Can you solder a thrmal fuse in place?

Someone gave me a disassembled sandwhich maker (heater). The
plastic/Bakelite? is broken where one of the four screws goes, but can
probably be fixed fine with PC-70.

The thermal fuse is burned out.

I have about 6 new thermal fuses of different sizes.

Can I solder the fuse in or must I crimp it?

In the past I've figured soldering would melt the fuse, but I haven't
had such good luck with crimping, probably because I don't have the
right sleeve or maybe not the right tool. With wire cutters, there's
a tendency to cut right through the whole thing, and with anything
duller, it's hard to squeeze hard enough.

Also, in the past the temp has burned off the melted fuse. What temp
would use for this small device, which I think just warms two slices
of bread. Would the amperage be a clue at all? The melting temp
of bread?

I can't spec the temp of the fuse for your device, but yes, I always
solder in my thermal fuses; just did one the other day per another
thread. Of course, I've been soldering for a living for 25 years, so I
do the soldering in about 1 sec. If you fumble around with it you'll
cook the fuse.

BTW, using a low temp soldering iron, heat sinks, or other means to try
to keep from cooking the fuse are counterproductive.
