I have a line on an oxycon that is not going to last. I spoke to the guy and he knows nothing about them but he does know it is a 5L
Is there anyway he can tell how many hours it has run for?
framerak

Does it have a counter on the back of it? What brand is it?
gemsinbloom
2010-02-03, 7:54pm
I just talked to him again.
Here is some more info. I need to move on this fast as it is DIRT CHEAP!
The name: Devilbiss
51A Series
He says it has 20 to 30 feet of hose
and then he said there is this number on it : 02324 , is that how many hours it has been used? If so, how does that compute? 2,324 hours?
gemsinbloom
2010-02-03, 7:54pm
This thing wont last , help please!
it's either 2324 or 232.4 - either way, that is a way low number. Did he say when they got it and if it was new when they got it?
gemsinbloom
2010-02-03, 8:03pm
It has fallen into his lap as some renters defaulted and left a storage room full of stuff.
Are you confident that number is the hours of usage?

if it is on the odometer-looking-thing, then yes, it is hours.
ask him how long it has been in the storage unit? and has he plugged it in?
low hours don't guarantee that the oxy purity is good, but it is likely. If it is that cheap, I would take the risk.
gemsinbloom
2010-02-03, 8:06pm
$100
how much do they want?
oh shit, I would at least go look at it. that is cheap.
gemsinbloom
2010-02-03, 8:06pm
yes he plugged it in and it runs. He does not know how long it was stored for though
The manual is there too.
ask him how long it has been in the storage unit? and has he plugged it in?
I paid $300 for an almost new one from Craigslist, taking the risk that it worked - and it did.
gemsinbloom
2010-02-03, 8:07pm
Oh he says it is a 2005, I dont get why it has so low hours then?
Are you sure those numbers are referring to hours?
Where are the numbers on these things usually?
gemsinbloom
2010-02-03, 8:08pm
He is asking $300, I got him down to a hundred
lol
and he will deliver it.
It is free money to him as he never purchased it
I paid $300 for an almost new one from Craigslist, taking the risk that it worked - and it did.
the manual being there probably means they got it new. good sign. You can also check the manual for the date of printing - should give an indication of age. You can also probably tell how old it is by the serial number.

hours - i've never heard of anything but hours.

2010-02-03, 8:09pm
I think its five years old. 2005
could be the person died right after they bought it - that was the case with mine.
gemsinbloom
2010-02-03, 8:09pm
Okay maybe I should call him and tell him its sold...

If your are really worried about it take your torch and propane with you and hook it up!

He is on his way to deliver it. crossing fingers, toes and ears
by the way, devilbisses come with a 5 year warranty, so it is probably still under warranty. If you have problems with it and if you can find someone local, you can have them check the purity for you and fix it if it isn't working.
gemsinbloom
2010-02-03, 8:39pm
Okay thanks for the info. I am very wary about driving out to a man's house on my own , especially at night so I am making him deliver it and having someone with me here to ensure I don't get murdered lol
I have not purchased anything from newpapers, craigslist etc for years.
paranoid much?

Ya, just too many crazy people out there these days. They use ads as a way to lure women.........many moons ago in Victoria when I had another business, this man who pretended to be a woman tried to get me to give him a lot of private info and then was caught stalking me. Police got involved. I have learned my lesson.
smart, not paranoid.

ID go for it $100 is a darn good deal. It probally has low hours and was in storage because someone had a family member that used it for a short time and they either passed away or no longer needed it they didnt know what to do with it so shoved it in storage. I say go for it.
gemsinbloom
2010-02-03, 9:08pm
Well I have it and it only has 2,000 hours and looks like new except for a sticker that was removed. It is a foreign piece of equipment to me so I really did not know what to check. Seems to power fine. When I turn it on, it makes a little noise, all lights come on and then two go off and two remain on. I should take a picture
I think I just got myself a sweetttttttttt deal........
So does my Carlisle mini c need a flashback?

Wow I have an oxycon.
wow, that is pristine - yep - you will see the numbers change as you use it - it will roll just like an odometer in a car.
what the serial number on it? I know on Airseps, the date of mfg is part of the serial number. Might be on a Devilbiss too.

One thing - when you run it, you should run it for a couple of hours. Don't do a lot of short term running. And you should run it at least once a week now that you have it. Believe it or not, it extends the life of the oxycon.

