I agree that, done right, there's nothing wrong with shortening. That said, it does need to be done right. It shouldn't be your first welding project, and you shouldn't try to do it with a 110V MIG. It's a life safety issue, so it needs to be done by a competent welder with the right equipment.

A good 110v mig can do 1/4 just has to be done properly. If that is all you have then just plate and bolt the joints when you are done.
