12 best welding semiautomatic devices

Rating of reliability and quality of devices for semi-automatic welding

Buying a welding machine is a good solution for owners of villas and houses, motorists who often repair their own metal structures. The main advantage of the semi-automatic machine is its ease of use and high quality of the seam, which makes MIG / MAG devices increasingly popular. Buy a quality device is not so easy, and the reviews about them vary. Let's try to determine the most important criteria for choosing the best welding machine.

Criterias of choice

  • Maximum current in conjunction with constant switching ratio (PV) determine not only the range of applications of the welding machine, but also its "margin of safety". As for the welding current, for many newbies, the lack of such adjustment on the semiautomatic devices causes some bewilderment - they usually regulate the voltage on the torch. For commonly used wire with a diameter of 0.8-1.0 mm, the voltage is set to 20V, depending on the thickness of the parts, the current does not exceed 120 A. The PV determines the percentage ratio of operating time and cooling time of the welding machine: from two inverters with the same maximum current a device with a PV of 60% will require a break in work faster than a device with a PV of 80%. Since this coefficient increases with a decrease in the welding current, with the same PV, the device whose maximum current is higher without stopping will last longer. For semiautomatic devices, this means that it is necessary to acquire a device with a large maximum current only on the basis of long-term continuous operation: you cannot really realize such a current on a conventional wire.
  • Power apparatus and operating voltage range It is important to consider if it is supposed to be powered from a weak power grid in a garage or in the private sector. The less power consumed by the device, the lower the voltage drops during operation. Accordingly, the lower the threshold of the operating voltage range, the greater the drawdown the device will endure without interruptions.
  • The possibility of changing the polarity required when welding flux wire (usually called "powder"). If for welding under carbon dioxide, reverse polarity is used (on the burner “plus”), then for the flux wire, the polarity is straight (on the burner “minus”). Also on straight polarity work with some grades of conventional wire, doped with alkali metals.
  • Additional modes of operationprovided for in the design of many semi-automatic machines, significantly expand their functionality, although they increase the price. Usually, the semiautomatic devices are complemented by the MMA (manual arc welding) mode - by purchasing such an apparatus, you will be able to cook both thin iron and massive metal structures where the wire does not provide deep penetration.

Before you buy, also determine the most important conditions for using the device, namely:

  • home / cottage power;
  • what metals to be welded;
  • thickness of the metal being welded;
  • required welding quality;
  • dimensions of objects for welding, length of welds;
  • intensity of use of the unit.

Top 12 best welding machines

For obvious reasons, only semiautomatic devices powered by a single-phase 220V network are involved in the rating: three-phase powered appliances are large-sized devices for stationary welding posts, it makes no sense to consider such devices for personal use. In addition, for the same reasons, the upper bar of the price was set.

Best welding semi-automatic middle class

Svarog PRO MIG 200 SYNERGY (N229)
51 250

Of the welding semiautomatic devices considered by us, this one deserves an indisputable leadership in the rating. It allows not only to work with any type of wire (polarity is changed in two hand movements by switching the burner power cable on the front panel), but also to work with stick electrodes (MMA mode) and argon torch (TIG DC mode) at currents up to 200 A. At this at currents up to 160A its PV is 100% - therefore, when operating in semi-automatic mode or welding with electrodes up to 4 mm in diameter, it will not be necessary to make forced pauses to cool the device. For the argon burner there is a mode of ignition by touch (TIG Lift).

Another advantage of the PRO MIG 200 SYNERGY is a perfect arc burning control scheme that changes the characteristics of the device depending on the mode of operation of the device: you can choose between manual setting of semi-automatic mode of operation (mode selector on the front panel in the MIG position) and automatic ("synergistic") regulation according to a given program (4 modes for welding in carbon dioxide and gas mixture). Adjustments of welding current and voltage, wire feed speed and voltage drop settings are set by multifunctional regulators, supplemented with digital indicators.

