Soldering is a process in which two or more metal items are joined together by melting and then flowing a filler metal into the joint—the filler metal having a relatively low melting point.
The metal to be soldered is heated with a soldering iron and then solder is melted into the connection. Solder is a metallic "glue" that holds the parts together and forms a connection that allows electrical current to flow. You can use a solderless breadboard to make test circuits, but if you want your circuit to last for more than a few days, you will want to solder the components together. Higher wattage soldering irons are not necessarily hotter; they are just able to heat larger components. Solder that is used to join copper pipes has an acid core, which is appropriate for pipes, but will corrode electronic connections.
To use the braid, place it over the solder to be removed and heat it from above with the iron. The smoke that will form as you melt solder is mostly from the flux and can be quite irritating. Reliable operation of a circuit with soldered connections depends on good soldering practices. It is helpful to attach each part to a piece of paper and write what it is and its value (for example, resistor #1: 100 ohms). Some components, such as LED's, must be placed the correct way around in order to function. Leave IC's in their antistatic packaging until you need them, then ground your hands by touching a metal water pipe or window frame before touching the IC's. You do not need to tin the tip before every joint, but you should re-tin it if it has gone dull when the soldering iron has not been used for a few minutes.
To solder, heat the connection with the tip of the soldering iron for a few seconds, then apply the solder.
Remove the tip from the connection as soon as the solder has flowed where you want it to be. Don't overheat the connection, as this might damage the electrical component you are soldering.
If you are soldering a wire (called the lead) onto a PC board (on the track), it should have a volcano shape.
Clean the tip of the iron on a damp synthetic sponge as soon as it starts to change from a silver color.
Using too much solder can cause a solder bridge, which means that two adjacent joints are accidentally connected. Using too little solder might result in poor electrical continuity between the board and component.

The solder melts when it is heated by the soldering iron, but the metals being joined will not melt.
It prevents oxidation of the metals that are being connected, and enhances the ability of the solder to "wet" the surfaces that are being joined. Thicker solder might make soldering small joints difficult and also increases the chances of creating solder bridges between copper pads that are not meant to be connected.
If a power cord is touched by a hot iron, there is a serious risk of burns and electric shock.
Make sure all the pins are lined up with the socket, then push down firmly with your thumb.
The tip of the soldering iron heats both the copper pad and the lead from the electronic component.

By absorbing heat, the crocodile clip will reduce the heat that flows to the component, helping to prevent damage. The solder in a good join will be shaped like a cone, with solid contact between the solder and all surfaces to be joined.

In addition, it also has a heat resistant plastic handle that is light weight, and is quite super convinient. Once your order is shipped, you will be emailed the tracking information for your order’s shipment. The solder in this picture is coiled inside a plastic tube; it is pulled through the top as needed.

Solder braid is used to remove solder; solder is "soaked up" into the braid when it is heated by the soldering iron.
The wire strippers can be adjusted to strip the plastic covering off of various thicknesses of wire.
