15 cubic inches should be accurate.

If you're using something like the instructions will state it needs a 2 gang box or similar, and not to be installed in a single gang box.

There is another black self contained outlet that i cannot upload an image of here for some reason. The reason i chose this one and the need to get the right box for it, is i am also running electrical pvc down the wall to it and that fixture only has one way conduit will attach to it except from behind.
The welder’s cord points down and the cable would point up and by putting the other in a 2-gang box, i can rotate it 180 degrees to accommodate the power cord how i want it so it would hang down properly. Hard to describe.
