OK, so I began thinking about the electrical in this house and my needs, etc. I tend to be a heavy electricity user with welders and industrial sewing machines and other equipment and am wondering if I should make the move to 220. (Also, is it 110/220, or 120/240? I am getting conflicting answers on the net) I was wondering if anyone here would be able to give me some pros and cons of using 220 in my shop. Is it cheaper? More expensive? Reliable? My current welder and my heavy duty leather stitcher are both 110, but I want a bigger welder and my next couple of sewing machines have a 220 motor option. I am also plannig on getting more machines as time goes buy and I can afford them. Just wondering... is it worth it to have my shop wired for 220? I would not be doing this myself, I'd be hiring a licensed electrician.Thanks for any advice!
