Welding machine "Resanta 160": description, technical characteristics, reviews

Resanta welding machines are simply extremely popular in Russia. The equipment is reliable and, of course, convenient to use. Instruments of this brand have been known on the domestic market for a very long time - since 1993. They can be used both at home and at work.

The model range of the Resanta brand presented on the domestic market is quite wide. If desired, consumers have the opportunity to purchase equipment of this brand with a variety of technical characteristics and functionality. At the same time, one of the most popular models from this manufacturer is the Resanta 160 device. This equipment has received simply excellent consumer reviews.

Who releases

is a Latvian company SIA RESANTA. This company began its activities in 1993. Initially, it was engaged only in the production of voltage stabilizers. These company products are also well known throughout the former USSR.

The quality of the devices is really quite good. And therefore it has always enjoyed enormous popularity among consumers. Thanks to this, by 2008 the company was able to increase its production volumes 10 times compared to 1993.

Today, in addition to voltage stabilizers, the company produces compressors, multimeters, thermal equipment, testers, etc. And of course, this company also supplies high-quality inverters to the market.

Main advantages of the model

The Resanta 160 welding machine has many advantages. These include, for example:

high level of operating current;
ability to work at low voltage;
Possibility of use at unstable network voltage.

This device is also compact. It is believed that it is simply ideal for work in domestic conditions. But, unlike many other Resant models, this equipment can also be used in production. This device belongs to the inverter type devices. That is, its design contains a unit designed to convert alternating current from the network into direct current.

Correct connection of the inverter

Connecting the inverter of this model and fully preparing it for operation is not particularly difficult. This is evidenced by the reviews of its owners. Depending on what electrodes you are going to work with and what welding work to perform, you select a scheme (direct or reverse) for connecting the cable with a holder and a grounding cable. These cables are connected to the power terminals located on the front of the device. After connecting the cables, check whether the power switch is turned off, only after that the inverter is connected to the electrical network using a socket.

The cost of SAI-160 on the company’s official website is 7,300 rubles

Before pressing the power switch, you must set the welding current regulator to the minimum value and move the power switch to the “On” position. After turning on the device, you can already set the welding current to the required value. In this regard, you can be guided by the following recommended values: when welding with electrodes with a maximum permissible diameter of 4 mm, choose a maximum current of 160 A, when welding with electrodes Ø 3.2 mm - 140 A, and so on.

Turning off the machine after completing welding work is performed in the reverse order: turn the current regulator to its minimum value, turn the power switch to the “Off” position, disconnect the inverter from the electrical network, and disconnect the power cables.

It is very important to adhere to exactly this algorithm for turning on and off the equipment: this will allow you to keep it in working condition for a long time.

Why and who needs a welding machine

In a farmstead, on a summer cottage, in a garage or a small production workshop, you can’t do without a welding machine.

Long gone are the days when they used a classic transformer welder, which weighed well over 50 kilograms, and when working, the light “sagged” throughout the entire street or in a garage cooperative.

With the advent of inverters, the situation has changed dramatically. Compactness, light weight, almost silent operation and ease of use have opened up the world of welding for many. Welding a fence at the dacha, making shelves in the garage or welding hinges that came off the door - with the advent of inverters, this has ceased to be a problem.

Despite the many “classmates”, good reviews and an adequate price of the Resanta SAI 160 welding machine sway the buyer in their direction.

Types of welders

This inverter converts alternating current from the electrical network into direct current. Resanta differs from similar devices in its circuitry that has stood the test of time. Integrated chips control the transformation of electrical current, which provides flexibility in its use.

For garden, dacha and garage use, experts recommend the Resanta SAI 160, Resanta SAI 160 K and Resanta SAI 160 PN models, the price of which is not much higher.

The model with the index “K” denotes the “Compact” series, it is lighter by a kilogram, and the “PN” model, which can work with a voltage of 140-160V, is suitable for gardening and garage realities.

You can find these welding machines in different stores at prices ranging from 5,500 to 7,000 rubles.

Characteristics of the welding machine Resanta SAI 160

Operating current 10 - 160 A
The diameter of the electrodes is from 1.5 to 4 mm.
"Hot start" and "Anti-sticking".
Weight 4.5 kg.

