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. Move the iron away carefully and let the solder cool. It takes a few seconds for the melted solder to cool. During this time, the alloy is slushy, and movement before it cools will result in a weak, rough-looking "cold solder joint" which is unreliable and must be re-melted. Do not try to melt a blob of solder onto the iron's tip and carry it to the joint. The flux will be gone and the solder won't flow properly.
7. The slushy phase is very short for 60/40 solder, but can last for many seconds for 50/50. Plumbers used to take advantage of this to make "wipe joints" by wiping and forming the slushy solder with a rag as it cools. That is very seldom done these days--and NEVER in electronics. 63/37 solder goes from a liquid to a solid almost instantly, making cold joints rare. Buy it if you can; you use very little per joint in electronic work. I bought a 1-lb spool of it many years ago and still have most of it. I misplaced it recently, which is why I am here on Amazon.
8. Flux: Most metals quickly react with air to form an oxide film, starting as soon as they are cleaned. Aluminum is a very active metal, which would be unusable outdoors if its oxide film were not protecting it from corrosion. It makes soldering it very difficult, so it's usually crimped or welded.. Copper and brass oxide films will also prevent solder from adhering, so even if you CLEAN before soldering, you need a flux to dissolve and prevent oxidation at the joint during soldering. Acid flux is used in plumbing as it is very effective, but it is corrosive and must be removed after the joint is made. Rosin-based flux is less corrosive and can be left in place. It is usually supplied within the center core of electronic solder such as this, so you don't need to buy a can of it unless you are plumbing.
The secret of soldering: Lots of heat, for a very short time. Trying to protect parts from heat by using a low-temperature or undersized iron will actually result in MORE overheating of the parts because the heat will have more time to travel to the part even if the solder joint is unsuccessful. Do this: Use a good temperature-controlled soldering iron such as a Weller W60P 60Watts/120V Controlled Output Soldering Iron with a 1/16" or 1/8" tip for electronics or up to a 1/4" tip for heavier work. I use 600F temperature tips for 60/40 solder, though 700F might be better for lead-free solder. Keep the tip clean by melting a bit of solder on it and wiping it off quickly with a damp paper towel or sponge to get a smooth silvery surface. Modern irons come with iron-plated tips for long life. NEVER try to file them like you grandfather did!
If you are a newbie, you ought to get a training kit to start. I have been buying Elenco AmeriKit Learn to Solder Kits for my kids, nieces, nephews, and friends who want to learn to solder. These come with decent tools (though the soldering iron is not going to last 40 years like my W-60.) There is an excellent instruction sheet for soldering and desoldering, with a simple circuit board and parts to work with and hopefully build a working gadget. All at a remarkably low price.
Disclaimers: I have no connection with the products I mention. My 5-star rating of this item is based on Alpha products I have used in the past. I have not yet ordered this. As a long-time amateur radio licensee, it is part of our culture to help others. I hope you find this useful and perhaps join us.
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 is a bit thick for smaller electronics projects so I purchased some 0.3mm solder wire to supplement this when I need very little solder for a small electrical connection or component.
Moreover, as it contains flux, the solder helps minimize the oxides that tend to form when you have hot metals in contact with the air.
Only thing I’d like differently is for the thickness to be twice the size, but that’s not their fault I just couldn’t find that size for my application. For the application I was using it for, it still worked great but had to unroll a few feet a couple times to have enough to solder the 2/0 cable ends & cable together. For fine electrical applications such as 16 gauge wire, it would be the perfect size.
3/1/19 update: working perfectly for me Electrical application! I covered the soldered joints with some electrical shrink wrap to keep it from corroding.

El acabado que deja.
Cantidad suficiente de flux interno.
No tiene olor desagradable (aunque utilices extractor de humo el olor se alcanza a percibir, como cualquier soldadura)
No me gusta:
El grosor 0.062", aún así no dudaría en recomendarla al 100%.
