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.

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
has been disconnected.
2MENUS
The control panel uses several different menus. They are the main, measurement
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 measured
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 measured
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.

*) This function cannot be changed while welding is in progress.
**) When selecting electrode type, the start value is always 30 for arc force.
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 be
changed. The value is only displayed in the main menu.

Hot start Rutile electrode
Cellulose electrode Basic electrode
Explanation of symbols
Active symbol (dark background). Active means 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.
Value symbols
The value symbols are displayed in the settings menu for each function.
No arc force High arc force
Short hot start time Long hot start time
