I don't know what you plan to do with this welder but a 1/8" 7018, or 5/32 6011 rod will probably run comfortably at 110 amps or less. Your arc voltage will probably vary between 20 and 30 volts. 30 x 110 = 3300 watts when welding. You will You guys will have to do the math to account for losses while you backtrack to the 240v line. Your biggest amp draw will be when your rod sticks to the work.
