Getting 240v out of 120v generator sockets?

I have an 1800 watt generator with two 120volt sockets and I want to run a 240v welder off of it. Is this possible? I'm not very familiar with elictrical components. Can I buy a step up/ step down voltage converter? I see them all over Amazon. Thank you

No.... an 1800 watt generator is strictly a 120v generator. It's not going to run a 240v welder.

It's really too small to even power a small step up transformer that could power the welder.

Will it have any issues powering a 120 volt arc welder?

Even a small (80 amp) arc welder will likely draw more than the 15 amps that generator can provide at 120 volts. The smallest harbor freight model specs 20 amps at 120 volts input. You might get by with it for very light welding at low duty cycle.

How about an 8hp 4400 watt generator with 2 240v outlets? Will this power it?

Depends on the welder you plan to use. Have you considered a diesel or gasoline welder?

That's 18A of power at 240v. What does the welder require ?

The owner says all that he knows is it says 230 volts and 60 hertz. It's a Lincoln 230 mig welder.

I wish I could find a gas or diesel welder for the price I'm getting ready to pay for this Lincoln! That would be perfect.

The 230 refers to voltage. we need the model number. Doing a search for "http://www.lowes.com/pd/Lincoln-Electric-230-Volt-MIG-Flux-Cored-Wire-Feed-Welder/1072947" this as close as I came. is this it? Shop Lincoln Electric 230-Volt MIG Flux-Cored Wire Feed Welder at Lowes.com

That looks similar but is a newer version. His is quite a bit older.

Then we need to know the actual model number or how many amps full load on the 240 side.

Are you sure..... 90A at 240vac would be a massive welder.

I would expect it to be something like 20-30A at 240vac.
As I previously posted your generator can deliver 18A at 240vac so you'll be lacking.

90 amps sounds more like the output of the welder than the input which is what we need.
