When choosing reliable equipment for this article and for you, we took into account its efficiency, versatility, functionality, ease of use, safety, and other similar parameters.
Aurora INTER TIG 200 AC/DC Pulse
So, here is a very functional device, proudly bearing the mark of the NAKS certification. The operation of piece electrodes and welding in a protective gas environment is supported, the maximum current output by the inverter converter in both modes is 200 amps.
In Pulse mode, the welder can adjust both the frequency, balance, and lower level of the ripple current, in TIG mode, as you have already understood, both AC and DC welding is available.
At the same time, you can adjust the starting current separately from the working current, adjust the balance in the TIG AC mode, switch between two-stroke and four-stroke modes, and in the latter you can also adjust the crater welding.
In short, it is an excellent welding machine for versatility, capable of working in a variety of conditions-from jewelry welding of thin-walled parts with argon to cutting metal with an electrode.
- the richness of the settings
- solid dimensions and weight
- Torus 200c Super
The Torus brand is well-known among professional welders – inverters of this Moscow company easily survive the warranty period even with the most severe operation, without presenting unpleasant “surprises” even after the end of the warranty.
The MMA / TIG inverter “200c Super” will allow the owner to work at a current of up to 200 A at a PV of 100 – and this means the possibility of full-fledged long-term work with electrodes up to 5 mm in diameter.
It is important that this inverter can have the NAKS certification (this option will be more expensive than the non-certified one by an average of 2 thousand), which is the best proof of the high quality of the welding seams created by the device.
The merit of this is in the microprocessor scheme for forming the current curve – this ensures not only its optimal shape, but also the stability of the characteristics in case of a strong voltage drop.
The inverter will be equally convenient for both a welder with many years of experience and a beginner – it is extremely easy to ignite and hold the arc on it, and in TIG mode in the same way as when welding with a piece electrode.
The minimum current is 20A, which makes it possible to use the “200c Super” inverter for argon welding of the thinnest parts.
- easy to use
- unlimited duration of continuous operation
- operation with voltage drawdowns up to 165 V
- as with all other brands, NAKS certification requires a surcharge
Svarog TECH ARC 205 B (Z203)
This inverter in the MMA and TIG modes, allows you to use a welding current of up to 200 A, while the PV reaches 80%.
At currents of less than 160 A, the efficient cooling system allows the use of the inverter without the obligatory cooling pauses.
When working with the Tech Arc 205 B device, it is worth considering that the power consumed by it in the MMA mode reaches 9 kW, and large drawdowns of the supply voltage are possible.
However, thanks to the built-in digital indicator of the welding current, they can be compensated to a certain extent – on devices where the current is set on the scale of the controller, the current adjustment to the desired value has to be carried out” by eye”.
If you are wondering which professional welding machine is better, then we can say with confidence-Svarog TECH ARC 205 B (Z203)!
- possibility of long-term operation
- easy arc ignition in both welding modes
- convenient current adjustment
- the inability to weld aluminum
Quattro Elementi MultiPro 2100
This welding machine has almost the maximum possible versatility: the “Italian” is able to work both as a semi-automatic machine and cook in MMA and TIG modes.
Of course, with a maximum current of 160 A and a low PV, it is not considered professional, but in a personal workshop, its capabilities will be sufficient.
Taking into account the fact that the afterburner of the arc, anti-sticking, and “hot start” are introduced into the design of the device, it is difficult to demand anything else for the MMA mode if you work with electrodes with a diameter of 2-3 mm.
Do you need to cook a fine iron? Well, put the coil with the wire and connect the burner. In MIG-mode, the device is able to work on a two-stroke or four-stroke circuit, although this is not attributed to such serious advantages – it would be better if the manufacturer expanded the TIG mode settings.
- combining MMA, MIG, TIG DC welding
- ease of operation
- digital display
- limited power
- limited transportability
Fast and Furious-161
The welding inverter produced by the Ryazan Instrument Plant, although it does not shock with the declared characteristics or ultra-modern design, will give the professional exactly what he needs-reliability and accuracy of forming the current-voltage characteristics of the welding current in MMA and TIG modes.
In both cases, the maximum welding current is 160A, but the continuous operation is possible at a current of no more than 100 A.
Therefore, this inverter is most suitable for working with a fairly thin metal that does not require deep welding at a high current.
The advantages of the device include the ability to work with strong voltage drawdowns-the manufacturer’s stated performance at 140V in the socket is perfectly confirmed in practice.
The “soft” arc is easily ignited and burns without much metal splashing. The automatic control of the fan applied in the inverter by a signal from the temperature sensor significantly reduces the amount of dust sucked into the housing, respectively, making the need for cleaning the radiators of the output stage rarer.
- stable performance in case of voltage drawdowns
- high reliability
- automatic activation of “anti-jamming” is convenient for novice welders
- thereare no wires in the kit
The most versatile device in the review-it allows its owner to work with both welding wire in MIG/MAG mode, and with piece electrodes and an argon burner (although only in TIG DC mode – it will not be possible to use it for welding aluminum alloys).
