Soldering irons are the base for construction improvisation

is a hand tool used in soldering. It supplies heat to melt the solder so that it can flow into the joint between two work pieces. A soldering iron is composed of a heated metal tip and an insulated handle. Heating is often achieved electrically, by passing an electric current through a resistive heating element. Portable irons can be heated by combustion of gas stored in a small tank, often using a catalytic heater rather than a flame. Simple irons less commonly used than in the past were simply a large copper bit on a handle, heated in a flame.
Soldering station
are most often used for installation, repairs, and limited production work in electronics assembly. High-volume production lines use other soldering methods large irons may be used for soldering joints in sheet metal objects. Less common uses include burning design and plastic welding.
Solder is a thin tube, usually rolled in spools, made of various metal alloys. Its job is to hold the individual components together. The individual components and their quantities can vary, but for computer electronics, you re usually looking at a 60% tin and 40% lead. Lead-free solder is also available, though it has higher melting temperatures and less wet ability, meaning you may need a better soldering iron to use it and removing it can be more tedious. Lead-free solder is better for the environment and has other benefits, and they function more or less the same way. Many who ve never used a soldering iron are afraid of damaging equipment, but more important is the danger to you!
Soldering irons
get really hot (think, and solder itself is molten metal. Be sure to wear safety glasses, keep loose clothing and hair out of the way, and be careful with your fingers. Better still, use protective gloves. Solder can contain lead, so be sure to wash your hands thoroughly after handling it. It s also really important to work In order to conduct heat properly; your soldering iron needs to be free of any old solder. After being exposed to air, it oxidizes and thus insulates against heat. We want heat to conduct so that we can apply everything quickly and efficiently. A dirty tip means that you ll have to hold the iron on longer and risk heat damage to the PCB, and nobody wants that. Keep a wet sponge handy, and after the soldering iron is fully heated, softly scrape it against the sponge to remove old solder. The tip should be nice and shiny, or at least very close to it. In a well-ventilated area the fumes from the rosin can cause damage to your lungs when inhaled. Honestly, it s more common sense and preparation than anything.
When removing a connection or undoing a mistake, you can often resolver over the original and add a touch of new solder. If you want to take the extra step and do it right, you can remove the old solder
completely and start with a fresh work area. There are two tools you can use for this, a vacuum-based solder sucker, or a solder wick.
