Hi Mike. I just downloaded the new update 20.5 fire control and now I’m getting Arc Voltage loss code every time I run the program… I have checked everything for troubleshooting with no results… Please help
Hi Todd-
The Arc Voltage Lost error has nothing to do with FC20.5
What voltages are you seeing when you are trying to run?
My voltage is between 130-148… After dinner I went back out and everything ran fine. The only thing I did different was to hold my laptop… Before my laptop was on top of a bucket full of scape metal… I don’t know it that caused the issue with interference…
In this case, I would suggest that you make sure you don’t hold it on bare legs. This sounds very much like ground loops that could be harmful…
Hypertherm 65sync and Panasonic Toughbook (auctioned off local PD laptop) Was working great one job then next job statred getting 27-40 volts instead of the normal 130ish. Of course torch height was all over the place. Resting voltage would bounce from 0 to 6 volts without touching anything. Tried laptop unplugged no change. Place laptop on a towel on laptop stand. That fixed the problem. The toughbooks have a steel and aluminum frame and it was grounding out on stand.
