For a first time welder, I highly suggest staying away from anything that is 110v or stick...
There is a reason it's called "stick" welding...
Not only do you use sticks, but you also have a lot of "sticking" of the rod to the work...
I have been through a welding school, and believe me, there is more to welding than just melting steel...With the stick welder, you have very fussy variables like: Rod angle, arc distance, travel speed, temperature of the metal, rust / no rust, welding rod diameter, type of welding rod coating(flux), etc...
A MIG welder is very user friendly...
.030"-.035" dia. wire will weld anything from thin sheet metal on up...
3 adjustments only...Wire speed, heat, and CFH flow of the shielding gas...
Also, remember a big enemy to a nice weld is GRAVITY...
Imagine you were trying to push warm runny toothpaste into the gap your trying to weld...
Don't try to weld upsidedown or vertical, until you are more experienced with the machine...
Move your work, not your welder...
Keep the work flat or on a workbench as much as possible, and make yourself comfortable...
The extra effort you put into comfort and work position will show up in the quality of your welds...
I can also say "Bigger is better"...
A larger machine running at 20% of it's capacity, is FAR more efficient and welds nicer than a small machine that is maxxed out...
I'd say go with a 220v wire feed welder (MIG) without a doubt...
Go with an industry recognized name brand like Miller or Lincoln too...
Just try finding tips or parts for the MIG gun on a "no-name" welder...
It's definately worth the added expense to get a better welder...
You may even want to upgrade with a TIG setup at a later date, and the TIG stuff will NOT work with a junk welder...
You would be amazed at how sweet the welds will look after a little practice with a good MIG or TIG welder...
There is a ton of good responses in this thread, read all of them...
Good luck !!!
