Re: Extending wires
Yes, Resin Core
There are several ways to Solder together,
For a Straight Butt Splice,
I strip back Equal Lengths,
Slide my Shrink Tubing over,
then Shove the 2 ends together Past each End of the Wire, so your Splice is about 1/3 shorter - kind of woven into each other.
Then I twist the splice in Opposite directions so it holds itself together and Solder.
Let Cool, if you try and slide the Shrink Tubing over too soon, it will shrink and not allow you to move it into place.
There are times you are adding a Softer Wire to a Stiffer Wire, you can Wrap the Softer one around the Stiffer one.
You might want to add a Feed - Midway, I will splice in by cutting the Insulation thru with a Wire Stripper about 1/2" apart, Slice between both Cuts Length wise and remove Insulation, now you have the Bare wire Strands, Insert thru with the End of the Stripped Wire you are adding and Wrap around, Solder and Tape.
If the Wire is close enough to a Terminal in a Plug, you can Un Pin and slide Shrink Tubing or they have Shrink Wrap Tape.
