Please help.. in my gerage all I have are 3 or 4 outlets all normal 120 household outlets, I'm going to start welding at my house to keep up with work and my welder needs a 240 outlet. I have a late 80's early 90's fuse box and not 1 240 outlet in the entire house, how can I myself install a 240 volt outlet?
Thank you for your time..

Depends on what you know about electricity. Do you have at least a 100 amp 240 volt service panel. If so first you would have to have an open space for a 240 breaker, Next you will need to run a wire to your welder plug, not knowing what size welder you have I would recommend a #4, 2 wire with ground running to a 60 amp disconnect. Then you will need a plug in box to match your pig tail or what every comes out of the welder.
