Build a gate or a small fence, weld a leaking pipe, patch up your favorite “swallow” or do gardening and building a greenhouse - all this can be done independently with the help of skillful hands, pieces of metal and welding machine. Now you do not need to contact specialists, spend extra money for 5 minutes of work. It will be much cheaper to figure it out on your own, having previously bought inverter welding.

But how to choose such a device so that it would not be a shame to work, and it lasted for 2 years for sure? We will tell you about this in the framework of this article, and we will also present the 10 best welding inverters for everyday use at home.

Top welding inverters - how the unit works

Inverters have dramatically replaced competing transformer models in recent years. The first ones are lighter and more reliable, they fold compactly, and learning to “cook” on such equipment is many times easier, so they are chosen for living conditions.

To intermarry with a new apparatus, it is important to know the principles of its operation. The name itself already speaks about how the machine will work. The process uses the inverter principle: electricity passes through several nodes, along which the result is displayed in the form of a melting spark. The current conversion stages look like this:

  • the usual 220 V (in more powerful models there are also 380 V) are converted from alternating diodes to direct current;
  • the constant further through the transistors becomes variable back, increasing the frequency (up to 50 and even 100 kHz);
  • then the current decreases to 70-90 V, and therefore its strength increases (according to Ohm's law) to 200 amperes or more;
  •  high frequency voltage is equalized.

Additional energy conversion allows you to install miniature transistors in the device, which is how it differs from a standard transformer.

What are the advantages of using inverter type welding

The principle underlying the operation of the equipment made it possible to highlight the main advantages of the devices included in the rating of inverter welding machines:

  • small size and light weight (up to 10 kg);
  • easy to manage and configure;
  • even with minimal knowledge and skills, the “teapot” can immediately get a fairly even welding line;
  • the ability to adjust the current strength to work with various metals, you can insert several types of electrodes;
  • economical in terms of energy consumption;
  • stable operation without power drops;
  • almost all devices have built-in automatic shutdown functions and a protective block against short circuits;
  • many functions allow you to improve the quality and performance of welding several times; knowledge of how to use the device is required to a minimum.

Before moving on to the rating of welding inverters, let's talk about what criteria you should rely on when choosing a particular model:

  1. Almost all devices are equipped with built-in protection against current surges. The average level of security is 20-25%. Large industrial appliances have such an indicator; for household appliances, a ratio of up to 15% will be enough.
  2. Ventilation system. It is very bad when there is a lot of dust in the working area - the inverter sucks in all the surrounding dirt. You simply cannot do without a cooling fan. There are 2 options here: either you have a lot of money to allow professional industrial design welding, or remove the lid and wipe the instrument regularly, otherwise its shelf life will be halved, or even more.
  3. An interesting point: if there is a circuit board service nearby, then ask if there are circuit boards for the machine you have chosen. If so, the possible repair will be quick and inexpensive. In other cases, the board simply will not be found or it will be very expensive to print - it's easier to buy a new one.
  4. temperature mode of operation. With positive indicators, everything is simple: the larger the mark, the faster the welding protection will react. But the use of negative indicators is an unpleasant topic. The device is a combination of transistors and other parts that operate at different temperatures to the maximum. And in the assembly, the temperature will generally be different. It is better to refrain from working during frosts, and in addition, you can find a tool passport on the Internet and see its temperature regime.
  5. Do not be afraid of the name "household". This does not mean that it is very weak or that its parameters are enough for one or two seams. Everything is radically opposite: if the manufacturer indicates “professional”, this does not mean that he is. Many under this tag sell models for the home user, but the price will jump by 2 or even 3 times. Think before you buy!

Top welding inverters for home

Our rating of inverter-type welding machines includes only those models that users have noted positively on the websites of popular online stores or in reviews. If you have a different opinion - we are happy to wait for your thoughts in the comments!

WESTER IWT200. Our rating of household welding inverters opens with an excellent device for a beginner in this field. The mass of the device is only 5 kg. The peculiarity of this device is that the manufacturer has installed all the "chips" of a professional equipment: overheating protection, electricity saving, work simplification system and automatic cooling. The average price for an inverter starts from 9 thousand rubles. rubles.

RESANTA SAI 190PROF. The key "highlight" of this welding is that even at a voltage of 100 volts, it can keep an even arc. The only negative is that you can install diodes no more than 5 mm. When welding metal, the device does not spray the arc, which saves energy and firmly seals the layer of stainless steel or copper. You can buy a device from 14 thousand rubles. rubles.

MARS MMA 2000. This tool has replenished our rating of inverter welding machines for the home, which will help its user save money. Efficiency is about 85%, while using low energy consumption technologies that do not reduce power. The case is equipped with anti-static protection for the safety of the master. And the attractive price adds pluses - only 7 thousand rubles. rubles.

GerrardMMA-200. One of the most budget. It will satisfy the needs of any master, because the welding range is from 20 to 200 amperes. This is enough for any homework with metal up to 5 mm. The price varies within 6500 rubles.

KEDR MMA-200. Another device that has replenished the rating of inexpensive welding inverters. Differs in the profitability and comfortable use; efficiency level is about 85%. Welding range - from 20 to 200 A. KEDR is perfectly repaired, and it is easy to find spare parts for it. The price of the product is about 5400 rubles.

Kaiser NBC-200. The weight of the device is slightly more than competitors - 6.5 kg. But the power is an order of magnitude higher - 8 kW with standard 4-5. Plus - the use of an overheating protection system. With skill and a little experience, you can achieve professional seams. The cost of the tool does not exceed 5 thousand rubles. rubles.

WMaster MMA-291. Known for its reliability, albeit quite powerful for home use. The maximum cooking power is 290 amperes. Additionally, there is an arc stabilization function. You will not find a similar device, and even for 13,500.

SP-2500 PROFI NEW. Universal model of premium class. Power - 7 kW, power - up to 250 A. The device is simply crammed with additional functions: current regulation, arc alignment, quick start, overheat protection. The average price is about 20 thousand rubles. rubles.

SHYUAN MMA-630A. This is a tool only for those who really want and can afford it. They can both cook and melt, cut any non-ferrous metal. Works in any environment, delivering a maximum force of about 360 A. Weight - 48 kg, and the price is 57,500 rubles.

Models from Fubag are German-made equipment that allows even inexperienced craftsmen to weld. The main advantage is that the devices withstand voltage drops from 130 to 265 volts. The line includes both inexpensive models and industrial designs.
