How to Solder Flexwatt

Been asked by many, and seen many asking how its done. As most know clips are a PITA and are the main cause for electrical fires/malfunctions when they get loose.

This is just a Quick Video on how to solder, if followed you will be successful on this every time.

Only thing I see is there is no flux when you actually connect the two joint together. I was always taught there needs to be flux everytime you heat it, as it leaves an opportunity for oxidation when you reheat them, which can cause a cold joint. Reason their not good is someone who is inexperienced may not identify the cold joint and it feels snug at first, but vibration or temperature changes can break them. Since you did this as a how-to for the inexperienced, you might want to tell them to dab some flux on the joint before they connect the two together. little tin of it cost a dollar.

good idea to do this though, someone needed to.

Flux isnt needed when soldering this application. Now when doing other applications like circuit boards and other stuff where you dont want the oxidation to happen and ruin the circuit then id suggest using flux.

The only thing that I do different is that I prefer using the liquid electrical tape on the soldered end. Thanks for the informative video......:gj:

I want to use it, But i cant find it anywhere under $5 to make it worth not using the tape.

I still see an advantage to knowing there is no oxidation in the joint, especially for the inexperienced. I've solder quite a few automotive wires together with the same method and found some of the joints broke apart, given a car is going to go through a lot different conditions than a rack. Later I learned to dap the wires in the flux before hand and it was never a problem. Things my failures have taught me.

The main reason that I use it vs. the regular tape is because I was give a bottle of it....lol

Ive never used it for Flexwatt, but no harm in doing so. But when I did electrical wiring up peoples car audio systems, Volt modding GFX cards I used Flux.

Flux is sometimes in solder now, or mine is anyway.

yes it's in the one he using, rosin core. But it burns of when he tins the wire and the flex, so when he actually connects the two, there's none left.
