Who is making their own o2 ?
do you find the quality as good ?

short answer is yes. long answer is there is multiple ways to go about it. search o2 generators and read the homefill threads also.

you dont need to act like that someone new to the industry might not have any idea what good search terms are. if you dont have anything constructive to add just dont type its not to hard.

o and while the purity is ok i did notice a difference when using a homefill style unit to fill/create your own o2. not sure if the higher end industrial machines work the same or not. i use a bit more o2 to get the same type of results as opposed to tanked o2.

The not-too-complicated answer is that when your oxygen concentrator starts getting worn and the compressor is putting out low PSI to the sieve beds, you will notice a difference in the glass you blow - namely that work-related devitrification is increased - devit forms more rapidly and becomes harder to remove when the purity of O2 is low. Rebuilding the compressor generally solves the issue, and above 90% concentration it becomes hard to tell between bottled and concentrated.

Edit to clarify:
This is from my own personal experience concentrating oxygen with an Invacare PlatXL 5lpm and a SeQual Integra 10, pumped into a 60 gallon reserve tank at 100psi by a Gast compressor. The Integra lost compressor pressure due to worn piston cups and a leak from the cooling coil, upon which work related devit was noticeably increased with all types of glass used (especially devit prone colors like china black). Rebuilding the compressor of this unit solved those problems, and tests I performed using the concentrated oxy versus liquid and bottled yielded the same results. Bottled oxy was on a CC at a friend's place, so I didn't have the Minor riding the CC+ with which to apply colors in quantity. Using stringers of English Ivy and Black Lightning yielded the same results in color when encased, however, and silver fume was the same at both locations as well.

ive been using tanks side by side one after the other its a noticeable difference. ive been on the same torch and regulator setup for over a decade now. so i know very well exactly what everything feels like on my set up. its a difference not a deal breaker. i never have devit problems regardless,most devit is either manual devit or devit from over working the chemicals out of the glass. its more how it effects colors i use a highly oxidizing flame on,to stop colors from reducing.

Ah, I could see there being a noticeable difference with sensitive colors... I've gotten used to encasing the hell out of everything to prevent that on the premix torch anyway so it's harder to tell. So you notice sensitive colors reduce more easily on a concentrator that's running normally, then? Or it's harder to achieve flames oxidizing enough to prevent that from happening?

It is actually terribly hard not to type something sometimes...

..I'll refrain since you seem to have this one under your control.

I find that the Homefill oxygen cylinders versus purchased from airgas tanks there is a difference... The oxy is for sure less pure than airgas oxygen, and you will burn through a little more a little faster from a homefilled tank. The flame isnt as crisp, but its really damn close. GOod luck

He actually just bought one of my systems that I am sending out shortly. I think he just wanted to know what other people experienced with them. I talked to the guy and he def isnt a complete noob or anything like that.

technically no one is making their own oxy... just separating it from all the other elements in our air. :nerd:

I bet there is some crazy bastard out there making it making his own hydrogen from water. But I guess you could still call that not making oxygen since you are seperating it from water.

wow i came on here for information and comraudery....
Not to be treated like a special needs kid.

I do not need info from know it all people like you..:tongue2:
BTW ...i own a computer store and am very savy on the use of a search engine...

I searched the web for you so you would know the definition of a "Forum"

forum-
1.

a meeting or assembly for the open discussion of subjects of public interest



2.

a medium for open discussion, such as a magazine



3.

a public meeting place for open discussion


Wow 2 of the definition talk about an open discussion....not get lost and look it up on your own...

I lika to ask a lot of questions and want current info..
A lot of what is on the posts is old info..

I want up to date info from people on "current" poients of view..

Plese do not reply to my posts if you do not want to be helpfull..

Remember you either needed help at some time or will in the future...dont be such an a$$..

On that note thank all of the rest of you for being helpfull...

I will let you all know my results..

Lampworkers are a tight group. Well were, YouTube killed it. Do this for 10-15 years straight and you will have the respect your asking for. Until then suck it up.

Btw this is coming from someone who is not in that group. Lol

15 years in here been part of the forum since the beginning. as tight as we are people just need to relax no reason to be rude just for the sake of being rude. we've all had questions,thankfully know adays theres people to answer them and sharing actually happens. when i started people would turn off the torch when you entered their studio and sharing was rare/ people should be happy we have a resource that we can all learn from.

Bringing back to the original question- I've filled about 3 tanks so far, and it seems that I go through them WAY faster than when I bought them from the welding supply. I'm running a Homefill with under 500 hours, and an Invacare Platinum X with about 11,000 hours.

I could be wrong, as I usually ran off liquid so I'm a little hazy about how fast I used to kill a K-tank, but it really seems like these are not lasting as long. Today in my shop I didn't use my Mirage once, I worked solely on my smith little torch, running a small flame at that, and I used well over 250 cf in hours! Yesterday I ran my mirage for probably an hour, and the Smith little torch the rest of the day, and used almost 1,000 cf! That was something like a 7 hour day.

Anyone else notice this? Does it mean I'm getting poor purity? Or . . . ?

I'm going to double check for leaks when I go in tomorrow. But my intuition says that this is not the problem.

i would think cleaner or not you would use the same... as the regulator still allows the same amount of whateverthefuck is in there out. for me i know i go through it faster, because i dont give a fuck about burning through a bottle!

its awesome. especially for a newb, you might as well get into next to free oxy. someday when your done wasting tons of it to learn you may want to switch to something else

No, if it's is less pure you'll use it faster, SillyOlButt. Of course the same volume flows at a given torch setting, but more than likely you would be concentrating on the results on the glass. With lower purity O2, one would pick higher oxy knob settings to make the same things happen.

Are you sure you are not talking about PSI? Isn't a K tank only 282cf total?

Can a smith little torch even use a K tank in a week?

Your Homefill wont fill the tanks if your o2 purity is below 95%. Ergo, your most deviation from a standard tank is 3% and vs liquid is 5%.

Red Max K tank lasts me about 10 hours
Mirage K tank lasts me about 6-7 hours
Smith Little Torch lasts me about 300 years =)

its 92% not 95%


im sure he meant psi mecha :)


if your used to liquid its definitely less pure. between 5%-8%


like i said not a deal breaker just have to adjust things a bit to compensate for it.

Oops, yes I mean psi. Sorry, long day.

And actually you're both wrong, it's >90% purity. Here is a PDF of the manual-

Yeah, I would guess 300 years for the smith torch too. I was shocked I had made any noticeable dent. I'm hoping there's a leak...
