Welding inverter Resanta SAI 190, 190K, 190 PN, 190 PROF

Welding equipment from Resanta company

The Resanta company was created by Latvian engineers in 1993 to produce voltage stabilizers. Later, production was expanded and production of welding equipment began. The choice was made in favor of inverter models.

Currently, thanks to reliability, convenience and beautiful design, Resanta inverters have conquered the markets of many countries. It’s no wonder that they are made in China and are tested before shipping.

Resanta welding machines

The welding inverter Resanta SAI 190 in various designs is most often used in everyday life. This choice is explained very simply:

Typically, welders use electrodes with a thickness of 3 mm. To ignite them, it is enough to set 140 A, but a current reserve is required, since you cannot cook at the maximum load; when cutting metal, the load increases, and power is lost when using an extension cord.

Resanta with a maximum current of 190 A has the necessary reserve.

In addition, a welding machine with a higher current value has a higher cost.

Thanks to special modes, it is easy to master all the subtleties of welding work. These include: accelerated ignition when touching the seam and easy removal of a stuck electrode.

general description

The design of the Resanta SAI-190 PN product is based on advanced inverter technologies based on a rectifier with pulse-modular regulation and a current stabilizer. The device is powered by a conventional single-phase 220 V power supply. This inverter welding machine has become a fairly common tool for creating the strongest possible connection of metal parts in private households, workshops and other professional or domestic situations. Using this fairly compact device, you can ensure high quality and accuracy of the weld formed by an electrode using direct current. The delivery set includes a meter cable with a special convenient electrode holder, as well as a cable with a fastening device that ensures the circuit is closed.

The inverter operating principle of the welding machine, together with the use of IGBT transistors, made it possible to make the device lightweight (about 6.9 kg) and fit it into small dimensions. This significantly increased the convenience and versatility of the device. The operator can easily carry it manually or using a shoulder strap, and can also be positioned to work in inconvenient and hard-to-reach places. This quality will definitely be appreciated by experienced welders who have had to work with heavy and bulky welding machines based on a conventional transformer.

With the use of modern technologies in the production of the Resanta SAI-190 PN device, it was possible to ensure that this small and lightweight product contains serious practical qualities. The welding current is quite significant (10-190 A), and the welding current voltage of 80 V makes it easy to maintain the arc and use electrodes up to 5 mm in diameter. The load duration (LOD) of the system reaches 70%. That is, out of a time period of 10 minutes, the device can continuously cook for as long as 7 minutes, and only 3 minutes are required for rest.

The viability of a working device is maintained by an effective forced heat removal system that prevents the device from overheating. In addition, the temperature control sensors of the device will promptly, through a light indicator, notify you of the need to take a break and give the device additional rest to recover.

The design of the welding unit Resanta SAI-190 PN is such that even a beginner in this matter can now perform high-quality welding, since the unit has become the bearer of a number of useful functions:

— “Anti Stick” – automatic reduction of the operating current, facilitating easy tearing of the electrode if it gets stuck on the surface to be welded. After the electrode is torn off, the operating parameters of the system are immediately restored.

- “hot start” (Hot Start) – a pulsed short-term increase in the operating current at the moment of contact of the electrode with the surfaces being welded, easily igniting the electric arc and facilitating the start of the welding process.

- “Arc force” – allows you to adjust the depth of penetration (arc rigidity) and control the parameters of the metal at the welding point. This function is controlled manually.

In addition, the equipment of the unit allows you to smooth out unstable supply voltage within fairly significant limits (from -30% to +10%). Thus, the device ensures stable operation and uniform penetration in the range of supply voltage fluctuations from 140 to 240 V.

Design and functionality

The Resanta SAI-190 PN inverter welding machine is a rectangular body (300x170x300 mm), assembled from a steel sheet coated with a dielectric compound that protects it from corrosion. There are special slots in the housing designed for free access of cooling air. A durable handle is attached to the top for manual transportation, and there is also a shoulder strap that frees the operator’s hands. The bottom of the case is flat and therefore holds the device firmly on the surface. The electrical safety of the housing is IP21. This means that the device is not recommended for use in high humidity (more than 90%) or during rain.

On the rear panel of the case there is a network switch and a power cord with a plug for a regular outlet.

The front panel became the location of the unit's control panel. Here, under a folding transparent cap made of durable polymer, there is a handle for continuously adjusting the welding current (10-190 A), an arc adjustment handle (0-100%), light indicators for network and emergency overheating, as well as a digital display showing the current setting . Below the control panel there are receiving ports for attaching work cables (ground cable and cable with electrode holder).

The main working element of the device is located inside the housing and is protected by it. This is a special transformer with an inverter conversion system based on pulse frequency modulation. The purpose of this component is to create a welding current with optimal operating parameters. First, the network current with a frequency of 50 Hz and a voltage of 220 V is rectified to constant, but with an increased voltage (400 V). Then this current turns into an alternating current of high frequency and is rectified again, having an output voltage of 80 V. This voltage simplifies the start of the welding process.

The workload on the welding machine leads to increased heat generation in its main operating components. Removing excess heat and preventing the temperature from rising to emergency levels is a primary task for such systems. In this case, to increase cooling efficiency, the heating surfaces of the components are equipped with finned aluminum plates, and their forced air flow is provided by a built-in electric fan.

The welding process occurs due to the fact that a closed loop of working current is created with the help of working cables. At the point in the circuit where the electrode touches the surfaces being welded, an electric arc occurs, melting the electrode and the edges being welded. When burning, the flux that coats the electrode creates a protective gas environment that prevents accelerated oxidation and the formation of slag in the melt.

Preparing for work

The welding inverter Resanta SAI-190 PN is simple in design and is almost always ready for work. You just need to connect the working cables, make the appropriate settings, turn on the power and the machine is ready to perform welding work. Necessary preparatory operations should include a detailed study of the technical instructions on safety precautions, setup and methods of working with the welding machine. Such instructions, as a rule, are an integral part of the delivery kit.

A working welding machine creates conditions under which sparks and sometimes drops of molten metal can fly in different directions from a local point of increased heating. Thus, the device may be a source of increased fire hazard. This should be taken into account when assessing the location of the upcoming work. In addition, the gases released during the welding process are harmful to the operator’s body, so the work area must be well ventilated. The welder himself must use his own protective equipment (special clothing, a special welding shield for the eyes and face, gauntlet gloves, a hat and thick leather shoes).

The manufacturer of the inverter welding machine Resanta SAI-190 PN has established a warranty period of 24 months for its product. However, by observing the basic standards for the intended operation of such a unit, it is possible to make its operation practically indefinite.
