Brazing

[granddad gnome]

I have been using a small brazing set as in the photo and have several bottles of the oxygen but have run out of the other. Can I use Propane as in the photo or not. If not can someone tell me where I can obtain the right gas please.

If you're not sure don't!!! Read the instructions or ask advice from the manufacturer. If you get it wrong, the consequences could be fatal

My guess is that the fuel is mapp gas, the yellow bottle is a giveaway (at least in the US). It is completly different than propane. Please follow Paul's advice. This is not something to be experimenting with.

STOP! DO NOT ATTEMPT TO FIT A STANDARD PROPANE BOTTLE!
As Paul and Phil say, this is not something to play with without expert advice.
Map gas is available in the UK.
The large propane bottles have a regulator to set the maximum pressure. You need to identify the pressure your little yellow bottle operates at, you then need to identify the fitting and thread the bottle uses. A mistake in either of these could be disastrous. This is before you even consider using a different type of fuel gas.
Generally Map gas burns slightly hotter than propane and is apparently less prone to spluttering.
Your yellow bottle should have all the info you need on it.
If it does turn out to be Map gas, both tool station and screwfix carry them.

Whoah! there is MAPP and apparently the link you showed has MAP-X gas...

My guess is he has MAPP .... but all he has to do is look on the cylinder.

Here in the states we have real MAPP and MAP-Pro..... the original MAPP is no longer produced apparently, and reports are that the MAP-Pro is not as hot.

Never heard of MAP gas, could be indigestion from reading a bad route?
