    Craftsman 220 AC Stick Welder
    Hello Folks, When I purchased this welder I was on my way to installing 220 in the garage. However, those plans fell through and now I need to know how to use the 110 service to Stack the voltages, and provide the same 220 volts to run the welder. I realize the feeds would have to be off different breaker outlets to give the needed amperage. Please Advise, ALL Ideas and Suggestions are Welcome. Thanks, Jim.

    I have NO Idea what this means! To be honest this statement kind of scares me a bit.

    "220" is only half the equation. You need the amperage, and in this case 50 is your amperage.

    There is NO WAY to "rig" this to make it work. You MUST have a 240v-50A circuit for this.
    Even thought welders follow different codes than most other wiring circuits, you should use #6cu of running NM cable, or #8CU if running wires in conduit.

    Better yet, call in an electrician to give you an estimate.

    May be you would need a step up transformer to get 220 V out of 110... but that is not all.. you would need to be sure that your original 110V could provide the necessay amperage to your device before and after being stepped up.

I found an old lincoln welder that I can't identify. I guess it looks like a water tank about 4 feet tall and 3 feet wide with a crank on the side. Ring any bells
