You would need at the minimum a 56 KW generator. In reality you would need a 60KW.
Generators are rated in watts or kilowatts. The formula for watts is W = Amps x Volts. To size a generator for the welder the voltage of the machine must be stated.
The size of a generator is based on what the connected load will be. Add up all of the connected wattages that will be connected to the generator at one time and add ten percent, this will be the size of the generator you will need. Some equipment does not show the wattage on its nameplate. To find the wattage use the following formula Watts = Amps x Volts.
Check the wattage of the blow dryer and add 500 watt. This will be the size of generator you will need to use.
The average size water tank is 4500 watts. The generator's supply will be large enough to operate the water tank. Larger tanks over 5000 watts will not heat correctly.
The size of the generator is based on the size of the load you want to supply. Size up the load in watts or amps along with what phase (single or three) and voltage that the load requires. These are needed to give a complete answer.
If it is a portable generator the breaker should be self contained within the generators panel. If the generator is a stationary standby unit a voltage has to be stated to calculate the conductor size and hence the breaker size to protect the conductor. Amps = Watts/Volts.
There is no way to answer without knowing the wattage rating of the 9 volt generator. A generator's wattage rating depends on the size of the wire in it, the wattage of the rectifiers if it is a DC generator, and the horse power of the engine or motor that is available to turn the generator.
Answer Generators usually always go by watts. To figure this all you do is take(volts x Amps) = watts. You know the volts (220) then look on the pump for the amp rating and then multiply them and you will have your watts. Then get a generator that is rated for this amount for continuos operation not peak watts. Hope this helps.
Conversion from gas to electric should be 750 watts/hp So 7.5*750=5625 watts These are running watts so that is a bare minimum. Depending on the application it needs much more starting watts (up to 3 times for a compressor). Generator should be no less than 8000 watts, maybe more if you work it hard.
There is a calculator that helps determine the size of generator for a specific application. The kilowatt is a thousand watts which is also is the same as one KW.
At 240 volts, and 7 amp current, you will have a load of 1680 watts (volts x amps = watts). A 2000 watt generator will sufice, however a 3500 watt generator, if within your budget, will power a few other necessities if required.
you need around 60000 watts on a dc current
