I absolutely love my YES Welder. Ordered it on Amazon. Lots of reviews on YouTube. It was very easy to setup, works with both gas and gasless(flux) wire. I have only used it with gas. It will run on 120 standard outlet, or 220 if you need max output. It's super portable. I have a small tank so I can grab this, throw it in my trunk and roll anywhere with it.
Below is a link. It also comes with a stinger to do stick welding. It will even do tig (DC Only) if you buy the torch setup, but I already have a Miller Syncrowave 250 for that.
