The Resanta inverter, like a number of similar equipment, produces high current, which is a decisive factor in comparison with the classic AC transformer used for welding before the advent of more advanced equipment. In order to be able to take advantage of the benefits of welding connections of elements in a domestic environment, it is necessary to have a device such as a Resanta inverter or another analogue, since the standard parameters of the electrical network (voltage 220 V and frequency 50 Hz) are not enough to implement such tasks.

Operating principle of the inverter
Until recently, huge transformers were used to operate a welding machine using electricity. The bulkiness forced the use of vehicles to transport it, as well as the use of more than one person. With the introduction of inverter-type devices, this need has disappeared. The Resanta welding machine uses this technology.
When alternating current is supplied to the Resanta welding inverter, the process of converting it into direct current occurs, followed by distribution to transistors, which produce a reversible process of converting direct current into alternating current, the required frequency for welding.
This principle made it possible to significantly reduce the transformer, which is implemented in the device, and thanks to this, the Resanta Sai 140 welding inverter receives positive feedback from users.
Design features and model range
Inverters are presented in a wide range. Each model differs from the other primarily in the value of the maximum operating current. There are separate lines of such equipment: SAI, SAI COMPACT, SAI PROF, SAI PN. A lightweight inverter of the Resanta brand can be selected from the Compact series. At the same time, the main parameters practically do not differ from those in analogues of standard AIS devices; the only difference is more compact dimensions and less weight.
Watch the video and product review:
The SAI series inverter from Resant is equipped with a number of additional and extremely important functions for operation. The design provides protection against overheating, the so-called “anti-sticking”, “hot start” and “arc force”. The inverter of the PROF line from Resant differs from other devices in the ability to set the required value of the welding current using a digital panel. Another difference is a wider operating voltage range (up to 260 V).
The Resanta welding inverter can be used with different values of electrical parameters. The designation of each model indicates the maximum permissible operating current. Also, in the technical characteristics of such a device as a Resanta brand welder, there is a limitation on the level of current consumption. Additionally, the degree of protection of the device, the diameter of the electrode, the welding arc voltage and no-load voltage are indicated.
The welding inverter from the manufacturer Resanta is also characterized by such a parameter as the duration of the load, which allows you to estimate the duration of operation of the device at maximum load values.
The operation of this equipment is based on the principle of converting alternating mains voltage of a standard frequency value into a direct voltage of 400 V, after which the Resanta inverter welding machine converts this value into high-frequency alternating voltage.
Pros and cons of the device
If we compare Resanta brand equipment with analogues that were used before the advent of a fundamentally new type of equipment, we can highlight a number of positive qualities:
- Compact dimensions, and even the most productive Resanta inverter electric welding machine will have several times less weight and overall body dimensions;
- Easy control - due to the fact that the design provides a digital panel, thanks to which the inverter electric welding machine from the manufacturer Resanta can be controlled as simply as possible;
- Overheat protection prevents equipment failure;
- The high level of performance that distinguishes the Resanta brand inverter electric welding machine determines the rapid performance of the work, while the efficiency of the equipment can reach 95%;
- Lightness allows the unit to be transported to the required distances, thanks to which the SAI welder becomes a mobile device.
Among the positive qualities that are determined by the design features of such equipment, one can highlight the security of the units. This means that the Resanta SAI welding inverter and analogs from other lines of this manufacturer are made in a completely closed housing, which significantly reduces the likelihood of a large amount of contaminants getting inside the mechanism. Some models of equipment such as the Resanta SAI welding inverter are equipped with a special case where the device is placed. This simplifies the task of transporting it to the welding site.
Let's watch the video, the advantages and disadvantages of welders:
However, the Resanta SAI welding inverter also has its drawbacks, for example, the relatively high price of the units themselves, as well as their maintenance. Thus, these models of maximum performance (with an operating current above 300 A) will cost approximately 35,000 rubles.
Customer ratings
As for the working side of the issue, the electric welding inverter from the manufacturer Resanta of the SAI line is in good standing with users. Electrical equipment of this brand has been offered on the Russian market for more than three years.

Features of Resanta devices
The technical process of improving the performance of the device is implemented through the introduction of a special transistor current conversion board - IGBT.
The Resanta welding inverter has a design feature - the vertical arrangement of the transistor board. This design feature made it possible to avoid the accumulation of dust, and as a result, the wear resistance characteristics were increased.
The device also implements a continuous operation system, the average of which is equal to a ten-minute interval, when using less than 70% power. If during operation this indicator of the use of power resources is increased, the average time of continuous operation will be no more than 7 minutes, after which an automatic transition to idle occurs. At the same time, the idle power consumption, equal to 75 V, allows for rapid ignition of the arc, starting the immediate process of work. The company that produces the Resanta device has provided everything for its easy use.
During operation of devices of such a system, there is a high probability of overheating of the device, which can lead to its breakdown. However, Resant devices are equipped with a special indicator that informs the welder about the presence of this problem; in such cases, it is necessary to interrupt the work process for about 5 minutes, while there is no need to disconnect the device itself from the power supply. Thanks to this feature, operation of the device becomes safer for the user. To cool the device, the system uses a set of two coolers.
An intuitive control panel is located on the front of the case, and the rear contains the power switch and cable. The electric current regulator is a relay with a rotary mechanism, which allows you to control the power of use. The front panel is equipped with:
- power indicator;
