![]() ![]() It's not that it can't be done, but the variability involved would invite disasters. "Cold" solder joints are a problem even with low current electronics wiring, and high current wires that also need mechanical strength invite more problems. Soldered connections invite a lot of poor quality work, and no chance of standardization for larger connectors. However, as long as NEC acceptable compression connections are used, at least there is some standardization involved. Even just moving a solid wire around a box can loosen a screw connection. A compression connection will many times become a bit loose after a period of time, especially if the cable is a stranded variety that may compress more over time. I suspect that soldering a joint does make an electrically better connection, and one that will be a low resistance connection for decades to come. Obviously this isn't to code, but it works VERY WELL. That way you don't see the tape, and it looks really good. I wrap the junction with some electrical tape to protect the heat shrink tube, and slide the tube over it all. Sometimes I touch it up with some solder around the end of the tube if the solder doesn't come out around the whole wire. When I see the solder ooze out the ends of the tube around the wire, it's done. I heat up the tube with the torch, and feed solder in through the hole in the middle. I have an itty bitty butane torch I use for soldering, it's blue and says "pencil torch" on the side. ![]() Then I loosely crimp the tube around the wire with the hole pointed up. I make the tube just a bit longer than the stripped wire, just enough for the solder to get in there. Then I drill a hole in the tube for the solder to go in right in the middle. Slide a piece of shrink tube up the wire a ways so it doesn't get shrun accidentally. I take a short piece of copper tubing that's close to the proper diameter, and cut a slit down the side. For your convenience, they are pre-filled with an oxide inhibitor compound.If I'm gonna splice fat wire using solder, I use copper tube. Replace traditional split bolt splicing with these preinsulated connectors that quickly and easily connect wires and cables for a fraction of the time, effort, and cost.Īirmont Products Black Splice Connectors are insulated with heavy-duty high-dielectric rubber and a thick vinyl coating to ensure optimum performance and long-term usage.
