Straight CO2 compatible?

Yes this gauge is compatible With C02

Do I still need to buy a solonoid if I purchase this regulayor?

I’m sure you don’t have to purchase a solonoid. This is a regulator it regulates the gas flow manually.

What is the fixed output pressure when gas flow is cut off at the welder? Please don't answer regarding flow adjustment.

This is a flow meter, not a regulator. Your output will be equalized to your tank pressure.

So, there's no way to regulate output pressure? Just flow rate? So as tank pressure drops, flowrate goes down?

yep, adjust flow rate accordingly. Not an issue with an industrial sized tank.
