Microwave transformer schematic. One is black and the other is red. Conduct a microwave energy test after performing any test or repairs to the microwave. An alternative way of determining if the problem is in the control circuits triac relay wiring or microwave generator hv transformer hv capacitor hv diode magnetron wiring etc is to connect the hv transformer primary directly to a line cord and plug. I screwed up in checking power to the transformer and didnt mark which wire went to which input terminal on the transformer.
The few turns of very thick wire wound on top of the secondary supply about 3v at a few a to the magnetron filament. Microwave transformers use one of the hv leads connected to the transformer case which is earth ground in a microwave. Primary winding lower thick wire 230v secondary winding upper thin wire 2kv. Any help in determining the.
Check that all wire leads are in the correct position before operating the microwave oven. One winding provides 31 to 32 volts while the high voltage winding provides between 1800 2800 volts average 2200 volts. At points 1 and 2 electricity is being fed into low voltage transformer which is located at the other side of the board. Transformer from microwave oven.
In this project youll learn step by step how to modify a microwave oven transformer into a high current device that can pump out 800 amps of electrical current which is enough amperage to melt metal. As i plugged in the power cord to the main the circuit blown again at the back of low voltage transformer pcb. This inverter in this video is rated at 75 watts using the current transistor. Wire microwave transformer for woodburning schematic in this video i show you how to reuse an old making a lichtenberg wood burning machine from burn fractal patterns into plywood diy art make and the figure with electricity markism net electrified trees 4k pictures kit tweaking my 10kv power supply products of mikes mind welder man plan robot device youtube turn oven high amperage metal.
Conduct all operation tests with 1 liter of water in the oven. The low voltage output is used to light the filament in the microwave generating vacuum tube called a magnetron. I soldered some wires for reconnecting the lost circuit and placed the pcb to check how it performs. Grasp wire connectors when removing the wire.
