Inverter-type welding machines: use and characteristics

Inverter-type welding machines are designed to perform a variety of tasks in the hands of skilled skilled workers. Such units are successfully used for all sorts of purposes at work and at home. Transformer models designed for such purposes are obsolete and inefficient. That is why welding machines of inverter type were widely used.

To make the correct selection of the necessary welding unit, it is necessary to determine the exact purpose of the device to be purchased, the required characteristics and parameters. It is also necessary to take into account the experience of firms and companies that purchased similar products. So, when it is necessary to purchase inverter type welding machines , reviews are the best indicator.

After purchasing a welding inverter, the consumer will easily forget about possible welding of welding electrodes to the parts to be connected, and there will be no negative load pulses in the power system. In addition, inverter-type welding machines require a much lower level of power consumption, but this in no way affects the performance and output power. On the contrary, the efficiency of these units is an order of magnitude higher than the transformer installations.

Nevertheless, the main advantage of these devices is that the work of welding specialists will become even more safe, high-quality and fast.

In addition, the undoubted advantages of any inverter type welding machine are:

1. Stability of the welding current for possible variations in the mains voltage. The provision of this parameter is provided by the manufacturing process.

2. Duplication of the built-in protection systems. Provides protection against current overloads, overheating, shutdown when exceeding the maximum voltage fluctuations, as well as turning off the power when the time allowed for permissible operation.

3. There is the possibility of a fairly smooth adjustment of the operating mode of the installation.

4. High quality welding seams at any position in space, as well as ensuring a minimum level of spraying molten metal.

5. Steady and stable combustion of the electric arc, which is maintained at the required level, not only with increasing voltage fluctuations, but also during gusts of wind, possible sharp movements of the worker.

6. All inverter-type welding machines are quite versatile, which makes it possible to produce a variety of parts from all kinds of metals and their alloys.

Inverter-type welding machines are divided into several main groups according to various characteristics:

1. The parameters of the supply network distinguish single-phase and three-phase units, connected to 220 and 380 V.

2. For the thickness of the metal to be welded.

3. By duration of activation. This is one of the most important characteristics for welding machines. The higher this value, the lower the probability of possible overheating at higher welding currents of the unit.
