I think you've got it wrong, two 110V lines that's 0 degrees apart would give 0 Volt.
They must be 180 degrees apart, that would double the voltage to 220V.
And that would actually make it 2-phase.

Yes, I don't know why I wrote that. The two lines have opposite polarity, which makes them 180 apart.

It may just be semantics, but I don't think this meets the definition of 2-phase, because it is all part of just one signal. A historical 2-phase system has 4 wires and they are 90 degrees apart. For residential 220V, the power is delivered on just two wires (neutral and gnd carry no current), making it single-phase (like an oven or heater). I suppose a motor could be wound with dual 110V windings, but I don't think anybody ever does this.

The power from the power company is 3-phase, but each residential pole is tapping just one of those phases.

Sorry for getting off-topic

The problem with flux core is it sucks! (unless you are welding in the wind) MIG welding is so much more clean and easier than flux core, the welds look better, and no cleanup after. I say it's worth it for the gas setup.

Well we all dont have $200 laying around for the gas setup lol. If you weld alot get gas, if its something you do occasionaly I say go flux and deal with the mess. A wire brush and grinder clean it up quite nice

I got my 80 lb bottle for $100 and I 'own' it. No rental ever. Costs me about $40 for a fill. I get about 5-6 hours continous welding out of a bottle.

Flux cores best use is welding stuff at the upper limits of thickness for your machine. If I'm welding 1/4" steel with my little 135 Millermatic I will use the flux core as it digs harder. For bodywork stuff, you cannot beat 75/25 gas and small wire.

Okay everyone who is confused about the phases of electricity I will try to answer although it has been along time since I've delt with this. When phase is referenced it is referring to the rise and fall of the voltage from 0 to the maximum(220) then from the max to 0, and then rising again but a negative voltage. If I remember correctly its a sine wave.


what most of you are referring to is technically called split phase where you do not need a neutral. Ie you get your 220v from both hots because the hots are 180 out from each other. This is caused by your center tap transformer on your pole.

hope that clears everything up.