2010-02-03, 9:27pm
Great deal there ... that was like my one I had a few years back when I had my minor. You have the hose I presume too?
gemsinbloom
2010-02-03, 9:29pm
Okay so when I turn it on I can feel the air coming out of the valve thingy but its not coming out super strong. Is that normal?
It also came with some breathing hoses but I assume I just toss those.
Did the serial number tell you anything important?

save the hose in case you later get a 2nd and want to connect them. Throw away the cannula (the nose piece) if it is there.
No, that serial number isn't like the airseps, but it probably means something to people in the know :)

2010-02-03, 9:31pm
Gotcha. Well I almost paid $500 for the same thing and probably way more hours or traded my very nice freezer for an oxycon.
I feel very fortunate. Let's hope this sucker works as it should when I get the rest of the equipment. I am still not sure about needing a flashback thingy. Do I?
yes, that's normal. it's only 5 psi
no, you don't need flashback arrestors.

Is this because the oxygen and propane mix once they come out of the torch instead of together in the hoses? Is that what surface mix is?

I missed this message. Omg this thing is new then. They did not realize what they had then. Though he asked 300 and dropped two hundred in a minute. I think he just wanted some quick cash.

No regulator necessary either .. it delivers 5lpm that's it! You need one on the propane end of things though but I assume you already have that?
gemsinbloom
2010-02-03, 9:37pm
No , so far I only have the torch and oxycon. Buying piece by piece.
So you are saying normally you would need a regulator on the propane and oxycon but I only need one for the propane tank now since this is only a 5l?
Do you need a regulator for oxycons that are 10l and 15l?
No regulator necessary either .. it delivers 5lpm that's it! You need one on the propane end of things though but I assume you already have that?
You only use an oxy reg if you use an oxy tank. No oxycon uses a regulator. You don't need flashback arrestors because the torch is surface mix - a pre-mix (combustion happens inside the torch) would require flashback arrestors.
all you need now are hoses and a propane reg and you are ready.
gemsinbloom
2010-02-03, 9:57pm

Should have a filter that you can clean. Maybe a screw-type knob on the back and the filter is behind that. Kind of a foam piece that you can rinse out. Let it dry and then put it back on. Might help the dusty smell.

Two questions, how high should the oxycon be set? I use a pirannah and the directions that came with it states to set propane at .5 and oxy at 2.5. My flame doesnt' seem very hot. Do I need 2 oxycons? OK 3 questions, lol, under which catagory did you find the oxycon on C-list? I will be stalking them now. Pam

I use plastic hose from the hardware store with the right dimensions to fit the barb fitting on the mini? I forget did you get barbed or "b" connectors. But the propane Hose should be "T" grade which you can get at the welding stores. If you tell them that you are running a propane tank to a torch they will set you up with the "fixed" BBQ style regulator......

disconnect the hose from the oxycon, then set the oxycon to about 4.5 (2.5 is the recommended setting on a tank and is psi, not lpm) - then hook your hose back to the oxycon. Leave it there for ever and ever. Adjust oxy at the torch only.

I got a 10ml for $240 just like you did through CL. Mine was in an estate sale. :(
Most people that need them for their real intended purpose will not buy used so don't feel bad about the price. Mine had about 1500 hours on it and it is working like a champ.
I hooked my minor to NG and now I never haul tanks or worry about regulators.

Though when I turn the knob ( flow regulator?) the oxygen definitely speeds up but I don't see where there are actually figures for it.
immediately below the knob there is a tube with numbers painted on it. it should have a 5 at the top and a 1 or 0 at the bottom. Turn it so the bottom of the ball is at 4.5.

2010-02-04, 9:23am
No.........
But I went to turn it off and then a black ball finally showed up. It was way at the top and would slowly sink down once the system started to shut down. I think I am extremely overtired. The alarm went off again but I think that is because I took the hose off.
I guess I am half expecting this to be a lemon as I have had a lot of bad luck for awhile now.
Thanks Squid again

Found it lol
I guess it was not showing as I had the flow button turned all the way on.
192935
if the ball was all the way at the top, it was turned up too high which is why it alarmed. Turn it on again and turn it counter clockwise until the ball comes down to around 4 and then run it for a while.
don't hook it up to anything - just let it run.
gemsinbloom
2010-02-04, 9:36am
Oh well I just tried to hook it up to the torch. When I did , the alarm went off and the ball dropped down to zero. I did let it run for two hours last night with no issues. I will unhook it now and let it run again like you suggested.
So are these hookups okay or should I get proper hoses? Or is this a personal preference? Why would the alarm go off when I hook it up to the torch?
Pics say it all.
192936
192937
that is probably fine (but I would get another opinion on the hoses, just in case), but you have to make sure the oxy knob is OPEN when you have it hooked to the oxycon. The only time you ever turn it off (the torch oxy valve) is briefly to light the torch. You ALWAYS leave the oxycon running and the oxy valve on the torch open when you have them together and running.
If your oxy valve is closed and you hook it up, it will alarm.

You got an amazing deal. Those Devilbiss machines will chug along happily for 50,000 hours.
You do need both a flashback arrestor and a regulator for your propane, even though you have a surface mix torch. There is a thread about this somewhere. It convinced me to get the flashback arrestor.
Congrats. You are on your way!

