Hello, You can add small pieces of wires to each wire with the same gauge and type and color. I suggest you solder each connection if you are worried about resistance getting bigger or a probability of a loose connection. Then make sure you taped all soldered connection to eliminate shorting with each other.
Thanks for your response, I was planning just to twist each wire and protectthem with the shrink tubing
Hello, Then you could have a probability of corrosion problem in the future. If you do have a soldering iron, I suggest you solder the connection to make the connection much better, then use the shrink tubes for added protection and insulation.
the wires will be in the attic and covered with the shrink tubing, I will joint with the same copper material so I don't think possibility of any galvanic corrosion due to disimilar materials and also protect with the tubing, will protect from external factor, don't you think?
Depending on your location, if you are near salty air, I have seen corrosion on wire connection that were not soldered. If you are far from oceans or sea, then I can say it could be safe to just twist the splice connection. Well, its up to you, mine is just a suggestion.
Thanks and I really appreciate your feedback is good to have another opinion, in case going with soldering can I buy a simple welding kit at Lowe's or Home Depot or have to be something more specific?
Can I weld with tin?
Not a welding kit. Just a small 100 watts soldering pencil would do the job. Just do not forget the soldering lead, if they sell by the yard, two yards is more than enough to solder 6 leads. And yes, it could be available at home depot. Nothing fancy.
Welding would make the job more complicated.
ok understood, thank you very much for your help, have a great day
You too. Thank you for using this service and you are very much welcome.
