The welding gas generator can be used for work in "wild" conditions. This may be your cottage, areas remote from the mains, or construction sites. Connecting a transformer is undesirable, because power surges can cause damage to the power plant.
On sale today you can find two types of generators, in this case we are talking about devices that are used in tandem with welding machines. Such generators can be synchronous or welding. The former are voltage sources to which household appliances and a welding inverter can be connected.
As for welding generators, they are compact devices that provide for a built-in welding machine. Such units take up little space, so they are convenient to take with you. Gasoline generators with a welding machine have a certain power, so the consumer has to choose the right model.
Choosing a generator for a welding machine: basicFeatures
Before you decide which generator you need, you need to pay attention to the power. The generator must be more powerful than the inverter. The power reserve will allow the device to operate in normal mode, while the unit will not operate at its limit. In order to determine how much power a gas generator is needed for a welding inverter, you must find out the maximum current consumption. It can be found on the case of the device, it is designated Imax.
This parameter can be considered on the example of a unit with Imax 23A. Power should be calculated according to Ohm's law. To do this, the value mentioned above is multiplied by 220, as a result, it will be possible to obtain 5060 watts. 30% should be added to this figure, in the end you will get 6600 watts. This is the approximate power of the generator.
When choosing a gas generator for a welding inverter, you must also take into account the diameter of the electrodes. It must match the power of the device. For example, if the diameter is 2 mm, then 2.5 kW will be enough. If the value mentioned above increases to 3 mm, then the generator power will be 3.5 kW. Power requirements vary by model.
The consumer should also pay attention to the voltage of sockets. It must match the inverter type. If a household unit is available, then a 220V socket will be enough. If we are talking about three-phase powerful inverters, then you will need a socket with a voltage of 380V. Experts recommend paying attention also to the case. If you often have to take the station with you, then you should prefer a compactmodel with wheels. A positive feature of gasoline units is that they are usually smaller and lighter than diesel counterparts.
Select generator with welding function
The welding gas generator will have excellent durability if the design is equipped with cast iron sleeves. The service life of such devices is approximately 1500 hours. As for their aluminum counterparts, they can fail 3 times faster.
On sale today you can find inverters that have the function of power factor correction. They are great for working from generators, as they are able to operate at low voltage. If you want to choose just such a model, then you should pay attention to the marking where the PFC prefix should be.
In general, welding gas generators are designed to work with rest breaks. If you want to work many hours every day, then the diesel model should be preferred. When choosing a device for recreation and summer cottages, you must purchase a model whose power is in the range from 0.7 to 5 kW. Such devices are easy to transport and carry.
If the power reaches 10 kW, then the device is great for intensive work for 8 hours every day. One of the important parameters is the size of the fuel tank, as well as the presence of a soundproofing casing. Specialists especially emphasize the importance of the function, which makes it possible to start the welding gas generator from an electric starter.
Choosing equipment with valves located on top, you can compare it with diesel counterparts in terms of the quality of the energy released. Such units provide high performance, low noise, durability and compactness.
The purchase of such a generator is advisable if you plan to carry out work on a construction site, where you periodically need to supply a powerful flow of energy. When equipment is purchased for a cottage or an entire enterprise, it is better to consider models whose power varies from 10 to 20 kW. These units are usually equipped with an automatic start option and can be used as a permanent installation.
FUBAG WS 230DC ES station specifications
If you need a gas generator for welding, then one of these models can be considered as an example. This is FUBAG WS 230DC ES, perfect for solving the tasks that are set for the installation or construction team. The fuel tank provides 9 hours of continuous operation, which is true at 75% load.
Starting the station is quick and easy with an electric starter. The current is regulated in a wide range: from 50 to 230A. This unit connects metal workpieces using arc welding with stick electrodes. Their diameter can vary from 1.6 to 5 mm.

The design is equipped with a reinforced metal frame, which is coated with paint to avoid corrosion. The case has damping pads that reduce the level of vibration during operation. The described gasoline generator for welding weighs 97 kg. The fuel tank holds 25 liters. The design is equipped with an oil sensor.
What else to look for
The dimensions of the device are 722 x 530 x 582 mm. The noise level during operation reaches 77 dB. Engine power is 13 liters. with. The device works due to a four-stroke engine. It has a fuel level indicator. Starting the power plant can be done using an electric or manual starter.
Characteristics of the welding generator brand "Caliber" BSEG-5511
In order to decide which gas generator is better, it is worth considering several models. Among others, the Caliber generator can be distinguished, which will be discussed below. This device is a versatile unit that will be a great helper in a car service or on a construction site.
Additional Features

Conclusion
Everyone knows that when carrying out welding work, one cannot do without electricity. However, it is not always possible to connect to the network. But not all equipment can work from a conventional outlet. Connection to high-voltage wires requires obtaining the necessary permits.
In order to solve this problem, you can use an electric generator. Quite often, consumers choose its gasoline variety, because it has a lighter weight and more compact dimensions compared to diesel counterparts. Today, every team of professionals has such equipment in their tool kit. But if you are an ordinaryconsumer, then it is necessary to approach the choice of a gasoline generator even more carefully so that the power reserve is sufficient and the price is acceptable. After all, the generator is quite expensive equipment.
