DIY microwave spotter

There is no need to throw away your old or used microwave oven. Kitchen appliance components can be used to make new electronic devices. One of these is a spotter - a faithful assistant to every motorist.

Application

The spotter is used by car enthusiasts to straighten dents on the car body. It will help correct unevenness and damage, correct the consequences of minor accidents or collisions. If used correctly, it is not necessary to go to a specialized salon. You can carry out repairs at home.

DIY assembly

The device is based on a transformer. In a microwave oven, it performs the function of processing and redistributing the incoming current. In the spotter it is used for a similar job.

The windings (primary and secondary) fixed in the core are responsible for the correct operation of the transformer. To manufacture a welding machine, the windings are dismantled and new ones are attached in their place.

The primary requires 200 turns, the wire is no more than 2.5 square meters. mm section. To make the secondary one, a wire of 55 square meters is used. mm section, no more than 7 turns. Replacing the windings is designed to generate the current required for high-quality operation.

Manufacturing of electrodes

After making the base of the device, you can begin making the electrodes. To do this, you can use small round copper rods. Bronze or copper tubes are also suitable. They are useful in that they are easy to connect to the cable responsible for carrying the current.

An incision is made on the wires on one of the sides (working). It is necessary for attaching the washer. When using tubes, one of its ends is flattened with a hammer, and only then the necessary cuts are made.

Providing convenience

For additional convenience and safety, the finished product must be provided with a housing. You can use the housing from an old microwave oven. It is distinguished by its reliability and structural structure. This method will help protect the device from contamination and mechanical damage. Thanks to this, the service life of the spotter will significantly increase.

For more convenient movement, the lower part of the case can be equipped with small wheels. Before placing the block in the housing, it is advisable to make a base from a dielectric sheet. It will provide a tight fit and make the device easier to carry.

The gun is used for attaching electrodes. For its manufacture, it is recommended to use materials such as getinax or textolite. They provide ease of use and safety during the work process. A pistol-shaped shape (2 pieces) is cut out of the materials.

During manufacturing, you should pay special attention to how the gun will be positioned in your hand. Don’t forget about the special recess in one of the blanks. It contains the power button and electrode mount.

Features of a homemade device

A homemade spotter has a number of advantages:

• using components of an old kitchen appliance;
• minimal costs of money and time;
• skills in constructing new devices;
• saving money and personal time, since there is no need to contact a specialized center.

Important: the assembly of a homemade device should be approached with special care, observing safety regulations.

Conclusion

A spotter is an indispensable device when repairing a car. Simple skills and a competent approach will help you make a spotter from an old microwave yourself. It will help in repairing minor body damage at home.
