How to choose a semi-automatic welding machine?

When choosing a semi-automatic welding machine, first of all you need to decide on the scope of its use..

Inexpensive devices are suitable for household use, but for a small workshop it is better to choose more expensive models with expanded functionality and advanced technical characteristics.

The main criteria for choosing a semi-automatic welding machine include:

1. Voltage and output current adjustment range . For domestic use, a device with modest characteristics will be sufficient. But, if you plan to use the device to perform a large volume of work with wire of the maximum permissible diameter, it is better to choose a device with a high level of outgoing current.
2. Power . The lower this indicator, the less network subsidence will occur during welding. To ensure that the device can operate even from a network with an unstable voltage, it is better to choose a model with modern IGBT or MOSFET transistors.
3. Dimensions and weight . This criterion is especially important if the welding is planned to be frequently transported or stored in a small room. But it should be borne in mind that compact devices usually have reduced power, although they are quite sufficient for domestic needs.

Be sure to take into account the possibility of connecting the device to a household electrical network, as well as the type and thickness of the metals with which they will work.

The best manufacturers of semi-automatic welding machines

The manufacturer's reputation is no less important than the number of functions available. By choosing equipment from trusted brands, you automatically rely on quality. We recommend equipment from the following brands:

• Fubag (Germany) – sells a wide range of welding machines and related accessories. Semi-automatic welding machines from this company have high technical parameters and are moderately expensive.
• Svarog (Russia) is a joint Russian-foreign brand. Large dealer networks guarantee maximum, high-quality customer service.
• RESANTA (Latvia) is a leader in its segment. Inverters are reliable, economical, and durable.
• ELITECH (Russia) – the main production facilities are located in Belarus and China, it has its own quality control system.
• Aurora (Russia) - provides an official guarantee for all equipment; production facilities located in China are used for assembly.

The cost depends not only on the brand, but also on the set of functions. If you want to save money, choose a simple model from a well-known brand.

Which semi-automatic welding machine is better to buy?

The wire in the tool performs two functions simultaneously. It serves both as a filler material and as one of the contacts for igniting the arc. This allows continuous seams up to four meters in length. Convenience of operation is ensured by the absence of a burning electrode that requires constant replacement.

The main elements of the device are:

• inert gas cylinder,
• filler wire spool,
• gearbox,
• burner,
• power supply.

Depending on the type of instrument, the features of its design may vary slightly.

When choosing a machine, you need to pay attention to the wire diameter and welding current. These indicators depend on the thickness of the metal being processed and on each other, since a small-diameter wire with a high current will quickly melt before reaching the part being connected:

• For metal up to 1 mm thick, the wire diameter must be at least 0.6 mm, and the current strength must be from 30 A.
• Metal elements of large thickness (from 5 mm) require wire with a diameter of at least 1 mm and a current of 150 A for processing.

The performance of the device is affected by power consumption. For domestic use, it is recommended to purchase tools with a power of no more than 4000 W. This will protect the network from overloads, while allowing you to process metal up to 3 mm thick.

For private workshops, it is recommended to use devices with a power of 7000 W or more. With their help it is possible to manufacture gates, doors and other complex structures.

Additional important features of the device include the length of the welding torch, inductance adjustment, support for automatic shutdown and digital display.
