Eutectic tin/lead solder melts at 183 C, or about 362 F. Someone said they set their heat gun to 800 F...that seems *way* too high for any solder used for electronics, even eutectic ones that don't use lead...

Just sayin'...

Garmin has some really nice videos posted on You Tube demonstrating several methods of terminating and daisy chaining shielded wire.

That was me, maybe it was because it really was not at temp yet. It takes a little time to reach the set temp. Doesn't the sleeve temp rise asymptotically to the gas temp? It was taking a very long time and heating every thing else in the vicinity, it was not on a bench.

Sounds like some experimentation is in order to be sure ones specific gun is set correctly.

Just because the gun is set to 800f, don?t assume the solder is ever going to get that hot. Heat transfer will fall off drastically as the air gap increases... the. There is the insulating effect of the heat shrink...

I run my gun at 900deg F and it works great. Heat it long enough to get the solder to flow and your done. I also made a wrap around thing to put on the end of my heat gun that forces the hot air all around the heat shrink or the solder sleeve. Works even better!
