6.1 - CONTROLS AND OPERATIONAL FEATURES

The HUMAN INTERFACE (HI) is located on the front panel of the unit

IN CONJUNCTION WITH ONE OF THE INPUT VOLTAGE LEDS
    
MAINS CONNECTED TO THE UNIT.
For all front panel switch pad controls: press
switch pad to turn on light and enable function.
At times the information on the state of the unit
are given simultaneously by two LEDs; read
section 6.2. below.
The following pre-settings and visualizations are available (see
Fig.8):
Ref.2. Ammeter display actual amperage while welding. Meter also
displays preset parameters for any of the following units of measure
when they are active: Amperage, Hot Start. Arc Force and VRD. The
corresponding LED, will also illuminate.
Ref.3. Encoder Control Knob: use it in conjunction with applicable front
panel function switch pad to set values for that function.
Ref.10. Green LED blinks in conjunction with Ref.11. with abnormal input
voltage or phase loss.
Ref.11. Red LED lights up or blinks in conjunction with Ref.10. with
abnormal input voltages or phase loss.
Ref.12. Selection key for two functions:
Arc length: to set the arc length in MMA welding process, press each

L = soft arc: for welding with a low spatter presence.
M = crisp arc: for welding with an increased arc stability.

conditions or with cellulosic & aluminum electrodes.
VRD: some national regulations or special work environments
require the use of reduced no-load voltage. To set the VRD function
ON or OFF press the key once for 5 sec. When activated the VRD
function is signaled on the display with the letters "Urd" each time
the unit is powered; if the function comes deactivated, on the display
disappear one by one the letters "Urd". As default from factory the
device is OFF.
