How to choose the right welding machine

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

Transformers:

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.

Rectifiers

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:

  • Significant dimensions and large weight, which negatively affects mobility.
  • The operation depends on the voltage of the electric current.
  • Increased electricity consumption.
  • Semi-automatic machines
  • Argon is mainly used in the devices, but carbon dioxide can also be used.

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.
  • At home.
  • In vehicle maintenance centers

.This type of welding machine has the following advantages::

  • It can be used for metal that is less than 1 mm thick.
  • High quality of processing.
  • During use, the metal is practically not sprayed.
  • High performance.
  • Among the disadvantages, the following points are highlighted:
  • High consumption of materials-gas and wire.
  • The high cost of both the unit itself and consumables.
  • Even beginners can use it. This explains the demand for devices.

The advantages of devices:

  1. Easy to use.
  2. Small size and weight.
  3. High performance and reliability.
  4. The metal is practically not sprayed.
  5. High quality of processing.

  7. compared to previous units.
  8. Quick ignition.
  9. Arc stability.

Design of inverters:

  • An electronic circuit.
  • 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 are recommended 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

Initially, it was planned that the device would be used 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.

Devices for plasma 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 be used 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 is recommended to focus on such moments:

The presence of a pulsed 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.
