15 best welding machines with AliExpress

Electric arc welding is a convenient and technological method of joining metal products, which is widely used in all branches of construction, industry and everyday life. Owners of their own houses, cottages, farms often need to weld reinforcement, profile pipes and other parts of metal structures. The welding machine is required for the connection of sheet metal parts, repair or restoration of fences, canopies and gazebos, garden structures.

A decade ago, for domestic use, it was possible to buy only two versions of welding machines: a welding transformer operating on alternating current or a welding rectifier, in which the transformer was supplemented with a diode circuit to produce a direct current arc. Both options were quite large, heavy, not very stable in work and required quite serious skills from the welder.

With the advent of inverter welding machines on the market, the situation has changed dramatically. Despite the fact that the device itself has become more complex and required the use of serious technologies for the conversion and stabilization of current parameters, their dimensions and weight have decreased several times, and the comfort of work has increased many times. Now even a novice welder without problems can weld parts with the formation of a sufficiently high-quality weld.

On AliExpress presents a wide range of inverter welding machines – from compact, small power, to almost universal semi-automatic. This review lists only the highest quality devices from proven manufacturers. The rating is compiled with the analysis of a large number of real user reviews.

The best compact welding machines

The development of technology allows you to create just tiny welders - in our review there are instances of 2.5-3 kg in weight! Of course, they are not too powerful: for the most miniature, the maximum operating current does not exceed 120 A, but those who are interested in tool mobility do not consider this a significant drawback. For small welding work on the repair of metal structures, work in cramped conditions, body repair compact devices - the best choice.

5 Zojan MINI MMA-250

A welding machine that fits on the palm of your hand. The maximum current is not more than 120 A, and the weight is only 2.5 kg. The device has relatively recently appeared on sale on AliExpress, but all the buyers who left feedback, put him five stars. Welding is possible with the use of an electrode with a diameter of no more than 3 mm, but for small housework this is quite enough.

At the same time, the device has overload protection, splash-proof casing design and arc stabilization system. The big drawback is the lack of free delivery in the Russian Federation. Shipping costs will be more than half the price of the welder. But if in the future the seller optimizes logistics, the device has every chance of reaching the top of sales.

4 RESANTA SAI 190K

This device has the maximum operating current parameter in the category - 190 A, but its weight does not exceed 4 kg. Like the rest of the compact line models, it can operate in the mains voltage range from 140 V to 260 V. The maximum electrode diameter is 5 mm.

Most buyers praise prompt delivery and good service. Reliability and convenience in work - a distinctive feature of the welding inverter AIS 190. Its parameters are sufficient for most of the work required in a private house or at the cottage.

3 RESANTA SAI 160K

The welding equipment of this brand has long established itself as reliable and high-quality. Now Resanta’s phones are also available on AliExpress, and the warehouse is located in Russia, so buyers mark a very fast delivery - on average from three to six days. According to numerous reviews, the welding inverter with a maximum current of 160 A is a reliable device, comfortable in use. It works at a voltage of 140 V, which is a record in this category.

Systems of anti-sticking, easy start and afterburner arc are well thought out and work flawlessly. The nominal on-time at a maximum current of 160 A is 70% thanks to the integrated cooling system. The weight is only 3.4 kg. Buyers note low power consumption and stable operation even in the heat of +40 degrees. The disadvantage is traditionally short wires.

2 Dekopro DKA-120

Although the manufacturer indicates the maximum electrode size for this welding machine – 3mm, many users note that even with 4 mm it cooks well, which is surprising, given the maximum current of 120 A. The small dimensions and weight of 3.45 kg allow the use of DKA-120 in the production of high-rise works

The nominal duration of work is 40%, which is somewhat less than that of other popular models in the class, but in the complete set there is a brush and a face shield. This is the most sold device in the compact category, and in more than 500 reviews, most of the ratings are excellent. Some buyers point out problems with delivery and packaging, the quality of the device itself is at its best.

1 Kolner KIWM 180 i

This compact welding inverter has a weight of only 2.8 kg with a maximum operating current of 180 A. At the same time, it implements a number of advanced technologies:

• automatic activation when the electrode touches the surface;
• the HOT START function provides an easy ignition of the arc;
• anti-sticking function;
• IGBT technology provides high arc stability and good welding quality.

An important characteristic of the device in domestic conditions is its ability to operate in a wide voltage range: it can be used even with a network voltage of 150V. Users note a convenient handle and a carrying strap, as well as a good quality of the protective mask that comes with the device. Among the shortcomings mentioned are rather short wires (2 m).

