Step 2: Putting it together!

Picture of Putting it together!
 Yay the fun part. now I shall continue to give you a brief (or detailed depending on how energetic im feeling as its currently 2am!) outline of the set-up along with a labelled picture and a schematic.
For starters or as...

Step 1) get your base whatever its made of and place your MOT's on it two to three if you have three put two side by side not touching, and one in front of them, if you have two just put them together side by side not touching each other. then screw them onto the board to hold them in place.
Step 2) Wire your switch, circuit breaker, and the plug that's going into mains supply together. The "hot" or "live" wire of mains shall be connected in series with your circuit breaker, then to your switch, then to you PFC capacitors but ill cover the PFC later. Then the neutral line goes straight to the PFC, and last but not least the Ground or earth line connects directly to your MOT's Ground connection and if you have anything made of metal Eg. your switch box, GROUND IT!

Step 3) Power factor correction. your power factor correction capacitors will be in parallel with your Live and neutral lines, neutral down one side and live down the other, then to your MOT's For my PFC instead of the motor start capacitor im using 3 MOC's in parallel with mains connected to my MOT's. 

Step 4) Connecting the MOT's. First off to power up a MOT you need to identify the primary winding. the primary will most likely be on the bottom close to a base plate. and have two spade lug connections next to each other, with thicker wire and less of it. now to connecting it. now if its just one MOT you can connect the power to it on the primary either way. and it will work fine. But with two MOT's you will have the input in parallel and in phase, so live will be connected to the same side on both MOT's so they both phase in which will allow arcs to be drawn rather then short bursts of flame.

Step 5) Wiring the Output. First you need to identify the secondary windings, the secondary is obviously the one that isn't your primary as there's only two windings. its got thinner wire and lots of it.  There is two parts to it. the High voltage out which is a single spade lug connection on one side or the other. and then ground which is grounded to the Metal core of the transformer itself. so if you were to power up a MOT and connected the high voltage out connection to the transformer it would arc. Okay now connect one of the spade lugs from one MOT and Connect it to the base of the next MOT, This puts them in series so the high voltage out of one will arc to the transformer core of the other.

Step 6) Ballasting. Get your last or third MOT and connect a single wire to short out the primary winding. then Get the Ground end of your two MOT's and connect that to the secondary out lead of your ballast MOT.  and connect a scrap piece of wire off the Base of your ballast MOT as that is where you will draw arcs from.

Step 7) Resonant Capacitors. Now you will Need your MOC's get four of them and series two parallel sets of 2. and attach one end to your High voltage out of your two MOT's then attach a large length of wire to the other end of your MOC's and attach that to your Insulating pipe for your chicken stick. you will use this to draw your arcs.

Step 8) Now it should be all wired up. Plug it in, turn on all your switches and Draw some hefty arcs! WEAR EYE PROTECTION! ITS WORSE FOR YOUR EYES THEN WATCHING SOMEONE WELD!

theres a problem there is no two live wires used , to my knowledge you use a ground and a live phase for 120v

What is the Purpose of the PFC capacitor? whould it still work if i didn't use one?

Im not sure about step 4, connect the "ground end" of the two MOTs? Do you mean to say that HV out of one goes to base, then either base or HV out of 2nd hooks up to the HV out of the ballast, and you draw arcs from the wire connected to the base of the ballast? Is that correct?
I thought you weren't supposed to continuously run start capacitors, I have one that I found in the junkyard and have nothing to do with it so I'll use it for this.

Nah, they aren't made for pulse discharge, but they handle the mains continuous cycle fairly well.
is the PFC capacitor also a MOC?

3 MOCs in parallel make for good PFC
