Notice to All:
By now, many of you have seen Dave's latest soldering station related video: EEVBlog #1160 - Weller Responds! concerning the safety of the Weller 1010.
I just wanted you to know that the fuse in the back of the ADS200 is in the primary side of the transformer for safety. On all of our products, we have always had a fuse (or circuit breaker) as the first items on the Mains. Since the Weller 1010 is more of a budget station, I suspect they probably omitted the fuse as a cost-cutting measure. If you look at the ADS200 back panel image attached, you'll note PACE even supplies an extra fuse (not that you'll ever need to use it)!
