Which welding inverter is the best to use?

Before moving on to the TOP of the best inverter devices, let's look at their varieties by design, principle of operation and scope of use.

Inverter for manual arc welding (MMA)

Principle of operation. Inverters for RDS are made in a single housing and are distinguished by compact dimensions within the range of 30x20x15 cm. Most often they weigh 3-6 kg and are convenient for working at heights or along a long structure. The welder simply hangs the machine on his shoulder and moves with it. Inside the inverter there is a step-down transformer, a circuit board with switches and a diode bridge. Receiving 220 or 380 V alternating current from the network, the equipment increases its frequency hundreds of times and converts it to direct current.

MMA inverters are available with two connectors to which the holder and ground cables are connected. The clip with the value “-” clings to the product. A coated electrode is attached to “+”. Closing the contacts leads to the initiation of an electric arc. The distance between the end of the electrode and the surface of the product must be maintained within 2-5 mm so that the rod does not stick. The filler metal fills the weld pool to form a weld. The electrode coating, when melting, releases a gas that protects the molten metal from the external environment.

In what case is it better to use. Due to their simplicity and compactness, MMA inverters are often used in the country, in the courtyard of a private house and small workshops. But it works slowly (you need to constantly change electrodes, clean the seams from slag crust), so it is suitable for tasks where the final result and efficiency are a priority, rather than manufacturing time (make your own fence, weld a hinge on a gate, make a greenhouse, etc.) .d.).

Inverter for semi-automatic welding (MIG/MAG)

Principle of operation. MIG/MAG inverters are available in a single housing or separate housing with a feed mechanism. The wire wound around the bobbin here plays the role of an electrode, closing the circuit to form an electric arc. But since the additive is supplied continuously from the drum, the seams are long and even, without obvious transitions. The welder operates a torch, inside which current, wire and shielding gas are supplied. The latter can be inert (argon, helium) or with active protection (carbon dioxide). The advantage of MIG inverters is the fast speed of seam execution and high quality of connection. The absence of slag crust does not require subsequent cleaning.

In what case is it better to use. Such equipment is suitable for car body repairs, mass production of barbecues, doors, gates, and containers. But you need to be prepared for additional costs for a gas cylinder.

Inverter for TIG welding

Principle of operation. Inverters for TIG welding are very similar to models for MMA, only they have a built-in gas supply unit and a connector for connecting the torch control connector. Welding is carried out with a non-consumable electrode (usually tungsten with impurities). Thanks to the sharp sharpening and constant arc distance, the seam is narrow and even. The weld pool is protected from the external environment by inert gas (argon, helium) supplied from the nozzle. The joint surface does not require cleaning or machining.

Such inverters can operate on direct or alternating current. In the first case, this makes it possible to weld stainless steel, black steel and cast iron. In the second case, excellent seams are obtained on aluminum and copper.

In what case is it better to use. It is practical to buy a TIG inverter for the manufacture of structures made of stainless steel or non-ferrous metals. This is in demand at large and small enterprises in the chemical and food industries, car services (repairing bumper bars on SUVs, welding cracks in the crankcase, cooling units), and in the production of heated towel rails.

Inverter for argon arc welding.

Universal welding inverters

This category of inverters contains equipment that combines several welding methods. For example, there are devices for working with coated electrodes and feeding wire from a reel (MMA + MIG). The body has separate connectors for connecting a semi-automatic burner and an electrode holder.

Such an inverter is in demand for car repairs or the manufacture of metal structures, where a high welding speed is required, but from time to time you need to cut something with electric welding or put a seam in an inconvenient place (it is inconvenient to crawl with a torch, but a thin electrode can be bent and inserted).

There are also MMA+TIG inverters. They may have a full-fledged connector for connecting an argon torch with a button (pressing the button simultaneously starts the supply of gas and voltage), or the TIG torch is attached only optionally. In the second case, you will need a valve model, where gas is supplied by opening the tap, and to ignite the electrode you need to touch it to the surface. This is less convenient and is suitable for periodic welding of stainless steel. When mass-producing products, you need to buy an inverter with separate connectors and a built-in burner. The presence of MMA welding will allow you to weld ferrous metal 10-20 mm thick if necessary.

How to choose a good model for your home and garden?

The choice of welding machine should be made based on some basic criteria. The characteristics of the unit should optimize its efficiency, reaching the highest level, and also be optimal for use at home or in the country.

• First, the power rating is key. The wider its minimum and maximum boundaries, the greater the range of applications of the inverter. Also, based on these indicators, it is possible to preliminarily determine for which metals of different thicknesses or structures a certain model can be used.
• Secondly, pay attention to the variability of the supplied voltage. The range width helps to navigate the conditions in which the device can be used. Given the small characteristics of this indicator, you should not subject it to excessive loads or use it in unstable conditions - outside the city or directly from the transformer booth. In addition, the incoming voltage indicator will help to understand the level of arc stabilization.
• Thirdly, it is important to find out the duration of the device’s operating cycle when turned on at maximum current. This parameter helps to understand for what period of time it is advisable to maintain the arc without harm to the device, as well as what kind of break the device needs after its maximum output. Along with it, it is important to have a built-in cooling system or overheat protection with automatic interruption.

