    Default Spectrum 375 x-treme power light blinking

    Earlier in the year, I bought my spectrum 375 x-treme plasma cutter. I used it twice. Today, It will not operate. Machine turns on, when I pull the trigger the power light starts to blink.
    Things I've checked and verified:
    Voltage is 240v also tried on the 110v plug
    pressure is within range and have adjusted it from 90-130 psi.
    tips, etc are brand new miller
    moisture trap inside machine is fine

    I have looked all of the older posts on this machine with similar problems and have come up with nothing. Any help would be greatly appreciated!

    Double check that you have 240 volts getting to the unit.
    Check trouble shooting grid in your owners manual.
    If under warranty take to warranty shop for repair.

    There are 3 of the x-treme 375 units, maybe serial# would be handy....
