A large share of the costs is logistics costs, which determines such a significant price spread. Naturally, in budget models, cheap components are used and equipment breakdowns are not excluded.

In fairness, it should be noted that by that time the inverter will already return the funds invested in it.

Who might be interested in this offer?

The device is specially designed for beginners who plan to learn the basics of the profession. It deserves the attention of all users, without exception, for whom performance is not the determining parameter.

The Eurolux IWM190 can be left unused for a long time without fear of loss of functionality. The reason for this is the minimal set of technical capabilities of the device.

There is also a significant drawback: the holders, clips, and cables included in the kit are of poor quality. Therefore, it is advisable to purchase accessories of the best level of performance.


  • Adjustment of 10-190 A.
  • Manufactured on the basis of IGBT transistors.
  • The welding speed is high.

Only they will be able to appreciate all the possibilities of the development of German engineers. In addition to the traditionally high build quality, they are also endowed with excellent reliability.

The devices work steadily even in conditions of unstable power supply. Users can use the “Anti-jamming”, “Arc Afterburner” and “Hot start” functions. Thanks to this, all the work can be done at a decent level.

The operating range of the WIK-250 model is enclosed in the range from 20 to 250 amps, which makes it possible to perform the vast majority of welding operations.

If you need more power, then you should pay attention to a more productive analog – WIK-300, the upper amperage of which is 300A.

Both models of the well-known Kruger brand are based on IGBT transistors. This ensures fine-tuning of the equipment and its smooth operation in almost any condition.

The robust housing reliably protects the interior from shocks, excessive moisture, and dust.

It is not superfluous to recall that the generally accepted quality standards in Germany apply not only too expensive products but also to products that are available to customers.

Quality assurance has long been the hallmark of German manufacturers. Among other advantages of welding inverters WIK-250 and WIK-300, it is necessary to highlight the small size.

The welder will become an indispensable assistant for specialists with a traveling nature of work. This is also facilitated by a relatively small weight – only 5 kg.

Customers will also be pleased with the price. It is acceptable not only for professionals who earn money by welding but also for beginners who are taking their first steps in this field.

It should also be emphasized the maximum configuration. The price of the offer includes powerful cables, a shoulder strap for easy carrying, a hammered brush, and a mask.

Among the disadvantages, consumers note only the lack of a transport case.


  • Current adjustment in the range of 20-250A.
  • Easy arc start.
  • Stabilization of the welded arc during operation.
  • Protection against sticking of the electrode is provided.
  • Automatic protection against short-circuit, over-current, or over-power.

In the work, you can use electrodes with a diameter of up to 5 mm, which makes it possible to perform almost all work on the household plot or in the apartment.

The power unit works well even in conditions of unstable power supply. From the additional functionality, users will be able to take advantage of anti-jamming, arc afterburner, and hot start.

All of them will be useful for both beginners and experienced portable welders.

Getting the equipment into the rating list was largely facilitated by the good assembly and high-quality components.

There are not many disadvantages, but they are there. The most significant is the short period of continuous operation – 4 minutes.

After that, you need to let the inverter cool down for 6 minutes and you can continue. So the unit is not suitable for commercial use.


  • Lightweight.
  • Efficient cooling.
  • Good seam quality.
  • Powerful welding cables.

MMA VRD 200 by Wester

In contrast to the previous model, the VRD 200 is able to work without “smoke breaks” in the mode of up to 120 amps of welding current.

In other words, the equipment will be of interest to those who have to work a lot and often.

It is worth noting that this rule does not apply to operations with electrodes with a diameter of 5 mm. In this case, you will have to find time for breaks.

The maximum current is 200A. Of the additional functions, a standard set can attach, which is typical for most devices of this class: anti-sticking, hot start, and afterburner arc.

In addition, manufacturers have improved the safety of the structure.

The terminal voltage can reduce to a minimum level in situations where the inverter is connected to the mains but not in use.

And only in the case of a load, the voltage increases sharply to the operating parameters.

Based on the operational parameters and cost (approximately 11 thousand rubles), the Wester MMA-VRD 200 can safely attribute to the number of amateurs, but quite reliable and functional models.


  • Hot start – an increase in the current when the electrode touches the surface.
  • The fast and furious arc helps the droplet to break away from the stem electrode.
  • The “Anti-sticking” function reduces the welding current to separate the stuck electrode.
  • Operation in a wide voltage range: 150-240V.

Resanta SAI 220 to the dacha

The well-known Latvian brand has long earned a reputation in the domestic market as a manufacturer of affordable and sufficiently high-quality welding equipment.

Consider the main advantages and disadvantages of a particular model. The SAI 220 welding inverter is popular among amateur and novice welders.

The maximum that the welder gives is 220 amps. This is enough to use electrodes with a diameter of up to 5 mm, as well as to cut metal of medium thickness.

