How to choose a welding generator? Advice

If you are planning to buy a welding generator, then, probably, you will face the problem of his choice. It's not easy to do, because many products are produced today, with their own distinctive features. In this article we will show you how to choose a welding generator, today the situation has changed dramatically.

Gasoline and diesel generators

Welding generator – This is a special device, which connects the welding machine with the generator. Today in the construction market you can find welding generators with diesel and gasoline engines. The only difference – This is the type of fuel used. If you decide Buy a welding generator on gasoline – you can find really inexpensive equipment. He is compact, but relatively weaker than the diesel generator. At the same time, the welding generator, diesel engine, withstands much larger loads.

Its useful to note, that the cost of welding generators is quite high. In some cases, to save money, many acquire a separate generator and welding machine. On the other side, Welding power plant is completely suitable for welding work. If you bought a separate generator and welding machine, there is a chance not to guess with power. Although here everyone decides for himself.

Remember, that electric welding gives a large load on the generator, Therefore, not every power plant will withstand the work of the welding machine. In order to avoid unpleasant consequences to its choice, you should take it very seriously.

Take choice: constant or alternating?

All generators can be divided into constant and alternating generators. DC devices are characterized by a stable voltage, Therefore, you can get a high -quality welded seam. These generators are suitable for welding high -quality structures using various types of electrodes.

The design of alternating current generators is easier, Therefore, they are cheaper, than DC devices. But with their help it will not be possible to get such a seam quality, as when using a direct current generator.

The generator work cycle

Working cycle at the load of the generator – This is the percentage of the combustion time of the arc and the total time of the machine. Each device corresponds to a working welding current of the required value, which the device can give out for a long time without overheating.

Consider an example.

• Europower EP200X generators produce working current 200 And with a working cycle 35%, And with a working cycle 60% The working current is 150 A. Theoretically, the duration of the welding cycle can be 10 minutes, After which it can be repeated a significant number of times until the thermal regime is reached.
• The generator exceeds the permissible temperature limit. In the considered example of the current 150 And well 60% mean, that with this generator it is possible to weld the current before 150 But no more 6 minutes. After that, the generator must cool at least 4 minutes. Now you can repeat a 10-minute cycle, in which the car will work 6 minutes and cooled for 4 minutes.

If you want to choose the right welding generator , It is important to take into account many nuances. On the other side, You will receive an unit, which will meet your needs more, than other solutions.
