The use of heat created by electric arc to join metallic elements has a long enough history for the welding machine to be a device well known by those passionate about construction, renovation, repair, interior design, etc. Find out in this article what are the reasons to choose an inverter version at the expense of a classic device, for home or business.
Welding machines are used especially in production sectors that include metal parts, on construction sites, but also in the household, being necessary for some repairs that involve gluing. If you have come to the conclusion that you need such a technical solution, we recommend that you consider an inverter type variant and we detail below some important reasons that turn such an acquisition into an advantageous investment.
Compact design with small dimensions
Unlike the classic models of welding machines, which are a bit more voluminous and heavier, the alternative with an inverter has the appearance of a bag, being easy to place in small workshops or in the personal garage. In some cases it can be up to half the size of a traditional transformer variant.
They are also easy to transport, having a low weight, being ideal for craftsmen who do repair work at the client’s premises or for any type of project that involves frequent changes of the area of use.
The innovative technology used to produce these models of welding machines therefore offers you the possibility to have in the household a high-performance and efficient equipment, very easy to fit among the rest of the tools (soldering guns, drill, etc.).

Because inverter models use semiconductor power supplies, they allow more accurate current management and ensure greater electric arc stability. The result is a much better accuracy of operations, whether we are talking about using the heat generated for melting or to facilitate the sectioning of a metal layer.
The same feature allows, in addition, the approach of a variety of metals, such as aluminum and cast iron, and the easy processing of sheet metal with reduced thickness, for example 1mm, which with a classic model would simply be drilled. In traditional versions, the current is managed manually, with a much lower accuracy.
Includes cooling system
Inverter variants are provided from the construction with a fan that ensures the reduction of heat inside, during operation, extending the life of the product and offering a better quality of metal processing. Even if you have to invest a little more than in a classic version, you can be sure that you will have enough time to enjoy the advantages of such a device.
Also, most are provided with a protection circuit that prevents excessive current input, overheating or periods of voltage too high or below the optimum level.
Lower energy consumption
In the case of standard variants, it does not work with a stable current, the electric arc requiring re-ignition about 100-120 times per second, which means that it takes longer to get the same results as an inverter model.
As a guide, we can tell you that a traditional welding machine offers you a power efficiency of about 40-60%, while using an inverter alternative you get a level of 82 to 93%, so almost double in some cases. This is why, both for domestic use and for commercial or industrial use, the latter offer better productivity and lower operating costs.
The presence of ferrite cores in the power transformer, which reduce current losses, contributes to a better efficiency in terms of constructive efficiency. Also, the spools have smaller dimensions, which means less wire and again, smaller losses on the route.
Many models use copper conductor, which has a better electrical conductivity than the aluminum alternative used in the classic versions. The small size also contributes to the energy saving, which materializes both in shorter connection cables between components, and in a smaller fan, which therefore consumes less to ensure the cooling of the interior.
Possibility of analysis and improvement of the welding process
Some of the newer variants of welding inverters include software that records raw data during use, storing it in memory so that it can be analyzed later and improve efficiency where possible. The same software allows the precise modification of most of the parameters that influence the welding process (length of the electric arc, the speed with which the wire advances, etc.).
You can use them to weld with electrodes (MMA), if you are going to use the device on wrought iron and you do not necessarily need a fine operation. It also offers the TIG version, in a gaseous environment, an ideal approach for those who plan to use the device especially to create ornamental objects and need a tool that allows them to work easily on details.
For car projects, so specialized workshops or personal garage, the MIG working version, with wire, is usually used, which combines a high productivity with the possibility to create sutures with a pleasant appearance.
It is also good to know that in terms of electrodes, inverter models can use both basic and rutile or cellulosic variants. This variety makes such a device easy to adapt both to projects that require joints with increased strength and durability, and for those that must take into account the final image.
Suitable for home use
The construction model and the low energy consumption make it possible for these variants of welding devices to be powered without difficulty using the household electrical network, so at 220 – 230V. This feature makes them the best solution for those who want to be able to make joints of metal elements in their own household, without resorting to the services of a craftsman.
