Slag, Sorry for the late reply, I just saw your question. A portable may be your best option, plus you'll have a generator if the electric goes out at your house. Miller, Lincoln and Hobart are three common ones that can provide size/type welder you need. I have a Miller Bobcat that's 25+ yrs. old that handles anything I need to weld and used to be my emergency generator for the house, ran 9 days straight after Hurricane Gustav. I loaded it in the back of my Polaris Ranger six years ago so I could get 8 miles in the woods to a dozer, with a broken C frame, and weld it back together. Must have done a good job because the dozer is still running and everything is holding up. I wish it was one of the newer ones with CC/CV so I could run Mig off it, but until it shuts down it wont be replaced.
