TOP 20 best semi-automatic welding machines for 2022

Why do you need semi-automatic welding if there is an automatic machine?

Despite the technology and similar name, the devices have obvious differences. When using an automatic machine, the user only needs to set the functions, that is, configure the device, and the machine itself will do the necessary work. With semi-automatic welding, the user does the work himself and also sets up the machine. In automatic mode, the semi-automatic machine only feeds welding wire.

Many users wonder why use semi-automatic welding if it is more convenient to use an automatic welding machine. The choice of welding depends on the conditions and scale of the job. Semi-automatic welding is mainly used, this is due to the fact that many people use the tool for small jobs. Automatic machines are needed only for professional purposes for large continuous work. In addition, automatic equipment is expensive and requires special knowledge to configure. The welding process is the same for both types, the only differences are in user participation, functionality, power and cost.

Design and principle of operation of a semi-automatic welding machine

Semi-automatic welding machines are distinguished by their high productivity. Unlike other devices, they have a built-in wire feed unit, which serves as a filler material and at the same time one of the contacts for igniting the arc. Thanks to this, it is possible to create continuous seams with a length of 2-4 meters in various spatial positions.

The device has:

Gearbox.
Cylinder with inert gas.
Spool of filler wire.
Feeder.
Burner with contact elements and control key.
Dashboard.
Power supply.
Burner sleeve with cable duct, supply wires, internal gas hose.
Ground cable with clamp.

Principle of operation. The operating current is emitted by an inverter device, which converts the alternating voltage of a conventional network into direct current. In this case, the value of V decreases and A increases. The equipment has two contacts (+ and -), one of which is connected to the metal being welded. Connected to ground should always be negative.

“Plus” is the entire burner hose wire. A cable is supplied through it, to which the voltage is transferred by a special contactor. Touching the end to the workpiece initiates an arc. The wire melts like a regular electrode, creating a weld pool. At the same time, the edges of the metal melt and, mixing with the additive, a seam is formed. By adjusting the diameter of the wire, you can weld metal of various thicknesses. The nozzle has holes for supplying protective gas, which, instead of lubricating the electrode, creates a cloud of air that prevents the interaction of the liquid metal and the external environment. The nozzle at the end of the burner directs the gas flow in the correct direction, preventing it from dissipating randomly.

Types of semiautomatic welding machines and their differences

There are three types of welding machines. Each of them has its own advantages and disadvantages; let’s consider them in more detail.

Household

Household models have low power, so they have an affordable price. At the same time, they are great for work in the country or in the garage. With their help, you can attach a patch to a car body, weld an underwater tank or fuel tank, or make a gate yourself.

How do semi-automatic welding machines differ from other machines?

Unlike manual arc machines, in addition to the current converter, semi-automatic machines have one more element - a mechanism for automatically feeding the filling wire during operation. The result is a stable and uniform arc and an extremely high quality weld.

Working with semi-automatic welding machines is distinguished by a number of features such as:

no time spent on calcination and drying of electrodes;
possibility of applying long solid sutures;
the presence of an automatic control function for the speed at which the wire is fed in accordance with the characteristics of the arc;
constant distance from the electrode to the metal of the product;
cleanliness of work;

How to choose a good semi-automatic welding machine

For a cottage, garage or private home, a device with a power of about 3 kW with a maximum welding current of 120-160 A will be sufficient. Select the minimum value based on the thickness of the metal being welded. PV is 30-40%.

For a small workshop with a commercial focus or service station, buy more powerful models (4-5 kW with a peak current of 160-200 A).

For professional use, you need a powerful model with a current of over 200 A, an on-time of 80%, preferably liquid cooling. Power can reach 7-8 kW or more. MMA support and a Euro connector are required.

When choosing, you should also take into account the characteristics of the device. Let's take a closer look at them.

Wire diameter and current

Metal thickness	Current	D wire
0.5-1 mm	10-30 A	0.6 mm
1.2-2 mm	45-100 A	0.8 mm
2.5-4 mm	120-200 A	1-1.2 mm
5-8 mm	150-350 A	1.6 mm
9-20 mm	300-500 A	1.6 mm

Choosing the right shielding gas

To protect the weld pool from atmospheric gases, inert gases (argon), carbon dioxide, or a mixture of them are used. The cylinder is connected to the burner and gas is supplied from it. It is selected depending on the welding conditions:

Carbon dioxide is inexpensive, suitable for non-critical connections that will not experience significant loads, welding thin ferrous metals with a thickness of about 1 millimeter. When working, the seam turns out scaly and unaesthetic.
Argon is an expensive gas for welding alloys and stainless steels, titanium, aluminum, copper, and alloys based on them.
A mixture of carbon dioxide and argon (usually in a ratio of 1 to 5) - provides a smooth and stable arc, a uniform and beautiful connection without the need for further processing. Suitable for working with alloy steels and steels with high carbon content.

