Hi Peter,
it is a Victor style torch. I run Oxy Acetylene. Knowing me I probably just used the cutting tip in this case to heat the parts. I do have other, special brazing tips.
i found that I have to be patient and use low heat and let it soak into the metal. I also try to feed in the solder from an area opposite to the flame and draw it into the joint. Basically just like low temp soldering copper pipe.
