I got some dual shield wire from Boeing Surplus. The data sheet with
it indicated that the wire was intended to be used with CO2. It works
well for me . The dual shield tolerates slightly rusty steel.

CO2 is a hell of a lot of shielding gas.
It makes a hotter arc, penetrates deeper, splatters a hell of a lot
more and makes a narrow bead.

But its cheap, and most of my welding is done on rusty steel pipe,
channel and plate around the homestead. Rough and ready utility
welding where cosmetics is not an issue.

I would hope others here would chime in and tell both of us the
plus's
and minus of using straight co2 for this sort of welding