The Resanta SAI 160 welding machine is a basic model, operating on a voltage of 220 volts +/- small deviations: plus 10%, up to 240 volts, minus 30%, up to 156 volts.

In practice, the inverter cooks normally at 190; if the voltage is lower, you have to change the electrodes to smaller ones. For holiday villages and rural areas, where voltage drops in the network are common, the Resanta SAI 160 PN inverter welding machine is suitable; reviews from owners about it are mostly positive.

Yuri, 36 years old, Taganrog.

The operating mode of these devices is 70/30%. These numbers mean that out of 10 minutes you can cook for 7 minutes, and rest for 3 minutes while waiting for the device to cool down.

Pros of s/a Resanta SAI 160

The advantage of Resanta SAI 160 welding machines is that they operate on a 220 V network. The protection class of these inverters is IP 21. This means that grounding occurs through the power cord. Resanta SAI 160 works on 10-16A machines, but as practice has shown, 10A machines can no longer cope with the maximum welding current.

The belt will allow you to carry the device with you if you need to frequently move along the workpiece being welded or if it is not possible to put the device on the ground. In this case, the Resanta SAI 160 K will be a good choice, reviews of which on the Internet note the low weight of the inverter.

Features of operation of inverter welding machines Resanta SAI 160

There should be no operating electric saws, angle grinders, grinding machines or tools near the operating inverter, which raise dust when working with them. The inverters are equipped with forced cooling - coolers; if there is a large amount of dust, it will get inside the device. For the same reason, there is no need to place the inverter on the ground; it is better to lay a rubber mat or a sheet of plywood.
Do not cover the welding machine during operation. The reason is the same - the coolers cannot cope with the cooling, the device will overheat and turn off.
You cannot work in the rain. No comments.
If the welding machine is brought into a warm room from the street in winter, you should wait at least 2 hours so that the condensation that has formed in the machine has time to dry.

“Anti-stick” and “Hot start” make life easier for beginners in welding. Those who welded with old transformer-type welding machines remember well how difficult it is to ignite an arc. Resanta SAI 160 inverters relieve their owners from this problem.

“Hot start” easily ignites the arc, sharply increasing the current when the electrode touches the surface and creating a high temperature at the point of contact of the electrode.
“Anti-sticking,” on the contrary, independently reduces the current strength in the event of the electrode sticking to the surfaces being welded. As a result, the heating decreases and the electrode comes off easily.

Malfunctions and shortcomings of welding machines Resanta SAI 160

Even the most advanced equipment can fail, and Resanta SAI 160 inverters are no exception. Malfunctions that arise can be divided into two categories - manufacturing defects and violation of operating conditions and requirements.

Microchip malfunction. This breakdown can be caused by a manufacturer’s defect or dust getting into the device, for example, when working in a dirty, poorly ventilated area or if “dusty” work is carried out near the inverter.
Frequent and premature shutdowns of the device due to its overheating. In this case, a protective relay is activated, designed to protect the expensive inverter from damage. The reason is most often simple - either poor contact of any circuit inside the device, which always leads to overheating, or again a violation of the rules for operating the device, for example, when the welder is covered with something during operation.

PS Many users of Resanta SAI 160 welding inverters are dissatisfied with the short welding wires. They are one and a half meters long, which is not always convenient when working with an inverter.

Owners independently change welding wires to longer ones, which is not a violation of operating rules. The main thing in this case is that the new wires have a cross-section of at least 25 mm/sq.

By the way, increasing the length of the welding wires will lead to a loss of welding current power, but for most owners who use an inverter in the country and in the garage this is not critical.

General description of the model

One of the undoubted advantages of the Resanta SAI 160 inverter welding machines is a wide range of current strength. At the same time, the wizard can set the required value manually. Thanks to this feature of the device, it can be used both for delicate welding using thin electrodes and, for example, for cutting thick metal.

The housing of the Resanta 160 welding machine is equipped with fans. These elements perfectly complement the natural air cooling of the device. If desired, models 160 can be used in low power networks. It is also possible to connect them through generators.

