This is an old station (i have no idea about its original release date), it's got a 16C pic in it with plain eprom memory. I wanted to get a newer model oiginally (a 2ch one with the suction pump and hot air pencil), but they offered me this 3ch, but previous model for the same price. Considering that Weller is not really going into the right direction, i was happy with this older one, but it looks like you cannot really trust these either. :-( I also got a single channel WD1 too which i bought earlier than this. It is working OK (yet).
