Welding machine transformers

October 28, 2020

Transformers are used for various types of welding work. They are powered from the electrical network and convert alternating voltage, which is reduced to the required value. Today's rating contains a list of the best transformers for welding machines , designed for domestic and professional use.

The correct choice of the device and the calculation of the necessary indicators depend on the purpose of its use. One of the main characteristics of a transformer for a welding machine is the maximum current capacity.

For small household work, such as processing fences, netting or sheds, 160 amps are sufficient, while in large workshops it is recommended to use transformers with a capacity of at least 200 amps. This characteristic also affects the required diameter of the electrode.

Welding transformers are used when high-quality welding is not required, for example, when processing ferrous metals. Such devices are distinguished by economical electricity consumption and a high efficiency coefficient - about 70-80%.

Western ARC 130

The model's distinctive features include its light weight and ease of use. With reduced voltage, the device operates at up to 198 V and processes metal with a thickness of approximately 4 mm.

Thanks to the built-in fan of the transformer, it is reliably protected from overheating and short circuits. The current capacity is regulated in the range of 80-130 A.

Advantages:

Weight - 10.6 kg;
Reliable device;
Long service life.

Disadvantages:

Short cable.

Awelco Club 1850

As a power source, the model uses an electrical network with a voltage of 220 or 380 V. Metal processing is carried out using electrodes with a thickness of 1.6-3.2 mm. The transformer of the welding machine also has an overload protection function.

The current range varies from 60 to 150 A, which allows you to achieve high-quality welding. A handle and removable wheels are used to transport the 18 kg device.

Advantages:

Low price;
Stable work;
High quality welding;
Convenience of transportation.

Disadvantages:

When working at high load, it gets very hot.

Telwin Eurarc 522

The model is equipped with a power regulator and a thermostatic overheating protection mechanism. The transformer can work with alkaline electrodes with a diameter of 1.6 to 6 mm, which allows you to weld metal up to 24 mm thick.

The device uses 220 or 380 volts as the main power source. The handle and wheels make it possible to move the transformer weighing 81 kg without any problems.

Advantages:

High power;
Maximum current strength - 400 A;
Ease of movement.

Disadvantages:

High price.

Kaviki TDM-252 U2

The welding machine transformer is a lightweight and powerful device that operates stably from a 380 V network. The current range is approximately 50 to 250 A, which allows you to weld metal about 8 mm thick.

The device's power is 12 kW. At maximum load, the device's durability is 60%, which ensures long-term and stable operation without interruptions.

Advantages:
