ok i know this has been asked and there are pics of set ups but i could not find it!
And I want to be certain this is correct before i strike the first match, so sorry to be a pain but is this ok an correct??! I have got the pipes on to the torch as far as I can but the propane metal grippy things are a bit funny! and don't seem to do a lot, maybe i have to squeeze them?

i can't see, your pictures are tiny
these look fine, just make sure that the hose claps have been tightened up snug... when they "squish" the tube slightly you are tight enough!!..
if you are really wanting to check - take a mug with water in it - add a few drops of washing up liquid and rub onto the joints of your propane hose with torch taps closed and your regulator open.. soapy bubble will indicate a leak of even the smallest amount.. on the oxy side, open the tap on the torch all the way and run your oxycon... although your are extremely unlikely to get bubbles on the hose joint here as all the gas will be heading out the torch...
DO NOT EVER RUN YOUR OXYCON WITH THE TAPS ON YOUR TORCH CLOSED!!!!....
the oxycon does not run when there is any kind of back pressure caused by closed taps on the torch.. and you will damage the unit.. this is stated all over the documentation, but we forgot a few times when we started and we warn everyone we can now!!..

I only seem to have a flash back and not a regulator in my stuff that arrived today. Do I need a regulator? Where can I get one if i do? (quickly)!
You 've got one Alice - hope you got my email thats the reg and Flashback in the pic !

yep thanks! I guess I just open it up as it has a max of 4 or 5 on it!
thanks.
My regulator doesnt have any numbers on it :-\
if you look underneath it it should be pre-set and the figure will be stamped into the metal somewhere... but to be perfectly honest, the propane pressure will not be a problem if you are running an oxycon.. the limiting flow will be the oxy... your torch will be perfect running on whatever pressure your regulator is set at!..
;D
what setting should the oxycon be on it has numbers 1-5 or 6 on the glass bubble thing! I think it should be 6 but wanted to check.
Mine is usually set to a little below 5.. say about 4.5.... if that's of any help ??
lpm, that is..
Les xx
mines also set at 4.5 ;D

Quinton i have been switching the oxy on, i light the gas first, then turn on oxy ???
this not right? i read in cindy jenkins book the "poop" propane oxygen, oxygen propane!
what should i be doing ::)
the POOP thing is exactly right - but the trick is not to stop the oxy for more than a split second while you light the propane.. once we have had a bit of practice we could flick the oxy off, light the propane and flick the oxygen back on.. i think it was mary that described it as a sort of breakdancing move with the added challenge of dodging flames!.. the trick is not to interupt the output from the oxycon for anything longer than the absolute minimum time.. the POOP also comes from bottled oxy, where everything is running at a much higher pressure like in a welders shop - not quite so critical in an oxycon setup..
once you have had a bit of practice, i think you'll find you know exactly how much to crack the propane open and will be able to light the torch without closing the oxy valve at all..
anyone else thoughts?..
ok....what about just turning both gas & oxy on and lighting them together? ::)
BANG !!!
LOL
more or less!!.. the only difficulty is that the oxycon normally takes about 5 minutes of running to get going and producing a stable flow of oxy...
our process is like this...
fully open oxy on torch...
turn oxycon on and go and boil the kettle for a cup of coffee/tea... make and drink coffee/tea
sit in front of torch and open regulator on propane cylinder...
light long wooden match, turn oxy closed and immediately crack propane open on torch and light, drop match, and with other hand open oxy again...
this breakdancing move results in a tiny interuption to the oxycon flow, and still fullfills the POOP rules... martin can probably give better technical advice here - but effectively the oxycon can be damaged after even a short period of running against a closed torch valve... we found a thread on LE a while ago which recommended the same process as we use - and some people don't ever turn their oxy off on the oxycon and just light the torch by cracking open the propane.. i think that the lower pressures of everything on an oxycon setup make this reasonably safe - but i would ever do this on a bottled oxy setup as the oxy is at a much higher pressure..
hope this helps and not confuses - anyone else with oxycon experience got any further info/comments/advice?
I do this - switch on my oxy-con, connect up my propane and start my kiln while I'm waiting. Then when I'm ready to start, I turn on my propane a tiny bit and light it without switching off the oxy. It goes POP! but I'm used to it. I always struggled to light the propane with my sparker, I burned myself several times, so it was safer for me to light it with the oxy on!
You'd need a strong cuppa after that ;D
LOL Les....what ya like LOL :D
you must have great nerves! I jump when the glass shocks! :)
Ok I think i may have a problem! When i turn the oxycon on it does not always bleep. Also the lights do not come on stright away. the normal with green light lights up then after a short while goes off, the one below which says Below normal then comes on. Why is this? is it the oxycon do i need to call martin?!
I'm not sure about using it when it is on below normal is it damaging it?
Thanks,
Alice.
is everybody still asleep!
not in belgium....
our oxycon always beeps when it turns on..... then shuts up after a few seconds...
check with martin..... or maybe mary will rise and shine for us shortly!!.. hang in there chap - it'll all semm like second nature soon, you just need to get through the start up phase where everything is new and explosive!!

Hi
Mine always beeps too. But I took delivery of it 2 weeks ago so am no expert.
The bleep is normal - to start withthen it shuts off ,but I should call him - its not the same as mine so I wouldnt like to say - I dont think the warning below normal is too much of an isuue because remember it was deigned for Medical use just perhaps means the oxygen isnt quite as pure - so in respect of damaging the machine i wouldnt worry but having said that its not right so give him a call - how frustrating .
Hope you get it sorted out soon Alice - if its any consilation mine didnt work when I first got it at all - !
These machines do not like being moved around .
Mine always beeps, it's the low-output warning, so that's normal till it gets going, but probably not a problem if it doesn't do it. Then it runs a bit on a green light, but changes to low oxy amber light mid session. It has done that since I got it a year ago, and it still runs fine!
that sounds like mine! fuh! i just left a message for martin, just to check.
Just tryed running oxycon on its own. It bleeped this morning! normal light went on after 5 min then stayed on normal for 10 mines then droped to the amber below normal light and flicked between the two for 5 mins then stoped and stayed at below normal amber light.
with reference to the flow gauge, should it always be left at 4 or 5 . or do i turn it up and down as i turn oxycon on and off?
Getting there slowly, off on bike now while weather not bad! then back to make beads and show friend how to!
Thanks,
Alice. :)
I never touch the regulator on the propane - its on what martin set it at.
I turn on the oxycon, open the propane valve, light just the propane at the torch then open the oxygen to setting 4.
to switch off I switch off the oxycon, close the propane valve, turn off the oxygen at the torch & let any remaining propane in the hose burn off, then close the tap.
leaving the oxycon running with a closed tap causes the oxycon to shut itself off.
leaving the oxycon running with the tap open without burning propane is very unsafe practice.
