Design Recommendation on a welding machine...?

The ideal welder is Lincoln's 110V "nascar" for no gas welding, you want one. 30 years of flux center line. It's not a machine designed for professional use, but I think it will suit you. We have one in the store. It's useful in a pinch.
I'm not sure which welder you're talking about, but most of the miller and Lincoln in the market are last, and the prices of these machines reflect that. If you're talking about some cheap hardware stores, especially with a recognizable name, I'll say it's not worth it.
