Today, a large number of manufacturers produce welding inverters with a wide variety of characteristics. A similar technique is widely used in everyday life and in industrial production.
The first inverters appeared in the 70s of the last century. Their distinctive feature has become a kind of current conversion system. It is called inversion. The presented equipment is lightweight and comfortable to use.
Chinese welding inverters are very popular today. Their cost is acceptable to customers, and sometimes the quality is not inferior to world famous brands. How to choose the best Asian-made device will be discussed in detail below.
Device
A peculiar principle of current conversion is the welding machine (inverter). Chinese, European, domestic manufacturers, when creating such equipment, use the same principle of operation of the equipment.
Electricity from a normal household network is supplied to the inverter rectifier. There it is converted to direct current. After that, the electricity makes the transformation again. Now it has a high frequency (up to 50 kHz). Further, in the inverter unit, the AC voltage decreases. It drops to 90 V. However, the current increases. Such electricity is suitable for welding.
According to consumers, the Chinese-made welding inverter has compact dimensions and lightness. It is convenient to use. To make the right choice that meets the needs of the master, you need to pay attention to some features of the equipment presented.
Application area
When choosing Chinese welding inverters, you need to pay attention to the type of device and its scope. According to the purpose of the equipment, there are three main classes of devices.
For domestic use, it is enough to purchase models with a current strength of only 120-200 A. Such devices are capable of performing a small amount of work. In this case, the master should take long breaks after 5-8 minutes. operation of the inverter.
For the repair of sewer, plumbing communications, where it is required to weld pipes, professional-class equipment should be purchased. It is able to work without interruptions for a sufficiently long time, providing high quality welding. In this case, the inverter operates from a current of 200-300 A.
For large productions, an industrial class of devices is purchased. They are able to work without interruption for 24 hours. The welding current for such devices is up to 500 A.
Choosing a household inverter
There are several main aspects that you need to pay attention to when choosing a welding machine. A Chinese-made inverter must be made by a well-known brand. This guarantees high quality equipment.
The welding current, from which the inverter operates, must ensure the normal functioning of the equipment for a certain time. It is better to purchase a device with a power reserve of at least 30% of the operating current (at least 160 A).
Stable operation of a household type inverter is achieved when connected to a 220 V network. In houses and apartments, the power transmission line can be characterized by small voltage fluctuations (up to 15% in both directions). Inverters are insensitive to such network features. But if the voltage fluctuations exceed the threshold of 15%, you should purchase equipment with protection from similar features of the supply current.
Based on customer reviews, it can be argued that you should not purchase the cheapest devices. They almost always have only one board, on which all the main elements of the device are assembled. In the event of adverse circumstances (power surges, moisture entering the device, etc.), such a technique cannot be repaired.
Professional equipment selection
A Chinese-made welding machine (inverter) can belong to the professional class of equipment. This technique is able to withstand heavy loads, provides high quality results.
When choosing such equipment, you need to pay attention to a number of factors. The power of the working current must be selected in accordance with the thickness of the material being welded. Next, pay attention to the payload index. It corresponds to the operating time of the device, as well as the duration of breaks between cycles.
The degree of protection of the device must comply with the operating conditions. To work with high dust, high humidity, vibration, inverters designed for operation in difficult conditions should be used. The presented class of devices most often requires a connection to a network of 380 V.
Functionality
Choosing decent Chinese welding inverters, you must also pay attention to the functionality of the equipment. Depending on the method of application, there are three main groups of devices. They are used both for homework and in professional activities.
The first group includes manual arc welding machines (MMA). The second group includes semiautomatic devices. This category includes devices such as MIG, MAG. Machines for argon welding (TIG) stand out as a separate category.
Additional functions
In addition to the main functions, Chinese welding inverters can have additional operating modes. For example, it can be “Fast and the Furious arc”, which allows you to optimize the strength of the operating current, “Anti-sticking”, turning off the device in case of problems with the electrode, etc. This increases comfort during work, as evidenced by the feedback from the masters.
A display is also welcomed, as well as the ability to switch between different welding modes. Similar Chinese welding inverters are included in the class of universal devices.
Manufacturer's choice
Wanting to purchase high-quality equipment, you must be responsible for the choice of manufacturer. According to users, it is not necessary to purchase expensive varieties of equipment. This criterion does not guarantee the quality of the selected model. A good Chinese-made welding inverter can be purchased at an affordable price. The quality of the equipment presented is highly dependent on the volume of production. The larger the output, the more acceptable the cost of a unit of equipment.
Also, a worthy manufacturer is distinguished by the presence of a service center, website, instructions for operating the device, etc. Quality certificates should also be available. 90% of all inverters today are manufactured by China. Even Russian companies prefer to assemble such equipment here. Serial production allows you to create competitive products and sell them at an affordable price.
The best inverters for manual welding
To choose a worthy piece of equipment, you need to consider the rating of Chinese welding inverters, based on customer reviews. The category of the best devices for manual welding included such devices as Fubag IR 200 (9.5-10 thousand rubles), Svarog ARC 205 (14.5-15 thousand rubles). These are high-quality, time-tested devices.
The master inverter Fubag IR 200 is especially noted. It is characterized by high operating current (200 A). Due to its good power reserve, it is used for welding metal structures, cutting pipes with electrodes up to 5 mm. The performance of the device is maintained even with a significant voltage drop in the household network. There is a function of afterburner, anti-stick electrode, hot start. This device is suitable even for a novice master.
The Svarog inverter ARC 205 is produced by the Russian brand at the production facilities of the plant in China. This equipment can also be used for argon welding. The maximum operating current of the inverter is 180 A. The device has a sufficient duration of welding and positive customer reviews.
The best semiautomatic devices
Choosing the best Chinese welding inverter, the reviews of which should be studied before buying, it should be noted the devices of the semi-automatic category. It included Aurora Overman 180 devices (21.5-22 thousand rubles), Elitech IS 190P (19-19.5 thousand rubles). These are worthy representatives of welding equipment, according to users.
Aurora Overman 180 is highly reliable and affordable. This is an economical unit to operate. Due to the ability to adjust the stiffness of the current-voltage characteristics, the inverter is suitable for both thin and massive welding.
Elitech IS 190P is used for welding with the participation of ordinary and fluxed wire. Allows you to work for quite a long time without interruption. It is characterized by low power consumption.
Having considered the best Chinese welding inverters, everyone will be able to choose the best equipment option for themselves.
