None other than being able to plug it in anywhere you want.
If you want to use it around the yard or at your buddy's place, they aren't likey going to have a 220 plug and a $$$ 100' extension cord when/where you need it.
The 211 linked there has both line inputs and pretty close duty cycles and thickness ratings to the 'bigger' unit....so get the one with more options.
edit - added the following after looking for duty cycles -
big one: 160 Amps at 24.5 VDC, 60% duty cycle 3/8"
211: 150 Amps at 23.5 VDC, 30% duty cycle (230 V) 3/8"
90 Amps at 20 VDC, 20% duty cycle (120 V)
I do a fair bit of welding, couple of hours a week on different stuff. I rarely stop and wait around for duty cycle. I'm thinking its just as common with everyone else to do what i do, and just weld until the spark gets weak. With a cool machine to start with, you can blast away for quite a while before its a problem.
And its only a problem on the heaviest longest weld you are gonna run across in our hobby. Most of the time you are fabbing something, the welding is intermittent, you are frigging with setups and tacks and measuring and stuff.
It's just my opinion, but in this case I'd rather have the dual voltage inputs rather than some extra (well, twice) the duty cycle.
If longer heavy welds in 3/8" are what you figure you'll be doing most often, go for the higher duty machine. The 211 is more suitable to home maintenance and automotive. It won't hold you back on the odd thick and heavy job, just take longer.
