1.2 Remote control unit

Using a r emote control unit, the primary parameters of the welding process can be

controlled from a device other than the control panel.

Aristo machines with intergral control panels should have program version 1.21 or

higher, in order for the remote control to function correctly.

2 MENUS

The control panel uses several different menus. They 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 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.

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. T he value is only displayed in the main menu.

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 m achine to the main menu.

A dot in the upper right--hand corner indicates that “Hot start” is ON.

4 FAULT CODES

Fault codes are used to indicate that a fault has occurred in the equipment. T hey 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. The

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 several 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.
