I believe that a 240v is much better value and far more versatile than a 120v. First I bought a 120v machine which was ideal for about an hour until I decided to weld more substantial steel, so I got rid of it within 6 months of getting it and got a Lincoln 180c and love it. My goal initially was to weld body panels and small steel, of course by the time I finished my first project, I realised that the 120 v machine just wouldn't cut it especially when using a 15 amp circut (fire), in fact I found the 20 amp circut frail as well, so I sold the inadequate machine. Now, with the 220v machine I'm still limited, butit surprised me how much more versatile the new machine is. For thich (1/2"+) material, I picked up a 300 amp stick machine. Avoid financial and creative frustration and go with a 240 volt machine. You are going to have to upgrade your wiring to at least 12ga wire, for just a very few more dollars, you will have a solid 240v circut running a good, solid machine, I upgraded the 120v line to 12ga and then again to 240v, why waste both time and money? Remember, things change in the future and you WILL want to work with more than just sheet. EDIT: Take a look at the new Lincoln multi process machine (MP210?), it may be all you need for now and in the future. Ultimately, whatever works for YOU is where you should go with this. All the best to you!
