If you plan to buy a welding generator, most likely you are faced with the problem of its choice. Since today a variety of products with their own distinctive features are produced, this is not at all easy. let’s consider, how to choose a welding generator.
Gasoline and diesel generators
The welding generator is a special device that combines a welding machine with the generator. Today in the construction market you can find diesel and gasoline welding generators. They differ among themselves exclusively in the type of fuel consumed. When choosing a gasoline welding generator, you can get the unit at a low price. It is compact, but has a relatively small work resource. At the same time, a welding generator that runs on a diesel engine can withstand much greater loads.
It should be noted that the cost of welding generators is quite high. In some cases, for the sake of cost savings, a decision is made to purchase a separate generator and welding machine. On the other hand, a welding power station is a device that is fully suitable for welding. When buying a separate generator and welding machine, there is a chance not to guess with their power. Although here everyone decides for himself.
Remember that electric welding will become a high load for the generator, so not every power plant can withstand the operation of the welding machine. In order to avoid unpleasant consequences, it is necessary to take her choice very seriously.
Current selection: direct or alternating?
All generators can be classified into those that operate with direct and alternating current. DC devices are characterized by a stable voltage, due to which it is possible to obtain a high-quality weld. These generators are suitable for high quality construction welding using various types of electrodes..
The design of alternators is simpler, therefore, they have a lower cost than a DC device. But with their help, it will not be possible to obtain such a quality of the weld as when using a generator with a direct current.
Generator duty cycle
The duty cycle when the generator is loaded is a percentage of the time of combustion of the welding arc and the total operating time of the device. Each unit corresponds to a welding operating current of the required value, which the unit can generate for a long time without overheating.
Consider an example. Europower EP200X generators produce a working current of 200A with a duty cycle of 35%, and with a duty cycle of 60%, the operating current is 150A. 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 of the generator exceeds the permissible temperature limit. In the considered example, a current of 150A and a duty cycle of 60% mean that with this generator it is possible to carry out welding with a current of up to 150A for no more than 6 minutes. After this, the generator must cool down for at least 4 minutes. Now you can repeat a 10-minute cycle in which the device will work for 6 minutes and cool down for 4 minutes.
