Modern welding machines amaze with their variety. There are a large number of types of welding machines on the market, from which each user can choose the best welding machine for effective and safe use.

To do this, you need to know what types of welding machines exist, study their characteristics and the rules for choosing them. Only in this case, you can purchase a suitable device.

How to choose the right welding machine

Types of welding

There are several types of best welding machine brands. Each of them has pros and cons that you need to consider before buying.


The principle of operation of the device is to reduce the input voltage to the level when a stable arc is formed.

Depending on the method of voltage regulation, there are two types of transformers:

With the amplitude method of voltage regulation. Here, the windings are displaced by mechanical action.

With phase control. It is provided by thrusts. This is the most acceptable option for welding machines of this type since it allows you to optimally regulate the current during a particular operation.

The peculiarity of the devices is that the alternating current appears exclusively at the output and in no other way. It is for this reason that the use of the device gives a low quality of material processing.

However, the devices also have advantages, namely:

  1. Easy operation.
  2. High degree of reliability.
  3. Budget price.
  4. High performance.                                                                                                                                                                     

In addition to the poor quality of processing, the following disadvantages of the unit are distinguished:

  • Substantial dimensions and heavy weight.
  • Dependence on the mains voltage –
  • if it decreases, the welding quality deteriorates.
  • Increased power consumption.


These are more modern devices.

The device is equipped with a rectifier unit that converts alternating current into direct current.

This is the main difference from the previous type of welding machine. The tool is characterized by high quality material processing.

Rectifiers have the following advantages:

An additional function of the devices is welding with wire. No electrodes are used here, and no gas protection is required.

The essence of the procedure is the supply of a gas mixture with the simultaneous output of a wire that melts under the influence of an electric arc.

There are the following types of such tools:

  • The device with a forced supply of gas.
  • Devices with the function of switching off the gas supply.

Gas-free devices that operate exclusively with flux electrodes, which provide a protective layer over the welding site during the use of the unit for its intended purpose.

Areas of application of such devices:

  • In industrial enterprises.

  • Advantages:
  • Light weight and compact dimensions.
  • High degree of reliability.
  • Easy to use and maintain.
  • High quality of processing.
  • Expert opinion
  • Such devices are recommended for home use.
  • Semi-automatic machines

These devices differ from the previous version with a higher power. In this regard, they have large dimensions and significant weight.

The essence of the devices is to feed the wire into the welding area using a special device. Such units can recommend for use in production. They are not suitable for home use.

In an inert cloud

This is a kind of semi-automatic, but with a more complex device. Such equipment belongs to professional devices, so it is used mainly in production. It is not suitable for use at home.

Argon arc device

Types of welding

Initially, it can plan that the device would use in industrial production, but the manufacturers decided to introduce devices for use at home.

The design of the devices:

  1. The source of current.
  2. Gas-type gearbox.
  3. The burner.
  4. An oscillator for converting current
  5. into high-frequency pulses
  6. that provide a stable,
  7. smooth, non-contact arc.
  8. Gas cutting and welding equipment
  9. It is these devices that allow you to heat the metal to the melting point.

Such units have the following advantages:

  • The devices work without electricity.
  • Easy to use.


  • High price.
  • Low performance.
  • Poor welding quality.
  • Spot welding equipment

These units can recommend for use for point operations when assembling structures. Here, the two electrodes can locate in the same plane.

They provide instant melting of the metal at the point of contact. At the same time, there is no overheating, scale or roasting.

Types of welding

These are devices that provide a high-precision and high-quality procedure in a short period of time. The devices can be used even for work pieces of large thickness. The only drawback of the unit is the high cost.

Rules for the choice of device

So, when buying transformers, it is recommended to pay attention to the following points:

Operating voltage: For home use, three-phase or single-phase 380/220 V devices are suitable. You can also purchase a universal unit that is suitable for any type of voltage.

Power of the device: It is not necessary to purchase a device of the highest power. The main thing is that the device is suitable for the home network.

Parameters of the operating currents and the size of the electrodes. In this case, it all depends on what material the device will use for.

Dimensions of the unit. The smaller the size, the easier it will be to choose to store the device and transport it.

When choosing rectifiers, it can recommend to focus on such moments:

The presence of a pulse rectifier current. Only in this case, the devices guarantee a stable arc and minimal metal splashing.

In addition, such devices form a high-quality seam and do not require frequent replacement of consumables.

Operating voltage: It should be suitable for the home network.

Principles of adjustment of welding modes: This ensures the convenience of the performed procedure.

Selection criteria for inverter welding machines:

Operating voltage: It should be suitable for the home network.

Characteristics of welding currents and modes: In this case, it all depends on what thickness of the material the device will use for.

The duration of switching on the PV. This indicator will determine how long the device will function at maximum current. The bigger it is, the better.

Power: This indicator determines whether the cable can use to connect the device and whether the device will work without causing power surges.
