So, okay I've been doing some experimenting on my own to try and teach myself some skills. I have an old soldering gun and a wand and quite a bit of silver solder, some with a rosin core - I soldered the bare ends of a little copper wire together, no problem ( I think, it looks okay) but then I tried to solder the same bare wire to a copper pipe and it beaded up on the wire, or rolled right off.
I'm using flux, and touching the solder to the gun and letting it run right off,
What are the rules in general to hobby soldering? In this case, what should I be doing if I want to (eventually) run an LED light from a simple copper battery case? Anything would be helpful, I'm learning!
This is the gun I have,
not this brand , but basically the same thing with the light in front
and one of my dads old soldering wands from way back when.
thanks for any help!