Operation in argon arc welding mode is possible both in two-stroke mode and four-stroke mode: in 2T mode, the arc is ignited when the button is pressed on the torch and goes out when it is released, in 4T mode, the arc is lit after briefly pressing the button until the next button is pressed. Regulators are used to set the welding current and the time of its fall.

To ensure safety when welding in conditions of high humidity in the MMA mode, the VRD mode (reduction of the no-load voltage) is automatically activated in order to avoid electric shock. In addition, manual adjustment of the arc forcing current is available in the MMA mode.

The manufacturer provides its welding machine with a five-year warranty, which is another plus in the PRO MIG 200 SYNERGY piggy bank. As a result, even despite the highest price, this inverter gets a solid "ten".

Main advantages:
  • Multifunctional and flexible settings.
  • Compact size.
  • Low price.
  • No TIG AC mode for welding light alloys.
  • High price.
10 / 10
I never regretted the money spent. This automatic welding machine is the best - it is like a Swiss knife: reliable, convenient and multifunctional.
AuroraPRO Speedway 200
41 500
If the semiautomatic device is chosen for large volumes of work, it is worth thinking about purchasing a device designed for massive coils - this will significantly reduce the cost of the wire. Usually semi-automatic, designed for 20-pound reels - this is a massive structure on wheeled carts, designed for three-phase power supply network. But there are exceptions: Speedway 200, produced by the Chinese company Riland for the domestic brand Aurora, is not only designed for single-phase power, but also withstands a voltage drop of up to 140 volts. Therefore, owners of car services and small firms engaged in the production of metal structures should pay attention to this device.

The semiautomatic has classic mechanical regulators, the current and voltage of the arc are displayed on digital indicators. In the MIG mode, an apparatus having a PV of 60% at a current of 200A will be able to work almost continuously without interruption with the most common wire diameters, 0.8 and 1.0 mm, and it is also possible to use a wire of 1.2 mm. Available flexible inductance adjustment. In the MMA mode, the main working diameters of the electrodes will be 3 and 4 mm, but the device without problems will be able to cook for a long time and the "five".

Of course, the dimensions of this semi-automatic make it quite a specific product, but this cannot be a reason for downgrading. The result is a well-deserved third place.

Main advantages:
  • Use large wire coils.
  • Powerful pulling mechanism.
  • Ability to work with wire 1.2 mm.
  • Solid dimensions.
9.8 / 10
For my volumes of work (I am a professional welder) this semiautomatic device was perfectly suited. I work for 6-8 hours a day, there are no problems with it.
Svarog ARCTIC MIG 250 Y (J04)
62 630

The device is compact enough for “large-coil” semiautomatic devices and is designed mainly for working with thin-walled parts - its average power is 250 amperes at 60% PV. But, anyway, already with a decrease in current to 200 A, it is able to operate continuously. With an open-circuit voltage of 50 V, it is easily ignited on a contaminated surface, although it is indisputable that cooking with a semiautomatic device over mud is still masochism.

Given that the device is designed for long-term work (and the possibilities of the design itself, and work with 300-millimeter coils to have this), it is nice that they immediately included a heated gearbox in the kit. Provides a smooth adjustment of inductance - the device is well adapted to the welding of different materials.

Compared to a similar model without an Arctic device, the device has become more economical (the current consumption is up to 14 A, not 20), the power factor has increased from 0.7 to 0.85 (and this also reduces the load on the supply network), the dimensions and weight. However, at the same time, the device lost the ability to work with the piece electrode and change the polarity - if we don’t attribute the first to unambiguous shortcomings, still devices of this type are bought specifically for working with wire in large volumes, then the lack of support for fluxed wire can interfere with work. The last drawback, which is worth mentioning is the simplicity of the feeder - it has two rollers, which once again confirms the main orientation to the “tin” when working with thin wire.

Main advantages:
  • 100% PV up to 200 A
  • Smooth inductance adjustment
  • Moderate load on the supply network
  • Comparative compactness
  • Heated gearbox included
  • Not the best choice when working with large diameter wire
  • No polarity reversal
9.7 / 10
AuroraPRO Overman 200
27 500
If the presence of additional welding modes is not critical and the device is purchased exclusively for working with wire, take a closer look at Overman 200. This welding machine, like the whole Overman line, can boast of such features that are not frequent in its price segment: a record low threshold of 140V, and when working with metal of different thickness, you can quickly adjust the current-voltage characteristic with an inductance regulator.