Of course, this model has all the functions that distinguish modern inverters from previously produced less advanced and convenient devices:

preventing sticking;
hot start.

If the electrode sticks to the surface being welded, the current in the machine automatically decreases. And this, in turn, reduces heating. As a result, the electrode easily comes off the metal.

At the very beginning of operation of the Resanta 160 inverter, the current increases sharply. This leads to rapid heating in the place where the electrode contacts the metal surface. Therefore, a welder using this equipment never has problems with electrode sticking at the beginning of work.

Principle of operation

The neat and compact body of this equipment is made of metal; on its front panel there are power connectors to which welding cables are connected. In addition, on the front panel there is a knob for adjusting the current strength, as well as two indicators: “Network” and “Overheat”. To ensure forced ventilation of the internal elements of the inverter, there are special openings in its housing, which in no case should be blocked to prevent overheating.

The operation of the inverter is ensured by its electrical circuit, in which several transformations of the electric current coming from the regular network occur. First, the alternating current supplied to such a circuit is converted into direct current, which also happens to the voltage. Then, in the second stage, both voltage and current again turn into variables, but their frequency increases significantly (current - from 20 to 50 kHz). Reducing the voltage, which also occurs in the second stage, makes it possible to obtain a high-frequency welding current of the required strength.

Mains voltage and electrode diameter

The technical characteristics of the welding machine "Resanta 160" are really quite good. The ease of use, and therefore the popularity among consumers of this model, is explained, of course, primarily by the thoughtfulness of its design. In everyday life, the use of 160 devices became possible due to the fact that they operate from a 220 V network. For industrial equipment of this type, as is known, 380 V is required. Previously produced welding machines were designed to operate from precisely such networks.

The maximum current of this model, as can be judged by its name, is 160 A (with a minimum of 10 A). If necessary, welding can be performed with the Resanata 160 machine using fairly thick electrodes. The maximum diameter of the latter for this model is 4 mm. The minimum electrode diameter for the device is 1.6 mm.

general description

The Resanta SAI-160K device is a portable inverter-type device for manual welding, capable of providing full-fledged welding work at the household (and not only) level. The unit is simply connected to a household power supply with a voltage of 220+/-10% V and is designed to work with coated welding electrodes and a metal core diameter of up to 4 mm inclusive.

Welded joints of metal elements are quite common both in production and in domestic conditions. Welding transforms different iron elements into a single, strong, non-demountable structure, the strength of which is incomparable to anything else. As a rule, this connection method is used to obtain the most reliable connection where it is impossible or impossible to use a threaded connection. Manual welding is quite widespread both in everyday life and in production (any construction, installation, repair work, etc.). And if previously, to carry out such work, bulky and heavy units were required, then with the advent of inverter devices, these shortcomings were eliminated.

The described Resanta SAI-160K unit is one of the most convenient and compact tools for performing work of this kind. He can do almost any welding operation. Light weight and dimensions, a comfortable and durable shoulder strap allow the welder to easily move the device to the location required for work.

The system includes working cables (power with electrode holder and grounding cable). The length of each working cable SAI-160K is 2 meters. The system also has a power cable (170 cm) with a plug. If necessary, you can use an extension cord of the appropriate cross-section.

A special welding helmet and other personal protective equipment must be purchased separately.

To make the welder’s work easier (especially for beginners), the designers of Resanta SAI welding machines have created such a useful function as a “hot start” (HOT START). At the moment the electrode is sufficiently close to the elements being welded, the system automatically creates an increased operating current pulse, which contributes to the rapid formation of an electric arc. At the same time, the welding process is greatly facilitated.

The “anti-stick” function (ANTI STICK), also characteristic of all Resanta SAI devices, in turn is designed to facilitate the work of the welder, eliminating the phenomenon of electrode sticking during the arc burning period. In this situation, the device automatically reduces the welding current, facilitating easy tearing of the electrode. Immediately after this, the system restores operating parameters.

The main part of Resanta welding machines is made on the basis of high-tech IGBT transistors. As a result, it was possible to achieve a significant increase in the service life of the system, as well as significantly reduce its dimensions and weight. The transistor board is typically located in a vertical plane, which prevents the accumulation of dust and, as a result, unnecessary overheating.

