Turns on when duty cycle is excessive or flow for the water cooled torch is insufficient. It is reset when
a flow of specified value or more is supplied.
Turns on when the temperature of welding power source is too high.
7. Input volt warning lamp
Turns on when input voltage is unusual (excessive, too low or be short of phase).
8. A-V display switch
Control the display of the digital meter
9. Digital meter
Display current or voltage at digital meter.
10. Pulsation switch
