Welding allows you to firmly connect different types of metals. For its implementation, several types of power sources have been developed. There are welding methods: TIG, MMA, MIG / MAG. In this review, we will give tips on choosing equipment depending on the nature of the work and consider the rating of welding machines, compiled taking into account reviews and key parameters. This will help determine the type of machine for welding and choose a model with suitable characteristics.
The selection of goods was carried out on the basis of reviews, opinions and ratings of users posted on various resources on the Internet. All information is taken from public sources. We do not cooperate with manufacturers and trademarks and do not call for the purchase of certain products. The article is for informational purposes only.
Which welding machine is better to choose
Which welding machine is best depends on the amount of work ahead, future operating conditions, the thickness and type of steel to be welded. Consider the types of equipment by type and ability, which will help narrow down the search for goods.
How to determine the type of power source of the welding machine
The main role in the process of welding metals is played by the source that generates the welding current. The characteristics of the CVC and the ability to connect certain types of steel depend on this.
Inverter
A new generation of welding machines based on transistors. The equipment absorbs alternating voltage with a classical frequency of 50-60 Hz, converts it through a diode bridge into direct current, then returns it again to alternating, but with an increased frequency of 100 kHz. Then the amplitude of the volt decreases to 50-80 to create a safe voltage, and the amperes, on the contrary, increase to 140-400. At the last stage, the current becomes constant again.
Such equipment can be domestic and professional. It is connected to the network both 220 and 380 V. The range of current strength allows you to weld a thickness from 1.0 to 20.0 mm (depends on the maximum ampere rating). Constant tension provides even, smooth joints with increased strength. Due to the transistor conversion technology, inverters stand out for their low weight and dimensions. Devices for manual arc welding, argon or semiautomatic devices can operate on the basis of the inverter. Devices with AC / DC mode are suitable for welding aluminum.

Currently, at home, it is advisable to use these types of power sources.
Rectifier
The equipment was named for its function - rectification of current from alternating to constant. For this, coils and diode bridges are used. Unlike inverters, there is no increase in frequency. The absence of transistors affected the increased dimensions of the models. They are connected mainly to 380 V. The devices are more suitable for industries and enterprises. Direct current allows you to perfectly weld both ferrous metals and stainless steel. Most often, rectifiers are used for manual arc welding.

Transformer
The transformer simply lowers the volts to a safe value (50-70 V), and raises the amperes to melt the edges of the metal.This is due to the presence of two windings operating on the principle of magnetic induction. But the technology is distinguished by the large size of the equipment. Transformers are cooked only on alternating current, therefore they are suitable for non-critical structures. There are domestic and industrial models. Used only for manual arc welding.

How to determine the type of welding machine
As we have already indicated above, several types of welding machines are created on the basis of the inverter, which are capable of performing different processes. Which type to give preference depends on the upcoming welding tasks.
MMA welding machines - manual arc welding
Such equipment will only weld ferrous metals. Welding is carried out by the holder and a coated consumable electrode. Seams need to be cleaned from slag, and a constantly burning electrode must be brought to the surface (to maintain an arc length of 3-5 mm) and changed after completion.
Scheme of the manual arc welding process.
The equipment stands out at an affordable price. MMA devices are suitable for a summer residence, a garage, a small workshop, where only low-carbon steel is welded.

MIG / MAG welding machines - semi-automatic shielded gas welding
By this name is meant equipment for semi-automatic welding in a gas environment. The letter I means the use of an inert gas, and the letter A means active. In practice, it is argon or carbon dioxide, less often helium is used. Gas protects the weld pool from the influence of ambient air (prevents the appearance of pores). Semi-automatic welding contains a special mechanism for feeding wire to the torch. The welder only needs to press the button and lead the seam. At the same time, gas purging is started. Seams do not need to be cleaned, the connection is strong and can be uninterrupted.
Scheme of the process of semi-automatic welding.
Semi-automatic welding is advantageous for its high speed of work and an aesthetic appearance of joints. But the equipment is more expensive than devices for MMA. Such models are actively used in car body repair and at various enterprises. Depending on the type of wire installed, ferrous metals, stainless steel and even aluminum can be welded.

TIG welding machines
Method means welding in an argon atmosphere, where an arc burns between the product and a non-consumable tungsten electrode. The latter does not change the length, which means the arc burns steadily and it is easier for the welder to control it. The seam is not covered with slag and does not need subsequent cleaning. With the help of TIG machines, carbon and stainless steel, copper, aluminum and other metals can be welded.
Scheme of the argon arc welding process.
There are industrial and domestic installations. The devices are suitable where thin, but durable seams are needed (manufacturing of towel dryers, collectors, filters for industrial water treatment, in the food and chemical industries). For welding, a cylinder with argon or helium, as well as a gearbox, will be required.
Universal welding machines
Universal welding machines have been developed that combine several or all of the above modes at once. If you need to alternate welding for a building site (channel, corners) with periodic body repair, then it is practical to buy a MMA + MIG welding machine. When there is a need to periodically weld aluminum (engine block, oil pan), then select an inverter with MMA + TIG modes. To make your device ready for any tasks, buy MMA + MIG + TIG.

The manufacturer gives a guarantee for a model of 5 years. According to welders, these inverters rarely break. All declared functions work.
Wert SWI 190
Another easy-to-configure universal welding machine. The inverter supports two modes with a current strength of 20-190 A. It can be connected to a network of 140-250 V. It produces only direct current, therefore it is suitable for welding stainless steel and ferrous metals. PV is 60%. Idling 68 V provides a smooth ignition of the arc. Case dimensions - 25х10х15 cm.
+ Pros of Wert SWI 190
- Steel body.
- The controls are "recessed" inward so as not to stray from an accidental touch.
- Useful features for beginners.
