I clicked on Amazon and there were overwhelmingly favorable reviews for the machine. You could probably get really familiar with it by watching many of the Youtube videos. It should be able to do the job. I'd wirebrush the heck out of everything first off, to remove rust and crud that doesn't conduct current making starting and a stable arc tough, as well as removing potential contaminants.
My first concern is seeing it is 110V as you may make frequent trips to the breaker box. As you'll be working at a lower power load with small diameter wire, low voltage and low current, you may luck out. Try to avoid using an extension cord, or at least make it a really heavy one. Too much heat/wire feed speed and you'll know it, as it'll blow holes instead of form welds... that's what you'd get if you tried to stick weld it. You MAY find the flux cored wire is very similar in heat to stick welding and that too could make swiss cheese out of the underbelly; that's why I suggest using CO2 gas and the regulator. Practice on some scrap metal to adjust your wire feed speed and voltage adjustment and get a good feel for it. It only takes an instant to pull the trigger and make sparks, but it'll take a great deal longer to remove dingleberries and patch holes. You may discover that you're more successful making a series of connected short tacks (stitch welding) rather than long continuous welds- less distortion and fewer holes. It will take some time to feel it out.
We've purchased 8 CRXs over the years, and living in Michigan, our three 1st generation CRXs have had bad cases of cancer underneath from the salt, BUT our last one is the Straman which we picked up in Los Angeles............. ROCK SOLID! Lucky me!
