How to build a spotter with his own hands?

Spotter is a device that is at the time of passage of the current allocates a large amount of heat directly to the contact zone of welded parts.Particularly this device is indispensable in those situations where the surfaces with dents can not get close to the other side.For example, to fix the rear fenders, doors and thresholds.The force in this case will be applied only to the outer surface side.And it is quite natural that such a device would dream to have in the arsenal of many car owners.However, the price of new equipment can now be up to several hundred euros.For this reason, some motorists are hesitant to do spotter hands.

list of necessary tools

Before proceeding directly to the build process, you should make sure that all the necessary work tools and materials.First, be sure to need the welding transformer and electronic relays.The latter should be set at the thyristor V9.Second advance need to take care of a small auxiliary transformer, which will subsequently be responsible for the power supply to the control system.Third, be sure to need the power unit and the welding gun.

It is from these two parts, in fact, all homemade and consist welders.Fourth, a small amount required flexible cable and the housing.With the first will connect the details that make up a homemade spotter, and the second will be needed for the power block.Finally, fifth, necessarily need to build a circuit diagram of this type of equipment.

How to make a spotter with his own hands?

To collect directly the device itself, as mentioned earlier, will require only two elements - the power unit and the welding gun.This applies to the last part of the traditional semi-automatic, but it will need to build in the so-called axis of brass with thread type M10.It is because it is attached to the device for the straightening machine.And only after that it will be possible to strengthen welding cable.Among other things, it should be emphasized that the other end of the wire should be placed power connector required for fastening.Moreover, making spotter own hands, it is important not to forget to attach the thrust washer pair of pins, and the back side to fix the rubber pad.

Benefits homemade spotter

The main advantage of a home-made device, it is significantly different from any other type of welding is that it will not have welding gun.It takes only a fastening element, for which you can choose anything you like - from the most common nuts to the studs.In addition, one of the main advantages that spotter, harvested their own hands, experts rightly called that the surface temperature with a dent in the area of ​​direct contact will increase to a point that only a couple of degrees will not reach the melting point.Subsequently, it will enable very firmly secure fastener.To work with such a tool - a real pleasure!
