    Miller 375 X-TREME Plasma Service Manual

    Anyone have a Service / Tech. Manual or Board Schematic For a Miller 375 X-TREME Plasma? Serial Number Range: LG130001P through LG190233P

    Need to Get the Value of R123 a Ceramic Power Resistor.

    Will be digging further but just removed the parts that had a visible catastrophic failure / damage

    Will Still need to find the failure that caused the Resistor to Go Nuclear!!

    You may want to call miller and ask for a Schematic for that board. The board part no. & Rev should be printed on the edge you will need it when you call them.

    Been a while but was waiting on the PTC R123 part Number (then got distracted) But, I did just today get a reply from Miller on the PTC it is a VISHAY (BC COMPONENTS) P/N: 2381-663-93025 VISHAY (BC COMPONENTS) P/N: PTCTL8NR100HBE so I will click go on the shopping cart Wednesday.

    Hope to free some time up mid next week and reassemble this been taking up way to much bench space.

    From the looks of the poor desoldering job above you prob damaged the internal layers of the board and may have to chase them out.

    What are all the parts #'s of all the transistors removed there will also be diodes that went if the IGBT's went.

    Left Hand side of the board you will have a part # and rev # call miller tech support be nice and they may e-mail you the schematic.
