TRT Wonder Lead-Free Solder
NOTE from TRT leader, Pete Moncrieff:
"Signature Solder employs different, premium metallurgy for more transparent sound, same melting point, as regular wonder solder. melting point is in high 300's F for all leaded, low 400's for all lead-free.
...but we recommend you use a much hotter iron, 750F for leaded and perhaps hotter (even 800F) for lead free -- this higher temp is not needed to melt the metal solder, but instead is advantage to vaporize the flux instead of merely leaving it in brown liquid form -- in its vapor state the flux does a better cleaning job, giving you an even better quality joint that also sounds even better.
Using this hotter iron also means that you can finish a joint with less iron dwell time on the joint, so the total heat input to the joint might actually be less than if you had used a cooler iron temp."
