What it is?
The Spotter is a unique tool that is used for spot welding and produces excellent results. Basically, it is used in the repair of transport equipment, and in some cases in construction. It allows you to restore the product quickly and efficiently.
The principle of its operation is the same as that of other welding machines: the device heats up and emits a large amount of heat at the place (point) where the materials to be welded are in contact. An electric current is used to release the required amount of energy.
The tool makes it possible to repair any body elements, however, it shows great efficiency only when working with dimensional parts, where access to the inside is impossible.
The main advantage of the spotter is that it is able to straighten material without dismantling.
For this, a special pulling technique is used: fasteners are installed on the problem part, which allows you to pull out the dent. Any adult can carry out such an operation, since the average thickness of the body panels is only 1.5 mm.
The main difference and technical parameters
Most of the models are presented in the same form:
- The device with which the contact welding process takes place;
- Grounding cable;
- The wire to which the current is supplied is attached to the end of the welding gun - the main element.
For greater efficiency, the gun can be equipped with various nozzles, so the user can make any repairs without any problems.
There are controls on the front panel that make it possible to adjust the instrument in terms of power and current, which is very useful for working with some details. Modern models have an informative screen, which makes it possible to see the current technical parameters, which allows you to keep the process under control.
Types of spotters
There are 4 main representatives in stores that will allow you to perform work of any complexity:
- Inverter. Such a device is equipped with an excellent converter, which makes it possible for correct operation and does not depend on the current voltage. This allows you to carry out operations of any complexity during power surges, and also expands the list of tasks. Most often, such devices are small in size and allow repairs to be carried out quickly and accurately, since the current strength is stable.
- Transformer. This option requires constant recharge, therefore it is connected to the AC mains. The main advantage of such models is their low cost compared to inverter models. Their functionality is enough to perform simple repairs. Three-phase options are in great demand, which have increased power, which means they expand the list of work carried out.The only drawback of this representative is that it cannot be used when repairing galvanized elements.
- Spotter for working with steel. A popular model that makes it possible to carry out repairs with steel body parts (elements).
- Tool for working with aluminum. Since this metal is completely different from the previous one in its technical characteristics, then the equipment for work must be appropriate. Because this is the only way to perform the operation quickly and efficiently.
The main features of the repair
Knowing the key features is one thing, but the main thing is to be able to work correctly with such a tool, and most of the attention is paid to this.
The first thing an employee needs to do is clear the problem area. Install the mass and fix it with a special clamp, you can also weld it using a contact.
For work, elements are selected in accordance with the classification of damage, depth and size of the dent.
Spotter can work with the following elements:
- Wire that runs in the form of a wave;
- Small hooks;
It is also necessary to take into account the area of the dent, because the technology of work depends on it.
Small dents. This is the most common problem that can be dealt with without much difficulty. For elimination, the reverse hammer method is used.
This option will easily cope with most of the damage that is found everywhere. The work takes place as follows: the end of the device is welded to the problem area, after which it is straightened with weak blows of the internal element.
In order for the work to be done perfectly, such manipulations must be carried out around the entire perimeter, where there is a dent. When welding, it is important to maintain a distance between points up to 8 mm, then the result will be visible immediately.
It should be understood that small dots will remain on the surface of the product to be repaired, which can be easily eliminated thanks to a grinding machine, this increases convenience several times.
Large dents include products that have a damaged area of more than 10 cm. Therefore, it is not recommended to use spot welding, it is better to use a device that will load the entire area, of course the cost of such a device is large, but it pays off immediately.
When working with the spotter, you can use a variety of elements that help in straightening, even crimped wire, hairpin or small hooks. For a perfect result, it is recommended to place the auxiliary part over the entire damaged area. Then the plane is leveled qualitatively and looks great, because the load is evenly distributed throughout the dent.
Reverse suction cups are used to eliminate damage caused by collisions with large objects. Thanks to this detail, the dent will be corrected in a matter of seconds, and minor defects can be easily corrected separately using a special tool.
To eliminate particularly large deformations of the case, it is necessary to apply the technology of preheating the surface, which makes it possible to remove some of the stress and significantly facilitate the work.
The spotter can be used not only to eliminate defects on a flat surface, it is also used to join metal plates that are installed on the body. This method is more in demand due to the fact that this technology does not require strong heating, which has a positive effect on the external condition and eliminates the possibility of deformation.
How to choose a device?
In order for the purchase to fully justify the investment and be a useful and sought-after tool, you need to know the following:
- For professional use, it is better to select a tool with maximum efficiency and various functionality. Thanks to this solution, a person will perform a dozen different jobs with maximum efficiency and minimum time costs.
- For constant work with small sheets of metal, models with double-sided welding are ideal.In the absence of such options on the market and infrequent welding, standard one-sided representatives will do.
For home use, the most common cheap devices with low power are suitable. This is quite enough for carrying out small operations for leveling household dents.
