I got hooked with a welded WRA back in the 1980s, it's a bad feeling. What to do with it is a matter of conscience. Most people try to pass it on, but I was lucky in being able to turn it in to the Rock Island exchange program before I had to wrestle with the problem. Even if you sell it cheap with the disclosure that it is welded, the buyer will probably mark it up and resell it as legit.