Another characteristic feature of the system is the on-time (ON). This is a value that characterizes the ability of the device to operate continuously over a certain period of time. The basis was a 10-minute time interval. For the SAI-160K device, this parameter is 70% at maximum load. This means that welding can be carried out continuously for 7 minutes out of 10 and 3 minutes - a break at idle.

The welding machine of this model has a fairly significant open circuit voltage (80 V). This facilitates easy and quick ignition of the electric arc, which allows you to work with non-ferrous metals.

The creators of the welding machine also took care of its safe use. The main danger for devices of this kind is overheating, which can cause breakdown of the unit and other undesirable consequences. Resanta SAI-160K has a special warning system, which turns on (before dangerous overheating) an emergency indicator light. When the indicator lights up, it indicates the need to pause welding work. A 5-minute break is enough to restore the unit’s functionality. There is no need to disconnect it from the power supply.

Design and functionality

The housing of the Resanta SAI-160K welding machine has a compact rectangular shape, dimensions 260x130x190 mm and is made of high-quality sheet metal with a protective coating. The flat base of the case allows it to be placed stably on any surface, even with a slight slope. There are specially made slots on the sides of the housing through which ambient air can easily circulate, cooling the main transformer. The electrical safety of the housing meets the criteria of class IP 21 (protection against the ingress of foreign objects, but work should be done in a fairly dry atmosphere).

The switch and power cable are located on the rear panel of the case, and the control panel is located on the front panel. It is very simple, understandable and will allow even a beginner to understand it. Here the designers placed a rotary regulator for operating current from 10 to 160 A, a network indicator and an indicator warning of the approach of emergency overheating. On the same panel there are terminals for connecting the power cable with the electrode holder and the cable that ensures the closure of the electrical circuit for the welding process. At the top of the case there are fastenings for a shoulder strap.

All components of the welding machine are located inside the housing, ensuring its safe functionality within the limits of technical capabilities. The main element in this matter is a conversion transformer with special equipment that converts alternating current with a frequency of 50 Hz (power grid) into direct current, followed by its reverse conversion into alternating current, but with a much higher frequency (more than 20 kHz). Thus, it is possible to increase the current to 160 A at a voltage of 80 V. These transformations make it possible to achieve significant quality of the weld, which is especially important for the final result. The transformer has a finned light alloy surface that promotes intense heat transfer and efficient cooling of the element. This is also facilitated by two built-in fans.

Reliable operation and safety of the Resanta SAI-160K welding machine is ensured by a special protective system. Temperature sensors detect the approach of dangerous overheating in advance and warn the user by turning on the emergency indicator.

The principle of welding is that between the edges to be joined and the electrode close to them, with the help of a working current, an electric arc lights up, heating them to the melting temperature. The molten electrode firmly welds the joined edges together, forming a weld seam. The hot start and anti-stick functions are provided by automatic adjustment of the operating current. The initial approach of the electrode to the edges provides an increased impulse for rapid ignition of the arc. Then the current drops sharply, preventing the electrode from sticking. The special coating of the electrode consists of a special flux and prevents direct contact of the melt with oxygen and nitrogen impurities contained in the surrounding air. The quality of the weld directly affects the strength of the joint, so it must be checked. To do this, you should beat off the slag deposit with a hammer and make sure that the seam is uniform and intact.

Preparation for work and safety measures

The Resanta SAI-160K inverter welding machine is not complicated. Almost any adult can prepare it for work and operate it. Initially, you should take into account and ensure some safety points in order to prevent electric shock and other unpleasant consequences. The device is grounded through the power cord, so you should make sure that the socket has the appropriate equipment. After the working cables have been connected to the required terminals, you can plug the power cable into the outlet (the “mains” toggle switch should be off and the operating current regulator should be in the lowest position). Now you can turn on the device and set the required operating current. After completing welding work, turn off the device in the reverse order.

