Uninsulated crimp tool

: OTOH, I avoid the pre-insulated crimps. You can't achieve a gas-tight : crimp with them.

In particular I don't like them at all on older wire which has often oxidised under the insulation ... the aluminium crimps are supposed to form an intermetallic bond (cold / pressure weld) between the crimp and the wire and with lots of copper oxide around that just doesn't happen as well.

I do solder crimps occasionally, but it's more as a belts-and-braces way of keeping moisture out of the joint.

They also look decidedly naff on a car. Alarm installers use them - need I say more...

All the ones I buy.

Just my twopennyworth, but is not a crimp?..a "CRIMP"...and by its definition, NOT a solder connector?. Having also spent years in the wiring industry, why do some people insist on trying to change the purpose of some connectors. Just buy the right ones, and the right tool !!!!!!!... ( If you havent got it, then borrow it). If soldering a crimp was a good idea, it wouldnt be sold as a crimp. I agree that sometimes, peoples ideas seem alright on the surface, but how many people have had failed connections a few years down the line, that have been "bodged" by cowboys, that had said at the time "see, that solder job has worked a treat...no problem".................

Ian,

I think you will find what your after on

Good luck!

Not that good unfortunately, it can leave the joint brittle and more liable to fracture. Its best NOT to solder crimp terminals.

Greenweld Tools do a crimper for around £15 (Ref: ST710278). I bought one a while ago and I have been very pleased with it. I have no other connection with Greenweld except as a satisfied customer etc.
