Welding is a complex, labor-intensive process. Therefore, even when choosing a household welding machine for your home, you need to take into account many parameters:
- Type of power supply: it is preferable to choose models operating from a standard 220 V network.
- What materials are you planning to work with: for cast iron and copper - you need a device with a current rectifier; for ferrous metal - a simple model is suitable.
- The thickness of the metal being welded is directly related to the strength and power of the current.

What is the difference between an inverter and a transformer unit?
If you need to compare whether it is better to work with an inverter or transformer welding machine, you need to understand how difficult one or another welding procedure is, which is more in demand, since both equipment has additional capabilities.

The modernized operating mode greatly simplifies the process.
An inverter semi-automatic or transformer is suitable for welding aluminum, stainless steel and other materials with a complex structure. The inverter makes the process easy and fast. It is also easy to transport, care for, and store, since it does not require certain operating conditions.
The transformer apparatus has almost the same characteristics, but the difference lies in the reliability of the seam resulting in a more economical option. The transformer consumes a lot of energy, which makes the inverter more attractive.
For a variety of continuous welding applications, a transformer will be the best option, but it can only handle simple types of fastening.
Aurora MINIONE 1800 – a rich set of accessories
The average price is 8,000 rubles.
Specifications
- Mains voltage: 220 V
- Current in MMA mode: 20 - 180 A

- Rated voltage: 63V
- Protection class: IP 21
- Power factor (COS?): 0.73
- Overall dimensions: 320x123x220
- Weight: 5 kg.
The inverter is built on advanced IGBT technology and SMT components. The kit includes a two-meter cable, a ground clamp, an electrode holder, and a case for storage and transportation. The device is successfully used in various fields, including construction, agriculture, and when installing metal structures. But the operating voltage must be at least 160 V.
Advantages:
- “Intelligent” cooling: the fan turns on only if the board components and power elements are heated.
- Arc force: the moment a drop of metal separates from the electrode, the welding current increases.
- Hot start.
- Antistick – automatic reduction of welding current in case of electrode sticking. The welder has time to separate the electrode and continue working.

Which welding machine is better to buy for home?
In the courtyard of a private house or in a country house, you have to work with round and profile pipes, angles and sheet metal. Most often, the cross-section of the walls does not exceed 2-4 mm. On the other hand, you may need to weld a channel with a wall of 6-10 mm. Which welding machine to choose for your home depends on the tasks ahead, which include the thickness of the material being welded and the types of metals. The equipment is divided by type of power source and welding modes. Let's discuss this in order.
Which power source is best to use for home?
There are several types of welding power sources. The quality of the seam and the ability to connect different materials depend on the choice. Let's consider what is most suitable for welding at home.
1. Inverters
They are connected to a 220 V or 380 V network and convert low-frequency alternating current into direct current, and then again into alternating current, but with a high frequency. The output produces a constant voltage. The equipment has compact dimensions and is suitable for welding ferrous metals, cast iron and stainless steel. Models with an AC/DC switch are even designed for aluminum welding.

2. Rectifiers
They can operate from both single-phase and three-phase networks. They lower the volts and increase the amperes using the transformer coils, and at the output they rectify the current to constant. They have large dimensions and are often equipped with wheels for transportation. Easily welds carbon and stainless steel.

3. Transformers
They work on a similar principle as rectifiers, only without the last phase of the cycle. Welding is carried out using alternating current. Ferrous metals are best welded. The dimensions of the equipment depend on the power. There are compact devices for wearing on the shoulder and larger ones for stationary installation.
Welding transformer.
For welding at home or in the country, it is best to choose inverters. They produce direct current, which improves the quality of the seam, and have useful features that make it easier for beginners. The price of the product depends on the manufacturer and the capabilities of the device. A cheaper option would be a small transformer, but it is only suitable for non-critical structures (putting up a fence, welding a loop on a gate). It is better for them not to cook heating and plumbing due to alternating current, which increases the splashes of molten metal.
What type of welding is best for home use?
In addition to the power source, the equipment has different modes designed for different types of welding. Having delved into their capabilities, we can better understand how to choose a welding machine for the home.
1. MMA
The abbreviation refers to manual arc welding with coated electrodes. The metal rod melts and creates a seam, and the electrode coating forms a protective cloud. After hardening, a slag crust is present on the surface. Suitable for welding ferrous metals, cast iron. When replacing electrodes with specialized ones, you will be able to cook stainless steel and aluminum. But the quality of the seams greatly depends on the skill of the user.
The equipment is suitable for welding a house to install a fence, gazebo, greenhouse, or replace a heating pipe. Such models are not expensive.

Recommendations for the use of household inverters
When starting to work with a home appliance, you should adhere to the basic rules and recommendations:
- The size of the electricity consumed depends on the diameter of the electrode. It is important to take this fact into account so as not to burn electrical appliances in the area.
- Each electrode corresponds to a certain minimum current strength. Attempting to reduce the current will result in welding failure.
For each current you need to select the appropriate electrode
- For welding work, it is important to have protective clothing: canvas gloves, a jacket made of rough fabric, a helmet.
When performing welding work, the use of protective clothing is mandatory.

Welding methods: lap, butt, tee and corner
The work of a welder involves several methods of welding parts: overlap, butt, T-joint and corner. The seam is made with an inclined electrode, except for butt welding, when the electrode is held almost straight. When doing fillet welding, it is recommended for a beginner to place the parts to be welded “in a boat” rather than in an L shape; in this case, it is easier to achieve a high-quality seam with well-welded edges.

Preparing the elements to be welded
Before starting welding, the joints between parts must be cleaned of dirt and rust and moisture removed. If the thickness of the part is more than 3 mm, then it is better to chamfer the edges; this will allow for better welding of the elements, which is important, especially for a beginner. We recommend that you do not skimp on time and prepare the parts to be welded well.
