Hi all

I have recently been repairing a crepe cooker and a hotplate where the thermal fuse has gone. My problem is how best to make the joints between the stranded wire and the solid strand legs of the replacement thermal fuse. The original thermal fuse was connected via a kind of crimp. However, it is much neater and stronger than I can make with a standard crimp tool.

On the hot plate there is very little space to make the joint.

Is there a special tool for this work or an I missing a technique or something else?

Thanks in advance
 

Yes, there is a special tool, there's a 'special tool' for all connectors. But you don't need it. If you can just make a secure crimp, don't worry about how pretty it is. Think about it, all you are doing is squashing a ring of metal.
 

Thanks for the reply. I have a standard tool for the crimps. My problem is making the joint small enough and strong enough. If I pull the thermal fuse reasonably hard its leg slides out of the joint.

This is the type of tool I'm using, with the smaller crimps

I notice it got a poor review so maybe I need a better quality tool.
 

Almost every crimped wire connection I have seen has the wire loose in the crimp and it easily pulls out.
I have always soldered every crimped copper wire connection to guarantee a good connection.

Maybe you are seeing a crimped connection to a nichrome or aluminum wire that cannot be soldered.
 


I don't think you want to solder a joint that's going to get mighty hot; that's why they use a crimped connection to begin with.
 

It is correct to say that solder can not be used as the appliance gets hot.

Maybe I'm expecting too much strength from the joint.

How much "strength" are you expecting? This is the normal way heating appliances are assembled. As said, you can't use solder, so you don't have many other choices.
