I put this video together last summer, and never got around to posting a link on the site. Thought it would be helpful to know that you don't have to have oxy-acetylene for small silver solder ferrules.

I always liked silver soldering for tubing and smaller stuff, its relatively strong, easy and forgiving to do.
There are silver solders that melt at different temps. I always used a relatively higher temp one. I think it melts at about 1100 deg f.

In your video you got the stuff hotter than need be. What did you use for the solder? was it a pre-made ferrule with the solder already in it?
I've always added the solder as you would regular solder or a filler rod when gas welding.

Of course technically speaking when using melt temps of over 800F your silver brazing, and under 800 its silver soldering.
I always called it silver soldering cause of the filler material having lots of silver in it.

I had originally read armchair mechanics say it was impossible to so with one of them, so figures I'd try. Probably should have trying before buying the OA torch! Though it came in handy for a fridge repair a few weeks later. The silver solder is pre-formed and sits in the ferrule. I had one I bodged early on mixing up the flux flowing out for the solder, probably why ive been adding the extra heat.

I found the 56% silver is definitely the easiest to work with if not using the pre-formed rings. And the 3 sticks I have will last my lifetime.

We do some production work of this where I work.
We buy bags of preformed rings and use something called a Gasfluxer and a normal set of tanks with a small tip.
The gasfluxer contains liquid flux that gets mixed into the flame and turns it completely green.
When we train guys on the job the critical element to productivity is to train the small cone of heat that shows near the torch tip straight onto the part to be heated, no holding the torch an inch or two away.
