I have used some of these small welders, but they were 120v with 20amp cord caps. You might want to invest in a heavy duty cord even if you have to make it your self. If it draws more than 20 amps it must have a 30 or 50 amp cord and cap on it. We allways used heavy duty cords to reduce voltage drop.
