Why do we need an inverter-type welding semiautomatic device

The need for welding works accompanies almost every owner of a car or a private house. Therefore, it is not surprising that almost every one of them comes to the idea of ​​acquiring their own welding machine. Among ordinary inhabitants, it is especially popular inverter-type welding semiautomatic device. This type of equipment is ideal for both domestic and industrial welding. Its main advantage is compactness. Due to its small size and weight, this device is easy to store and transport to the place of work. But this is far from the only advantage.
Why do we need an inverter-type welding semiautomatic device

Almost all modern models of welding semi-automatic inverters are capable of carrying out welding work in MIG \ MAG modes. In other words, they can more easily carry out welding in an environment of both inert and active gases. In addition, many of them support the function of pulsed welding, which is indispensable when welding certain types of metal, for example, aluminum. The inverter welding semiautomatic device, thanks to the protective gas environment, allows to obtain a high-quality welded joint even when working with such complex materials as stainless steel or aluminum. The thing is that with this welding method, inert (argon, helium) or active (carbon dioxide) gases displace oxygen from the welding zone, thereby preventing oxidation of the elements being welded.

If you decide to purchase this type of welding machine for yourself, then you should familiarize yourself with some of the nuances of his choice so as not to get lost among a wide range of models. First you need to determine how often and for how long you plan to use it. If this is a one-time short-term work, then an inverter semiautomatic device of a household class will fit perfectly. If you have long garage work ahead, then it’s better not to skimp and get semi-professional or professional model.

Next, it is worth paying attention to some technical characteristics of the device, in particular its PV (duration of inclusion). This indicator displays the time interval at which the device can work without interruption. For example, if the strength of its maximum current is indicated at 300 A, and opposite the PV indicator there is a 60% mark, then this means that at maximum load the device can work without a break for no longer than 6 minutes. The higher the PV value, the longer the device can work. So, given this factor, you can purchase a model of a welding inverter semi-automatic machine in accordance with your requirements.
