Solder a solder copper piece first (the stranded wire has a tendency to 'fan out' to nearby wires), using all of the fore-mentioned techniques Drill a hole in the trace with a dremel, put tinned wired in there, apply heat to wire a bit away from the trace until tin starts to flow. via
What kind of solder do you use for copper wire?
The best solder to use for tinning stranded copper wire is electrical-grade rosin-core solder. This is an acid-free solder that contains a flux in the core of the solder. Never use solder that contains acid, which can damage the wire or its insulation. Acid-core solder is intended for use in plumbing applications. via
Can copper wire be soldered together?
Because the soldering iron is extremely hot, don't lay it down while you are looking for the next part to solder. You can buy a soldering kit, which includes a soldering gun and base, sponge and solder, which will generally be tin or silver and work fine with copper. via
Do you need flux to solder copper wire?
Strong metals such as brass and copper will require a synthetic acid flux in order to be soldered. This will remove not only oxidation but also corrosion and other residues that build up on these metals. via

What solder do plumbers use?
Acid core solders are most often used in plumbing applications to join metal pipes or sheet metal. Rosin core solder is also fabricated with a hollow core inside the solder wire, but the flux used is a milder variety made of rosin, which is a solid form of resin derived from conifers such as pine. via
How do you solder copper wire with a torch? (video)
Can you solder silver and copper wire together?
A simple way of soldering together a piece of copper and a piece of silver is to use a technique called sweat soldering. Now, with a small amount of easy silver solder coated in flux and placed at the very end of some fine tweezers, you can begin to heat it with your hand torch. via

Can I use lemon juice as flux?
Cut six lemons in half with a kitchen knife. Squeeze the juice from a lemon into the strainer. Stir the juice in the container for 10 seconds with the wooden spoon. The citric acid flux you have made can now be used to prepare metal for soldering. via
What is the best way to solder two wires together? (video)
Why won't copper fittings sweat together?
You need to heat the copper to point where it is hot enough to melt the solder. I've had problems using propane torches for this purpose, so bought a Mapp torch. Makes all the difference. Another thing that will impede the heating of the copper pipe is any kind of moisture in the pipe. via
Does just for copper work?
5.0 out of 5 starsIt works and is easy to use. This product works for pressures within copper piping as advertised. For water normally 60psi and have seen 125psi for air. It holds very well. via
