Thanks for your reply, I just wonder if the grounding the only difference in these soldering irons. they vary so much in price and part complexity its just unbelievable.
HI perhaps a bit off topic, but I would like to use the opportunity to ask someone that obviously knows the ins and outs of soldering irons .I have been soldering for years now as part of my RC Hobby, but never owned a expensive temperature controlled soldering Iron like Weller for example. what is the difference between this: http://www.banggood.com/Mustool-MT223-60W-Adjustab...this: http://www.banggood.com/110V-220V-967-Electric-Rew...and the project just described above, they all temperature controlled, people say they all good. Leaving aside the joy of creating something from a scratch, would there be any advantages for owning a station instead of small temperature controlled unit?
I wander if this works for A1469 think this is 3th gen.?
I am thinking of soldering the pennys
