1 INTRODUCTION
This manual describes use of the A4 control panel, which is installed in the Arc 4000i &
Arc 5000i power unit.
For general information on operation, see the power source operating instructions.

function pushbuttons. →.
4 First, second and third function pushbuttons
1.2 Remote control unit
Using a remote control unit, the primary parameters of the welding process can be
controlled from a device other than the control panel.
Machines with intergral control panels should have program version 1.21 or higher, in
order for the remote control to function correctly.
Control panel’s behaviour on connection of the remote control unit
S The display freezes in the menu showing when the remote control is connected.
Measurement and setting values are updated, but only shown in those menus in
which the values can be displayed.
S If a fault code symbol is displayed, it cannot be removed until the remote control unit
has been disconnected.

2 MENUS
The control panel uses several different menus. T hey are the main, m easurement and
settings menus.
2.1 Main and measurement menus
The main menu is always displayed immediately after the
machine is started. The menu shows the values which have
been set. If the main menu is displayed when welding begins, it
switches over automatically to show the m easured values
(measurement menu). The measured values will be displayed
even after welding has been completed.
The settings menu can be accessed without losing the measured values. It is only when
the knob is turned that the setting values are displayed instead of the m easured values.
2.2 Settings menu
Different values can be entered in the settings menu.
To access the settings menu, press , , or
.
When the power source is switched off and restarted, the last values to be set are
recalled.

Hot start
Hot start increases the weld current for an adjustable time at the start of welding, thus
reducing the risk of poor fusion at the beginning of the joint.
Arc force
The arc force is important in determining how the current changes in response to a
change in the arc length. A lower value gives a calmer arc with less spatter.
Current
A higher current produces a wider weld pool, with better penetration into the workpiece.
Irrespective of which menu is displayed, the setting value for the current can b e
changed. T he value is only displayed in the main menu.

Explanation of symbols
Active symbol (dark background). Active m eans that the function which the
symbol represents can be activated. New values can only be set when the symbol is
active.
Inactive symbol (light background). Inactive means that settings for the
function which the symbol represents cannot be changed. From the settings menu,
pressing an inactive symbol will return the machine to the main menu.
A dot in the upper right--hand corner indicates that “Hot start” is ON.

4 ARC--AIR GOUGING
Arc--air gouging involves the use of a special electrode consisting of a carbon bar with a
copper case. An arc is formed between the carbon bar and the workpiece, air is
supplied to blow away the melted material, and a seam is formed.

5 FAULT CODES
Fault codes are used to indicate that a fault has occurred in the equipment. They are
shown in the display in the form of a symbol as follows:
Fault codes are updated every three seconds. The upper numeral in the
symbol is the number of the particular fault code: see Item NO TAG. T he
lower figure indicates where the fault is:
0 = the control panel
2 = the power unit
4 = the remote control
The above symbol shows that the control panel (0) has lost contact with the power unit.
If sever a l faults have been detected, only the code for the last fault to occur will be
displayed.
Press any of the function keys in order to clear the symbol from the display.
Symbols may be steady or flashing, depending on the type of fault.
Flashing symbols are highlighted with “ o” in the list of fault codes.
