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.
