The equipment itself can not be converted as it would mean rewiring the motor to operate on 240 volts. The cost factor for a rewind would be too high. The amperage draw for this type of appliance is on the high side, so using a transformer is also out of the question because of the transformer's cost. If you do decide to use a transformer it will have to be sized to the Hoover wattage. Find the wattage of the equipment by multiplying its amps times 110. This will roughly give you the size transformer that you would need if you go that route.
If it says 120/240 or 120-240 VAC or something similar then the indication is that it can operate at either voltage. There maybe a requirement to install or remove jumpers or a rewiring may be required. Check the manual.
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.
This is a two part question. Can a 110v outlet be converted into a 220v outlet, yes it can. The other part of the question needs to be discussed.
Rewiring is easy
Redoing electrical wiring
240 v is dangerous and any rewiring should be done by an electrician who knows the regulations that are there to prevent electric shocks and fatalities..
plug all wires together.
earth your amp
It is possible to convert it to gas, but this isn't a job you want to do yourself as it is very dangerous and involves rewiring of the stove. Call several gas fitters to visit your home and get a quote on what they could do for you.
If there is an INPUT connection, YES. If not it would be possible but would require some rewiring by an expert.If there is an INPUT connection, YES. If not it would be possible but would require some rewiring by an expert.
If you have some coils of wire and a house that needs rewiring, an electrician is needed to complete the job. He/she would also know if the wire you have is the correct wire to use in the rewiring.
More cost effective to buy a new one.