Overman 200 can work with all types of wire, including aluminum. An interesting feature of this family of devices is the separate adjustment of the current and voltage of the arc - usually semi-automatic devices have only a voltage regulator. But there is also its own fly in the ointment: when developing the Overman line, the engineers abandoned the smooth manual adjustment of the wire pulling speed, setting the “quick-slow” two-position switch instead of the knob. Therefore, the total score on the totality of qualities has to be reduced.

Main advantages:
  • Resistance to voltage drops.
  • Flexibility settings.
  • Excellent value for money and quality.
  • Coarse wire feed control.
  • Large dimensions and weight.
9.6 / 10
With such a price - excellent quality. Plus, it works without problems from the garage network, although the voltage we have jumps terribly.
Svarog MIG 200Y (J03)
55 530
Another semi-automatic, designed for large volumes of work and, consequently, the use of massive wire coils. There are no additional welding modes here, as in the Overman 200 - the inverter is designed exclusively for working with wire.

PV 60% at a current of 200 A allows you to work with common nominal diameters of 0.8-1 mm without forced stops. The inverter has three adjustments: voltage and arc current, as well as inductance. There is no regulator of wire feed speed here, in principle, the feed is adjusted automatically by the control electronics itself.

When working in the cold, it is possible to connect the heating of the gearbox: the corresponding 36V socket is connected to the back wall of the device.

Main advantages:
  • Flexible settings.
  • Work with 15-kilogram bays.
  • Lack of wire feed speed adjustment.
  • High price.
9.5 / 10
I got the device in my service, the price for me was not the main thing - reliability was in the first place. I don't need repair time.
Fubag INMIG 200 Plus
36 398
The INMIG series is a multifunctional welding machine for professional use, the “200th” model of them is the youngest in the series. This device, in addition to the now fashionable "synergetic control", boasts a rich set of operating modes:
  • Semi-automatic MIG / MAG mode with software-defined parameters for wire feeding and arc burning - the user specifies the type of material and the diameter of the wire used. The mode of welding with short seams is available. SPOT - automatic, regardless of the position of the button on the torch, stops the wire feed after a specified time. This is convenient when welding structures that do not require tightness of the seam: long joints of frames, body repair and so on.
  • Welding with a MMA stick electrode with a current of up to 170 amps, VRD mode is enabled. The characteristics of arc boosting are smoothly tuned.
  • TIG welding in argon medium can be carried out with a current of up to 200 A. The ignition is accomplished by touching.

Alas, this semiautomatic device cannot be called successful: in addition to low PV values ​​(long continuous operation is possible only with a wire with a diameter of 0.8 mm or two-millimeter electrodes), many users also noted the tendency of the device to fail when there is a sharp drop in voltage. For a welding machine that is positioned as a professional, this is unacceptable - hence the reduced rating.

Main advantages:
  • Multifunctional, flexible settings.
  • Affordable price.
  • Rather sensitive to the conditions of work design.
  • Small PV ratio.
9.4 / 10
The device is worthy, the price is affordable. There is no reason to complain about reliability yet, although it is often written on forums that they break with a weak network. Pah-pah, did not check.

The best low cost welding semiautomatic devices

Elitech IC 220P
25 420
This automatic welding machine is one of the best representatives of the budget segment. Its main advantage is the ability to withstand voltage drops up to 160 volts, while it has a small power consumption - no more than 5.4 kW. Therefore, for use in the garage IP 220P - quite a good choice.

The maximum welding current of this semiautomatic device is 180 A, while the PV reaches 80% due to well-thought-out cooling. Work with wire with a diameter of 1 mm will be quite comfortable.

It should be noted the care of the creators of the semi-automatic ergonomic: voltage regulators and wire feed speeds are located on an inclined panel, they are convenient to use both sitting and standing.