Without a break, it can run for 7 minutes out of 10, i.e. 7 minutes running and 3 minutes cooling down.

And so on through the cycle. However, the” dacha ” model was called for another reason.

It works perfectly at an unstable voltage in the power supply network and can withstand fluctuations from 160 to 260 volts.

However, buyers note a decrease in the quality of the assembly of inverters in recent years.

Another drawback is the demanding nature of the equipment. It is undesirable to allow its waterlogging or hypothermia, as this is fraught with a rapid failure of the nodes.

The semi-automatic machine is used to perform a variety of tasks. It can use in MIG or MAG modes in conjunction with the filler wire.

If there are jobs where you can not do without argon TIG welding, then you do not have to look for any other inverter.

The MIG 160 GDM copes with these tasks perfectly. But it should note that you will not be able to work with aluminum or aluminum-containing metals.

Only the TIG DC mode can implement here, and AC will require for aluminum. The arc parameters will set automatically to the equipment without operator intervention, based on the welding mode.

This feature will especially appeal to beginners, who at first do not have to choose the settings for a specific job.

Among the disadvantages, you should pay attention to a small cycle of continuous operation. This applies to cases where electrodes with a diameter of 4-5 millimeters can use.

You can, of course, work continuously with 3 mm electrodes. But then the capabilities of the device can significantly reduce.

Nevertheless, the MIG 160GDM cedar can safely attribute as the best unit presented in this rating.

The most expensive model rating: Torus 200C Super

Difficulties in choosing a purchase option can cause not only by a large range of products but also by prices.

Sometimes they are unacceptably high. Especially if we are talking about variants that can perform work in MMA and TIG modes.

Such models on store shelves can accompany to high price tags, and sellers and manufacturers in unison will justify the additional functionality of the devices can sell.

The exception to this unpleasant rule was the Torus 200S Super welding inverters.

They can design to work in both modes, generate a welding arc with a force of 200 amperes, and cost about 15,000 rubles.

The manufacturer declares the possibility of continuous operation even at maximum loads, provided that no thick metal can weld.

And welders with experience in various forums leave positive reviews about the functionality and reliability of the device.

The model will interest not only beginners but also experienced craftsmen. It easily ignites the arc and keeps it stable throughout the entire cycle.

At the same time, it does not matter which of the modes can set the controller – TIG or MMA.

  • Resistance to voltage changes – 165-242 V.
  • Use of electrodes with a diameter of up to 5 mm.
  • Direct current.
  • PV – 100% at 200A.
  • Thermostat and air cooling.

Simple and reliable BLUE WELD Prestige 186 PRO

The semi-automatic BLUE WELD Prestige 186 PRO in the rating of the best budget welding inverters is not accidental.

It has the ability to work in two modes-MMA or TIG, while it can characterize the simplicity and reliability of operation. But to a greater extent, it is suitable for performing work that requires MMA mode.

Therefore, it is perfect for those specialists who rarely have to resort to TIG welding in practice. Otherwise, you will have to face the problem of poor quality of the seams obtained in this mode of operation.

The maximum power of the welding equipment is 160 amps. Under the conditions of the maximum permissible load, it can work out 60% of the cycle.

That is, 6 minutes of welding work can perform, and 4 minutes will spend on cooling the power plant.

The tool is convenient for specialists with a traveling nature of work since its weight is only 5 kg. But there is one important circumstance that explains this paradox.

The fact is that the model will assemble in Italy, and high-quality components can use in its production.

So, unlike the Chinese counterparts, the price also includes payment for European quality standards.

Judging by the user reviews, this is true. The device can characterize good build quality and reliability.


  • Lightweight and dimensions.
  • High stability of the welding current.
  • The Function “Arc Force”, “Hot Start”, “Anti stick”.
  • Practicality and ease of use.

We draw conclusions together

The rating intentionally does not include professional models. The emphasis has shifted towards amateur equipment for a reason.

Specialists themselves will figure out what is suitable for them, and which welding inverter should not buy under any circumstances.

The review will design for beginners and welding enthusiasts who still do not have enough experience to independently choose the most suitable model.

In addition, professional equipment will cost significantly more. The cheapest deals for this segment will not be lower than $ 300.

And now let’s try to draw conclusions for ourselves. Most of the imported equipment on the domestic market is produced in China.

So there is no fundamental difference in which model to give preference to – imported or domestic-no.

The level of performance will be approximately the same since domestic installations can often make there as well.

Therefore, beginners should not pay too much attention to the” pedigree ” of the inverter.

It is better to carefully familiarize yourself with the functionality of the device, which can describe in sufficient detail in the passport of welding equipment.

After all, there is no clear answer that one of the devices presented in the rating is better, and the other is worse.

It all depends on the purpose for which it will purchase, the conditions of the power supply, and its operation. And, of course, the determining factor at the initial stage is the cost.

From this point of view, the review contains a maximum of information that will definitely help you decide on a choice.
