First , check what amperage that 220v outlet is wired to handle - it may be only 30 amps which is not enough for a transformer type welder -

Not really.
I've run my Miller 210 (predecessor and nearly identical to the 212) for years on a 30 amp circuit. Max draw right out of the specifications is 29 amps. Never tripped the breaker once.
To me the real constraint is budget. For $1000 roughly, no better choice than the Miller 180 or the equivalent Lincoln, or Hobart. The 211 looks interesting with the dual voltage input. Never used a machine like that, but if Brian says it's good, I'd use it.
The other constraint of the smaller machines is duty cycle. That's where the bigger units shine.
Regarding helmets-the HF one works OK for $50, but the better helmets are worth it. I've used a Miller helmet for the last 3-4 years and other than having to change the batteries once a year it's been great. Much better than the HF ones.
For the original poster, realize this---The welder itself is just a small part of the expense. It's everything else that adds up. From the Helmet ($300+) to protective clothing ($150), to a chop saw, to gas bottles($200) to angle grinders (at least 2, 3 is better-one to grind, one with a cutting wheel and one with a flap disc-- Milwaukee only here, trust me), you end up spending a pile of money to be able to weld, above and beyond the welder itself.
So we're back to...what's your budget? $2000 would be about right for a decent 220 welder and accessories. If you want a heavy duty machine, add $500-$1000.
