Q: Do you crimp these or just twist the wires together and heat shrink them? if no crimping, how strong is it compared to crimping and heat shrinking?

You will just need to twist the wires together and heat shrink them. Solder inside the connector will melt and bond the wires together. The connection is almost as strong as crimping and heat shrinking. When heat is applied, polyolefin tubing reduces in size and adhesive flows inside the insulation, creating a strong seal

Q: Will these work for solid wire rather than stranded?

I tried to use these when I put a brake controller on my SUV. I used UF underground solid wire ad it did not work too well. The heat shrink started to melt away before the solder would stick to the solid wire, it seemed to solder the stranded wire very nicely. I soldered the wires together and then slid the heat shrink butt connector over it .Just as a side note, I bought the heat gun fro HF and it did the job.

Q: I can't get the solder to melt before the heat shrink tubing starts to burn. i am using a wagner heat gun. am i doing something wrong?

The heat gun you have sounds like a paint stripping heat gun. There is a heat gun available in harbor frieght that has 12 settings #'s 97114 or 69343 that is better suited for the task. Or you need to keep the heat gun further away and moving across the wires while you heat it.
