As far the schematic, I am thinking of asking a buddy who guides me to attain this job with a lot of information on welding machines if he gives me permission to open his schematic design of this unit.

This buddy gave me OK to open his schematics on this project, will compile a bit and post here soon.
(Note he says the schematics are only for Hitachi's welder, version name 'ADGP' and some series after this. )

This schematic is just for Hitachi's TIG welder, ADGP series. Hope you can apply this for yours thanks.
