If you imagine soldering a tankard, you would use the highest for the side seam, the middle for the base, and the lowest for the handle. So you can chose the one most suitable for the job in hand. Generally called "Hard, Medium, and soft" although I have heard one called "Enamelling"

Agreed.
If you want to learn how to silver solder this book is good

And as others have said don't fool about with DIY store torches or small canisters that end up costing a fortune.
Buy a redundant oxy-acetylene set - a BOC Portapak is good. They are not expensive.  Acetylene is the expensive part so run it on oxy-propane using oxygen from Hobbyweld and propane from multiple places.
Great for brazing, silver soldering and heating up stuff that won't budge. The only downside is that you can't gas weld with oxy-propane, but if you are struggling with silver soldering I suppose that gas welding is still a fair way in the distance.

This seems to have lost them thousands of customers and opened the door for new competition who, like the schemes Stuart described, do exchange bottles with a refundable deposit. I could not function in my workshop without Oxy Acetylene bottles, so incredibly versatile and far better for welding panels than Mig, the only real failing is when welding particularly thick steel, then a cheap stick arc solves that problem. That said I have not yet found a job on an A7 that can't be done with Gas.