In addition, products under the Elitech brand, despite traditionally Chinese origin, have good reviews about reliability. Afraid of Asian origin in this case is not worth it.

Main advantages:
  • Economical power consumption.
  • Compact size.
  • Affordable price.
  • Minimum settings compared to competitors of the same price.
9.0 / 10
Great helper for the garage master. It does not begin to choke and tear a seam at power surges, the price is quite affordable.
Resanta SAIP-200
21 950
From the line "Resanta" is one of the most common and popular semi-automatic. Its advantages should be attributed to a fairly large current margin - 200A, while PV - 70%.When welding with millimeter wire the device does not overheat.

On the other hand, the price of this semi-automatic may seem overpriced, especially if you take into account not the most positive reviews about the quality of the products of this company. This is especially noticeable on the background of the characteristics of the confidently gaining popularity of AuroraPRO Overman, which at the same price can boast of more flexible settings and superior reliability.

The complete set of the semiautomatic device is also not the best: the standard burner, although it is connected to the standard Euro connector, will be short for many works - its sleeve is only 2 meters long. The most obvious indication of the build quality is that the scales on the front panel are interchanged: the voltage regulator actually controls the pulling speed, and vice versa.

Main advantages:
  • Enough large stock of current.
  • The conspicuous negligence of the manufacturer.
  • Sensitivity to dust.
  • Overcharge.
8.2 / 10
I do not argue, semiautomatic cooks, but that's all. If I had a decent choice, I would have bought a better-made one, that's for sure.
Resanta SAIP-165
17 180
The budget inverter from a reputable manufacturer, compact and convenient to operate. Designed for welding with direct current in the environment of protective gases (carbon dioxide, argon). Perhaps this is the most affordable model in the line of inverter semi-automatic. Alas, it does not shine with its characteristics: at PV of 70% and a maximum current of 160A, its use should be limited to 0.8 mm wire in MIG mode and electrodes not thicker than 3 mm in MMA mode. Reviews of reliability traditionally for this brand are not encouraging.

The semiautomatic device can use both a usual, and flux wire. The polarity reversal mechanism is traditionally made in the form of a switchable power supply for the burner on the front panel.

It cannot be said that the semiautomatic device turned out to be successful: in comparison with the previous series, the updated SAIPA-165 became too flat and high. Instability can play a cruel joke if you need to work near the device (for example, when welding under the bottom of a car raised on a lift) - just hook the case a little so that the semiautomatic device falls on its side. Reliability it is clearly not add. In addition, Resanta still stubbornly refuses to use the standard Euro-connector of the welding torch sleeve - it is not so easy to replace the standard two-meter torch with a longer and higher-quality product. Even the very detachment of the sleeve at Resanty is rather inconvenient - from here, by the way, stories about semi-automatic devices with an “integrated” sleeve went.

Main advantages:
  • Low price.
  • Low reliability.
  • Inconvenient and impractical connection of the sleeve.
  • The difficulty in obtaining high-quality weld compared to more expensive models.
7.0 / 10
I bought for infrequent use, so I did not want to buy an expensive device. Alas, I miscalculated: at a low voltage in the network, it cooks disgustingly, and has already managed to bring it in for repair.

The best professional welding semiautomatic devices

Telwin MASTERMIG 400
159 300

Simple as a hammer and just as reliable - perhaps the best feature for this semi-automatic. To begin with, he does not have inverter electronics - this is a classic welding rectifier with a massive transformer. A semiautomatic machine weighs more than a centner, even if there is no protective gas cylinder installed on the rear platform, so the wheels on the platform will not be redundant: it is problematic to move the machine other than rolling.

The idling voltage of a semi-automatic machine is more than forty volts, so it ignites the arc well and not along perfectly cleaned metal. Not without reason, such semi-automatic devices can be seen in many car-care centers engaged in “tin” and repairing silencers. The author at the former work, by the way, also had a “Telvin” semiautomatic device, only even more monstrous.

