Welding machine "Resanta SAI 190": reviews, characteristics, operating instructions

Welding inverters, which are easy to use and lightweight, have replaced transformer welding units. By visiting the store, you can make a choice by looking at a wide range of welding equipment represented by dozens of models. They differ in technical characteristics and cost.

Welding inverters appeared not so long ago, in the 70s. last century. The main difference between such a device and a transformer is the method of current conversion. In an inverter, alternating current is supplied to a rectifier and converted into direct current. In the next step, the constant is converted into a high-frequency variable. At the next stage, the alternating voltage is reduced. Such conditions are necessary for welding.

High-frequency transformers are compact in size, but welding machines can have a weight that is sometimes significant. When choosing a welding inverter, several factors must be taken into account, including:

model class;
thickness of materials being welded;
intensity and volume of work;

Review of the device Resanta SAI 190 PROF

This model is more popular among professional welders. The principle of operation is similar to the model we have already considered, but there are also some additions in the form of the ARC FORCE function. It allows you to regulate the change in current strength during the welding process. Before work, the types of metals to be welded and their thickness are taken into account, then the required value is selected from 0 to 100% based on the previously determined welding current. In this case, the arc will have durability, and the metal will gain fluidity.

Advantages of the model

First of all, the modern appearance of the device catches your eye. The control panel has a protective transparent cover made of durable plastic. The digital display will show all values and set indicators for ease of operation. The number of ventilation holes has increased. There is a special handle on top for easy movement; the unit weighs about 4.8 kg. All measures taken made it possible to save consumed electricity by 30%. A power factor corrector was installed; it will ensure stability when operating with voltages from 100 V. The device also maintains its functionality when connected to many autonomous power sources.

Interesting! If the Resanta SAI-190 apparatus requires a generator with a power of at least 5.5 kW, then for the PROF model, 4.6 kW will be sufficient. In this case, the stability of operation will not be affected.

Instructions for use of the Resanta SAI 190 inverter

Connecting a device to the network occurs without special rules and requirements. The device is grounded through the plug-in cord, so the outlet must be grounded. The instructions state that for successful connection it is appropriate to install circuit breakers with a value of at least 16 A.

No work should be carried out with tools that create a dusty atmosphere at a close distance from the unit. These include grinders, electric saws or grinders. If Resanta is operating in normal mode or even idling, you should not cover it, creating restrictions on heat conduction; to ensure stable operation, the cooling system should not be irritated.

Welding is strictly prohibited in the rain or in areas with high humidity. Work with the device does not begin immediately, if it was brought in from the street, where the temperature is currently below freezing, the inverter must stand indoors without operation for at least 2 hours.

Recommendations

Do not turn off the equipment too often; if the indicator lights up, it is appropriate to simply wait a little over 15 minutes until it cools down. When work occurs in intermittent mode for 7-9 minutes, welding does not turn off, you need to wait about 3 minutes of idle operation. A harmless shutdown is only possible if no work is carried out for one hour.

To care for equipment, it is recommended to clean the internal surfaces from possible dust and dirt. The frequency depends on the degree of pollution or the time spent working in dusty areas.

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.

User manual

Before you start using Resanta SAI 190, you should definitely study the operating instructions. Among other sections, it covers safety rules. The manufacturer emphasizes that the operator must protect himself from burns. They can be caused by hot metal, slag and sparks, as well as arc radiation. All of these exposures can cause serious harm to the skin and eyes. Therefore, the welder and other people who will be in the work area should use personal protective equipment. This should include:

gloves;
boots;
headdress;
mask or welding shield.

Before starting to operate the device, it is recommended to wear a fire-resistant suit and pants that will cover all parts of the body. Before you start using the Resanta inverter, you should familiarize yourself with the rules of its operation. It is important to note that during operation, ultraviolet radiation will be emitted, which can be harmful to the skin and eyes. To prevent irreversible effects, it is necessary to use a welding helmet and protective clothing. The shield must be equipped with a light filter with a darkening degree of DIN 10.

Before turning on the unit, it is important to ensure that fire extinguishing means are available in the immediate welding area. Flammable and explosive materials should be removed to a distance of 10 m or more. It is prohibited to weld closed containers containing explosives or toxic compounds. If such a need arises, the container should be cleaned. You should not carry out welding work in an atmosphere where there is a high concentration of flammable gas, dust and flammable liquids.

Feedback on operating features

In order to extend the life of the welding inverter, according to consumers, it is necessary to follow the rules for its use. For example, it is prohibited to turn on the device during rain or in a damp room.

After reading the reviews about the Resant SAI 190, you will be able to understand that you should not use cutting tools such as electric saws and grinders next to the device being turned on. This can cause metal dust to get inside and damage the equipment.

It is prohibited to carry out welding work if the insulation of wires or cables is damaged. When the device was stored at sub-zero temperatures, consumers are advised to keep it at room temperature for 2 hours to prevent the appearance of condensation.
