Welder Schematics

[cruizer]

Really unsure why you want to go through the shematics which you would not find anyways due to the many updates and movement of parts different serial#'s get, never the less, a better question would have been. "What causes a HLP 7".

Hlp 7 points to the right side (output) board, likely a capacitor drain resistor is pooched. I get them from Newark.com

Wishing I could acquire more detailed schematics when making component-level repairs. Currently working on an Invision 459P with a #7 fault. The PCB's in the schematic are only block-diagram. I can remove the board and "draw it out" visually, but a print from Miller would be so much easier.
Thanks for your time,