The most powerful household welding machines

In the case when it is necessary to weld channel bars, beams, thick-walled pipes or large-diameter fittings, as well as long work is required, customers consider buying invertors with a maximum current of 220-250 A. This category contains five best-selling devices on AliExpress great reviews and well-established companies.

5 Stavr SAI-220 BTE

It may seem that for a device with a maximum current of 220 A, the cost of the SAI-220 welding inverter is somewhat overestimated, but, firstly, it has a good protective mask and brush, and, secondly, with a current of 160 A you can work without interruptions on cooling: the duty cycle in this mode is 100%. A good indicator and the maximum diameter of the electrode is 6 mm.

Buyers note fast delivery from a warehouse in the Russian Federation - on average, during the week, and stable operation with reduced network voltage. The disadvantage - a little more weight - 6.5 kg.

4 Sturm! AW97I125

Considering the pleasant price and free shipping from a warehouse in Russia, the Sturm welding machine! AW97I125 has all chances to stay in the top sales for a long time. It is adapted to the network with voltage fluctuations from 160 to 250 V and a switching time of 60% at a maximum current of 250 A. All popular functions, including the arc stabilization system and protection against overheating, are also available.

Users praise the small weight (4.7 kg) and compactness of the device, noting that in maximum modes it lacks some power.

3 FORGELO

The welding machine can not be evaluated in appearance, and the manufacturers of this model are well aware. There is nothing extraordinary here, either in design or in stuffing. The usual inverter with operating modes from 25 to 300 amperes. It is quite enough both for household works, and for small production. There is also protection from overheating, and according to customer feedback, it works properly, although at maximum load the response rate increases, which is also very common.

But there are some advantages. For example, an electronic display. With it, you will be better able to control the output voltage, adjustable with two handles. But the main advantage is the price. Here it is as democratic as possible, especially for a device of relatively high power. By the way, the manufacturer company is well known, both in China and beyond. It has established itself, releasing reliable welding technology in the middle price segment, and successfully competes with well-known brands.

2 RESANTA SAI 250K

Resant's 250-amp welding inverter from the compact series has earned a reputation as a universal device for home or small production. It has a really small weight - 4.6 kg, excellent power, which allows electrodes to work up to 6 mm inclusive and the inclusion time is 70%, which is the best indicator in the category.

With an allowable voltage range of 200-240 V and user-friendly anti-sticking, hot start functions (idle voltage of about 80 V facilitates arc ignition) and overheat warnings, this device has only one traditional drawback - short wires only 2 m long.

1 FORGELO Arc Welding

Arc, or as it is also called electrode welding, is used to fasten steel elements. Such devices weld ferrous metals, but are not capable of combining aluminum or copper. For this purpose, welding in an argon environment is used, and this is a completely different apparatus. But do not immediately buy a few tools. We have before us the best combined apparatus capable of welding in both dry and gas environments.

Switching between modes occurs by pressing a single button. If necessary, a cylinder with argon is connected to it, and a special holder, which, unfortunately, is not included, which is very strange. In fact, the car is very comfortable, but you should not pin high hopes on it. Argon welding is a completely different technology, and it will not be possible to fully implement it. But you can use this welding machine in everyday life, welding various small parts made of aluminum, copper or brass. By the way, the price is quite democratic. It should be noted that machines for welding in an argon environment are much more expensive, and they look more cumbersome.

The best machines for semi-automatic welding

Arc welding is used to join parts made of thick metal.You are unlikely to be able to weld thin tin with an electrode, although some manufacturers claim that their devices are capable of it. The fact is that the electrode arc creates an incredible temperature around itself, which simply melts the metal, thereby connecting it. But, as you know, under the influence of high temperatures, the metal begins to deform, and if the thick-walled steel returns to its original shape after deformation, the tin loses its structure, or more simply, warps.

To connect such parts used semi-automatic welding. Here, instead of the electrode, thin copper-plated wire is used, which is fed to the holder at a constant speed. At the moment of contact of the wire with the surface, a carbon dioxide vacuum is formed around the arc, which prevents the metal from losing its shape and overheating. Carbon dioxide is connected separately, and is an integral part of such work. Previously, similar welding machines were used only in production, but today they are available to everyone, and you can buy them on Aliexpress, at very reasonable prices. However, it should be understood that to work with such an inverter requires a certain skill and experience. When using for the first time, nothing can happen, because, unlike electrode welding, there are many parameters that need to be adjusted. In particular, the wire feed rate, as well as the intensity of carbon dioxide injection. All parameters must be adjusted to each other, and they change depending on what you weld.

