Jody, you talk about using Ar He 50/50 mix for aluminum. Why won't this mix, or something similar, work for both processes? He was the original shielding gas for TIG. Hence the name Heliarc. I personally have used straight He as a shielding gas when MIG welding and it worked fine. So why not some sort of a mix for both?
I'm not trying to cause trouble and if there is a good reason I'd like to know. Like the other fella, I'd like to have only one tank to keep track of as well. Thanks.
