That’s right, and that’s where this is all going. How hot does the curcuit get, and what does solder do at that temperature? I looked it up yesterday. Solder melts at 300 something degrees F. What I’m seeing is that the circuit temp stays well below 300 F, unless ? Happens? What about AC versus DC? I was told that AC is not to be soldered, for this very reason. I saw yesterday that the AC circuit, the wall circuit, stays cool.
