    Need schematic for Eltee Pulsitron EDM

    Hi, I've been googling around and ended up here, not sure if anyone can help.

    I have an old Eltee Pulsitron conventional EDM that blew up last week. A friend is good with electronics and has fixed several things but now we need a schematic for the gap condition board. I have the manuals with the general schematics, but this is not included.

    Can anyone help? TIA!

    I used to work for Eltee Pulsitron

    Hi,

    Maybe I can help you out. I used to work for Eltee Pulsitron from 1981 to 1986. I was the head of the test floor and Sr. Electronic Tech there for 5 years. At the time that LT closed there doors, I went out on my own and started repairing these machines here & there. I haven't done any in recent years but I still have some parts and components. I remember alot of the machine & circuits. I don't have any schematics but I can make one from a board. Since you have the schematics, this may help me too. Maybe we can do some business. Where is the machine located? Please reply to [email protected].

    Re: Need schematic for Eltee Pulsitron EDM

    I can't believe I'm back here after 14 years.

    I recently retired and am selling everything, but my Eltee quit working a while back. I would imagine that right now it is only worth scrap. My buddy has spent quite a bit of time trying to track the problem down. What happens is that when I press the "Cycle start" button, it clicks and the light goes on -- but the ram won't move.

    What we know:

    - The voltmeter should go up to around 100 when the button is pushed, but it doesn't move off zero.
    - There is no voltage at the ram.
    - Jogging works fine.
    - There is no continuity between the ram and some component (?) inside the cabinet, and there should be.
    - He has narrowed the problem down to either the pulse timers or the gap control board.
    - I have the general schematics that came with the machine when it was new, but we need the schematic for that particular board.

    As it is, I'm not sure I could give it away, considering the cost to have it moved. If we can't get it fixed I will probably have to pay somebody to haul it out of here and scrap it.

    Nah, it's still dead in the water. Anybody here interested in it, plus a WORKING Hansvedt Bench SMB150 EDM? Will let them go very cheap.
