Ahah, thanks for the hints: learning is a never ending process, no matter the field, and I’m always willing to improve myself 
I actually have been speaking English every day since childhood but sometimes when it comes to technical terms in fields I’m not used to move into (this is the first time I’m actually writing a post about soldering for instance) I might mix something up.
(Like this for instance, ‘solder’ in Italian is the actual torch)
All of this (excessively long) post comes down to me expressing my gratitude toward this amazing community full of people willing to help and share.
