as far as the argon/helium mix on thinner aluminum: the thinnest aluminum we use is 1/8" so I can't really tell you how it performs on anything thinner. I do use it when making stainless steel electrical boxes. They are made from 16gauge 304 stainless. I just do fusion welds for all the outside corner welds with no problems at all. I havn't noticed much of a difference on the stainless work, but I would recomend the mix of gases for anyone doing aluminum, regardless of their skill level. With the helium in the mix the bottle empties slightly faster, but barley noticable, and I think there was about a $15 add in price but still well worth it.
No announcement yet.
