxygen open the acetylene a turn or so.  Screw in the pressure adjuster on the regulator, light the thing ovserve lots of black increase the output pressure until the black goes away,  You are close to the setting now for the acetylene perhaps go up another pound or two depending on your mood and what the number is.I would guess put the oxygen around 15 and start opening the knob on the torch.  Once you get a turn or two out and still not at neutral start turning the adjustment on the regulator until you reach neutral.  Same as before you are close add a bit more for good measuer if you are in the mood.The knobs on the torch work best when not in the 1/16 or so turn for adjustment which is what this will get you away from,In the event your torch is designed to use low pressure acetyle which probably is the exception but not an impossibility as I am not familiar with that brand or model I havn't given you real good advice.
Reply:Here's the info on Victor tips as far as rosebuds are concerned. Info is at the top right on pg 48 IIRC. It's not for your tips, but it should give you a starting point. Your fuel and O2 should be pretty close as far as pressures. Looks like the O2 is usually about 2 psi more than the acet. With a rosebud you need to have your acet pressure up fairly high compared to say cutting. Also as mentioned keep in mind even a small rosebud will quickly exceed the 1/7th rule on with drawl on most average cylinders. I think mine is a #6 ( though it might be a #4) and that's pushing it with a 75 cf acet cylinder. I only run it usually for maybe 2-3 minutes with such a small cylinder using the lower pressures. I've upgraded to propane for heating.http://thermadyne.com/IM_Uploads/Doc...__Sept2009.pdfHere's the koike cutting tip chart.http://www.koike.com/PDF/KoikeCuttingTipsCata.pdfAnd the Airco tip chart I located that has the rosebuds listed.http://www.stoodyind.com/Catalogs/FISC/05catpg107.pdf.No government ever voluntarily reduces itself in size.

Reply:DSW, farmall, and fran...k.,Thanks for your prompt, informative replies.  Lots of information to review and it seems as though I should be able to fill out the table but if I get stuck on anything I know where to ask!My cutting tips are similar to the pic farmall posted except there's an additional small step between the acetylene orifices and the final acetylene sealing taper as shown in the image below.Thanks again,-Jeff (jmcvo) Attached ImagesLast edited by jmcvo; 12-04-2011 at 11:41 PM.
Reply:I guess the others somehow could figure out you were talking cutting nozzles not single flame welding/heating heads.  Those nozzles are just like Airco/conocoa and there are so many series of them I would doubt without specifying which series at the top of the paper on your chart you might as well just use my technique for the fuel gas and set the oxygen for the thickness of material and number drill of the cutting orifice.Last edited by fran...k.; 12-05-2011 at 08:42 AM.

Reply:That tip will swap with Airco/Concoa/clones. It's the sealing surfaces that matter.Also, use one of these and you can play with Harris LP etc tips. I have one for my Oxweld, works fine.\http://www.atlweldingsupply.com/Airc..._474-3970.html
