When I built my shop, it went in before my house and is also about 150 feet away from the side of my house where the meter loop is located. I just had the power company put in an overhead line to the shop and a meter. This was all free to the meter. If your breaker box is close to where you put your 220v receptacle for the welding machine, you wont need a whole lot of wire so intallation cost is minimal. Later when I built my house, I ran the power from the pole to it underground for esthetic reasons and my contractor put in the ditching and conduit and the power company pulled the wire cheaper than I could buy it. With separate meters, I always know how much my shop is costing me to run which will be handy to have if I should decide to open a welding repair business out of it. I bought an industrial 220/480v 350 amp CC/CV AC/DC stick machine from a fabrication shop for $350 that will also power a wire feeder if I want to get one later, but I like the stick process. It came with over 100 feet of heavy 1/0 welding lead and 50 feet of ground. I next found a used Phoenix 350# electrod oven that keeps my low hydrogen 7018 dry and hot for $150 and stocked it up with 3/32 and 1/8 E 7018. I also picked up a few boxes of E 6010 for running open butt root passes. Next I picked up a Victor cutting torch with 2 oxygen and 1 acetylene bottles for $250 and 3 or 4 each of the 4" grinders for $20 each and a 7" grinder for $40 at Harbor freight along with a supply of grinding disc. Next got a big 14" abrasive cut off saw from Craftsman and and a heavy anvil from a pawn shop along with a 6" table vise and I have about anything I need to fix whatever breaks. I might have $1000 total in all of it and I have saved way more than that just fixing broken stuff on my tractor that I would have had to trucked to a shop to get fixed. Of course I used to be a professional pipe welder in my youth and still can do a fair job when I get my tri-focal glasses lined up right so using the equipment correctly is not an issue. I have fixed bush hogs, 3 PH brackets, back hoe feet, broken drawbar connectors, built brackets for mounting tool boxes, patched up the rusted out deck on my old JD 332 lawn tractor, welded on chain hooks on all my FELs, just to name a few things. Way more that paid for itself and I still have all of the equipment which is worth more than I paid for it, so I think, yes it is worth it to have a welding machine. IF you dont know how to weld, take some lessons at a community college and buy you a Lincold AC/DC machine and some rods and start repairing your own stuff and building stuff. It is a lot of fun. IF your first repairs dont look to good or break again, grind off the weld and reweld them, eventually you will get good enough that everything holds together.
