Quality repair of welding machines

Welding with good reason is considered one of thethe main technological processes in the construction of buildings and in the engineering industry. This wide application also means that the repair of welding machines must be carried out at an appropriate level. Anyone who has encountered this technology is well aware of this. Today the industry produces different types of welding machines. The most deserved, if I may say so, are the transformer ones. Significantly later appeared and began to use inverters. These devices have emerged as a result of the emergence of new technologies, in particular microelectronic.

Transformer welding machines in theirthe designs are simple and reliable. 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 a solid weight. In order to move this machine to 200 kilograms, you have to use special carts. And repair of welding machines of this type also costs a pretty penny. This is because the current source and the transformer itself have large dimensions and, accordingly, the cost. Repair them preferably in specially equipped workshops.

In this context, it should be noted that the efficiency of suchdoes not exceed thirty percent. This figure increased significantly when the rheostatic resistance was replaced by a thyristor. Without going into a detailed description of the features of the electrical circuit, I must say that the thyristor device is more convenient to use. Although the repair of welding machines in this case requires knowledge of electronics. At the same time, the dimensions and weight of the device remained the same as those of its predecessor. If the breakdown occurred in the shop or on the construction site, then it will not always be possible to repair it in a short time.

This is because repairing complextechnique can only be after a fault is detected. As in medicine, first of all you need to make a diagnosis, and then perform the repair of inverter welding machines. Since it was a question of inverter units, I must say that they are modern welding equipment. In the circuit diagram, a double conversion of the electrical voltage is realized. This method 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 complexelectrical and electronic equipment, then repair of welding machines must be carried out using special stands and accurate measuring equipment. In this case, repair of the product as a whole does not take much time. In practice, it amounts to replacing the failed block 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 user-friendly. Especially it is necessary to emphasize that the cost of it is quite acceptable for a wide range of users.
