The real revolution in the field of welding equipment was the appearance of inverters. These modern devices have won the hearts of domestic users due to their compactness, light weight and good performance. And if the first models, due to the high price, could only be appreciated by professionals, today inverters have become affordable for garage and home craftsmen. The range of these specialized products in the domestic market has also expanded. The trading network offers different devices by price, functionality and purpose. In order not to make a mistake with the choice, it is useful to get acquainted with the recommendations of experts.
Criteria for choosing a welding inverter
- First of all, you should decide on type of weldingwhich will implement the inverter. Some models are designed for manual arc welding, others allow you to work in an argon environment, and others are semi-automatic with a protective environment in the form of carbon dioxide.
- Each inverter has certain technical parameters. One of the main indicators is maximum current. But it is supplemented by the duration of the device on at maximum current, this value is expressed as a percentage. The higher the PV, the longer you can cook metal without fear of overheating the inverter.
- For domestic users, an important characteristic is input voltage rangeat which the device is capable of operating. Therefore, it makes sense to measure this value in the mains before buying, especially during drops.
- Modern welders are equipped with a number of useful features that help in the work. arc force automatically adjusts the current strength of the device depending on the load. hot start allows the use of poor quality electrodes. And the anti-stick mode prevents the electrodes from sticking to the metal, dropping the current and voltage.
- Under equal conditions, an inverter with less weight and compact overall dimensions looks more convenient.
Our review includes the best welding inverters. When compiling the rating, the following criteria were taken into account:
- purpose of the device;
- type of welding;
- technical specifications;
- expert opinion;
