I wonder if you can hand-solder SOJ if you start by putting solder

I've done this with a hot-air pencil. I find it a bit easier than doing SOJs with an iron and wire solder.

Do you have to control the temperature of a small tube hot air source to keep it from being too hot, or is it just always hot enough to do damage and you take off the heat when you see melting to avoid damage?

I have an unregulated air heater intended for plastic welding, and I imagine it could work somewhat with a variac controlling it's heat input, and pressure regulator and trial and error to find settings.

How do the kinds Pace and others make work? Do they have a hot box with quick FB control on it's temp, and go from zero flow to preset flow when you want heat?
