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.

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.


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.


Will a 800 watt generator have enough power to operate a 90 amp welder?

No, unless you can set it low and can be assured that it wont use more than say 4000watts, the welder might momentarily use more power than what you set it to, it should not wreck the welder i would imagine unless it is a fancy mig welder or something, set the welder low you should be fine but for high end use she should be firing out 8 or 9kw so keep it low if you must.


If my house has a 200 amp line what size generator would it take to run the house and have the same power?

Your house runs nowhere near 200 amps, so you need to make a list of appliances and fixtures that you use, or that you will need while the generator is running, and add their power consumption together. Add some extra capacity for growth and so the generator is not always at full power. Then talk to dealers about generators with the amount of power you need. To run the house on a generator with the same capacity as the service that you have in your house you would need a 50 Kilowatt generator.


Do you need an electrician to install a portable generator?

Yes, you need an electrician to install a power generator and it is very important that he is licensed otherwise it would not work/is not legal. Hire the licensed electrician to install a transfer switch.

Is a gas generator better than electric?

The purpose of a generator is to generate electricity. An electric generator would be redundant. It would need electricity to make electricity and when there is a power outage there is not electricity.

What size generator do you need to move a 30 hp electric motor?

A 5 kW generator would turn it over but if the full 30 hp of mechanical power is needed, that would require about 30 kW of electric power from the generator.


How do you calculate power use for a home power generator?

Click the link. There you can figure the size generator you need.


Does a back up generator need initial electricity to work?

No, a backup generator does not need initial power to work. Once it senses that the main source of power is cut off, the control will send a signal to the generator and the generator will kick start and provide electricity until it senses that a stable power source has returned. Then, it would switch off and be on standby mode again.

What is the best power generator for home use?

I would recommend a Generac, though these can be more expensive. Have you determined the desired fuel source (diesel or propane) and the amount of power you would need in the event of an outage? Without this information, buying a new generator is not easy.


What kind of power generator should I purchase for my home use during an emergency?

The power generator you buy depends on the amount of power you need to generate. On Walmart.com there are several generators listed with various capacities. Be aware of the safety precautions you will need to take when using your generator.
