This guide will show you how to properly tin wires for soldering to speakers, circuit boards, motors tabs, or any other solid surface. If you are splicing wires (soldering two wires together) a slightly different technique is required.


Step 1: Strip back ~1/32" of insulation from the end of the wire.
Be sure to use the 32 AWG hole on your wire stripper so you don't cut through the copper strands.


Step 2: Hang 1/2" of wire from the stripped end off the end of the workbench.
Get your soldering iron heating up (approximately 625F degrees seems to work well).
Make sure the tip of your soldering iron is shiny (stick the heated tip into a tin of tip tinner [here we will put a link to the TCS Tool Tips] if it isn't shiny).


Step 3: Touch the solder to the tip of the iron to create a very small blob on the end.


Step 4: Use your pinky finger to hold the wire on the table while bringing the solder and soldering iron together on the stripped end of the wire. All 3 items should make contact at once and shouldn't need to be in contact for more than 1 second. If you don't get good coverage on the first pass remove the iron and let the wire and solder cool before bringing the iron back. If you overheat the insulation it will pull back from the copper and leave you with exposed wire risking a short.


If everything goes well, you should be left with perfectly tinned wires with just a bit more than 1/32" of exposed, tinned copper. Your wires are now ready to solder to something.
