Juan, Steve, et al,

If you do a calculation, you may find that it is difficult to change the tin % by adding solder bars. I did some calculations some years back and was amazed at how much solder you'd have to add. That was for a wave solder machine, and it sounds like you have a big solder pot.

Subject: [TN] Solder bath analysis. Sn63Pb37 alloy.

I have a question about the variation of the tin content in the solder 
alloy and I'm sure that somebody will explain it me.

Why the tin content decrease more than 1% from the nominal of the 
Sn63Pb37 alloy? May it be by the dross...?

I suppose that it will be neccesary to add pure tin. Is it correct?

Thank you for your support. Kind regards.
