I have run a couple of pounds of these rods. I'm decent at the welding part, the rod feeding part was holding me back. I felt at home with the controls, they are almost identical to the 255EXT. But watch the pricing, it changes regularly. Construction is strong & feels like the kind of thing that will last years.

Uniweld 40077 Final Thoughts
"He was showing off!"
I needed to hand carry in my luggage. I have a small machine shop and build tooling often. A powerful Arc Welder that gets the job done even at 120v. Not so convenient if you are welding up a table or frame. This thing is totally AWESOME!
