Along those same lines, replacement water heater elements could be used in those higher voltage environs. The mica sheets wound with the flat nichrome from old bread toasters might also be a suitable source. Shield those from swarf obviously. Ditto for old electric clothes dryers. > On Thu, Apr 17, 2014 at 9:56 AM, Viesturs Lؤپcis <viesturs.la...@gmail.com>wrote: > > Hello! > > > > I have three chinese servo drives in the waterjet machine and they are > > constantly faulting with "overvoltage" error.
