    It's also important to line up the split of the metal crimp with the dies crimping protrusion, if they are split.

    The reason the numbers increase as the wire diameter decreases is wire is measured as how many can fit into a square inch. Known as the Stubs Steel Wire Gauge. They use similar for IV cannula sizing.

    Oh cool! :D I bought a crimping tool just like yours by misstake today, when I actually wanted a cable-stripping tool (yeah, I must be And being a complete beginner in this area, I had absolutely no idea what I had brought home! I'm not an native english speaker, so the word "crimping" to me sounded like something you might do when peeling a cable. Also the store employee actually told me it was a cable-stripper, and I was in a hurry to catch my bus. Anyways, now I realize that this is exactly the kind of tool I'm going to need after stripping the wire! =) Funny how misstakes can end up being lucky sometimes!

    Overall, very good instructional video on the basics. Using the correct tooling is absolutely critical. Love how you stress that. Note: You should NEVER crimp a soldered (tinned) wire! There are several failures that can result from doing that. It is a DEFECT in all military, aviation and medical application.

    Id get into crimping however i see millions of connectors and not sure how to get started. I do know how to solder good though so i just solder and use a nice good quality shrink. Glue lined shrink is best as its marine grade and blocks moisture out. Where does 1 learn ratchet crimping? So many connectors id buy wrong crimper lool.

    Nice video!! Can't stand videos that are out of focus or can't hear the narrative. Anyway, wondering if these
    connectors are out there somewhere and what they might be called? I need to reconnect the wiring to a glow plug in my car. the original plug was already beat so I added a few layers of heat shrink to beef it up.

    You are a demigod amongst mechanics and provide inspiration to us lesser beings.
    When removing insulation with SCISSORS-type strippers, close the tool around the wire then open it back up without pulling off the insulation. Rotate the tool (or wire) 90 degrees, then clamp down again. Done right (with quality wire) and you can pull the insulation off the wire with your thumbnail.
    To chime in regarding solder, I've been known to use it if the wire won't otherwise hold a crimp. One might rightly ask, "Why not just solder the connector in place and skip the crimp?" With insulated connectors I skip the crimp if I can pull the insulator off and slide it back up over the wire insulation. I then solder the connector on then pull the insulator back over the bare metal. Most of the time the wire insulation is too thick, though.
    Great job Eric. Thanks for all of your advice and humor.

    Agreed proper tool is very important. I have the same problem. The crimp tool I was using is awful. I don't solder before. I will solder after in some cases, like on my old tractor where the connects will be exposed to moisture, high humidity, higher stresses (vibrations, etc), but that is mostly to keep out corrosion and added security. I would expect it to be a problem soldering before crimping as the solder would make the wires harder and less willing to form but that would also have been using a cheap awful crimping tool. Knowing how to properly crimp is also important. I made crimps incorrectly for a while because someone showed me how to crimp and they were also doing it wrong.

    Good video, really great advice and tutorial thanks.
    Soldering or rather tinning the wire ends certainly makes for a longer lasting, stronger, lower resistant (low impedance) joint, that is less susceptible to black wire. so better for damp environments.

    Sorry if this is a dumb question, but does the gauge of the wire correspond to the entire cable, including the insulation, or just the inner wire?

    Because you cant see the middle section where the conductor meets, is it alright if you accidentally crimp the part where the cable's own insulation is?

    Thank you so much for making this! I hadn't thought of the heat gun before but will start using that from now on. I'm about to take on a project of installing an aftermarket Android stereo so this tutorial is perfect. I also enjoyed what you said about the crimping being very relaxing. That, of course, is if you're not using the cheap-o Harbor Freight stripper's crimpers that are 1/16" thick and act like scissors when crimping.

    Never ever tin before you crimp. Soldering after crimping is ok, though.

    I solder any connections that don't demand removal and sometimes even those. Always a better connection especially in cases where exposed to environment. Shrink tube And/or electrical tape over connection. For extreme weather exposure we use tar tape.

    hay its good your passing on good information and I used to work as a quality assurance manager and your crimpers that click they should not over crimp on the job we had a lot of them and we got the best over a $100 and they are mad almost full proof and their is a bimba cylinder fixture for those tools with a foot pedal control they are nice, and your right, the right tools make the difference and wire striping in the industrial market and military grade you cant even have one strand missing because the crimp wont be as strong its a proper mechanical crimp, and solder is only a electrical connection not used as a weld not strong enough and their is a term about how clean everything is, they say is it sanitary. but I'm glade someone is not putting bullshit out their for once, hey good luck and if your installing amps and doing repairs if your interested I could tell you how it enhance amps I mean louder clear not distorting everyone I have done for people say its the best amp they ever owned and wont give it up big difference
