[Mike Worth] desired the choice to run his Microwave oven Transformer welding rig at less that full power. After being influenced by a few of the other MOT hacks we’ve featured he figured there should be a great deal of methods to do this. however his searches on the topic didn’t turn up anything. So he just developed as well as developed his own adjustable present limiter for the welder.
At the beginning of his review he details what we would phone call a bootstrap procedure for the welder. go back as well as inspect out his original develop post to see that he had been holding the framework for the cores together utilizing clamps. To make the configuration much more robust he needed to weld them, however this is the only welder he has gain access to to. So he taped some wood protecting over the coils as well as terminated it up.
The present limiter itself is developed from a third MOT. modification is made to the cores by altering out the E as well as I shaped pieces. This enables for present limiting without altering the windings. [Mike] holds everything in location with a couple of bicycle wheel quick link skewers.
It just goes to show that you ought to never get rid of a microwave without pulling the transformer. even if you don’t requirement a welder wouldn’t you like a high-voltage bug zapper?
