6 - HUMAN INTERFACE (HI) PRESENTATION
6.1 - CONTROLS AND OPERATIONAL FEATURES
The HUMAN INTERFACE (HI) is located on the front panel of the unit
(Ref.1-Fig.2) and is the mind of machine.
IMPORTANT: WHEN THE MACHINE IS POWERED (REF.A-
FIG.3) LIGHTS UP THE GREEN POWER ON LED (REF.10-FIG.8)
IN CONJUNCTION WITH ONE OF THE INPUT VOLTAGE LEDS
(REF.7,8,9-FIG.8) TO INDICATE THE CHARACTERISTIC OF THE
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
■
time the key briefly:
ܟL = soft arc: for welding with a low spatter presence.
ܟM = crisp arc: for welding with an increased arc stability.
ܟH = hard stick: for an aggressive welding in difficult operative
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.
Ref.13. Selection key for two functions:
SET: press SET switch pad each time briefly until desired process
■
LED is illuminated and use in conjunction the Encoder Control Knob
to set values for that function.
Remote control: allows operator to use remote amperage control
■
if desired. Connect the remote control device to the remote 10
pins receptacle on the front of the machine (Ref.6 – Fig.2). To
activate or deactivate the device press the key once for 5 sec.
Attention: the maximum welding current from remote will be
that set with the Encoder Control Knob (Ref.3).
HUMAN INTERFACE (HI) PRESENTATION
Ref.14. Red LED lights up with power source in idle mode or faulty (output
voltage < 15V).
Idle mode for:
■
ܟVRD ON at end of welding: this function reduces the voltage at
the output leads.
ܟYellow LED ON (Ref.16): this indicator lights up when the
machine is overheated and the output has been disabled.
ܟOutput leads in short-circuit (remove the short circuit).
Defectiveness for:
■
ܟFault in supply / control stage.
ܟFault in output stage.
ܟPower inverter broken.
Ref.15. With red LED lit, use the Encoder control knob to adjust the welding
current. The ammeter (Ref.2) displays the pre-set value and the
amperage while welding. The welding current LED (Ref.15-Fig.8)
normally is turned ON; it's OFF only when the Hot Start or Arc
Force function is activated.
Ref.16. Yellow LED will turn ON when the machine is overheated and the
output has been disabled (also Ref.14 lights up). This normally
occurs when the duty cycle of the machine has been exceeded.
Leave the unit ON to allow the internal components to cool. When
the yellow indicator turn OFF, normal operation is again possible.
Ref.17. Red LED lights up by the selection key (Ref.13) to allows the Arc
Force to be set from 0 to 75 in steps of 1 by the Encoder Control
Knob (Ref.3). Setting 75 is the strongest Arc Force. The set value
is displayed on the meter (Ref.2). The Arc Force must be set when
welding is not being carried out.
Ref.18. Red LED lights up by the selection key (Ref.13) to allows the Hot
Start to be set from 0 to 99 in steps of 1 by the Encoder Control
Knob (Ref.3). Setting 99 is the strongest Hot Start. The set value
is displayed on the meter (Ref.2). The Hot Start must be set when
welding is not being carried out.
Ref.19. Welding process selection key: MMA or TIG with Lift Arc.
