Seems the Herald360's post has been deleted. Don't worry, that's one of the reasons why I love this forum. I can improve my English too.

Edit: As you have answered this I've reinstated it to make sense of the conversation.

About the cold junction ("soldadura fría"), I just translated literally, the term that we usually use to refer to that. I know about thermocouples junctions, being myself a metrologist.

In fact I'm not sure that it should be a dry junction, cause what I have seen on most Soviet stuff (and recently on Chinese stuff), it is that the junction between the piece and the solder gets oxidised, and they fail to make electrical contact. I think it should be a chemical reaction between the metals and the flux.
