Officially, the concept of "mini welding machine" does not exist. The equipment is divided only into domestic and professional, as well as intermediate models. But Chinese developers have created a number of compact welding machines, which are gaining more and more popularity. We will discuss where such equipment is applicable, what are its advantages and disadvantages, and also consider the rating of the best models, based on customer reviews and product characteristics. All this will help you navigate a wide range of products and choose a device that will not disappoint.

Pros and cons of compact equipment

By mini welding machines we mean household models with a housing size of about 20 x 20 x 10 cm. They can be constructed on the basis of transistors and cook with direct current (inverters) or in the form of small transformers that produce alternating voltage.

Pros of Mini Welders

1. Compact devices are easier to store and carry

Unlike large inverters, the mini unit will fit in the pantry of the apartment. You can not put it out of the trunk of the car, since it is four times smaller than the spare wheel and its presence does not affect the capacity of the compartment at all. If necessary, the device can be delivered to the place of work even in the hands.

2. Light weight

Mini welding models weigh 2-3 kg. Most often they are equipped with a shoulder strap for wearing. A mass not higher than a laptop allows you to conveniently carry them on your shoulder or work along a long structure and even at a height.

3. Fine adjustment

Although the equipment is compact, the presence of microcircuits allows you to accurately set the current strength and configure the device.

4. Low network load

You can connect a mini welder to a 220 V household outlet and not worry that the wiring in the wall will overheat, since the power consumption of the device is at the level of a good iron or electric kettle. When using the device all day in the yard, the energy consumption will not be large and you will not have to pay a noticeably large amount for electricity.

5. Sufficient amps

Although mini models look like toys, they are real welding machines with a current strength of 100-160 A. This is enough to boil metal with a thickness of 3-8 mm.

6. Quality work

If the user is experienced enough, then with such a device you can get high-quality, sealed seams.

7. Equipped with additional features

Often, manufacturers provide the equipment with additional functions that simplify the excitation of the electric arc and prevent the electrode from sticking.

8. Low cost

The price of mini welding machines is the most affordable in the market in comparison with other household models.

9. Easier to work in the field

Low power consumption allows you to connect mini-devices to gas generators of any class for welding in the field.

Compact equipment has many advantages, but there are a number of disadvantages. You need to be prepared for them and think through everything so that the device can truly work in specific conditions.

Cons of mini welding machines

1. Small diameter electrodes

A mini-welder will only work with electrodes with a diameter of 2 or 3 mm.

2. Cooling problems

The small dimensions of the case led to the fact that inside there is no complete cooling system with several fans and radiators that remove heat. As a result, the welding machine quickly overheats and turns off until it cools down. With a large amount of work, frequent stops will be required, which stretches the time it takes to complete the task.

3. The claimed current range of 100-160 A is not always true

In practice (when measured by the device), the current can reach 80-100 A, which is not enough to boil the workpieces with a thickness of more than 5 mm. It is almost impossible to cut with such equipment (only sheet metal with a cross section of 1-1.5 mm with good mains voltage).

4. Budget equipment

Due to the low cost, goods of this category are sold with short cables of 1.2-1.5 m, often without a rigid handle, without a suitcase. The quality of the holder and the clamping mass is suitable only for rare use, and with frequent use it breaks quickly. Masks, brushes and gaiters in the kit almost never occur.

If the mini-welding machine is equipped with additional accessories, the quality of their performance leaves much to be desired.

5. Difficulty working with voltage reduction

If it is necessary to carry out welding work far from home, then when using an extension cord of 30-50 m, the ampere rating will become even lower. If near the outlet the apparatus could boil steel 5 mm thick, then under such conditions the electrode will simply melt from above, and the arc will not be able to penetrate deep into. With a "drawdown" of the network (holiday village, garage cooperative), the power characteristics of the equipment also fall.

Applications for mini welding machines

Due to affordability, compactness and lightness, mini welding machines are actively used in the household sphere: to weld a fence in the country, make a brazier, bring a water pipe to the garden, weld a crack between the hinge and the goalpost, put a gazebo or greenhouse.

More experienced craftsmen are able to make a container with him for a summer shower or for fuel. It is convenient to work with such models on the shoulder, so installing a long fence or attaching the antenna to the roof does not require the help of assistants - the welder moves with the inverter himself and his hands are free to hold the workpieces.

But this is an exclusively household class of goods designed to work several times a month. For a small workshop or commercial activity, it will not work and will quickly burn from stress. In addition, welding capabilities are limited to a thickness of 3-8 mm and are not suitable for critical structures.

Rating of the best mini welding machines

Having considered the advantages and disadvantages of equipment in general, it will move on to specific products in the ranking. The material was compiled according to the reviews of beginners and experienced welders. The characteristics of the models are taken into account here. All this will simplify the choice and help to purchase an already tested device, and not a "pig in a poke".


In the first place is the rating of a household mini inverter from a German manufacturer. This is the “youngest” welding machine in the IQ line. It is made in an iron case and is equipped with indicators of overheating and network availability. The device is connected to a network with a voltage of 150-270 V and consumes a power of 4.6 kW. Equipped with two wires 1.2 + 1.8 m with a cross section DX25. The current can be adjusted from 20 to 160 A. It is convenient for welders to carry it thanks to a weight of 2.7 kg and a size of 26x10x15 cm. Although it does not have a display, there are three auxiliary functions to improve the quality of the seam.
