Duty-cycle ratings can be confusing, but we want to make duty-cycle less confusing. An 80% duty-cycle means that, out
of a ten (
10
)-minute time span (duty-cycle is always a ten (
10
)-minute time span, per definition, and this never
changes), the machine can weld for eight (
8
) minutes and then needs to idle with the cooling fan running for two (
2
)
minutes. Do not turn off or unplug the machine during this time.
However, these numbers change with the selected welding amperage and the ambient temperature. In reality, very few
can keep track of welding time like this, so we equipped the Invertig 313/400 AC/DC with a highly sophisticated over-
heat protection. The machine monitors the temperature of several vital internal components. Just before temperatures
venture outside of the safe operating range, the machine displays a message to the operator, the cooling fan continues
to run, and the welding output is shut down for four (
4
) minutes. This time allows the machine and internal
components to cool down to a safe operating temperature. There is no harm to the machine when the message is
displayed, and it does not matter how often this happens. There is no way to override this function.
