Отзыв о Водонепроницаемые разъемы Sopoby'S для пайки - полный комплект из 140 шт. для морской, автомобильной и домашней проводки от James Cypert

As an Engineer I found this to be a great idea so I tested it out on a piece of wire which I stripped and twisted together. I slid one of the red shrink sleeves over the joint then used a lighter, and after a few seconds of moving the flame back and forth, the solder seemed to melt and it looked to be a good connection. Then I tried pulling it apart and the connection failed.I then tried again, but this time I dipped the stripped ends of the wire in Flux which is a very necessary part of the soldering process. Not only did the joint work perfectly after using the flux, it also heated up much faster, reducing the chance of melting the plastic. Without the flux you can get what is called a "cold" joint where the solder melts but doesn't really flow onto the wire.I don't know if the average person has flux laying around but it would be great if they included a small tube in the kit. Or better yet, figure out a way to line the inner part of the shrink tube on either side of the solder, so it gets applied to the wire when things heat up.Great idea and works in a pinch when you don't have electricity for a soldering iron - just needs flux!