The mobility of the device together with the factory equipment is also important. The presence of grounding terminals or holders for electrical wires significantly improves the welding process. It is advisable to pay attention to the presence of a carrying belt or built-in handle in order to optimize the work being done, as well as to simplify the carrying and storage of the inverter.

Resanta SAI 190PROF

Another representative of the same brand, the demand for which is not decreasing, but only growing. This is one of the best-selling models in the SAI line. Its performance characteristics are more than sufficient for household equipment, and its relatively low cost makes the installation in demand among different categories of users.

Compact, easy-to-use welding inverter produces pulses with a power of 190 amperes. The main difference, which is highly appreciated by customers, is the ability to perform welding work with a voltage of only 100 volts. It was this technological solution that made it possible to bring the model into the rating category. It is so successful that even the fairly high price for the household segment of 15 thousand rubles did not reduce consumer demand to a critical level.

MMA VRD 200 from Wester

As opposed to the previous model, the VRD 200 is capable of working without “smoke breaks” in a mode of up to 120 amperes of welding current. In other words, the equipment will be of interest to those who have to work long and often. It is worth considering that this rule does not apply to operations with electrodes with a diameter of 5 mm. In this case, you will have to find time for breaks.

The maximum current is 200A. Additional functions include a standard set typical for most devices of this class: anti-sticking, hot start and arc force. In addition, manufacturers have improved the safety of the design. The terminal voltage is reduced to a minimum level in situations where the inverter is connected to the grid but not in use. And only in case of load the voltage increases sharply to operating parameters.

Based on the operational parameters and cost (approximately 11 thousand rubles), the Wester MMA-VRD 200 can be safely classified as an amateur, but quite reliable and functional model.

MMA welding: what is it?

MMA is called manual arc welding with a covered electrode. This is the simplest method that even beginners can do. The power source is connected to the mains, 2 cables of different polarity for supplying current to the materials being connected.

One cable has a clamp at the end, fixed to the workpiece, the second with a holder at the end is used to fix the electrode. During manual arc welding, the thermal energy of an electric arc is used, which occurs when a simple electrical circuit is closed. Under the thermal influence of the arc, the metal melts and a weld pool is formed. At the moment the flow of electric current stops, the metal cools and crystallizes, thus forming a welded joint.

Equipment for MMA is the simplest, does not require any special additional devices, and its purchase is inexpensive. It is only necessary to set the appropriate current value. The equipment includes (in addition to the welder’s equipment and consumables) the device itself with a wire for connecting to the network and two insulated cables of a suitable cross-section - with a ground clamp and an electrode holder.

Budget model FUBAG IR 200

Despite its modest cost (on average about 8 thousand rubles), the inverter “gives out” up to 200 amperes. It is advisable to use it not only for welding, but also for cutting metal workpieces. In work, you can use electrodes with a diameter of up to 5 mm, which makes it possible to perform almost all work on a personal plot or in an apartment. The power unit works well even in conditions of unstable power supply.

Among the additional functionality, users will be able to take advantage of anti-sticking, arc force and hot start. All of them will be useful for both beginners and experienced welders. The equipment's inclusion in the rating list was greatly facilitated by good assembly and high-quality components. There are few disadvantages, but they exist. The most significant is the short period of continuous operation - 4 minutes. After this, you need to let the inverter cool for 6 minutes and you can continue. So the unit is not suitable for commercial use.

Advantages

• Light weight.
• Efficient cooling.
• Good seam quality.
• Powerful welding cables.

Resanta SAI 220 for the dacha

The well-known Latvian brand has long earned a reputation in the domestic market as a manufacturer of affordable and fairly high-quality welding equipment. Let's consider the main advantages and disadvantages of a particular model. The welding inverter SAI 220 is popular among amateurs and novice welders. Low cost (only 8,000 rubles) plus good assembly and good quality components are the main reasons that make the model in demand.

The maximum that the welder provides is 220 amperes. This is enough to use electrodes with a diameter of up to 5 mm, as well as cut metal of medium thickness. Without a break, he can work 7 minutes out of 10, i.e. It runs for 7 minutes and cools down for 3 minutes. And so on through the cycle. However, the model was nicknamed “dacha” for another reason. It works perfectly with unstable voltage in the power supply network and can withstand fluctuations from 160 to 260 volts.

However, buyers have noted a decline in the build quality of inverters in recent years. Another disadvantage is the demanding equipment. It is undesirable to allow it to become waterlogged or overcooled, as this can lead to rapid failure of the components. Despite such significant disadvantages, SAI 220 remains on the list of the most popular welding machines and rightfully takes its place in the compiled rating.

Editor's Choice

Of all the above models, we recommend the entry-level device Resanta SAI-220 for private use in a country house or country house. It is one of the recognized leaders in its niche and, according to statistics, is one of the most frequently purchased inverters.

From the middle price range, our choice fell on the Resanta SAI-250K device, which has all the advantages of its predecessors, but offers expanded capabilities.

And finally, professional devices. Here Telwin Technology TIG230DC HF/LIFT+AC comes out on top with consistent build quality and an optimal balance between quality and user performance.
