The best option you have is to get a qualified electrician to install a dedicated 220 circuit for your workshop. Do it right! Every year hundreds of homes go up in smoke caused by faulty electrical wiring. This is not to say you are not able to do it yourself. Depending on the location of your breaker panel and of there is room for an additional 220 breaker. It may turn out to be an easy job. Ask around you may be able to get qualified help for little or no money, if that is a concern.
