The Gun
The soldering gun is supposed for applications which could require more temperature than the iron. The output that is robust of weapon ranges from 100-240 watts, allowing it to reach degrees as much as 2400 F, so that it can be used in jobs that require melting weightier solder or even a cutting right through stronger steel. For instance: Plumbing utilizes the weapon to seal copper piping, stained glass artisans make use of it to fill the room involving the glass shapes, and steel worker will even make use of it to cut precise forms out of sheet metal.
Both essentially serve the same function,heating and melting metals, based on their power they must be used for completely different purposes although these tools. This just shows the way the application of soldering is indeed broad; it is not limited by one application, and also calls for strength that is different. Therefore, whenever attempting to understand the difference between a soldering gun or iron, its more crucial to understand what has to be accomplished aided by the device. The soldering iron won`t have the capacity to melt strong metals or solder therefore the soldering gun is entirely impractical for precise electronic soldering or jewelry that is crafting.
This is just a little introduction to soldering solar cells together. You may already know, but that there are both "tabbed" and "un-tabbed" solar cells on the market before we begin, it is good to remind you. Tabbed cells are a a bit more expensive, but if you should be intend to build more that certain panel, they will save a heap of the time, broken cells and frustration. Solar panels are delicate, therefore the more you handle or mis-handle them, the higher would be the chances of breaking them. Soldering cells that are solar care, and because untabbed cells effortlessly requires not only soldering right across a cellular, there clearly was twice the task and - well, odds are you may break some.

Now that the tops are tabbed, flip all of them over (sunny part down), but, slip out of the tabbing strip from the first one therefore it lays on the straight back regarding the next. Do the same all the real way down your "string". You will end up soldering the strip towards the contact points on the relative straight back of this cells. If the cells are like mine, you will see 6 small whitish contact squares. Make fully sure your tab strips line up so they will sit throughout the contact spots then apply flux to your spots. Hold your soldering iron to your strip on the spot so when its hot, touch the solder wire to your true point and allow solder flow, don`t apply too much and don`t over heat the contact since you may harm the cell. An alternate is by using a solder paste on the contact, lay the tab on and support the iron on the point for me, this was a better solution till it flows. Perform some same for all six contact points, are in possession of two cells connected. Continue this procedure for all the cells that are solar the string.
This is a pretty good clear idea to make sure that you`ve got good solder connections, by exposing the cells to light and testing the output voltage. At the minimum, check each string, it`s far too late when you yourself have connected them all up to locate there is a "dry solder" someplace while having to locate it right back. All soldered together, there is one more thing to do with the string of cells. At this time you will have at one end regarding the string, the past one, along with its "top tabs" free. But at the beginning of the sequence, absolutely nothing to connect with. So you have to solder a quick length of tabbing strip to the back regarding the "top" (first) mobile to possess one thing for connecting to and complete a circuit. So, in the "first" cell, solder tabbing strips across the trunk connections with an adequate amount of a free end to permit you something in order to connect to. Now you will have connecting tabs at both ends of one`s string prepared to connect with its neighboring sequence or even a connector bus. Really, now it saves some double handling that you have read this far, its a good idea to do solder this "first" set of back tabs before soldering up a string.
