Oh and I sure did learn a valueable lession out of all this. RESEARCH, believe none of what you hear and only half of what you see. I honestly should have gone into a welding shop in Aus and asked questions, (eg) can I buy a machine second hand off craig list and bring it back and expect to use it with out any problems? I have spoken to a guy funny enough from Everlast, and he said that the power in the states is different in as much as your 220 volt is two active 110 wires that's why your single phase can handel higher currents, well that's the way he explained it to me, he said it was devloped from the orignal DC system that's why it's unique. I sort of understand  rofl.

A standard panel in the US that has single phase coming in is 2 110 lines opposite in polarity. Every other breaker in the box is on an alternating leg. A 220 breaker is double wide grabing one of each pole. An appliance like a stove that is 220 can have an internal timer running off just one of the legs and neutral.

I doubt it has anything to do with DC. DC was Edison's thing and AC was Tesla's. They hated each other. AC won out because it transfer over a large distance with minimal loss in comparison to DC. They both had patents on things and would not license them to the other.

Are you sure about that?

They are 180 degrees out of phase. When one leg is positive, the other is negative and vice versa as they alternate back and forth.

When 240 power is required, a second sine wave is introduced exactly the opposite of this one so at the peak, there is 240 volts from peak to peak and zero at the crossing.  Good overview (new window).

I say plug it in and weld, if the neighbors pace maker skips a couple times then move it a bit further away.  PM me your address and I'll smuggle you a US plug in for it and you wont have to swap the cord.  No charge.  ;D

I cannot really verify this but from what I'm seeing researching this,Aussie power is unlike ours. We have a load wire(black) supplying 110V ,a common(white) return to source,and a ground. Aussie uses one leg of 220V,one leg return to source and a ground. Soooo....... don't do what Carl(and myself previously) suggested. A few readings with the voltmeter should verify this.

So we've got a push+tug and a tug+push.  They've got a PUSH and a TUG.  I'm not seeing a difference in the end result.  Three wires still makes 220 volts with a ground.

the diff is that we have 2 legs of 110 each for 220 where they have 1 leg of 220. BIG diff to the machine IF I'm understanding their AC supply system correctly.

Yeah but the two 110 are still combined in the machines power supply.  But I will say if the machine can be made to conform for a few $$$ then that would be faaaarrrrr better than finding that neighbor dead cause her pace maker skipped a few beats.   nono nono  Seems the info is like finding out if the gov know of any alliens. LMAO LMAO
