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?


All the thermal fuses I've seen were crimped on.

TDD
I have successfully soldered quite a few. Don't try it with a small
or low wattage iron though. I use a 250 watt weller gun - barely need
to touch it to get the solder melted - use aligator clips to hold it
in place and act as a heat sink.
