I bought one of the longevity weld/plasma/arc welders a couple years ago with hope, but what I got was a machine that failed exactly a week later after getting it. It worked good then one day i fired it up to cut some 16 ga steel and there was very little spark. I had the correct air, proper ground, settings, etc etc etc. In the world, you get what you pay for. If it sounds to good to be true, it usually is. Long story short, I spent the extra 300 bucks and went with Miller; they have excellent customer service and warranty, wow what a concept! for a little bit more, you get something that is made here and has also a way better resale value.
