Okay, I'll partially take that back and say I have never used one. But I have tried out there helmet and the shade is not uniform darkness and that scares me, a lot. Inside the welder, all the drive parts are plastic, not aluminm like a Hobart or something. Getting parts for them I've heards is very hard. The wire is always live whether you are pulling the trigger or not: very dangerous and difficult to get close to the workpiece before starting unless you use an autodarkening. But, they are affordable. BTW, ever tried aluminum wire with an HF welder? Just curious. I want to see what's the cheapest way to effectively weld aluminum without borrowing equipment or having someone else do it.
