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.

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
