The contact spot welding machine (also called spotter) is an indispensable tool in absolutely any type of production.
Distinguish:
- The machine of spot welding of high power, which has large mass-dimensional indicators.
- Low power spot welding machine with convenient compact dimensions.
Such units are widely used in manufacturers of various parts, in particular, in the production of automobiles.
The compact spot welding machine can be used in the process of straightening various body panels. In this case, some irreplaceable elements are additionally installed on it, such as a fixing system, a return hammer, and various materials used in the manufacturing process. The fastener system is carried out by means of loops and a corrugated wire. Such extended equipment makes the spot welding machine more functional and economical.
The purchase of this unit in such a supplemented and improved configuration has a positive effect on the process, and reduces operating costs by almost 20 percent. Of course, any additional parts can be purchased at retail outlets, however, it is much easier to install one device than to look for a place for three, for example.
It is not advisable to purchase the so-called spotter and use it for ordinary body straightening , since such an action will lead to the inability to quickly switch the leveling devices. In addition, the unavoidable large size (which can significantly reduce the speed of the process) will become a definite minus of using this method. Many manufacturers have come to the following decision: two types of units are bought at once: a spot welding machine with large and low power. Moreover, each of the previously described machines has the required equipment, which can significantly increase the efficiency and productivity, as well as increase the output speed of the finished product in this area.
For example, body panels are welded using special tongs that are installed on high power devices, since a similar application on low power electric machines is not able to provide the required level of quality and reliability. In addition to this, high-power units are equipped with all kinds of shoulders for attaching ticks. This supplement must be present without fail. Less strictly related to the presence in the basic configuration of the electrodes and the cooling system, which is necessary to prevent overheating and premature shutdown of the welding machine. The cooling units can be made in two variations: water and air. A water cooling system is preferred over an air cooling option. However, high-quality spot welding machines can be produced with air cooling systems . At the same time, they cope perfectly with the tasks assigned to them, preventing undesirable overheating.
In conclusion, it should be noted that spotters can be produced for voltages of 220 V and 380 V. There are no significant differences in the characteristics of power, quality and functionality.
