How to collect a spotter with your own hands?

Spotter is a device thatthe current passing moment produces a large amount of heat directly in the contact area of ​​the parts to be welded. This device is especially indispensable in those situations when it is impossible to get to the surfaces with dents from the back side. For example, to correct the rear wings, doors and thresholds. The force in this case will be applied exclusively to the outside of the surface. And it is quite natural that many car owners would dream of having such an instrument in their arsenal. However, the price of new equipment can now reach several hundred euros. For this reason, some motorists decide to make a spotter with their own hands.

List of necessary tools

Before proceeding directly to the processassembly, you should make sure that you have all the tools and materials you need to work. Firstly, you will definitely need a welding transformer and an electronic relay. The latter must be installed on the thyristor V9. Secondly, in advance it will be necessary to take care of the presence of a small auxiliary transformer, which will subsequently be responsible for powering the control network. Thirdly, you will definitely need a power unit and a welding gun.

It is from these two parts, strictly speaking,consist of all homemade welding machines. Fourth, a small amount will require a flexible cable and casing. With the help of the first, the parts making up the homemade spotter will be connected, and the second one will be necessary for the power unit. And finally, fifthly, you will definitely need an electrical circuit for assembling this type of equipment.

How to make a spotter with your own hands?

In order to collect directlyThe device, as already mentioned earlier, will require only two elements - a power unit and a welding gun. In this case, for the latter, a part from the traditional semi-automatic is used, but it will be necessary to mount the so-called brass axis with M10 thread. It is thanks to her that the device will be connected to the straightening machine. And only after that it will be possible to attach the welding cable. Among other things, it should be emphasized that at the other end of this wire there will be a power connector required for the attachment. In addition, making a spotter with your own hands, it is extremely important not to forget to attach a pair of studs to the thrust washer, and fix the rubber gasket on the reverse side.

Advantages of a homemade spotter

The main advantage of the homemade device,which essentially distinguishes it from any other type of welding, is that it will not have welding clamps. It will take only a fastening element, which you can choose from anything you like - from the most ordinary nut to the stud. In addition, one of the main advantages that the spotter possesses, assembled by its own hands, experts rightfully call that the temperature of the surface with a dent in the area of ​​direct contact will rise to a mark that does not reach a melting point by just a couple of degrees. Subsequently, this will make it possible to fasten the fastener very firmly. To work with such a tool is a pleasure!
