Try this. There will be lots of others.

Might need more heat, but not hotter.

The problem with acetylene is twofold from an insurance viewpoint

1- It burns at at least 2500 centigrade which is pretty amazing

2- It's ignition lower and upper flashpoint goes from 2.5% to 95%, so if you get any sort of leak it's going to ignite

So it's hairy stuff to have lying about

I have had no regrets from moving from acetylene to propane. I changed the handset but some people don't even bother doing that!

Same could be said for 47kg propane bottles which all up are just under 100kg

Oxy Acetylene is a hotter flame than Oxy Propane

About the only thing that Oxy Acetylene is necessary for is Oxy welding. You won't get a hot enough flame when using welding.

If you want to cut, braze including silver brazing then Propane is good. Propane is also more economical to use.

I use a rent free oxy bottle for my oxy propane set-up, in the long run I believe it will be more economical and would recommend giving this consideration. You pay a refundable deposit on the bottle, a oxy refill costs around £35 for a 9 litre bottle. My local auto spares supplies rent free welding gas and oxy. For hobby use you can expect one 9 or 10 litre oxy bottle to last a considerable length of time, after 1 year or so I've used 1/4 bottle. I mostly use my oxy propane for small fabrications and hot metal forming but have used it alongside a propane torch to silver solder a copper vertical boiler.

I did have an oxy propane set using disposable cylinders but found it too expensive to use regularly, this was some time ago though.

I beleive the hoses should be changes as there is something in Propane that can attack the lining of Acetylene hose so get an orange hose not red.

Brian,

I use Oxy/Propane with standard nozzles and also a big heating torch but it requires a different regulator. For welding steel, I use Mig, Tig or stick.

Excuse my ignorance and I dont want to get off track but can someone explain MAPP gas and if it has uses in the model workshop..?

Will do Keith, just thought maybe some are using it and have personal experience of it.

A few years ago bought a MAPP gas torch and cartridge from Axminster, it was a good bit of kit, when the cartridge ran out tried Axminster for a replacement and they had discontinued MAPP gas. Have not been able to obtain a replacement cartridge since, manufacturer was French perhaps they have something against the British and refuse to sell to us? Also have not seen true MAPP gas available since.
