    Default Spectrum 2050 issue

    I have a Spectrum 2050 Plasma that I've not used in a year or so. I powered it up yesterday, everything appeared to be fine, until I pulled the trigger and not only did I get no spark, but noticed a small flash along the right side of the machine. I opened the machine to find the large surge resistor blown, and two other resistors were brown from heat, but not blown.

    Today I replaced the large blown resistor, but same symptoms. The resistor started smoking immediately, but i stopped before it blew.

    The manual from the Miller site for my unit, based on the serial number does not contain a wiring diagram. I did find manual for a newer 2050 that does have the diagram. So far, the relevant pieces seem quite similar. See attached pic identifying the issue....

    Thoughts?

    Thanks,

    -Travis

    Cause your diode bank is likely blown and you have a failed IGBT. Your going to be running around with this unit due to several redundancys. Best stop while your ahead, and replace the unit.

    In other words, its going to get real $$$ costly, and your not going to get anywhere......
