Bev, Howdy partner from the moonman in BF Montana again. Know little about tin cans but for those housing Bud. Hell, that's aluminum and I know how those cans are formed after having served time at Coors as an automated brewing process engineer - whoops! I know this doesn't answer it and I know you know this but I have too much time on my hands. Soldering iron tims are made/formed/extruded from copper as wire. They are properly shaped and plated with a "neutral" metal as iron - to the soldering process when prevented from oxidizing by being properly tinned. Properly "tinned" tips, the iron part (1 mil thick iron plating over copper), ensure acceptable solderable surfaces provide they are cleaned and re-tinned as often as needed. Jeez, why am I going on with this as you are only asking about tin cans. Could they be soldered using the same concept. When you get a "real" answer, let me know and thanks again for all that Nortel info. It, and the contacts you provided, really did the trick. Wish Nortel was in better health.
