Of course it is physically possible. However, I strongly suggest you check with a qualified electrician who knows the particular electrical and building codes for your area as they can vary. Done incorrectly, you run the possibility of electrocuting yourself or someone else who uses that outlet, or setting your house on fire.
A 6-20R is 220V, 15/20A correct? If the outlet is within 75ft of the panel you need to run 12-2 to the outlet from the panel. I would recommend 12-3 as you can then upgrade to a 120/240V outlet later and you are not using a white wire as a hot. If you do use 12-2 wrap the white wire with electrical tape to show it's not neutral. Then just wire the outlet as a normal 220V outlet to a 20A 220V breaker.
No. You can't replace a 220V outlet with a 110/220V outlet without running the requisite neutral wire. If you do you will blow out any device that expects the neutral line to be connected.
Make sure the wire size of extension cord is AWG 12 or AWG 10. Also circuit must support the 20A at main panel. Standard household extension cords are usually AWG 14 which are not sufficient to carry 20A.
If you have 12/2 wiring in this circuit and a 20-amp breaker controlling it, you can THEORETICALLY do it, but you've got another problem: according to code, if you've got a 20-amp breaker and a 20-amp outlet, you're only allowed to have one outlet in the circuit on the theory that a 20-amp outlet is going to have a 20-amp appliance plugged into it. If you want more than one outlet, you'll need to use 10/2 wire and a 30-amp breaker.If you are asking this question, it implies you are not qualified to do the work. Hire a licensed electrician!If the breaker is not already 20A, then absolutely not! An existing 15A breaker will have #14AWG wire to the outlet(s). For a 20A circuit, you must have a MINIMUM of #12AWG. If you try to push 20A through #14 wire, you could start a fire, not to mention it is illegal.15A and 20A outlets are wired exactly the same, one just has a higher rating than the other.A regular 120V outlet is already single-phase.So, your question really is: Can an existing 15A, 120V circuit be converted to a 20A circuit by simply changing the breaker and receptacle to 20A? : No, the breaker, wiring, and receptacle(s) must ALL be changed to be safe and legal.If the breaker is already 20A, and the wiring is already #12, then no modification is necessary. You are good to go as-is.Tip: If your house has an outlet for a washing machine, check the breaker for it. Washing machines are supposed to have their own dedicated circuit, and that circuit is required to be 20A according to NEC article 210-11. You could use that outlet temporarily to do your welding.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.if the wire is #12 or higher, then yes you can swap the breaker and receptacle. however, without ripping your drywall apart there is no guarantee that is #12 the entire run. back to your panel. if ihe wiring is open and you can verify its indeed 12 gauge....go for it.
The only way you can change a 15 amp to a 20 is you have to replace the 14 gauge wire going to it with a 12 gauge wire, then replace the 15 amp breaker with a 20 amp breaker. You can put a 15 amp outlet on a 20 amp circuit as long as there is more then one receptacle. A double receptacle counts as two receptacles. Steve Green Coeur d'Alene, Idaho

120V, but 20A, so not a regular outlet or wire.
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.
Yes but you will not get the full watt rating out of the tank. Watts = amps x volts. Say the tank draws 20 amps. 20A x 240V = 4800 watts. 20A x 208V = 4160 watts. It will take longer to heat your water with less wattage.
12 AWG.
You have to replace the wire (as you are increasing the current capacity), the outlet, and the breaker. Essentially you have to remove the old circuit and put in a new one. You can't reuse parts of the old circuit as you are increasing the current capacity and they would be underrated.
if the outlet is 20A it's ok on a 15A outlet depends what you what to run it may be too much.
There is no problem at all. It is the breaker that protects the wire and limits the current to 20 amps. Voltages in most supply systems vary depending on the time of day and where you are situated on the line in the system.
