Put a 50 amp circuit in with wire sized to code ( I think it is 8ga to the receptacle) and the get a extension cord made out of 8/3 SOOW cord. I bought a 50' extension cord with 6-50 ends, the same as standard 230v ends that miller welders come with, for $130 to my door. Some of my machines have long cords and some do not, the extension works great. I use it all,most every day.

Get 2 bottles of gas like mmw said. Tig is fun. I learned to gas weld first and it made learning a lot easier. Enjoy your new machine!
