What is really amazing is welding with a 220 3 phase. I was blown away with it at a shop I worked at with one. You could just about weld thru grease or something, it was amazing. From what I understand about it, as you mentioned the 110 is harder because it is one "wave" of current, while 220 is two making less of a "skip" from one arc to the next. The 3 phase gives you three, so it's of course even better.What are you trying to learn on... If it's a 110 unit,, It will be harder to learn on....The right machine has a lot to do with it...I had guy's come to my shop that bought some small machine and was having a hard time learning,,, I took about 15 Mins on my machine with them and they couldn't believe just how much better they was in ONLY 15 Mins..
