Minimum input voltage

The minimum actual input voltage at which the welding machine remains operational.

Such information is useful primarily for working in unstable networks, where the voltage tends to “sag” a lot, as well as from autonomous power sources (for example, generators), which can also produce voltage below the nominal one.

Max. welding current

The highest current that the welding machine is capable of delivering through the electrodes during operation. In general, the higher this indicator, the thicker the electrodes the device can use and the greater the thickness of the parts with which it can work. Of course, it does not always make sense to chase high currents — they are more likely to damage thin parts. However, if you have to deal with large-scale work and a large thickness of the materials to be welded, you simply cannot do without a device with the appropriate characteristics. Optimum welding currents depending on materials, type of work (see "Type of welding"), type of electrodes, etc. can be specified in special tables. As for specific values, in the most “weak” models, the maximum current does not even reach 100 A, in the most powerful ones it can exceed 225 A and even 250 A.

Max. welding current (duty cycle 100%)

The highest welding current at which the machine is able to operate with a duty cycle of 100%.

See below for more information on the frequency of inclusion (PV). Here we recall that “100% duty cycle” means continuous operation, without shutdowns for cooling. Thus, the maximum welding current at 100% duty cycle is the highest current at which the machine can be used without interruption. Usually, this current is much lower than the maximum.

Duty cycle

The duty cycle allowed for the welding machine.

Almost all modern welding machines require breaks in operation — for cooling and general "recovery". The frequency of inclusion indicates what percentage of the time of the total work cycle can be used directly for work. In this case, 10 minutes is usually taken as a standard cycle. Thus, for example, a device with a duty cycle of 30% will be able to work continuously for less than 3 minutes, after which it will need at least 7 minutes of interruption. However, for some models, a cycle of 5 minutes is used; these nuances should be clarified according to the instructions.

In general, high frequency is required mainly for high-volume professional work; with a relatively simple application, this parameter does not play a decisive role, especially since you have to take breaks during work. As for specific values, the mentioned 30% is a very limited figure, typical mainly for entry-level devices. A value of 30 – 50% is also low; in the range of 50 – 70% is the majority of modern devices, and the most "hardy" models provide a frequency of more than 70%.

Max. electrode size

The largest diameter of the electrode that can be installed in the welding machine. Depending on the thickness of the parts, the material from which they are made, the type of welding (see above), etc. the optimal electrode diameter will be different; there are special tables that allow you to determine this value. Large diameter may be required for thick materials. Accordingly, before purchasing, you should make sure that the selected model will be able to work with all the necessary electrode diameters.

In modern welding machines, an electrode diameter of 1 mm or less is considered very small, 2 mm — small, 3 mm and 4 mm — medium, and powerful performant models use electrodes of 5 mm or more.

Mass cable

The length of the ground cable supplied with the machine.

The mass cable is a wire that is connected to the workpiece with a clamp. In other words, this is the second contact required to close the circuit during electric welding; connecting such a wire actually turns the workpiece into one solid fixed electrode (paired with a movable welding electrode). As for the length of such a wire, the longer it is, the farther from the connection point you can place the machine and the more freedom of movement the welder gets. On the other hand, excessively long wires create problems in storage and transportation, and often during work (you need to look for a place where to place the excess cable). In addition, freedom of movement can be ensured by increasing the length of the second wire — for the electrode holder or burner. Thus, the mass cable in modern welding machines usually has a length of 1.2 to 3 m (with some exceptions — both smaller and larger). This length allows you to comfortably place the device and at the same time does not create problems.
