I would definitely shy away from inverters, a blown board will cost as much as a new machine. I'm a union steamfitter and pipeliner, and have burned up several over the years, most of them repeatedly. If you want to spend money, buy all means do so, but that's not where i would spend it. A buzz box will do what that thing does, and will last long enough that your grandkids will be able to use it when you are long gone. Spend money on a victor journeyman torch, a 6" makita rat tail trigger grinder, or bigger torch bottles.
Inverters don't run 6010 worth a damn until you step up into industrial machines of 300 amp or more, and even then it's iffy. So you will be running 6011, 7014, and the like. Low hy rods are overkill for most applications, and unless are stored in a rod oven their whole life aren't low hydrogen anymore. Most of what you will find online or in stores is pure bs propaganda, welding is actually very simple when you separate fact from fiction. You need heat to weld, mig doesn't supply enough till you are in spray transfer (3 phase or 100 amp input), you don't need advanced stuff to do what your grandfather did in the barn with simple tools, which are still in production for a reason.
Seriously man, any questions you have i would be happy to help, and so would many others here. Buzz box to start, 6011 rods. You won't need a super fancy hood either.