This inverter belongs to the family of welding machines with microprocessor synergetic control: it has only two controls – a touch-sensitive mode selection button and a multi-function controller.
Most gorenje arc parameters are set automatically depending on the selected mode. This is convenient for beginners, but a professional welder is more likely to choose a device with a large number of manual settings.
In addition, full operation at high currents and low limit value PV: the long cooking electrode is possible only when the diameter up to 3 mm, which given the high price of the inverter led to a noticeable downgrade in the rating of the best welding machines.
- convenient for beginners multi-
- focus on low currents
- sensitivity to voltage draw downs
BLUE WELD Prestige 186 PRO
This “universal”, designed for MMA and TIG welding, is quite simple (but cheap for this class): primary it mode stick electrodes, working under argon due to the low settings is not always convenient.
So we have a welding machine rather for “garage craftsmen”, either only mastering argon in addition to working with the already familiar electrodes, or needing TIG welding on a case-by-case basis and without high requirements for the quality of the seam.
The inverter is compact and quite light, which is again a plus for the garage – there is usually no extra space.
It tolerates voltage draw downs quite well, although at low power this is not surprising: the welder consumes only 4 kW, developing an output current of up to 160 A at a PV of 60%.
- build quality
- easy ignition and operation
- limited TIG welding capabilities
FUBAG IR 200
This welding inverter boasts not only a high maximum current of 200 amps, which allows it to be used for welding and cutting metal with all types of electrodes with a diameter of up to 5 millimeters but also a wide range of operating voltages.
The efficiency of the welding machine is maintained when the voltage in the socket drops to 150 V, which will be appreciated by garage owners and residents of rural areas.
To facilitate the work, the functions of anti-sticking, arc afterburner, and hot start are provided, so that even a beginner can work effectively with the IR 200.
Wait. We are looking for the best deals!
- a decent supply current
- performance for large drawdowns voltage
- to facilitate the ignition and maintaining arc modes
- insufficient duration of continuous operation
Wmaster MMA-VRD 200
This compact welding inverter is very attractive in its characteristics: with a maximum welding current of 200 A.
Continuous operation is already possible at 126 A, that is, in most cases, it will not require breaks for cooling.
You don’t constantly cook massive structures with five-millimeter electrodes, do you? All the functions that a modern inverter is supposed to have for MMA welding are also present here – “anti-sticking”, “hot start”, and arc afterburner.
Since the no-load voltage here is 65 V, for the safety of operation in high humidity, the manufacturer has introduced a VRD circuit into the circuit, which automatically reduces the voltage at the terminals when welding is not carried out, but the device is not switched off.
Wait. We are looking for the best deals!
- possibility of continuous operation at currents up to 126 A
- short standard wires
ELITECH AIS 200
Although the marking of this welding inverter leads to the idea that the maximum welding current here is 200 amps.
In fact, the reality is a little more modest: it can “squeeze” out of itself only 180 A, and at a PV of only 60%.
Thus, the best choice for him is welding with 2-3 mm electrodes, with the “four” already planned smoke breaks will be required, if you do not try to test the safety margin of the welder in practice.
As for the safety margin, here this term can be understood almost literally: compared to many representatives of its class, Elitech will seem like a real “brick”, because it weighs 8 kg – one and a half times more than many inverters with the same maximum current.
The scheme in it quite satisfies modern ideas about the welding inverter: the afterburner of the arc is provided, the current consumption is quite acceptable.
Wait. We are looking for the best deals!
- reliability high
- quality cables included the
- presence of arc forcing
- large weight
- large dimensions
- the relatively low value of the PV coefficient
Best Professional Inverter welding machine
At the moment, in 2020, the most purchased model and the best according to reviews is the model – BLUEWELD Starmig 210 Dual Synergic.
If we abstract from the price, which is not exactly called democratic here, then this semi-automatic machine is very interesting.
Already purely externally, it stands out from a number of its own kind with a large liquid crystal screen, which is very, very informative.
However, the main thing here is not the appearance, but the “filling”: the brand term “synergetic control” means a completely software-based adjustment of the characteristics of the welding machine, selected for a specific function.
Even the welding current can be calculated by the machine itself, based on the thickness of the parts to be welded and the type of wire.
If you are such a brutal welder that all these “whistles” are not needed at all, then you can turn off the synergetic mode completely and turn the adjustments the old-fashioned way.
So the impression of this semi-automatic, of course, is controversial. On the one hand, for a novice welder, it will be a real discovery, allowing you to master various methods of semi-automatic welding with maximum ease.
But, on the other hand, not every self-taught welder can afford to fork out a considerable amount, which is enough for two good welders. Definitely, we recommend you to buy it!
And this is where our article comes to an end. We hope that we have provided you with enough information to make the right purchase. Good luck!
