Generator sizing?

I have a welder which is a 150amp and i need a generator which can run this power. can some one tell me of what kVA im going to need for this, i believe that 45kVA would be okay but can some one see if im right. alternatively can you tell me the Watts that would be needed on a 230V single phase system.

I have used the following link to check some data but im not sure if this is correct

Thanks for your help.

You are correct that 45kVA would be 150 AMPs. You probably should think about oversizing the generator for the surge that happens when the welder is first turned on.

The 45KVA is for 230 for 110 volts you would need half of the 45KVA or 22.5KVA

At least that is the way it calculated for me using those tools.

So pretty much you need a generator that can deliver 150 amps. Wow that's a lot of current!
