8.1 Indicator Light
The indicator light is provided to indicate when the Viking is connected to the Mains supply
voltage.
WARNING 4
When the light is lit, the machine is connected to the Mains supply voltage and the internal electrical
components are at Mains voltage potential.
8.2 Standby/Coarse Voltage Control Switch and Fine Voltage Control Switch
The Coarse Voltage Control switch turns off the fan and auxiliary power in the STANDBY
position. It sets the voltage level to the welding terminals in the remaining positions, increasing
the voltage as it is rotated in the clockwise direction. The Fine Voltage Control switch increases
the voltage (in smaller increments than the Coarse switch) as it is rotated in the clockwise
direction.
CAUTION 2
The Coarse & Fine Voltage Control switches MUST NOT BE SWITCHED during the welding process.
8.3 Digital Ammeter and Voltmeter (Optional)
Where fitted an average reading ammeter and voltmeter is provided to allow accurate monitoring
(5% tolerance) of welding current and voltmeter to facilitates precise welding condition
adjustment. Refer to section 11.1 on page 27 for the Improved Current Accuracy Calibration
Procedure for the Digital Meter.
Value displayed for 157 Amp Value displayed for 23.4 Volts
Figure 5 - Examples of the digital read outs
The Digital Meter will display both welding current and voltage. To toggle between the current
and voltage readings depress the push button switch mounted below the meters display. See
Figure 5 for an example of current and voltage display.
