What does the Outokumpu welding guide recommend for 2205 to 304 welds?  Check there first.

For your purpose type AWS 309 Mo with low carbon content,is better choice than SA 304.

It's a dissimilar welding, but there are no particular problems. Just foreseen a buttering with 309 electrode on the 304 and then complete the welding.
