I know that Mark is a very qualified and experienced welder, and he has cautioned me once over the phone and once in a post about the dangers of titanium welding fumes. I'm not doubting the man, but I also could not find any supporting evidence on the topic. I thought it prudent to start a separate thread to clear up my confusion rather than hijack someone else's

Would there be any advantage to using a helium mix instead of pure argon?
