/diy/ - Do It Yourself

I noticed a curious side-effect from my homemade MOT welder (from a 1.45KW microwave). Normally, when I test it I make sure to unplug everything in the room, all PCs, Stereo, etc. Now, my house is wired so that in one room there are 3 breakers. 1 for the lighting and 2 for the wall outlets. The outlet are arranged to one break leap-frogs the other one. Like A, B, A, B, A, B around the room.

This is for when a breaker is tripped I can simply unplug from that outlet and plug it into a still working outlet. It's a great system. I keep all my PCs on break A and tools and testing on breaker B.

Now, everything has been smooth sailing because I unplug every thing for the MOT testing. HOWEVER, one single time, I left one PC hooked up and on. When I fired up the MOT, it knocked out the PC. Luckily, it didn't harm it that much, it only stopped it from working. However, it one of the 2 video cards is now non-functional.

The distance from the PC to the MOT was about 5 feet. Now, is this EMP damage (the PC doesn't have a cover) or some sort of line interference even though they are both on different circuit breakers?
