FRONT PANEL
Fig. 6
• PANEL RESET.
To carry out a reset of the parameters
set on the front panel, and load the default values, keep
the S2 and S4 keys held down together during the start-
up of the machine.
• L1:
LED Output power on.
When this LED is lit,
it means that there is power at the output socket of the
welding machine.
• L2:
LED alarm.
When this LED is lit, it means that
the thermal cut-out for overheating of the machine has
triggered. In this case, we suggest you leave the machine
on to allow the fan to cool the machine better and more
quickly.
When the machine is turned on, L2 remains on for 3
seconds during which there is no voltage on the welding
machine outlets.
All the displays show the writing AL.H.
• D1:
Display.
Allows you to display the value for the
weld current set or the value of the welding parameter
chosen with key S2, both in adjustment from the panel
(INTERNAL) and from the remote control (EXTERNAL).
• E1: Encoder to alter the values for the parameters
shown on the display.
Allows you to change the value
shown by the display for the welding current (only by
adjustment from the panel) or the value for the welding
parameter chosen with key S2 (by both INTERNAL and
EXTERNAL adjustments).
• J1:
6-pole
military
connector
for
REMOTE
CONTROL.
It can be connected to a potentiometer
remote control or foot control; in the last case, only the
two-stroke lift-arc (2T) and the two-stroke HF (2T HF)
processes can be selected. The regulation of the
ascent/descent ramp time is not available.
• L25:
LED EXTERNAL.
When this LED is off it
shows that adjustment from the panel (INTERNAL) has
been selected, while if the LED is on it shows that
adjustment from the remote control (EXTERNAL) has
been selected.
• S1:
INTERNAL-EXTERNAL selection key.
By
pressing the S1 key, you can select adjustment of the
welding current from the panel or from the remote control
.
If a pedal remote control is used it is possible to set the
maximum and minimum value of the welding current; with
E1 the maximum current is set, while by pressing the S1
key for two seconds the minimum current can be set as a
percentage of the set maximum current, visualized as
cXX (XX = percentage value, from 1 to 90%).
• S2: WELDING PARAMETERS selection button.
The diagram shows the welding parameters that can be
selected clockwise by pressing key S2. Every time the
key is pressed a led in the diagram lights up to confirm
the dislpay of that parameter on the screen. Once a
parameter has been selected, turn the encoder to change
its value. The new value will be automatically stored. The
key is enabled only in the TIG mode. In the MMA mode
welding current led L3 remains on all the time.
To better understand the function of the parameters
described below, referred to the following graph.
