(5) Protection Feature
When a temperature of the welding output control component(s) is exceeded, the output is
automatically reduced to protect the component(s). An “OVERHEAT” lamp is also ON and flickered.
When AC output is not available, follow the procedure below.
Note: Stop operation immediately if such case may happen until the overheat lamp will turn off.
When this case may repeat, reduce duty cycle or current to be used.
