Im using this microwave oven transformer in a spot welder, it has a sensor in series with the primary winding glued to the core. I thought it would be a thermistor with increasing resistance at higher temps to protect the transformer, but when i teated its reaistance, its stayed at 30-40 ohms when i warmed it up with a soldering iron (upto 150c).
Faulty sensor? Didnt want to overheat/melt the plastic…
Sensor is in the photo and im pointing to where its attached, think they all have on, have seen a few like this…
Thanks!
