What's the reading at the service panel? What do regular 115V outlets read at? What kind of meter are you using? Chances are you have 480/277V 3 phase power to this building. Whoever wired the outlet used a 277V feed, possibly because 240V was not avaliable. You should call an electrician, repair of this problem may involve instalation of a transformer.
You cannot plug a 240V appliance directly into a standard 120V outlet as it can cause damage or be a safety hazard. You would need a dedicated 240V outlet and possibly a step-down transformer to safely use the appliance. It's recommended to consult an electrician for proper installation.
No, a 240V 22A welder requires a 240V outlet for proper operation. Plugging it into a 120V outlet will not provide enough power and could damage the welder or create a safety hazard. It is important to always use the correct voltage and amperage for electrical appliances.
For a 240V outlet, you should use a fuse that is rated for 240V. The fuse's amperage rating should match the amp rating of the circuit and be appropriate for the connected devices. It's important to use the correct type and rating of fuse to protect the circuit from overloading and electrical hazards.
No, it is not safe to plug a 120v 20 amp welder into a 240v 40 amp outlet. The voltage difference is too high and could damage the welder. It is important to match the voltage and amperage of the welder with the corresponding outlet.
Yes, you can install a switch to turn off power to the 240V outlet that your window AC unit is plugged into. This can be done by installing a double-pole switch rated for 240V that interrupts power to both hot wires simultaneously. Be sure to follow proper electrical safety guidelines and consult with a licensed electrician if needed.
Disregard the neutral

You will burn up your appliance!!!!!

You can, but be advised that whatever you plug into the new outlet should not exceed 5000W capacity (20A x 250V = 5000W)or you could risk overheating the new outlet with serious results. To prevent this, you should make sure the circuit breaker is a 20A also.
If you don't know that then you shouldn't be messing around with electricity. It's dangerous.
Don't!
Off hand no but your explanations are not clear as to who is doing what to whom,,