Most inverters presented on AliExpress cannot be used on professional production. As a rule, they lack power, and in fact they are household tools. With homework, such devices will cope without difficulty, but the tasks are more difficult for them to be impossible. The truth is, there is a more powerful, professional tool on this site and one of them is in front of us.

This is a semi-automatic welding machine of maximum power with the ability to fine tune and a memory function that remembers the set parameters and can later automatically enter them on the machine. In addition, the machine is able to work as a plasma cutter and has a special socket for connecting the gas. The wire is located in the front, which does not look very nice, like the whole apparatus, but we recall that this is exactly a professional tool and the appearance here has the last meaning. As for the evaluation in our rating, it was deliberately understated, but not because of the quality of the car, but its cost. In everyday life, such a device is simply not needed, and it can only interest people who are professionally involved in welding.

4 Caliber

Most of the welding machines presented on AliExpress have the same drawbacks. In particular, these are short cables, and the absence of the necessary elements in the package, which subsequently have to be bought separately. And here we have the best machine, with the highest configuration. Everything is here, from a small hammer for churning scale after welding, to a shield-type mask. In addition, this is a combined machine that can work both with the electrode and with the wind, and for both directions there is everything you need.

And another very important factor that buyers often pay attention to is the length of the cables. In most cases, it is not sufficient for comfortable work, but here we get the maximum that can only be. For example, the length of the electrode holder and the wire feed hose is five meters.The mass is 3 meters, and this is a lot, and allows you to work quietly without moving the device from place to place. Although this is not a problem, since the device is as compact and lightweight as possible, even though it has a combined structure. And of course the price. It is easy to compare it with an inverter and a semiautomatic device separately and understand that the purchase of two tools will cost much more.

3 LZHZXY

Welding metals is a complex process, and each brand requires its own approach and equipment. For example, ferrous metals are welded by electrodes, aluminum and copper with carbon dioxide, and stainless steel with argon. And these are all completely different devices, but if you do not have the desire or the ability to buy them all, and there is a need for them, we strongly recommend that you pay attention to this car.

Before us is the best combined welding machine that works with both electrodes and wire in an argon environment. You can use it for any purpose, and in addition to everything else it is also a plasma cutter. Yes, yes, exactly, three functions at once in one device and a compact package. And considering this fact, the price, which initially could scare away some readers, no longer seems so high. It is easy to calculate that the purchase of three devices separately will cost much more, and they will take up a lot of space. Here you get everything at once, and in the most compact form factor.

2 K-guard

Semi-automatic, carbon-dioxide welding machines appeared a long time ago, but the compact form, which modern users are accustomed to, has acquired relatively recently. Now this is not bulky equipment that is difficult to move, but a small, convenient tool that does not take up much space in the garage or storage room. Before us is the smallest device that we managed to find on AliExpress. Its dimensions are comparable to a conventional arc inverter, and all thanks to the successful layout of parts inside the case.

But this is not the only advantage. It should also be noted the convenient location of the camera for the wire, which is located in the side. The cassette is changed in one motion, and filling the wire takes a couple of minutes on the force. This unit can be installed either permanently or worn on the shoulder during operation. This is especially important given that almost all machines of this kind have very short cables. You either need to increase them, or constantly move the device behind you. But in this case, you completely get rid of this problem, and the protective cover on the regulators will not allow you to accidentally knock down the settings during operation.

1 REBOOT

It is believed that the semi-automatic inverter can not be cheap. Allegedly, it is a complex tool with many details, but this manufacturer, widely represented on AliExpress, completely refutes this theory. Only 14 thousand rubles for a full-fledged welding machine operating in a carbon dioxide environment. Yes, there is nothing supernatural. In fact, this is an ordinary inverter, but it has everything necessary for high-quality welding.

As for the shortcomings, here they are standard for such tools. For example, short cables. Both the mass and the main holder are only 2 meters, which is not very convenient. However, the device is as light and compact as possible, so there will be no problems in carrying it. It is also necessary to say a few words about the reviews. They are mostly positive and concern both the machine itself and the seller, who very quickly reacts to the order and sends it in the coming days after registration.Simply put, if you are looking for a simple and inexpensive device, then this model is especially for you, and at the most attractive price.
