1. Solder is used as a kind of glue to hold pieces of metal together and conduct electricity and heat between them.
2. To do this, you need to apply a metal that has a melting point lower than any of the metals being joined, else they will melt first.
3. For almost all electrical work, we could use lead, which is very cheap, but melts at about 328C (622F). Tin is expensive, but melts much more easily, at 232C (450F).
4. If we mix tin and lead together, we get an alloy which melts even more easily. It turns out that 60% tin and 40% alloy (60/40), like this solder, melts at 188C (370F). Even better, but more expensive and hard to find, is 63% tin and 37% lead, which melts at about 183C (361F). Plumbers use 50% tin and 50% lead alloy, melting at about 214C (418ºF). Avoid it for electrical/electronic work.
5. To get a good solder joint, the parts to be joined MUST be clean! Use a wire brush or sandpaper (not steel wool, bits of which can drop on your work and create short circuits.
6. Wrap the CLEAN wires together or clamp your CLEAN work so it will not move after you remove the soldering iron. Press the hot iron against the joint and touch the solder wire to the iron tip where it contacts the joint. Let a very small amount of solder melt and get drawn into the joint to help heat to travel into the joint. Then touch the solder to the part being soldered. To get a good joint, the JOINT, NOT THE IRON must melt the solder. The solder MUST "wet" the joint and flow into the joint smoothly.Read more ›
This solder roll is the 31604 which is the thicker wire one. If you prefer a thinner wire, simply buy the 31605 roll. Except for the wire thickness, they're exactly the same. Both are 4 ounces, so you get the same amount of solder. Both are 60% tin and 40% lead, so you get the same percentage.
For some reason, most people buy this thicker wire 31604 here at Amazon. I prefer and recommend the thinner wire 31605 because you can use it for large and small projects. With this thicker 31604, you tend to apply too much solder in small projects.

It's been awhile since I've had to buy solder, and I bought this mainly on the strength of the purchase price. It's a little thick, but melts nicely (I used Black & Decker CI500S Dual-Temperature Soldering and Craft Iron) and I'm impressed with how quickly and cleanly it melts. I've used this to successfully solder in new batteries for my Gameboy games, and I couldn't be happier.

It was fresh solder, and the flux was more than adequate for 12vdc wiring that I needed to do.
Seems to be really good stuff. I'm no electrician, but know the importance of having quality tools (especially when you lack the talent/technique/knowledge to work around the faults of poor quality). This is definitely easier to use than the typical thick stuff you would find packaged with a new soldering iron, or get in those small tubes. My local electronics supply warehouse agreed that it was a quality product, I trust their knowledge a lot more than mine.
It comes in a sturdy case (unlike the spring style tubes which i hate) and is nice and easy to use.
I definitely give it an A+ for everything I've done with it.

If you are soldering wiring get this instead of the lead-free. This melts quicker and flows much better. End your frustration!Published 1 day ago by zinger
The item works as expected. I am an amateur at this and bought this to add some connectors to a universal wiring harness for my Jeep.Published 2 days ago by Jonathan
