Some time back, I managed to scrounge up another Thermalyne heat
treating oven. Cute lil thing, about a 5x5x8 cavity.

Checking to see why it wouldnt heat, I found that one leg of the
heating element had broken.

This particular oven has three sides made of the element embedded in a
ceramic, so three sides come out at one time. The leg from the switch
broke off flush with the top of the ceramic. I carefuly chipped away
at the ceramic until I got about 3/8" of the lead exposed. It needs
about a 3" piece of some thing spliced to it, to make the run to the
terminal strip. The original was just a long piece of the heating
element. Ive tried crimping a wire connector to it, but it seems to
not grab very well and pulled loose while reinstalling the unit. I
gave it a quick shot with the mig welder using regular welding wire
and gas, and it held for a bit, but was still a bit fragile and broke
free while installing it.

Ive since installed the heating unit, and have a new lead run and
overlapping the stub.

How do I splice them together? I do have temporary use of a mig with
gas, and stainless wire as well as regular. I also have a tiny bit of
silver solder, regular brazing rod, etc etc.

Any suggestions? Its possible I can excavate a bit more wire for a nut
and bold mechanical connection...but would rather not break out any
more of the ceramic.

Thanks in advance.

Considering the application, I'd go with a mechanical connection.
