Glossary
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%.
