Further Controls Explained
LH Digital Multifunction Display (9)
Before welding this displays the setting selected or being adjusted using the control knob (24). During
welding it displays welding current. The parameter setting displayed is indicated by the LEDs beside
the display; Current (A), Saved Setting (JOB), Time (S), Percentage (%) and Frequency (Hz). If left
inactive for several seconds, display will revert back to main welding current setting.
RH Digital Multifunction Display (10)
Before welding this displays secondary functions and error codes. During welding it displays welding
voltage.
Multifunction Smart Control Knob (24)
Press knob to navigate through the control panel parameters not controlled by specific selector
buttons. Parameter/setting selected will be indicated by the LED on the control panel and the value
shown on the LH display (9). Adjust the parameter by turning the knob. Access the job/program
store/ recall function by pressing and holding the knob.
Water Cooling System Error Indicator (12)
When using the integrated water cooler, the system is equipped with a pressure sensor. If the coolant
pressure is insufficient, this indicator will light and the welding output will not be able to be active, in
order to protect the torch and cooling system.
Alarm Indicator (13)
Lights when over voltage, over current, input phase loss or electrical overheating (due to exceeding
duty cycle) is detected and protection is activated. When protection is activated, welding output will
be disabled until the safety system senses the overload has reduced sufficiently and indicator lamp
goes out. May also trigger if machine experiences an internal power circuit failure.