If welding work is carried out indoors rather than outdoors, care must be taken to ensure that it is well ventilated and that there are no flammable materials or gases in it. When starting work, the user must use protective equipment (gloves, headgear, special clothing and a special mask to protect the eyes and face). In addition, it is necessary to strictly adhere to fire safety rules and requirements for the safe operation of equipment of this kind.

The manufacturer of the welding inverter Resanta SAI-160K provides a guarantee for its flawless operation for 24 months from the date of its official sale.

Open circuit voltage

This figure for the model is 85 V. This figure, in comparison with many other modern devices, is quite large. This no-load voltage makes it very easy to ignite the arc in Resanta 160 devices. However, at the same time, the high value of 85 V, unfortunately, somewhat reduces the safety of use (discharge from accidental contact can cause harm to health) of this equipment. However, model 160, like most other modern ones, is equipped with a special function of protection against electric shock to the master.

Cooling system and protection class

The Resanta 160 model can serve in the household for a very long time. A good welding machine nowadays should also have an effective cooling system. Of course, when developing the Resanta 160, the designers took this into account. As soon as the equipment warms up to a certain temperature during operation, its fans automatically turn on. “Resanata 160” has two of the latter, which is a good indicator for a modern budget device.

When purchasing an inverter, you should also pay attention to its protection class. Of course, carrying out welding work, for example, in the rain using such equipment is strictly prohibited. However, the higher the protection class of the model, the better, of course. After all, anything can happen in life and the device can, for example, be forgotten on the street. Or it may suddenly rain while working. Resanta 160 models belong to IP21 protection class. This means that they can remain safe in direct rain. When oblique, it is better not to use them under any circumstances.

Reviews about the model

The opinion of consumers on the Resanta 160 welding machines, as already mentioned, is simply excellent. The undoubted advantages of this model include, of course, the ability to work at unstable or low voltage, as well as compactness and low weight. Another advantage of this inverter is its relatively low cost. The price for Resanta 160 devices is approximately 7,000 rubles. That is, this equipment costs much less than much other similar modern equipment.

The 160 inverter rarely requires repairs. The equipment is quite reliable and durable. However, if it breaks, it will not be particularly difficult to repair it. Service points specializing in this brand are available in many cities of the country.

Thus, this model has many advantages. This is a really good welding machine. But this inverter, of course, according to consumers, also has some disadvantages. Masters include, first of all, as already mentioned, short cables. Also, some consumers note the fact that defects are sometimes found in batches of Resanta 160. In this case, the device must be repaired or replaced with a new one.

RESANTA SAI-160

Shoka Love, 08/01/2018

Pros: I’ve been using it since 2013, it worked as it should until I broke it myself. I cook black and stainless steel from 1.2 to 5 mm with electrodes from 2 to 4 mm. It actually produces somewhere around 140A, maybe even more. at low currents with thin pieces of iron it works tolerably, although sometimes it sticks.

Disadvantages: the holder fell apart, the copper wire on the crocodile melted, the connectors on the cables cracked, the cables fell out of the connectors 2 times due to my rude attitude (I lifted the device by the cables). After 4 years of operation, I bought a new holder and a crocodile with long cables KG16, I don’t consider this a problem.

The antistick works strangely (if it is there at all). Sometimes the electrode sticks completely, sometimes I can’t get it off, I bite it off.

The arc of the device is not very stable, sometimes it is interrupted (especially on Kobelko and Uoni11 electrodes).

Comment: I am very pleased with the device. After reading other people's reviews, I realized that Resanta has deteriorated the quality and you can now buy its products only with an eye to possible repairs (read: the proximity of service centers and the integrity of the sellers).

For a high-quality weld, I recommend Kobelko electrodes (but they are difficult to ignite and the arc sometimes goes out on its own) and ESAB Ok46. yes, they are expensive. electrodes “ano”, “mp3”, etc. It's very easy to weld, but they produce more slag than iron; welding skills are required.

I used it to weld a fence, gates, wheelbarrows, a chimney, garden tools and fishing utensils, mufflers, a heat accumulator, welded a screw pile foundation and even fused cut slots of meat grinders. It’s impossible to list everything. The device has paid for itself more than a dozen times. I cook chernukha and nerzha.
