Awesome wife!

I'd say that you have the little woman trained up pretty good!
That welder looks like a good one, just get you a bottle of gas and a spool of mig wire to begin with and you will be in business.
I have a small Lincoln like this one and it does what I need to do. The few times I had a thick piece to weld, I fabricated and tacked the project together and then carried it to a welding shop for a good hot weld.
