oxy-acetylene new tip

admin

i just got a new tip for my oxy-acetylene rig. it is a number 5 victor tip. i was wondering if anyone has any tips for lighting it, like sounds and cone length. i am semi-new to welding and am a little ashamed to say i am a little scared to light it. pictures would be cool too.
Reply:Oh sure...Make me move this from one thread to another.. Turn the oxygen on..Turn the accetlyne on..Slightly open the accetelyne knob on your torch..Light torch..Adjust accetlyne untill its burning good..Open oxygen knob slowley untill a nice blue flame happens..Then you can add or subtract accetlyne and oxygen at will..Play and have fun!...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:I don't agree with turning on the oxygen while you light a torch. All victor manuals that i have seen specify not to turn on the oxygen. It can potentially cause a flash back into the torch. When i light a torch I turn the acetylene on slightly, take my strike or an ignition source light the flame, ajust the acetylene until the black soot stops coming out of the torch, then i turn on the oxygen until i get a nutreal flame, if you hit the oxygen cutting jet lever and the flame does not change thats usually a sign of a nutreal flame. After that your good to cut away. --Gol'

Reply:when you say adjust the acetylene until the carbon stops, do you mean open it more so it sounds like its ripping air?i also need some cutting tips because i tried to cut a 1/8 inch wall of a pipe but i couldnt get it. pressures were 3psi acetylene and 15 psi oxygen
Reply:Turn your accetelyne up to 6-8 lbs..Try that and leave the oxy alone.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Just a personal opinion,but for cutting anything less than 3/8" I use a #1 or #0 tip. Unless your cutting some really thick stuff a #5 just wastes a lot of oxygen.                     MikeOl' Stonebreaker  "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw

Reply:i got a number 5 WELDING tip and i had a number 0 cutting tipwhat i said about the carbon is right then?

Reply:ok ill try all this tomorrow, cause its 10 o'clockthanks for all the help!
Reply:Originally Posted by Go1lum... I believe what you described was an equal pressure torch. so you should set both gases the same, probably around five.
Reply:do you mean 5 or 15
Reply:I say 25psi Oxygen, with minimum pre-heat to start,  once the cut starts, lead in to the cut, use the metal as fuel, so your not hanging around introducing unnecesary damaging preheat into the work.If you find a tip selection chart, and adjust your pressure, speeds and tip size accordingly, with practice, you will be able to make near perfect cuts.Search this site a bit, there are some in depth cutting threads, with pictures.Let's see some pics.Best luckLast edited by denrep; 10-31-2007 at 10:21 PM.

Reply:Originally Posted by SandyDepends on whether you are welding or cutting. The settings for the two processes are different. You're getting advice on both blended together here.
Reply:i was doing cutting wrong. i was reading up on it and i realized that i would turn the cutting tip oxy valve all the way open and using the torch handle to adjust the flame. im so excited to try it th right way, but i have school tomorrow. bah
Reply:For cutting, baizing or welding, turn the Acet on first a little, light it, open the valve till the flame stops smoking.  If it leaves the tip, back off a little.  One psi for tip # acet and double that for Oxy.  For cutting Start at 25 psi Oxy and go up from there.  I have used as much as 75 to cut 2" plate, but 25 will do 1/4 to 3/8.  If you set your acet around 8 to 10 and adjust with the valve, it will be fine for cutting and welding.David   Real world weldin.  When I grow up I want to be a tig weldor.
Reply:That # 5 tip is NOT the way to start off,that thing is gonna be roaring at the recommended settings.You do not lower the pressure to compensate for haveing to large a tip  Also if your using a mini set of tanks [10cf acet and 20cf oxy] you would be useing the acetylene at an dangerous output.Danger=more than 1/7th of tank capacity per hour  Drop down to a #1 and you will learn quickly and enjoy it more  And please read or download the victor manuel before you get to far ahead of yourself,some mistakes you can only make once!

Reply:im not really starting off because i have a number 0 and a number 3 tip.and im not using 10cf and 20cf, im using 40cf and 60cf i think. but the 40 im sure about.Last edited by catbed; 11-01-2007 at 10:49 PM.
Reply:catbed,apologies if i've mis-interpreted your origonal post, but base this on whats been said so farif you require the help of a welding forum to light an oxy-fuel torch then you will be far better off signing up for an evening class to learn how to use oxy-fuel safelyif the prospect of lighting the torch makes you nervous whats gonna happen if the torch backfires on you or you get a flashback?you have got flashback arresters and one way torch valves?
Reply:i can light a torch just fine. just unsure of a number 5 tip. i have flashback arrestors and i dont even flinch at torch pops.
Reply:it was the wording of the posts that bothered me. there's been several 'incidents' with oxy-fuel in my area over the past couple of years. in each case it transpired (after the exclusion zone was lifted) that the accident was caused by ignorance/improper use. fortunately no lives were lost but several properties were to say nothing of the neighbours that were evacuated from the exclusion zoneCatbed, a victor No. 5 tip is intended for welding 1/4"-1/2" steel. Are you really welding stuff that thick?Heck, here's a chart:As you can see the recommended settings are 6-12 psi on the oxygen and 5-8 psi on the acetylene.However, this is irrelevant because you SHOULD NOT attempt to run this tip with your current setup.If you look in the last set of columns on that chart, it lists the acetylene consumption for that tip in cubic feet per hour (SCFH). It list the consumption of a #5 tip at 15-35 SCFH. In order to comply with the 1/7th you would multiply that range by 7 to find the MINIMUM size of acetylene tank you should use. The minimum size tank you need for this tip is a 105-245 CF tank.Now, as for this: Originally Posted by catbedi dont even flinch at torch pops.

Reply:Now for a pop quiz (this is for catbed only, guys, so let catbed answer first). I'm sure it would help everyone (especially hotrodder and myself) sleep a little better if you can tell us the proper way to leak-check an oxy-fuel torch setup. This shouldn't be hard, it's basic torch safety...

Reply:Well I am sure someone here will say I am wrong, but here goes (and keep in mind I do this everyday and have for way too many years). I was taught to use a torch by the best torch hand I have ever seen and I have been looking for 40 years. I run my setup this way. Ten lbs on acetylene, never more than 12 except in extreme cases you will probably never get into. Acetylene is unstable at 15 psi and can go boom all by itself. I run 40 psi on my oxygen. This will cut anything from 20 ga to 3/4 inch stock. I use a double aught tip for everything up to 1/2" and sometimes use it on 3/4", yes I know what the charts and books say, but I also know what is tried and true. I also use the same psi for both when welding. With practice you can get just as clean a cut with an o/a torch as you can with a plasma cutter. When the tip is clean and the flame is set right you should hear a ripping sound out ahead of the flames (should sound like it is about a foot off your torch) with a Victor. I can't get my Harris to do this, but I think it is the cheap imitation tips they sell around here.About pops. If you are trying to weld and start getting pops turn your torch up. The pops mean it is getting too hot, and the gases are what cools it. You always shut acetylene off before shutting off oxygen. The oxygen blows it out and prevents backfiring. With large heating tips the torch will almost always pop when you shut it down, and when you get into the big rosebuds it's more like kablam!The difference between art and craft is the quality of the workmanship.
