10.2.6 Automatic Stop of Fan
The cooling fan automatically stops in 10 minutes after welding is finished and automatically
starts turning when welding is started. When powering the welding power source, the cooling
fan is also turning but automatically stops in 10 minutes when no operation is carried out.
10.2.7 Reduction of Fan Noise
When the welding power source is not temporarily in use, the rate of fan rotation decreases
so that fan noise can reduce. This function works only for 250 A or less output current.
