Plugging a lower drain machine into a higher drain outlet is perfectly fine, the outlet will be able to deliver all that the machine needs. And the machine will only use up what it needs, so having excess at the outlet isn't going to hurt anything. The other way around, a machine pulling more than the outlet can deliver, will trip the breaker or blow the fuse.
The four blade dryer plug brings a separate ground wire from the machine to the electrical grounding system. The three blade dryer plug depended on the neutral wire of the plug to make this connection.
It may work but will probably surge it...power coming in from both directions
You would have a code violation, only a 50 amp/250V plug would fit into a 50 amp/250V receptacle. You would not have proper overload protection, the load could (worst case) call for more amps than it is rated for and catch fire before the breaker tripped.
This is a special purpose outlet, likely for a dryer. Normally in a house electric panel you have 120 VAC as the normal and 220 or 240 as a higher voltage. The 30 A is for 30 Amps. You can only plug in an appliance that has those ratings. You can't plug in a 120 V device.
No, a 20 amp machine should not be run on a 15 amp plug because the plug is not designed to handle the higher electrical load of the machine. This could lead to overheating, tripping of the circuit breaker, or even starting a fire. It is important to always match the amp rating of the plug to the requirements of the machine.
A 50 amp welding machine requires a 50 amp welding plug, which is a specific type of electrical outlet designed to handle the high power needs of the machine.

Well it depends. An outlet will spark when you remove a plug if the machine is still on, so make sure you turn the thing off before you pull the plug out.
You will burn up your appliance!!!!!
An outlet with too many volts in it or a short.
When installing a washing machine plug, make sure to follow these precautions for safety and proper functioning: Ensure the plug is compatible with the washing machine's power requirements. Use a grounded outlet and avoid using extension cords. Check for any damage to the plug or outlet before installation. Make sure the plug is securely inserted into the outlet. Avoid overloading the outlet with multiple appliances. Keep the area around the plug clear to prevent tripping hazards. If in doubt, consult a professional electrician for installation.

It is likely broken if there is power to the outlet

The device requires a NEMA 6-50 outlet, which is a specific type of electrical outlet that can provide 240 volts and handle up to 50 amps of current.
That happens when the appliance supplied by the outlet is switched off.
The voltage in a UK outlet is about twice that of a US outlet, which means you could ruin your sewing machine trying to plug it in. In order to use your US sewing machine in the UK, you'll need to purchase a voltage converter (transformer), and then you'll need to buy a UK adapter (since the transformer plug doesn't match UK outlets).
