The need for a reliable connection of all kindsmetal parts in the domestic environment occurs quite often. More recently, to acquire a good welding machine at a low cost was almost impossible. Previously, only bulky, expensive and transformer devices consuming a lot of electricity were used to connect metal parts. However, relatively recently a fundamentally new type of welding equipment appeared - inverters. These devices are inexpensive and compact. Very often in the domestic market today you can find, for example, Tesla inverters.
Who produces
According to the suppliers of these devices,They are produced in the Czech Republic, the oldest company with a 30-year history. Many consumers doubt the authenticity of such information and believe that these devices, like many others today, are made in China. But, anyway, according to the official version, Tesla welding inverters are manufactured by the Czech manufacturer, specializing in assembling not only devices of this type, but also other similar equipment, and supplying their products to more than 30 countries of the world.
What are the advantages of different devices
The advantages of the models of this brand are primarilyoptimum combination price / quality. In operation, Tesla inverters, in the opinion of many consumers, are reliable. In addition, they are compact and fairly rich in functionality. The advantages of inverters of this brand, many consumers include, and quite a wide range of models. Also the dignity of the devices "Tesla" is considered not too high level of energy consumption. To power surges equipment from this manufacturer is practically insensitive. Such problems do not affect the quality of welding. As the manufacturer claims, at reduced voltage, these inverters can operate normally.
Model flaws
The main disadvantage of the devices "Tesla" is consideredsome "fragility" of their design. This equipment is poorly protected from mechanical shock. Therefore, it is necessary to handle it carefully. Also the disadvantages of devices of this brand include not too thoughtful cooling system. Work with the inverter "Tesla" should only be in places with good natural ventilation. In the summer of this equipment when welding, it is desirable pritenyat.
Indirect lack of equipment of this typeit is also considered that in most cases it is semi-professional. Too cheap household amateur devices, this manufacturer does not supply to the market.
Model range of welding inverters
The company "Tesla" supplies the Russian and Ukrainian markets with devices:
MMA 251;
MMA 255;
MMA 275;
MMA 303;
MMA 280;
MMA 277;
MMA 201;
MMA 235.
The most popular with consumers are models MMA 277, 303 and 251. It is about these inverters and let's talk further.
MMA model 277
Actually the marking itself MMA, like anyanother inverter, the apparatus "Tesla" means that it is designed for manual arc welding with direct current. The MMA 277 device has deserved quite good feedback from consumers, primarily because it can work in a rather large voltage range. At the cottage it is very convenient to use. This modern device does not respond to a drop in voltage and does not overload the network.
The power button on this model is located onback panel. In addition, MMA 277 is equipped with forced cooling systems and protection against overheating. The inverter current controller is located on the front panel. Just below it are indicators of power and overheating. In the event that the current passes through the apparatus, the first light is green. If the inverter overheats, the indicator color changes to yellow. Even lower on the model are connectors for connecting welding cables.
Like most other modern welding inverters, the Tesla MMA 277 is equipped with functions to prevent sticking of the electrodes and hot start.

Power | 3.6 kW |
Welding current | 10-277 A |
Input voltage | 190-240 V |
No-load voltage | 70 V |
Phase | 1 |
Electrode Diameter | 1.6-4 mm |
The weight | 4.7 kg |
Consumer Reviews on MMA Model 277
Specifications of welding inverter"Tesla" 277, thus, has relatively good. Opinions about this device in the network are different. Functionality, taking into account the rather low cost of this model, as many masters believe, is quite good. The quality of the seam, according to consumers, this inverter gives a very good. In the domestic market, these models appeared not so long ago. However, many consumers have them for several years now and are working quite regularly.
The advantages of the inverter MMA 277, many homemasters, among other things, include a small weight, the presence of a convenient handle, and the possibility of attaching a belt. In carrying these devices are quite comfortable.
The disadvantage of the model is MMA 277, like mostother Tesla brand devices, some consumers consider uncertainty in terms of the manufacturer. At various kinds of specialized forums, users sometimes do not even advise contacting these devices, buying a “cat in a bag”. However, on such resources, there are good reviews about these inverters. Many believe that the advantages of the model MMA 277, like many other devices "Tesla", quite a lot.
Inverter "Tesla" 303
In addition to manual arc welding, this unit canused for semi-automatic or argon arc. The modes of the device 303 two - two - and four-stroke. That is, it is convenient to use it for welding both short and long seams. In TIG mode, this device can work with any metals, except aluminum and its alloys. TIG torch complete with inverter 303, unfortunately, is not supplied. You need to buy it separately.
Included with the device are:
torch for semi-automatic welding (3 m)
Abicor Binzel charged wire;
electrode holder cable (3 m);
network connection cable (2 m);
cable mass (2 m).
To work with flux wire in the device, you need to change the polarity. The gas connection in the Tesla welding inverter 303 is located on the rear panel. Below is a cooler.
Specifications Model 303
This device is more expensive than MMA 277. But at the same time, its functionality is richer. The table below shows the technical characteristics of the welding inverter "Tesla" 303.
Parameter | Value |
Power | 5.6 kW |
Welding current | 10-303 A |
Input voltage | 190-240 V |
Phases | 1 |
Wire feed speed | 2.5-12 m / min |
Electrodes | 1.6-4 mm |
Inverter "Tesla": reviews of the model 303
The advantages of the device 303 home masters includefirst of all its high power. Wire 1 mm of this inverter "Tesla", for example, pulls without problems. Also, many consumers believe that this system is very well implemented hot stratum system. Another advantage of this model, like most others from the manufacturer Tesla, is a long warranty period. If the device fails through no fault of the owner within 3 years after the purchase, the company undertakes to repair it for free.
The disadvantage of the model 303 is primarily the lack of a digital scoreboard. Also, some Web users note the fact that in the market one can often find defective devices of this modification.
MMA model 251
This unit has a compact size.And therefore it is very convenient to use at height or in remote places. Model MMA 251 can operate at a voltage of 140 V. All necessary functions for convenient use are present in this inverter. The weight of the model is only 3.2 kg.
Specifications
Good inverter performance"Tesla" MMA 251 is determined, of course, first of all by the reasonableness of its design. Below is a table with the technical characteristics of this model.
Parameter | Value |
Power | 4.8 kW |
Input voltage | 140-220 V |
Current | 10-250 A |

Consumer opinion
Reviews of the model MMA 251 "Tesla" from home craftsmen, as well as other inverters from this manufacturer, has developed relatively well. Most consumers consider them quite reliable.
Feedback on the company's service
Breaking inverters "Tesla", judging by the reviews,quite rarely (except for, of course, defective models). However, if necessary, repair the owner of such technology may have to suffer. Reviews about the service of the company "Tesla" on the web are, unfortunately, not too good.
The cost of devices
One of the undoubted advantages of devices"Tesla", as already mentioned, is not a particularly high price for them. In comparison with other European models, these inverters are actually not too expensive. For example, the price of a MMA 277 device is only about 6,600 - 7,000 rubles.
More powerful inverters "Tesla" 303 are in the range of 22-25 thousand rubles. The price for small models of MMA 251 can be equal, depending on the supplier, 5000-5500 rubles.
What you should know about
The number in the marking of such equipmentdenotes welding current. Unfortunately, the Tesla welding inverters, the reviews about which are otherwise pretty good, are practically not relevant. Many consumers are not advised to focus on the numbers displayed on the display. In most cases, the welding current of these inverters is less than stated.
