It should work. May be to hot for thin metal on TIG.
Linde used to sell Ar/He mixes for MIG/TIG. They did not have the trimix gasses. After the Air Products buyout, I think they still available but you have to ask for them. Here everyone uses 75/25 (short arc) or 92/8 (spray transfer) Ar/CO2 for MIG.
Not sure about stainless. You do not want much CO2 due to carbon being added to the weld. Here, Ar/O2 mixes are used often.
I have never seen any negatives posted on Ar/He mixes for MIG. As they are more expensive than Ar/CO2 mixes, they are not popular. The gas mix uses are dominated by high-volume industrial uses where cost is a big factor.
Would be hard to say how much He would be right. He reduces the arc stability as does CO2. Hard to say the right mix. I seem to recall 15% He was used for MIG.
