Works like a beast. First I bought 140FC-i but then I wanted to upgrade. This also applies to MIG and Stick welding. It also works with TIG, but I don't see myself using that feature. If you look at 140FC-i and 140MP, buy MP. The other big improvement is the entire delivery system, it's all metal and built like a tank. The 140FC-i feeding system is made entirely of plastic. Both work great, but I wish I could buy the 140MP right off the bat. That would save me a lot of money. I also have some good quality INETUB flux cored wire and that seems to make a big difference too.
