§3.2 Duty cycle & Over heat
The letter “X” stands for 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 over-heat, the IGBT over-heat protection unit inside it will output an
instruction to cut output welding current, and brighten 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..

arc welding machine, the handles are installed at the top of
machine to move it. The machine needs immobile equipment to fix to avoid sliding.
When using forklift, its arm length must be long enough to reach the outside so as to
ensure lifting safely.
The movement may result in the potential danger or substantive hazard, so please make
sure that the machine is on the safe position before using it.
