Inverter-type welding machines are designed to perform many tasks in the hands of skilled skilled professionals. Such units are successfully used for all kinds of purposes in production and in everyday life. Transformer models designed for such purposes are obsolete and inefficient. That is why inverter-type welding machines have become widely used.
To make the right selection of the required welding unit, you must determine the exact purpose of the purchased device, the required characteristics and parameters. It is also necessary to take into account the experience of firms and companies that have purchased similar products. So, when it is necessary to purchase inverter- type welding machines , reviews become the best indicator.
After purchasing a welding inverter, the consumer will easily forget about the possible welding of the 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 energy consumption, but this in no way affects productivity and output power. On the contrary, the efficiency of these units is an order of magnitude higher than transformer plants.
Nevertheless, the main advantage of these devices is that the work of welding specialists will become even safer, better and faster.
In addition, the undoubted advantages that characterize any inverter-type welding machine are:
1. Stability of the welding current with possible fluctuations in the mains voltage. The provision of this parameter is provided for by the manufacturing process.
2. Duplication of embedded security systems. It provides protection against current overloads, overheating, shutdown when exceeding the maximum voltage fluctuations, as well as turning off the power when exceeding the time of permissible operation.
3. There is the possibility of a fairly smooth adjustment of the operating mode of the installation.
4. High quality welds at any position in space, as well as ensuring a minimum level of spraying of molten metal.
5. Stable and stable burning of the electric arc, which is maintained at the required level not only with increasing voltage fluctuations, but also during gusts of wind, possible sudden movements of the worker.
6. All inverter-type welding machines are quite versatile, which allows the production of a wide variety of parts from all kinds of metals and their alloys.
The inverter-type welding machines are divided into several main groups according to various criteria:
1. According to the parameters of the supply network, single-phase and three-phase units are distinguished, connected to a voltage of 220 and 380 V.
2. The thickness of the metal to be welded.
3. The duration of the inclusion. This is one of the most important characteristics for welding machines. The higher this indicator, the less the likelihood of possible overheating with increased welding currents of the unit.
