If you can't post a pic of your 40A outlets
Ground and neutral are not the same, even though they are connected at the first point of disconnect.Because my only 240 circuit is fed from the Main Panel both the Ground and the Neutral are landed on the same Buss Bar. If they came from a Sub Panel they would be landed separatly then I would use a fourth conductor for the neutral.
What does your 240 circuit feed? Since it's a 240 circuit, you don't need a neutral. A 120/240 circuit needs a neutral. And all of them need a ground. Makes no difference if the source is a sub or a main panel.Because my only 240 circuit is fed from the Main Panel both the Ground and the Neutral are landed on the same Buss Bar.

I have a long cable that I use to power my Arc Welder and Table Saw. The cable has a receptical that can take the plug of either the Welder or Saw, but not both at the same time.What does your 240 circuit feed? Since it's a 240 circuit, you don't need a neutral.

Neither of those need a neutralI have a long cable that I use to power my Arc Welder and Table Saw. The cable has a receptacle that can take the plug of either the Welder or Saw, but not both at the same time.
you are correct, but the third conductor grounds the equipment.Neither of those need a neutral
