What can be done from a microwave transformer

There is a microwave oven in almost every kitchen today. Manufacturers are improving the device, equipping them with additional functions, giving them all new features.
An older oven model is sometimes simply thrown away. But do not do it! After all, its components will still serve in skilled hands.

Microwave Part Application Ideas

The copper wire on the coil, decorated with several rows of windings and metal plates, often remains operational even after the microwave has failed. Therefore, it is too early to get rid of it.

We offer options for using a microwave transformer.

How to make a former transformer a power supply

• Remove the part from the microwave.
• Remove metal plates. To do this, you need tools (screwdriver, chisel).

Tip. If you apply a grinder, the work will be easier to do. In this case, care must be taken not to damage the windings.

• Carefully remove 3 windings.
• For the power supply you will need one of the large ones, designed for 220 V. It is thicker than the other, but less wire is used.
• Wind the desired winding onto the reel.
• Place the coil on the core shaped like the letter S.
• Perform calculations for the second layer of the winding. This is done experimentally. Start with 10 turns on the core. Then voltage is applied through both windings and data is measured on one that consists of 10 turns. With an indicator of 10, you can continue to work. The final number of turns depends on how much power is needed.
• Fix the core.

The base of the power supply is ready. For its final production, you will need to arrange it in a special case and equip it with a diode bridge and a capacitor.

It is hardly possible to call this method of work simple. However, as a result of the laborious process, you will get a powerful power supply, the acquisition of which would require significant funds.

Welding machine

Even small repairs in the house or in the garden often require welding.

If you have an unnecessary microwave, you can make yourself a convenient and reliable device for spot welding.

• The transformer is taken out of the microwave.
• Remove the existing secondary winding.
• Make a new winding using a wire whose diameter is at least 10 mm.

Important. If you do not have a thick wire, you can replace it with several thinner conductors. The main thing is that the sum of their diameters is 10 mm or more.

Tips for using a transformer

1. When working with a thick wire, you can remove its thick insulating layer and replace it with electrical tape, one side of which has a fabric base. In this case, the winding will be made easier.
2. If you are working on a welding machine, keep in mind that it is suitable for joining thin sheets of metal.
3. To weld thick plates and increase power, you will need a second transformer.
