Sorry but that doesn't answer my question.
It's impossible for us to advise if we don't know what sort of stuff you're going to be using it for.
If you're intending on welding a lot of 10mm then neither of those machines are up to the job.
Buy an underpowered machine and you will have problems.
I was doing similar thickness stuff and killed a 220A machine due to running it on full power all the time so I now have a 360A mig welder which is single phase.

Sean,
you wouldn't buy a 2nd hand mig without trying it out first, right ?
So, why not set up a demo with a supplier, try the machine out for your own applications and if it doesn't do what you want, walk away (your under no obligation).
When your there open the machine up and have a look at the build quality.
If it does do what you want, do a deal or find a used unit(same type) for sale somewhere else.
Your spending a fair amount of money, so do it on your terms.

also depends on what amps your single phase supply is big single phase migs draw a lot of currant
download pdf looks like 32amp needed or 35amp fuse see pdf

Sorry Sean, you're still skipping over my question as to what the 10mm will be doing!
If it's holding something together then it needs to be welded properly with an adequate machine but if it's just something decorative then hell, you could blob it together with a 150A machine!
It's no good buying a machine that says it can weld 5mm if you'll be using it to weld 5mm, you need to have plenty in reserve.
Yes, it will weld 5mm but not for very long before you hit the thermal cutout then have to wait for it to cool for ages before you can do another short run...cool...run...cool...etc. useless in a production environment where time is money.
Take that Esab for instance, if you were doing production work using 10mm plate you'd be running it pretty much flat out but the duty cycle at 250A is only 20% so theoretically you could be welding for 2 mins then waiting 8 for it to cool.
To get the duty cycle high enough to weld continuously, i.e 100% you'd have to run it at just 110 amps!!
In contrast my Portamig 360 has a duty cycle of 100% @ 270A!
The duty cycle on the INE is much better but I've just spotted something better still......
In Weldequip's shop there's a single phase Portamig 285 ready for despatch, normally there's a 4-7 week waiting list for these so I'm guessing it may have been a cancelled order as they're not usually a stock item.
Even better duty cycle then the INE and cheaper!!

Also don't pay too much attention to what the amperage says in the tech spec, you need to look at the maximum voltage out put from the machine.
Some machines claim to be 250 amps but there is no way that the machine is capable of delivering enough voltage to burn off the wire speed required to weld at 250 amps so it's a bit misleading to say they are 250 amps when in fact the maximum voltage will only really let you weld at 210 or 220 amps "properly"
