Very fast, and a really hot-sounding flame. Looks like there is a gas fluxer involved too, as the flame is green there as well. Interesting point of technique - looks as if he gets the whole area he wants brazed right up to temperature (that's a pretty bright orange glow) and then adds all the brass almost in one shot. Obviously works, but a bit different from what I learned with Dave Yates, which was more like whole area up close to temperature (dull glow if any) and add brass under heating, then use the flame to lead the molten brass just where you want it (it follows the combination of heat and flux).