Conveniently, this model is also available with three-phase (which is logical with a maximum welding current of 400 A), and with single-phase power supply - you can choose the one that suits your conditions. But in the case of single-phase power, consider that under such a powerful apparatus the network will have to be prepared decently - it “eats” up to 20 kilowatts.

The pulling mechanism is on four rollers, it copes well with any wire. Coils can be installed up to fifteen kilograms. Work with fluxed wire without shielding gas is supported. The device has two mass terminals - with a maximum reactance for working with aluminum and copper alloys and with a minimum (carbon or low-alloy steel, stainless steel). A spot welding timer is also provided (optional, true).

Main advantages:
  • Extensive customization options
  • Reliable broach
  • Overall "indestructibility" of the structure
  • Very high mass
9.8 / 10
How many cars they have already digested - do not count. It is adjusted precisely, cooks qualitatively.
Aurora SKYWAY 330 Synergic
90 300

Our rating of the best welding semiautomatic devices continues to be the device of the diametrically opposite class - the inverter with digital control. By “indestructibility”, of course, it’s like walking to Paris to Telwin as a transformer, but it’s not to take away its advantages from Aurora: let's start with the presence of a NAKS certificate. In addition, the device can use stick electrodes, the maximum current in the MMA mode is 300 amperes (as well as when operating in semi-automatic mode).

Due to the use of electronics, this welding semi-automatic is noticeably lighter than transformer "colleagues" - just under 60 kg. Installation of coils up to 20 kg is possible. A cylinder of carbon dioxide, argon or a gas mixture is traditionally installed on the rear platform. The power supply of the device is only from a three-phase network, the “appetite” is quite moderate - up to 18 amperes.

The “synergetic” management may seem confusing, but you can get used to it quickly. The device allows you to save in memory and quickly bring up three settings - this is very convenient when several typical tasks are performed at different intervals. The main setting is carried out by a single button and a multifunction regulator — all welding parameters are set alternately, with the exception of the 4T or 2T mode selection: it is “hung” on a separate button, it also turns on VRD in MMA mode. In addition, the device has certain self-diagnostics tools that allow you to report a fault with an indication by the corresponding error code.

Main advantages:
  • Moderate power consumption
  • MMA Mode Support
  • Quick save and recall of three presets
  • Management requires addiction
  • Three phase power only
9.7 / 10
The seams were sent for flaw detection - the quality is excellent, so that this device can work with confidence.
Cedar MIG-250GS
65 900

A relatively inexpensive inverter unit with a NAKS certificate is powered from a single-phase network, so it will be a good choice for small services or workshops that do not have the ability to connect to a 380 V network. Rated power is up to 7.8 kW, but the power factor is too small (0.73 ), the supply line should be prepared more seriously. The three-phase version of GN in this plan is made better (power factor - 0.93).

The welding current in MIG / MAG and MMA modes is up to 250 A at sixty percent PV, so its main purpose is “tin” in semi-automatic mode (and the wire is also supported by a maximum of millimeter diameter, up to 4 mm . In general, the classic use of such devices - a professional semi-automatic does not have to be a high-power “cabinet”, it will simply never be used in many jobs.

Management is convenient, with digital indication of the established modes. There is an inductance setting, switching between two-stroke and four-stroke modes of operation. A quick choice of polarity by reversing the terminal on the front panel is possible.

Main advantages:
  • Convenient management
  • High weld quality, confirmed by the certification of NAKS
  • Single phase power supply
  • Low PV ratio
  • Work with wire only up to 1 mm (with wire 1.2 mm only the three-phase version GN works)
9.3 / 10
A normal semi-automatic welding machine for the tin, the drawdown in the network keeps excellent - neither the supply nor the voltage float.

So, the range of welding equipment today is so large that it allows you to choose the best welding semiautomatic device with the optimal ratio of cost and functions. In compiling the rating, both consumer qualities, price, and prevalence of models were taken into account. For this reason, both professional devices and frankly amateur ones, but popular in retail chains, have fallen into it.

You should not vote when choosing a semi-automatic wallet: we have quite convincingly given an example of how a more expensive device may turn out to be worse than the less well-known, but also cheaper.
