Bird, I also learned on the Lincoln 225 in high school ag class a LONG time ago.
For the few of you who have never done it, just picture a flashlight shaped handle with a little clamp on the business end, where you clamp a metal rod about 12" long perpendicular to the handle. You then close your helmet (like shutting your eyes), try to remember where exactly the piece to be welded is, and then try to strike the rod on the metal piece that you can't see, but never get more than 1/4" or so away from the metal, then maintain this 1/8" or so distance away from the piece during the weld, while breathing noxious burning fumes and being bombarded by white-hot metal fragments.
If you strike to hard and get too far away, no arc, and if you don't strike hard enough the rod gets stuck to the piece you are welding.
I've never done mig, but I'll bet its a whole lot easier.
