Fire+Wire+Stripping=EASY

The fumes from the insulation around wires can't be good for your lungs, work in open area, avoid breathing fumes.
Unless you have fingers of steel, or like the look of a black smudge on you fingers, please were gloves, the tighter fitting the better.
Over time the lighter will heat up, careful where you put it down.

In this example I'm using speaker wire.
Snip the ends even with your dikes, or possibly sturdy scissors.

Pull Ends To Be Stripped Apart, a good 1/2 inch should be plenty.

Put on your gloves and simply burn the end you'd like stripped.
Burn for a 3 count.
Remember, hold away from your face. Please don't inhale the fumes.

Now immediately pull the insulation off the wire.
Repeat for all wires you need exposed.
If you'll be stripping lots of wires plan ahead for a safe place to put your lighter, it will get hot.

Now your all set.
Twist your wires together to bond them.
Insulate them with electrical tape, or an electrical nut.
