Welding inverter "Tesla": characteristics and reviews

The need for reliable connection of various kinds of metal parts in everyday life arises quite often. Until quite recently, it was almost impossible to purchase a good welding machine at a low cost. Previously, for the connection of metal parts, only the bulky, expensive and power consuming transformers were used. However, relatively recently a fundamentally new type of welding equipment appeared in the market - inverters. Such devices are inexpensive and compact. Very often in the domestic market today you can meet, for example, Tesla inverters.

Who produces

As the suppliers of these devices say, they are produced in the Czech Republic, the oldest company with a 30-year history. Many consumers doubt the reliability of such information and believe that these devices, like many others today, are manufactured in China. But, anyway, according to the official version, the Tesla welding inverter manufactured by the Czech manufacturer specializes in assembling not only this type of equipment, but also other similar equipment, and supplying its products to more than 30 countries.

What are the advantages of the devices

The advantages of the models of this brand include, first of all, the optimal combination of price / quality. In operation, Tesla's inverters, in the opinion of many consumers, are reliable. In addition, they differ in their compactness and rather rich functionality. To the pluses of inverters of this brand, many consumers also include a fairly wide range of models. Also, the advantage of Tesla's devices is not a very high level of energy consumption. To voltage surges, equipment from this manufacturer is practically insensitive. Such problems do not affect the quality of welding. As the manufacturer claims, under reduced voltage these inverters can work in the normal mode.

Disadvantages of the models

The main disadvantage of the Tesla machines is a certain "flabbiness" of their design. This equipment is poorly protected from mechanical shocks. Therefore, you need to handle it carefully. Also, the shortcomings of the devices of this brand include a not very well-considered cooling system. Work with the Tesla inverter should only be in places with good natural ventilation. In the summer, this equipment should be pritenyat when welding.

An indirect disadvantage of this type of equipment is also the fact that in most cases it is semi-professional. Too low-cost household amateur devices this manufacturer does not deliver to the market.

Delivers the company Tesla to the Russian and Ukrainian markets:

• MMA 251;

• MMA 255;

• MMA 275;

• MMA 303;

• MMA 280;

• MMA 277;

• MMA 201;

• MMA 235.

The most popular ones are MMA 277, 303 and 251 models. These are the inverters we'll talk about next.

Model MMA 277

Actually, the marking of the MMA itself, like that of any other inverter, at the Tesla apparatus means that it is intended for manual DC arc welding. Good reviews of the MMA 277 device deserved primarily for the fact that it can work in a fairly large range of voltages. At the dacha it is very convenient to use. This modern device does not react to the voltage drop and does not overload the network.

The power button on this model is located on the rear panel. Among other things, MMA 277 is equipped with forced cooling systems and protection against overheating. The regulator of the welding current value of this inverter 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 lights up in green. When the inverter overheats, the color of the indicator changes to yellow. Even lower on the model there are connectors for connecting welding cables.

Like most other modern welding inverters, Tesla MMA 277 is equipped with anti-sticking electrodes and a "hot start".

Technical characteristics of MMA 277

The main parameters describing this model are listed in the table below.

Customer feedback on the MMA 277 model

Technical characteristics of the welding inverter "Tesla" 277, therefore, is relatively good. There are different opinions about this device on the network. Functionality when accounting for a fairly low cost for this model, as many masters believe, is quite good. The quality of the seam, according to consumers, this inverter gives very good. In the domestic market, these models appeared not so long ago. However, many consumers have had them for several years and are working quite well.

To the pluses of the MMA 277 inverter, many home masters, among other things, include a light weight, the presence of a comfortable handle, as well as the ability to attach a belt. In carrying these devices are quite comfortable.

The drawback of the MMA 277 model, as well as of most other Tesla devices, is that some consumers consider the uncertainty in terms of the manufacturer. On different sorts of specialized forums, users sometimes are not even advised to contact these devices, buying a "cat in a poke". However, on such resources there are also good reviews about these inverters. Many believe that the advantages of the MMA 277 model, like many other Tesla devices, are quite a lot.

Tesla Inverter 303

In addition to manual arc welding, this machine can also be used for semi-automatic or argon-arc welding. The modes of device 303 are two - two- and four-stroke. That is, it is convenient to use it for welding both short and long seams. In TIG mode, this machine can work with any metals, except aluminum and its alloys. The TIG burner, complete with the 303 inverter, is not, unfortunately, supplied. You need to buy it separately.

Included with the unit are:

• Burner for semi-automatic welding (3 m)

• Abicor Binzel charged with wire;

• Cable holder (3 m);

• Network connection cable (2 m);

• Cable weight (2 m).

To work with a flux wire in the machine, you need to change the polarity. The gas connection in the Tesla welding inverter 303 is located on the rear panel. A little lower is the cooler.

Technical specifications of model 303

It is worth this device is more expensive than MMA 277. But at the same time the functional is richer for him. Below in the table the technical characteristics of the Tesla welding inverter 303 are presented.

Inverter "Tesla": reviews and discussions on the model 303

To the pluses of the device 303, home masters refer primarily to its high power. Wire in 1 mm this inverter "Tesla", for example, pulls without problems. Also, many consumers believe that this system is very well implemented system of hot strata. Another plus of this model, like most others from the manufacturer Tesla, is a long warranty period. If the device fails not due to the fault of the owner within 3 years after the purchase, the company undertakes to repair it for free.

The drawback of the 303 model is, first of all, the lack of a digital scoreboard. Also, some Web users note the fact that on the market it is often possible to meet defective devices of this modification.

Model MMA 251

This device has compact dimensions. And therefore it is very convenient to use it at a height or in hard-to-reach places. Model MMA 251 can operate at a voltage in the network of 140 V. All necessary for convenient use of the function in this inverter are present. The weight of the model is only 3.2 kg.

Specifications

Good operating characteristics of the Tesla inverter MMA 251 are determined, of course, primarily by the thoughtfulness of its design. Below is a table with the technical characteristics of this model.

Consumer opinion

Reviews about the model MMA 251 "Tesla" at home masters, as well as about other inverters of this manufacturer, has developed relatively well. Most consumers consider them sufficiently reliable.

Reviews about the service of the company

Break the inverters "Tesla", judging by the reviews, it is quite rare (with the exception, of course, of defective models). However, in case of need to repair the owner of such equipment, you may have to suffer. Reviews about the service of the company "Tesla" on the web are, unfortunately, not too good.

Cost of devices

One of the absolute advantages of the Tesla devices, as already mentioned, is not an especially high price for them. Compared to other European models, these inverters do not really cost too much. For example, the price for the MMA 277 device is only about 6600 - 7000 rubles.

The more powerful Tesla inverters 303 are in the range of 22-25 thousand rubles. The price for small models MMA 251 can be equal, depending on the supplier, 5000-5500 rubles.

What you should know about

The number in the marking of such equipment indicates the welding current. Unfortunately, to welding inverters "Tesla", reviews of which are otherwise pretty good, it's practically not true. Do not advise many consumers to navigate when working and on the numbers displayed on the display. In most cases, the welding current of these inverters is less than the claimed.
