Got a new miller plasma but I can't get it to work

[drift_g35]

I just traded a forum member here for a NIB Spectrum 2050. I would contact him but he left for training in Cali and I don't think he will be reachable for about a month.

I am having problems getting it to do anything. I can get the Power and Ready lights to light up, and can force the error lights with pressure and cup. But when I try to do anything else it just doesnt arc. Its odd because there is no hum, fan or anything else that would show the machine was on. Any ideas? I will admin that I am a total noob to this so i'm hoping i'm just doing something stupid. Here are some pictures.

Also I have turned the psi down to 70 and checked the consumables.

Could be a stupid question on my part, but what type of material are you attempting to cut?

[drift_g35]

Just simple mild steel. It's a tiny piece of angle iron. Even sanded the rust off to make a good ground.

Hmm. Sorry, I have no idea. I've used a couple of different plasma cutters and don't remember there being anything tricky or unusual.

There red isn't some sort of resettable circuit breaker on it somewhere, is there? Maybe it tripped.

Continuity test your leads to start

Check to see how the line disconnect device is wired. It can be wired for either single or three phase power. If it is wired for three phase and you only have single phase running to it, all of your lights will turn on but it will not operate. And don't take the fan not running as any sign, it only turns on on this machine when it is hot enough to need it.

What is your power source?

Would this help? Only issues i've had were due to bad ground, doesn't sound like that's your problem. There's always miller tech support

Difficulty establishing pilot arc may indicate consumables need to be cleaned or replaced.

Power must be reset whenever the cup shutdown system is activated.

So I think I have it wired up wrong. Here I think I need to move the white wire (Grey in picture) to the spot the red wire is in and tape off the red. Do I have my box set up right? This is a horrible drawing and I can take pictures when I get home.
