    Default Spectrum 300 Cutmate help

    Hello,

    I bought a used plasma cutter. It seems it has two capacitors that are blown. They are the size of a "D" battery and say Phillips 1000uf and UR=300V. I am guessing this is all the information that I need to buy two replacements and solder them to the main board. I have them off of the board.

    The capacitors also say 157 93075, M HP 9820:, and 25/085/56.

    I was also wondering if anyone here had a schematic to tell me which terminal went to the outside of the board (the top) so I could solder the proper ones back in correctly.

    Thanks for any help here.

    Can't help you with the first part of the question but you can download a manual here: http://www.millerwelds.com/service/ownersmanuals.php
    It should have the schematics you need.

    Default progress

    I found the capacitors. $20 to my door. Lets hope they are all that is bad.

    I am curious if anyone knows of a replacement program since Miller has admitted that these boards were made poorly? I know there is a new part number, but will Miller lower the price for a trade in with the old part?

    Thanks in advance.
