Why does my MOT have a wire from the HV coil connected to the casing? Answered
I'm busy with making a spot welder from a MOT (microwave oven transformer), but I'm not really sure why and how to ground the MOT.
In the picture you can see that a wire from the high voltage coil is connected to the casing which I find to be Really odd.
That wire is not really a problem since I'm going to remove the secondary windings, but I'm just interested in an answer to that.
Another question is, is it necessary (for performance) to have the MOT grounded?
or is it Only for safety that the casing needs to be grounded?
(no matter what the answer is, I'm still going to ground it, so it's not necessary to have safety discussions here)
thanks in advance,
