Default Oxygen cylinder for a mini 'welding' torch?

Not sure where to ask this so thought I'd start here .........

Note: I'm in the UK

My father is a jeweller and has had a kind of mini welding torch for
some years for doing very fine welding work on jewellery (the torch is
a 'Micro-Torch' by Formadent, France).

He has though just found out that he can no longer get hold of new
oxygen cylinders from his usual supplier.

The oxygen cylinders he currently has are labelled:

Prodont-Holliger SA
06140 VENCE FRANCE

and have a brass screw thread

they are 74mm in diameter and 265mm in length

I've done a search on the 'net but can't find anything, not even the
company referred to.

As an alternative, can he get the existing cylinders refilled?

The welding torch uses two oxygen cylinders and one gas cylinder (the
latter is much smaller than the former and has Miniflam written on
it).

Any thoughts or ideas please?


Ta,
Phil

I not sure if this is useful to you but I use an oxy/propane setup from a
company called MicroFlame. The oxygen bottle is about 90mmx300mm and can,
theoretically, be refilled at most British Oxygen depots (they are not too
keen to do it though), or can be filled from any standard O2 bottle via an
optional umbilical cord, also available from MicroFlame. I've had it for
about 25 years but am pretty certain that MicroFlame still exist - in Diss,
Norfolk, I believe.
I hope this helps.

Maybe someone over at
sci.engr.joining.welding
would know more about this one...
There are some people there that know some
really arcane things.

My best guess is that you might be able to salvage the torch itself by
fitting it to oxygen and propane/acetylene bottles and regulators from
the states. If it's old, the ring gaskets in the torch itself will
have to be replaced, and those may be hard to find. Fitting of a
standard hose to the torch may be a bit of a trick, too.

Is a hundred bucks for a new Smith Micro Torch balance with a couple
of days of your time doing hardware hacking?

Thanks for the suggestions so far. A few more suppliers have been
approached and questions asked based on suggestions here but still no
luck. :-(

Oh dear, loks like he'll have to re-invest in a new torch (which
seems ridiculous, but that's life I guess).

Why don't you buy a standard O2 tank at a welding gas supplier, that
they specifically tell you that you can drop off when empty and pick up
a full replacement. The initial tank cost should be about $30-$40, and
refills very cheap.

This is how we do it in the US. The odd fittings on the smallest tanks
can be trouble. Which is why you should get something standard.

Now the next task is adapting the new tank to your existing hardware,
which with a little ingenuity you can do for far less money than buying
a new torch. Perhaps the welding gas supplier can make the adaptations
for you, if you're not into that sort of thing.

Good day!

Hi Phil,
I just moved my torch and tanks to my new / old studeo
I have a Smith Little torch with a preset regulator for disposable
propane and a adjustable regulator with a refillable 40 cu. ft. Oxygen
tank.
I like it as it is much like what I was trained on.
likely cost total would be
$ 100 little torch for Propane tips # 3 - 7 lasts indefinately
$ 40 fixed regulator for disposable 14 oz propane tanks lasts
indefinately
$ 3 / 2 tanks at Wallmart or K mart.
$ 65 for Ox regulator will last indefinately
$ 100 for refillable Oxygen tank purchased locally lasts indefinately
$ 20 for Oxygen tank refill lasts for 3 to 9 months.
$ 330 for a professional system which will do most all bench jewelry
tasks.

The advantage of using disposable tanks is that it will meet virtually
all fire codes and insurance requirements.

A way of saving some money is to purchase a small Oxy Acetylene smith
torch setup ( Torch, Regulators and Hose and use the Acetylene
regulator for a Smith Air Acetylene torch.
I do not have the Air Acetylene torch, but it is on my to buy list for
Silver Smithing.

An additional benefit is that for casting, you will have a Oxy
Acetylene torch.

This is not a cheap setup. It is professional and over the years will
prove to be the most economical however.
