1st time welder

ATM I have a Hobart 210 which is 220v.It welds nice.I have been useing the flux core but you have to watch the heat build up as gas cools the weld down a little over flux.Having been welding for a few decades (on heavy metals) I can say get the biggest you can afford because you will want to upgrade.My biggest advice for a novice is to start with the flux and learn to weld on that then move to the gas when desired.It's alot cheaper to burn thru a couple rolls of flux than burn thru the wire and the gas as you learn.
