I think your camera would be safe for the same reasons that your SD cards (or whatever) and the non-volatile memory inside the camera would be safe. However, if there was anything causing arcing (e.g. mechanical switching of high voltages), that might be a different story.

In the case of arc welding, whether it could cause damage to the electrics or not I couldn't say for sure, but I wouldn't want to get too close just in case, and I can tell you for a fact that it can damage the sensor if you are taking pictures of the welder's arc or making a video recording of it.

Thanks all, a miracle happened. Found a knowledgeable and honest computer repair man. Simple fix, my previous repair shop installed the DIMMS in the wrong sockets and failed to notice their error on 3 subsequent visits.

If anyone in the Green Valley AZ area needs repair work done PM me and I'll give you the info.

I have always been an advocate for Referbs. I have purchased a number of bodies and lenses from Nikon. Some directly from Nikon, some from Adorama, and other companies that sold Nikon referbs. I always had perfect performance from them and suggested referbs could potentially be better than new. I felt new might be perfect or might be just barely within the tolerances allowable. I felt referbs would have been gone over by a technician which would not happen if one came straight off the line. So here is what happened: I bought a z7ii and some lenses and wanted to use only mirrorless for a while before getting farther into this kind of camera. I felt if this was going to be an ongoing test there should be a backup camera. Nikon ran a sale and the z5 was less than 900.00. I received one and to my surprise, it was more like new than referbed. Not the slightest mark and when I took shots to feed to the website that reads shutter counts, it must have been zero since the few shots I took showed as only 6 clicks. I felt great about getting what appeared to be a new camera for a much-reduced price! After shooting a couple of times with no problems, suddenly a problem did show up. The camera wouldn't clear the buffer in any reasonable time. I would take a photo and the little green light on the back of the camera (that shows it is processing) would stay on for 15 or 20 seconds. Sometimes the shot would come up on the rear screen after that time, sometimes it would not. When I would hit the review button sometimes the shot would come up, and sometimes it would go into the processing mode again with the green light coming on for 15 to 20 seconds. Since it was under their 90-day warranty I called and asked to send it in for repair. After listening to the description of the problem I was told to send the camera back for a refund. I protested stating I had purchased it on their sale and if I sent it back for a refund, I would have to pay more to replace it. I also told the Nikon person I shouldn't have to pay to return their mistake. He was very nice and understanding and sent me a pickup UPS label so I did not have to pay for the return. He also gave me a code to get 20% off their website so the new camera would actually have been 20 or 30 dollars less than the original one with no charge for shipping. He also said the code could be used for a lens if I preferred. When I went to their website to repurchase the z5, I noticed a z6ii had become available so I used the code to buy that instead. I believe if the new camera is as good as I've been used to in the past with referbs, this will work out for the better. The one thing I missed on the z5 was the little window on top which is easy to check a few setting on the camera.
