Knowledge Base - How To:- Soldering
I just thought I'd do a quick guide for anyone that needs it. It's a guide for those who aren't too confident when it comes to soldering to at least allow them to have a go at repairing things themselves. After all, if you're repairing an electrical system and are having problems with parts not working correctly, at least you'll know it won't be any of your joints, thus eliminating a variable in the fault finding equation.
Early apologies if these pics are a bit dark, I had to take on my phone and only have two hands!!
Ok, to begin with the tools you will need;
From top left we have wire strippers, top right are snips (side cutters), bottom left soldering iron and bottom right is the solder.
We're going to join these two wires together (below), I've used mains cable for the example as it's nice and big for the camera to see and the colours are distinctive enough to tell what's going on. The principles work the same on other types and gauges of wire though.
Using the snips cut the ends of the wires back so they are nice clean cuts (as below)
Using the wire strippers, strip about 1/4" to 3/8" of the insulation back off the wires, (doesn't have to be that accurate)
Place the bare wire between finger and thumb and twist so all the separate wires are bound together
Pick up the separate cables and with the two ends opposing each other place one bare end behind the other, twist the tips in opposing directions until both cables are neatly wound together
Next we need to plug in, turn on and allow the soldering iron to warm up. While this is happening, take the yellow sponge from the iron holder and rinse it under a tap, give it a squeeze out, you want it damp, not dripping wet.
(If it is safe to do so beforehand then the soldering iron could be heating up while you prep the wires.)
In this instance the soldering iron i am using wasn't left clean by the previous user, as you can see by the picture below
