Soldering Iron Cheap
Now that the tops are tabbed, flip them over (sunny side down), but, slip out the tabbing strip from the first one so it lays within the back of this next. Do the same all of the way down your "string". You`ll be soldering the strip to your contact points on the back of the cells. If your cells are like mine, there will be 6 small whitish contact squares. Make sure that your tab strips line up so they really shall sit throughout the contact spots then apply flux to the spots. Hold your soldering iron to your strip at that moment when its hot, touch the solder wire to your true point and allow solder flow, don`t apply a lot of and do not over temperature the contact since you may damage the mobile. An alternative solution is to utilize a solder paste in the contact, lay the tab on and hold the iron on the point for me, this was a better solution till it flows. Perform some same for many six contact points, now have two cells linked. Continue this process for the cells that are solar the sequence.
This is a pretty idea that is good make sure that you`ve got good solder connections, by exposing the cells to light and testing the production voltage. At the least, check each string, it`s far too late when you yourself have connected them all up to locate you`ve got a solder that is"dry somewhere while having to trace it back. All soldered together, there is one more thing to do with the string of cells. The last one, with its "top tabs" free at this stage you will have at one end of the string. But at the start of the sequence, absolutely nothing to connect with. And that means you have to solder a quick amount of tabbing strip to the straight back associated with "top" (first) cellular to possess one thing to connect to and complete a circuit. Therefore, regarding the "first" cell, solder tabbing strips across the trunk connections with an adequate amount of a free end to allow you one thing in order to connect to. Now you certainly will have connecting tabs at both ends of your string ready to connect with its neighboring string or perhaps 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.

With copper it is necessary not to miss a step or there may be disastrous results. Keep in mind these steps and you`ll be on your way to a solder that is perfect each and every time.
Here you will find the 5 steps you`ll want to try get a Perfect Solder Joint every time.
Slice the pipe to size
Clean & debur the pipe
Clean the inside associated with the suitable
flux the outside associated with the pipe therefore the inside of the fitting
Time 2 solder
Slice the pipe to size: gauge the duration of pipeline you shall have to join your piping system together. Using a tubing cutter, cut your pipe to size (twice remember to measure and cut once).
Clean the pipe: With some sand fabric or paper, sand each end of this pipeline until shiny. Make certain the manufactures natural oils are from the pipe. Rub having a cloth to eliminate any sand or copper residue.
The deburring device regarding the end associated with the tubing cutter, helps in getting rid of the rough sides that could cause leaks in the future. Using your pipe reamer in the tubing cutter, ream the within sides associated with copper tubing removing any burr`s. You`ll need a edge that is smooth.
Clean your fixtures employing a tubing brush properly sized for your pipe. To speed the process along we slice the cleaning brush near the top of the handle and insert inside of my drill.
Turn your drill speed on high and clean the within hub of the fitting. Until it has been removed if you see any dark spots inside of the fitting keep cleaning the area.
