I saw an ad in Craigslist today that said, "Lincoln welder $1." I called the number, and sure enough, he said he would sell me a Lincoln 250/125 AC/DC welder in excellent condition for $1.00. I went up and got it, and he threw in 50+ pounds of welding rod to boot. He said he bought it new, and just wanted to get rid of it. I didn't want to ask too many questions, so we loaded it in my van and I hit the road. I haven't actually tried it due to the rain, but I'm not really worried about my investment.
