Turns out the tip voltage was wired - to + even though the install said the only thing polarity sensative wasn't the raw tip voltage I did need to flip them.  Now an other problem and I rreally hope the last one is that on larger parts the torch shuts off during the cut.  The torch is off, the thc says there is no arc, yet mach3 shows the torch still on.  The movement does stop about 2 inches after the torch has shut off.  Anything larger then 11 inches does not get to be cut all the way.

ok Finaly got a hold of someone who knows the thc.  Torch rate was set too high.  Now it seems to be doing fine.
