Yes, 220 and 240 volts are a nominal figure in the same voltage range. It is brought about by the power company, as they have a responsibility to keep voltages within a certain 10% range. The load will only notice a difference of 1% on the load current. eg. Wattage load of 2400. Amps = watts/volts. 2400/240V = 10 amps. 2400/220V = 10.9 amps. On a constant resistance as the voltage goes lower, the current goes higher and vise versa as the voltage goes higher, the current goes lower.

It can be done but not recommended. Check on the nameplate of the welded to see if it is a dual voltage machine. By running the welder an a lower voltage than the manufacturer recommends will throw off all of the heat and DC volt settings that are used to govern the heat of the arc.

yes most welders have several voltage inputs, as long as it is a single phase it will work fine

How big of a generator do you need to drive a 200 amp welder?

When you refer to a 200 amp welder you are talking about the output side of the welder. What you have to do is find out what the input voltage and current of the welder is to calculate the size of a generator needed to operate the welder.


What size wire for 220 air conditioner heater?

Without the amperage the device uses this question can not be answered. The size of wire depends upon the amount of amperage a device draws. The voltage is independent of the size of the wire, it is an insulation factor. Most commonly used wire is rated at 300 volts.


How many Watts will a portable diesel generator have to produce to run a Lincoln Tig 275 Welder at full power?

Your welder needs 20A at 120V for full output. This is 2400W, but you should always add a little extra margin, so I would recommend a 3600W generator.


Would using a 200 foot extension cord which is 6 gauge 3 wire cord on a 220 single phase welder present any problems?

Absolutely, you will have voltage drop, maybe enough voltage drop that the welder will not work <<>> To do a voltage drop calculation for the 200 foot cable the input amperage of the welder needs to be stated. At a maximum distance of 201 feet and limiting the voltage drop to 3% or less, a #6 copper conductor can deliver 37 amps on a 220 volt system. Check the nameplate on the welder to see if it falls withing the range of 37 amps input amperage. Do not use the welders output amperage.


What size circuit breaker is needed for a 190 amp welder?

The size of the circuit breaker and the wire that will feed the welder is based on the amperage that is needed by the welder. The voltage only explains what the insulation factor of the wire should be.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

How do you Connect 3 phase water heater to single phase?

Most 3-phase welders cannot be made to function on single-phase power. If your welder is an inverter type, such as a Miller Dynasty or Lincoln Invertec, then it may have a single-phase mode with reduced current output. You would have to download the manual for your particular welder. If it is an older transformer (big and very heavy), then you're probably out of options here.
