Welding with good reason is considered one of the main technological processes in the construction of buildings and in the engineering industry. Such widespread use also implies that the repair of welding machines must be carried out at the appropriate level. Everyone who has come across this technology is well aware of this. Today, the industry produces various types of welding machines. The most deserved, so to speak, are transformer ones. Much later, inverters appeared and began to be used. These devices appeared as a result of the advent of new technologies, in particular microelectronic.
Transformer welding machines are simple and reliable in design. They are able to work for a long period of time and do not require special operating and storage conditions. At the same time, the device has large dimensions and solid weight. In order to move this colossus to 200 kilograms, you have to use special trolleys. And repair of welding machines of this type also costs a pretty penny. This is due to the fact that the
current source and the transformer itself are large and, accordingly, the cost. It is preferable to repair them in specially equipped workshops.
In this context, it should be noted that the efficiency of such an apparatus does not exceed thirty percent. This figure increased significantly when replacing the rheostat resistance with a thyristor. Without going into a detailed description of the features of the electrical circuit, it must be said that the thyristor apparatus is more convenient to use. Although the repair of welding machines in this case already requires knowledge of electronics. At the same time, the dimensions and weight of the device remained the same as its predecessor. If the breakdown occurred in the workshop or on the construction site, then it will not always be possible to repair it in a short time.
This is because complex equipment can only be repaired after a malfunction is identified. As in medicine, first of all, you need to make a diagnosis, and then already repair inverter welding machines. Since we were talking about inverter units, it must be said that they are modern welding equipment. In the circuit diagram, double conversion of electrical voltage is implemented. This technique allowed to significantly increase the efficiency of the device - up to ninety percent. Plus, its dimensions became tens of times smaller. Suffice it to say that household appliances have a weight not exceeding 4 kilograms.
Since the inverter is a complex electrical and electronic device, the repair of welding machines has to be performed using special stands and accurate measuring equipment. At the same time, repairing the product as a whole does not take much time. In practice, it boils down to replacing a failed unit with a working one. And already in the laboratory, this unit will be repaired and adjusted to the appropriate parameters. This approach makes the inverter very convenient to use. It should be emphasized that its cost is quite acceptable for a wide range of users.
