I just ordered this. A friend of mine has one. For price it's not bad. Most time I don't have help to keep stuff in place while welding. Theven auto darKing is nice so you can use both hands so can keep stuff in place while tacking. Especially smaller pieces, and tight places where hard to get a support behind it.
