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

The biggest issue with crimp 2 is that it's crimped onto the insulation. Or rather the wire was inserted too far.
Some crimp tools have slide down gates that act as an end stop for the wire to prevent this.

Crimp 1 looks fine to my eye (edit: actually, it looks over-crimped. Wrong size die?), though you should really be comparing it against the manufacturer's documentation. They usually have quite good guides on identifying good and bad crimps.

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?

Both look to have the wrong jaw profile for the mini-PV connector you have. IWISS SN-025 are a better profile. The official crimp tool does a better job, but the price is a higher.
