To the OP, Well Gene, looks about like I said earlier, the 120 volt works, but not really to your satisfaction. Cant run the sizes of rods you would like at the heat settings you would need without breaker tripping. You really need at least a 240 volt (or what ever it runs in your area) at least 30 amp circuit and breaker, and at a minimum #10 wire, BUT I would go bigger. And here is why, what if some day you want a larger welder? I put in a 50 amp circuit (kinda standard for homeowner welding circuits ) and wire and breaker sized to match. While I have never gotten a larger welder, I can if I want to.
