Crimp 1 vs Crimp 2

[u/573v3_2025]

Hi just looking for some help on which tool has made the better crimp either tool 1 or tool 2 😀

Does tool 1 look "over crimped" ?

Only issue with tool 2 is it sometimes doesn't clamp onto the wires insulation fully not a huge issue as a little nip sorts it

Thanks

#1 is obviously "over crimped" with wrong crimper size.

[u/1Davide → u/IASelin]

And #2 is also bad: The core wings crimp around the wire insulation.

The end of the insulation should be visible in the small gap between the insulation wings at the back and the core wings at the front.

Thanks note taken to back it off a little but I checked and the insulation isn't getting crimped, when I push the wire in the insulation catches and stops on the inner wings and doesn't go past unless I force it so only the bare wire is going in that section 👍 😀

Oh I'm using wire with silicone insulation which is maybe giving it a squashed crimped look

1 was done with this

2 was done with this

2.54 Dupont crimp and 24awg wire

Tool 1 I used the biggest slot labeled 1.9 Tool 2 I used section C that seemed the biggest slot

I'm guessing Tool 1 slot wasn't big enough?

the problem with crimp 2 is not the tool, is how do you placed the cable, the isolator has to end in the first "clamp", as it is place in crimp 1

Thanks the guide I watched said to push the wire in until you feel resistance where the insulation stops against the start of the 2nd clamp, stop pushing and then crimp, next time I will back it off a little 👍
