I use Cardas Quad Eutectic in all my work. It flows and works beautifully and produces great looking solder joints. The newer Cardas solder without lead doesn't seem to work as well. I would try to get the older "Quad" formulation.
Silver solder--what wattage soldering iron?
I need to solder some new Cardas cartridge clips onto my Rega RB600, and I'm having trouble using a Radio Shack 40W soldering iron with the silver solder that came with the clips. Doesn't seem like I'm getting enough heat, even after I cleaned the tip with sandpaper. Does this iron have enough wattage, and if not how much do I need? Thanks, Will Herrera
