Strip off 1" or better, get a real good twist with a GOOD pair of

soldered wire showing and tape well.

It would appear that cutting back the wires after soldering would
violate NEC 110.14(B): "Soldered splices shall first be spliced or
joined so as to be mechanically and electrically secure without solder
and then be soldered."

Also, NEC 250.148(E) prohibits relying on solder for the grounding
conductor (EGC): "Connections depending solely on solder shall not be
used."
