Silver soldering BS blades or Carbide?

[stevec]

Rick, I had one that was a bit "Mickey Mouse" it used a car battery as a power supply and had a little jig to align the blades but it didn't work well and someone told me the bimetal wouldn't work because of the dissimilar metals involved. I suspect it was the inferior design and cheapness of the device.
I think "Bandit" is very apt in the name of this P.O.C.
