O'ya, just because that outlet is rated 110 volts doesn't mean that it is going to be able to handle that welder. I just fried a circuit for this very reason, when I absolutely knew better. Also if you are renting an older home the wiring sytem in itself may not be up to the task. I think that you will find that nearly all landlords are not going to authorize you to put a 220 volt in, especially when they find out what you intend on doing with it. The threat of fire, damage to their house, visions of clunkers in the driveway, etc.
