Hi guys, my husband the microwave engineer was admiring my new proportional thermostats. And he asked if they output DC or AC? I... don't... know? Does anybody know?

Also, someone somewhere suggested attaching the wiress to the flexwatt with solder rather than the crimping tool, because the crimp points tend to build up heat over time and can be fire risks. If anyone has strong opinions about that one way or the other, please feel free to share.

But has anybody actually soldered the wires to the flexwatt? Did you just solder them to the same basic place you crimp, or what? Pictures would be extra awesome.
