Sorry Vince I didn't see your post --- weird --- sometimes Lat G doesn't send an email with a post in a thread I'm following....
So when you say it changes color --- it depends on what color it's changing to. So the best way to answer is for you to have a reference to go to which shows various bad and good welds -- aluminum - chrome moly - and stainless steel.... so just scroll down and see and compare.
