A. Power Switch: It turns ON / OFF the input power to
the machine.
B. Input cable: This machine is provided with a plugged
input cord. Connect it to the mains.
C. Fan: This machine has a F.A.N. (Fan As Needed)
circuitry inside. The machine automatically turns it
ON or OFF. This feature reduces the amount of dirt
which can be drawn inside the machine and reduces
power consumption. When the machine is turned ON
the fan will turn ON. The fan will continue to run
whenever the machine is welding. The F.A.N. feature
is active after that the machine doesn't weld for more
than 10 minutes, the fan will be turned OFF and, at
same time, the output will be disabled. To restore the
output and the fan, simply restart to weld.
