You guys who are interested in the possible repair of a failed cloud may be interested in this post of mine from last August
<LINK>. What I didn't mention in that post (I was being cautious of violating the warranty) was that I was successful in soldering the power lead back on the ceramic heating element. However when I tested the repair by energizing the unit before reassembling it the solder liquified in less than 5 minutes and the repair failed. Rosin core solder used in electronics melts at approx. 370 deg. F, so the ceramic heater easily reached this temp in short order even without being encased in it's insulated enclosure. Silver solder may be the ticket with a melting point of approx. 840 deg. F, but the problem is that it takes a torch to reach these temps and unless the ceramic heater can be slowly pre-heated to these high temperatures the application of a torch is going to crack the ceramic ruining the heater.
Using the high temp silver infused epoxy adhesive previously linked to *may* work... I wish you luck with that!
