Hi all. I have been having some troubles soldering some type of cable, and i wanted to know what do you have to say about it.... anything you know about it. This cable seems like a silver cable (at least have that color, i don't know if it is). The last time i saw this type of cable was in a UPS unit (this things used with the computer for power failure). The problem i have is to solder it. I leave the 40W solder a lot of time, and still is dificult to get it soldered. Please, post whatever you know about it.
