In that case. Soldering. Hold the solder iron against the metal part to be soldered. After a sufficient amount of time, mate the solder against the metal part, NOT THE SOLDER IRON. Solder has flux in it to clean the metal being soldered. This melts, but heat it too much and it will burn. Don't inhale the fumes. Older solder has lead in, so try newer solder. Once the metal is hot enough, the solder will melt and 'flow'. Flow means it will flow over the metal to coat it evenly.
Do the same to the bare copper wires, heat wires, mate solder to the wires, and remove the iron once the solder flows.
Then take the wire to the metal. Heat the metal, and once you see both soldered parts 'flow', remove the solder iron. Practice on small disposable parts. Solder is NOT a mechanical bond, only an electrical bond. Ensure any parts bonded to the wire are fixed to something even if it is just zip tied.
Also get a solder sponge, a little water will help to clean the iron.
Good luck. Feel free to ask any questions, no question is stupid.
