Inverter-type welding machines are designed to perform a variety of tasks in the hands of skilled, qualified specialists. Such units are successfully used for various purposes in production and at home. Transformer models designed for such purposes are outdated and inefficient. That is why inverter-type welding machines have become widely used.
To make the correct selection of the required welding unit, you should 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 you need 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 welding electrodes to the parts to be joined, and there will be no negative load impulses in the power system. In addition, inverter-type welding machines require a much lower level of energy consumption, but this is by no meansaffects performance and power output. On the contrary, the efficiency of these units is an order of magnitude higher than transformer installations.
However, 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. The stability of the welding current with possible fluctuations in the mains voltage. Ensuring this parameter is provided by the manufacturing process.
2. Duplication of built-in protection systems. It provides protection against current overloads, overheating, shutdown when the maximum voltage fluctuations are exceeded, as well as power off when the operating time is exceeded.
3. There is a possibility of quite smooth regulation of the operating mode of the installation.
4. High quality welds in any position in space, as well as ensuring a minimum level of spatter of molten metal.
5. Steady 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 various metals and their alloys.
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. According to the thickness of the metal to be welded.
3. On duration. This is one of the most important characteristics for welding machines. The higher this indicator, the less the likelihood of possible overheating at increased welding currents of the unit.
