How many "solder masters" are on this discussion group? I've seen some mention of newer types of solder (lead free?). I've also seen mention and used one type of water soluble flux (BTW, I really liked it). I've been using Kester "44" .031 solder for years (for small work). However, I've got a project that I'd like to have every advantage possible (as far as having good, clean soldered connections). Does anyone have any suggestions? I wonder if the lead-free stuff has a higher melting temperature? BTW, I'm using a WTCPT soldering station. Any tips would be appreciated. Thank you, Robert Greenstreet