Congratulations on your good find! A couple of things to keep in mind:
Never shut the torch off while the machine is running, except for the brief moment it takes to light your propane.
Never let it run above 5 LPM - as measured by the middle of the ball against the lines on the flow meter. You might want to set the flow with the oxygen valve on your torch all the way open. This sets an upper limit. Don't worry if you set it at 5 LPM and then while torching with a small flame, you look over and see that it is only at 2-3 LPM. That's normal. It's going to put out more when you let more through the torch while running a large flame and less when you are running a small flame. This is why you want to set an upper limit - because if you don't, it will allow more than 5 LPM out of the machine and that is bad for the machine.
Keep your line from the machine to the torch as short as possible - less than 12', 4-6' is great.
DeVilbisses like to be plugged into an outlet all by themselves. They do not share power strips well and if they sense they are not getting enough electricity, they will shut themselves down.
Keep your filter clean. Wash it every week or two - more if your studio is dusty.
Don't turn it off and on too quickly. What I mean by that is don't turn it off and then two minutes later turn it back on. Let it run continuously while you're torching. If you have to take a short break, just turn off your torch and open the oxygen valve back up and let the machine run.
Keep it protected from the elements. Don't store it where it gets super cold (like in the single digits) or super hot (over 100F).

Wow , conflicting opinions on this. What to do.....what to do......
if it would make you FEEL better, get one. I can't justify the expense when it isn't truly needed.

The whole flashback arrestor thing is like a spare tire. It's great to have it and not need it, but if you ever need it and don't have it...

Yes, of course you need a flashback arrestor (in your case for your propane only) ! Yes, you are running a surface mix torch so the torch will "probably" not cause a flashback, but what about all the other things life throws at you ? A cracked hose, a loose connection, a bit of hot glass melting thru the propane hose ? Those things probably won't happen either, but what if ?
Flashback arrestors are cheap insurance, and you only have to buy them once.
Search the safety forums on LE and elsewhere, get educated about the subject, then you'll be better prepared to decide if you want to run your torch without a flashback arrestor..

Okay you can be the princess then.
Thanks for all the info guys. I will be purchasing the "spare tire"
Safety always #1

FBAs are sold in pairs and I advocate using both if you are going to use them.
In all of the flashbacks I have heard of, the fire went up the oxygen line. There's a reason for that, but that's not to say that it would never go up the fuel line.
Your oxygen concentrator's not going to explode, but it could burn and you don't want that to happen.
Also, get the kind that go between the torch and the lines - not the ones meant to go on regulators. If there is a FB, you will want to save your lines. The claim that if you burn through your line, a FBA installed at the regulator will keep your tanks from exploding is not necessarily true. Many FBAs work on the action of a pressure wave from the little explosion of the FB triggering a valve to shut. If there is a rupture in the line, there won't be a wave of pressure to trigger that valve. Some FBAs are activated by the heat of the fire, but not all.
You need to keep your lines protected anyway and out of the way of any hot debris and don't let them drag on the ground and get roughed up too much.

WAIT!!
I use 2 devilbiss's to run my torch. They put out enough pressure (10psi) to use a flashback arrestor.
I love the peace of mind that the flashback arrestor gives me.
I have only had one flashback, when I was trying to run my national 3a underwater. It actually stayed lit until I adjusted the flame. Then BAM whizzzzzzzzzz propane off. You cant blow glass underwater.
Twenty five dollars to protect a $380 set of machines(in my case) is definitely worth it.
One thing, not to be a downer, but with a mini cc and bullseye, you will have to work slow and further out in the flame or you can scorch your whites and clears. If you can, keep an eye out for a second devilbiss like the one you got. A Mini cc on 2 concentrators ROCKS

Okay............we sure did pick an expensive hobby lol
Btw, I am so confused with the rest of the setup now with all the input, though I really appreciate all the help.
I went to the welding shop today and they confused it even more. If someone feels so inclined, please just give me a numbered list of what to buy exactly and I will do it tomorrow.
Enough waiting for this dream to come true...I can pay my power bill next week lol

Hi - just checked in again. Didn't get the pm - ?
My setup is really very simple.
Hose from oxycon to torch - as long as you get the pressure delivering at the torch, I don't see why the medical plastic tubing shouldn't be OK. Works for humans! Running it at top (5l/min) seems adequate.
Usual regulator on the propane, with flashback arrester between reg and hose. Hose attaches to torch.
And that's it!! Never had a problem.
Cheers

Thanks Robyn, I had forgotten to pm you. I am working to get funds for the rest of this set up. I am thinking I want to keep my hothead though so I believe I would need quick connects so I could switch back and forth, or?
