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!
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].
Can you please share available information for the subject matter I have recently bought 2 nos of second hand machine without documentation.Quote:

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.
Anything here? Do I have a pile of scrap?
Did you ever get this sorted out? I have the same machine.
