3.2 Duty cycle & Over heating
Duty cycle, which is defined as the proportion of the time that a machine can work continuously
within a certain time (10 minutes). The rated duty cycle means the proportion of the time that a
machine can work continuously within 10 minutes when it outputs the rated welding current.
If the welder is overheating, the IGBT over-heat protection unit inside will output an instruction
to cut output welding current and light up the over-heat pilot lamp on the front panel. At this
time, the machine should be relaxed for 15 minutes to cool the fan. When operating the machine
again, the welding output current or the duty cycle should be reduced.
3.3 Welding polarity connection
3.3.1 MMA
Choosing the connection of DCEN or DCEP is based on the electrode type. Different electrodes require
different polarity. Please refer to the electrode manual.