Important! To operate without shielding gas, expensive flux cored wire is used. By melting the arc, it protects the weld pool from atmospheric gases.

Semi-automatic switch-on duration (SF)

The ignition period (PV), the same load period (PN) or DC (duty cycle) - all the same parameter of the welding machine, is one of the main ones. It is this that directly determines the performance and indirectly the service life of the device. It is stated as a percentage indicating the portion (period of time) of the total welding cycle during which the machine can perform the job without interruption. That is, if PV=100%, then there is no need to pause work. If PV = 50%, then the welding duration is equal to the “rest” duration.

Pauses are necessary to cool the device to the permissible temperature, which rises sharply during the arcing period. The better the design and the more powerful the cooling system, the higher the PV.

Burner cooling

There are 2 types of device cooling:

Air . The device is cooled by fans that circulate air through the device body. The burner operates without cooling. Depending on the model and manufacturer, the number of fans can vary from 1 to 3. The disadvantage of such cooling is that even if the source itself is perfectly cooled, the burner will still overheat and you will have to pause work.
Liquid . Cooling is focused on intensive work as well as work in high ambient temperatures. For example, if it is +30 in the workshop, the device will not benefit from the circulation of hot air. On liquid cooling devices, in addition to fans, a coolant reservoir is installed. A liquid of a special chemical composition is poured. This type of cooling also optimizes the cooling of the welding torch.

Important! The burner must match the type of device. For example, if you put a liquid-cooled torch into a torch designed for air cooling, it will overheat because it does not have additional liquid cooling.

Possibility of welding without gas

Semi-automatic welding without gas allows you to achieve the required level of melting of a metal surface with a wire diameter of 0.8 to 2 millimeters. Thanks to the special composition of the flux, semi-automatic welding allows you to create a high-quality and durable seam when connecting metal parts of any thickness, which indicates the high efficiency of the welding method.

Among the advantages are the following:

the semi-automatic welding machine is compact in size and lightweight, you do not need to buy hoses and a gas cylinder with a reducer for welding;
the compactness of the equipment allows it to be used in hard-to-reach places - it can be used to work at heights, as well as in narrow corridors or rooms;
the welding process is performed quickly and accurately;
welding is formed under visual control through a protective mask;
you can choose the temperature and power of the electric arc depending on the type of metal;
wire can be selected with different types of filler.

The disadvantages of semi-automatic welding include the following:

the cost of flow wire is quite high;
welding wire has a certain degree of fragility and therefore requires careful handling during operation;
in accordance with the composition of the flux powder in a semi-automatic welding machine, it is necessary to correctly select the desired operating mode, which causes difficulties for beginners;
when using welding flux, slag is formed during the formation of solder, which must be cleaned;
a semi-automatic machine has the ability to change the polarity of the connection, but how to use it and for what purpose - this often raises doubts among inexperienced welders.

Operation at reduced input voltage

For the device to operate fully, it must receive sufficient voltage. This parameter ranges from 140 to 220 V.

Some models can only operate on 220 V, and a drop in the network leads to a weak arc and the impossibility of welding. Such semi-automatic devices should be purchased only where there is a stable voltage or a stabilizer.

Devices with a value of 140 V are suitable for rural areas or mobile activities where network parameters are unknown or the voltage frequently fluctuates. This is a good choice for a country house or garage.

Features of choosing a semi-automatic device for domestic use

Any home tool runs on electric current with standard parameters: voltage - 220 V, frequency - 50 Hertz. It is necessary to find out whether additional modes are needed, since there is no point in paying for additional functions. To do this you need:

find out the volume of the cylinder so that there are no difficulties when transporting welding equipment;
look at consumption parameters, there are models with low network load;
find out the method of wire feeding (pulling or push-pull), the number of guide rollers, feed regulation (jumping, smooth), the degree of automation of the feeding process;
look at the switch-on time; for semi-automatic household welding machines, the figure of 20% is quite acceptable;
set the operating current adjustment range;
look at the filler material supply system: the closed type is more convenient, you are less likely to have to clean the guide channel, there will be no contamination on the cable;
find out if there is a short circuit protection system.

To choose a 220V semi-automatic welding machine, determine where it will work. For outdoor use, you need a transformer welding machine; for indoor spaces, choose an inverter.
