Hi guys
Hope someone can help I am making own wedding bands one 3-4mm wife 18k for her one 9k 7mm wise for me I have both solders but 1st time I soldered I melted side of ring I figured I got everything to hot (torch nozzle was wrong) so now I have a cooksons butane Hans Held torch seems hot enough and yesterday cleaned well solder flowed perfect and seemed to work but after clean the solder melted just beside the join not in it -
What’s am I doing wrong - I had this a couple times now solder flowing beside join not in it
- the rings still perfect so I can try again - do I need to file off old solder or will this remelt and go in the join

Any help appreciated
Thanks Mark
